SECTION 1 - INTRODUCTION

1.1 - GENERAL INFORMATION This manual provides user information for the basic routine operation of the Advanced Sensors Ltd

OIW-EX Series of Oil in Water Analyzer Systems. These analyzers are designed to conform to EN61010-1 2001 Part 1 and

are for use within Hazardous Areas to analyze the residual hydrocarbon content in Produced Water. The OIW-EX Series

is certified to the following specifications:

ATEX Directive (94/9/EC) Ex ll 2 G Ex d/de llB T4

Class I Div.1 Groups C & D T4 (USA and Canada)

Class I Zone 1 AEx/Ex d / de IIB T4 / T3 (USA and Canada; inc. Dual Seal Range)

Class I Div. 2 Groups A, B, C & D T4 (USA and Canada)

Marine Equipment Directive 96/98/EC

IMO MEPC 107 (49): ABS, USCG & BV

The analyzer software is MS Windows based for ease of use. Industry standard outputs available include: 4-20 mA

signal to output measurements over a configurable range and an Ethernet port over which the user can either receive

data or remotely control the unit. For complete listing of specifications see Appendix 1 page 87.

The oil content is measured using a technique known as Laser Induced Fluorescence (LIF). A laser penetrates through

the process water causing oil droplets to fluoresce. The resulting oil fluorescence value is used to calculate the

proportion of hydrocarbons in the water.

Contamination of the optical path, a result of oil adhesion, is a common problem with oil in water analyzers. To

overcome this problem a proprietary ultrasonic self-cleaning system has been incorporated into the analyzer which

operates at configurable intervals to accommodate the variable environmental conditions.

2.3 – OVERVIEW OF MEASUREMENT AND MEASUREMENT CYCLE 2.3.1 – Measurement with the OIW Analyzer

Fluorescence is a commonly utilised method for measuring the oil content in water; however measurement accuracy is

dependent on oil droplet size. Variation in droplet size may significantly affect the measurement reading despite

consistent oil content. Uniformity of droplet size and distribution are required to achieve a reliable ‘calibrated’ reading.

Therefore all OIW EX Analyzers are equipped with an ultrasonic transducer that serves the following purposes:

1. Breaking down the oil droplets into a uniform size.

2. Emulsifying effect to uniformly distribute the oil droplets within the water sample.

3. Prevention of sensor head and measurement chamber contamination.

Measurements are taken for every second the analyzer cycle is started and the data recorded in the Syslog files.

Scheduled sample measurement readings will appear in blue while all other normal flowing readings will be displayed in

black and out of range values in red. The OIW-EX Series has two methods of graphically displaying measurements with

configurable phase times to optimize performance for a given oil type. Users must login to select the method, selectable

from the ‘Water Line Options’ menu under the ‘General Configurations’ tab, and configure the phase times, from the

‘Measurement Cycle’ menu under the ‘Schedule’ Configuration Options.

The following 2 measurement display options are available:

1. Trending: Real time display of data points as recorded are displayed in the Graphical Display panel with a

red trending line connecting data points for reference. A vertical blue line on the graph will indicate values

obtained during scheduled measurements. When Trending is NOT selected only the scheduled

measurements will appear on the graphical display as vertical blue lines.

2. Trend Compensated: A compensation calculation will apply, obtained during the scheduled measurement,

to measurements in the next flowing phase. Trend compensation can be selected when significant

variations exist between trending and measured results. Possibly arising from differences in oil droplet

size and/or distribution.

2.3.1.1 – Valve Configurations

Standard configuration requires one valve to control the flow of produced water into the sample chamber as shown

below in Figure 8. Additional information for dual stream systems can be found in Section 6 p.84. Alternative

configurations are also available; please contact your local Advanced Sensors Representative for more information.

OIW-HBO-0002-EX-005



2.3.2 – Measurement Cycle Overview

The Measurement Cycle of the OIW-EX is configurable, set using numerical selection options from the ‘Measurement

Cycle’ menu, to accommodate oil types and therefore timing of each phase is variable. Figures 9 and 10 are graphical

representations of the measurement cycle, where Figure 9 provides a simplified overview while Figure 10 details the

processes in taking a measurement reading. The details of each phase will be described in the following Section: 2.3.3

– Measurement Cycle – Phase Descriptions p.17. Configuration of the measurement cycle using the OIW software will

be described in Section 3.2.3.1.2 – Schedule Configuration Options Menu p. 43.

OIW-HBO-0002-EX-005



2.3.3 – Measurement Cycle - Phase Descriptions

Begin the Measurement Cycle by selecting ‘Start’. Once the cycle has started the flow valve will open allowing process

water to begin flowing through the analyzer chamber assembly. The following sub sections will summarise in brief the

status of the analyzer events during flowing, cleaning and measurement phases.

2.3.3.1 – Phase 1 – Flowing

In this phase process water flows freely through the sample chamber, past the flow valve, and returns to the main

process pipeline as indicated by the red arrows in Figure 11. The flowing phase continues – as configured by the user

– until the valve closes in preparation for measurement. Once the measurement, or hold phase, is complete the flow

valve re-opens.

Figure 11: Standard flow valve fitted on the outlet side of the chamber assembly.

Status Display during FLOWING:

During this phase ‘FLOWING’ will appear in the status display with a countdown timer to indicate the remaining

scheduled flow time, as shown below:

Figure 12: Flowing display.

If Trending Enabled is selected: the current measurement reading will be displayed with a trend line in the graphical

display including vertical blue lines to indicate values for scheduled measurements.

If Trending Enabled is NOT selected: then the measurement reading will only appear in the Measurement Reading Area

of the Feedback Display Panel. No graphical data will be shown on screen but data will be recorded in the log file. Only

vertical blue lines will be visible to indicate values for scheduled measurements.

OIW-HBO-0002-EX-005



2.3.3.2 – Phase 2 – Cleaning

The cleaning phase occurs within the flowing phase clearing the measurement window and allowing the process flow to

clear debris from the chamber. Cleaning times are user definable to accommodate oil variations in process water

ensuring optimal system performance. When Auto Tuning is enabled, see Section 2.2.2 – Phase Auto Tuning, the

analyzer will auto tune prior to the Cleaning Phase once at midnight. At the end of this phase the flow valve will close.

INFORMATION: Measurements cannot be taken during the Cleaning Phase.

Status Display during CLEANING:

During this phase ‘CLEANING’ will appear in the status display with a countdown timer to indicate the remaining

cleaning time, as shown below.

Figure 13: Cleaning display.

2.3.3.3 – Flow Valve Closing

Analyzers are fitted with flow valves to regulate process water flow through the system. In order to isolate, and hold, a

sample within the chamber the flow valve must close. Valve closing times can vary according to valve type; pneumatic

valves will typically take less than 1 second whereas electrically operated valves can take 15 - 20 seconds. Once the flow

valve has closed the Homogenizing Phase will begin.

INFORMATION: Once either valve has been instructed to open or close it will continue to move to its open or close state – even if the STOP button is pressed.

Status Display during Flow Valve Closing Phase:

‘CLOSING FLOW VALVE’ will appear in the status display to indicate the valve is in motion with a COUNT UP timer.

Figure 14: Valve display.

2.3.3.4 – Phase 3 – Homogenizing

Once the sample is isolated in the chamber, the contents are homogenized to reduce oil particle size into a uniform even

distribution. The homogenization time is configurable, from the ‘Schedule Configuration’ menu, to optimize the

homogenization required for a given oil type.

Status Display during Homogenization:

During this phase the status display will indicate ‘HOMOGENISING’ with a countdown timer for the selected duration as

shown below.

Figure 15: Homogenising display.


Page 19 of 93

OIW-HBO-0002-EX-005



2.3.3.5 – Phase 4 – Settling

A short setting period is required after homogenisation has finished allowing any gases to dissipate and create a more

stable suspension in the sample chamber. This setting period is also configurable, from the ‘Schedule Configuration’

menu, to optimize the settling time for the given oil type.

Status Display during Settling:

During this phase ‘SETTLING’ will appear in the status display with a countdown timer to indicate the remaining settling

time, as shown below.

Figure 16: Settling display.

2.3.3.6 – Phase 5 – Measuring (Scheduled Measurement)

The duration of a scheduled measurement phase is user configurable. At scheduled intervals an isolated sample is

homogenised, evenly distributing the oil droplets for a more accurate reading.

INFORMATION: Measurements cannot be taken during the Cleaning Phase.

Status Display during Measuring:

During this phase ‘MEASURING’ will appear in the status display with a countdown timer to indicate the remaining

measurement time, as shown below:

Figure 17: Measuring display.

At the end of this phase the calculated average measured value is displayed in blue text for 3 seconds.


Page 20 of 93

OIW-HBO-0002-EX-005



2.3.4 – Phase Auto Tuning

Phase Auto Tuning is a process that automatically adjusts the frequency of the ultrasonic system to optimize

performance of the ultrasonic power supply. If Auto Tuning is ENABLED (by an Authorized AS Engineer) then the

optimal ultrasonic frequency will be identified in this stepwise tuning process.

Figure 18: Auto tune menu indicating ‘Enabled Auto Tuning’ function.

When enabled Phase Auto Tuning will occur at the same point prior to the cleaning and homogenization phases in the

cycle but not for every cycle. Auto Tuning will commence in the following circumstances:

When auto tuning is first turned on (by an authorized AS Engineer);

When the measurement cycle is started;

The first Auto Tune Phase after 24:00 hrs;

With temperature changes of ± 5oC (± 41 oF)

When the user presses the SYSTEM TEST button.

Status Display during Auto Tuning Phase:

During this phase ‘AUTO TUNING’ will appear in the status display with a COUNT UP timer to indicate the time taken to

complete the auto tune sequence, rather than counting down the time.

Figure 19: Auto tuning display.

The frequency tuning time will vary based on the frequency range to be swept and the size of the frequency steps taken

– therefore the tuning time is not configurable.

INFORMATION: A comprehensive software overview is covered in Section 3 of this manual.

SECTION 3 - OVERVIEW OF SOFTWARE OPERATION

3.1 – THE OIW-EX SERIES BASIC OPERATING FUNCTIONS The OIW-EX Series of analyzers runs on a standard MS Windows user Operating System (OS). This manual assumes that

the user has a basic competence in using MS Windows OS. In everyday use the system requires minimal access to MS

Windows as it is primarily used to gain access to the data logs stored on the hard drive.

INFORMATION: This Operation Manual provides operational instructions for basic users only. Advanced functionality will therefore be restricted to authorized personnel only.

3.1.1 – Starting the OIW-EX Series

Once installation is complete the system is ready to be turned on. The power up sequence takes approximately 3

minutes. During this time a variety of system level message are displayed on the screen – no user action is required.

The Windows OS starting message will appear followed by the Advanced Sensors OIW-SA software start-up window as

shown below:

Figure 21: OIW Software initialisation message

When the OIW software starts it will automatically detect the hardware configuration and will indicate the model type in

the title bar of the window, as shown below:

Title bar for the OIW-EX-100

Figure 22: Title bar for the OIW-EX-1000


Page 23 of 93

OIW-HBO-0002-EX-005



3.1.2 – MS Windows Functions of the OIW Software

The OIW-EX software retains some familiar functions associated with MS Windows. The ‘title bar’ (horizontal bar across

the top of a window) is equipped with the same buttons and corresponding functionality as all MS Windows

applications, as shown in the table below:

Button: Function:

Minimise the current window.

Reduce the current window size.

Maximise the current window.

Close or exit the current window.

At start up the software opens in full screen mode although during the routine power up sequence some screens will

appear rotated by 90o. Routine operation can only be performed with the software in full screen mode however the

window can be minimised when additional tasks, such as backing up data log files, are performed. The software will

continue routine operation when in the minimised state.

Once the measurement cycle has been started the Windows buttons are hidden to prevent accidentally minimising or

exiting the software. The top figure (a.) below shows when the cycle is stopped the buttons are present. The lower

figure (b.) shows when the cycle is running the buttons are no longer visible.

Cycle stopped-buttons visible

Cycle running-buttons hidden

CAUTION: During routine operation no general requirement exists to exit the software, except during routine maintenance by authorised personal.

b.

Page 24 of 93

OIW-HBO-0002-EX-005



3.1.3 – Starting and Stopping the Measurement Cycle

At power up the green and white ‘Start’ button, shown below, will appear in the bottom right corner of the

‘Configuration Options’ Display area. System start / stop functions are accessible to all users and no login required.

Once the ‘Start’ button has been pressed, the system measurement cycle will begin and the button then changes to a

red and white ‘Stop’ button, shown below.

Conversely, selecting the ‘Stop’ button will end the current measurement cycle and the system will return to the idle

state and indicate ‘Cycle Stopped’ in the ‘Feedback Display’ area.

NOTE: During routine operation the status display text will be BLACK, however when the system has been manually stopped the text will flash red and white alternately.

3.1.4 - Exiting the OIW Software

Exiting the software is password protected to avoid accidental and/or unauthorised shutdown of the analyzer.

To exit the OIW software, stop the measurement cycle, the Windows buttons will reappear, and click the . A warning

box will open on screen, as shown below, prompting the user to enter an administrator password and confirm the

shutdown.

Figure 23: Exit confirmation prompt

Exiting the software, as described above, is a logged event to ensure user traceability therefore a system log is

generated for every shutdown event. Entering a correct password will generate a successful, or normal, shutdown log.

Entering an incorrect password 3 times will generate a system log alarm to indicate, and highlight, a failed exit attempt.

Additional information about ‘System Logs’ can be found in Section 3.2.1.5 – Alarm Indicators. Additionally the OIW

analyzer has been designed to withstand an immediate shutdown, i.e. power failure or emergency shutdown; restart

options are detailed in Section 3.2.3.1.1 - System Settings.

CAUTION: During routine operation no general requirement exists to exit the software, except during routine maintenance by authorised personal. Should the analyzer become damaged or any problems with routine operation arise, power down the system at the main power isolation point and contact Advanced Sensors Ltd or authorized Agent immediately.

3.2.1 – Upper Panel: Feedback Display

The Feedback Display provides the user with system information. The function of this area is to clearly and simply

display the measurement reading, system status and alarm indicators for users. The following section will outline the

purpose and functional information of each component making up this display area. Figure 27 below denotes each

component covered in this section.

Figure 27: Feedback Display Area. 1. Measurement Reading, 2. System Status, 3. System Data, 4. Reading Menu 5. Alarm Indicators,

6. Measurement Average 3.2.1.1 – Measurement Reading Area

This blue window displays the measurement reading value. The reading value will normally be displayed as black text

during routine operation. If the measurement value exceeds the upper calibration limit the reading will turn red and

display the fixed value of the upper limit. The numerical display will be to 2 decimal places for readings below 10, to 1

decimal place for readings between 10 and 100 and whole numbers only for readings above 100 to the upper limit.

3.2.1.2 – Status Display

Below the ‘Measurement Reading’ area, the ‘Status Display’ indicates system information, such as the current

measurement cycle and respective time counter. Cycle phases, as described in Section 2.2 – Overview of Measurement

Cycle, for the EX systems include: Stopped, Valve Opening, Flowing, Cleaning, Valve Closing, Measuring and Auto-Tune.

NOTE: During routine operation the status display text will be BLACK, however when the system has been manually stopped the text will flash RED and WHITE alternately.


Page 29 of 93

OIW-HBO-0002-EX-005



3.2.1.3 – System Information Display

Values displayed in this area are for quick reference and include measurement unit, Flu values, process temperature and

current time. Measurement units, Flu values and current time are fixed values and not configurable. Temperature units

can be configured as described below.

NOTE: To change any of the configurable options, or display options, user login is required. For any changes to take effect the user must log out. For some changes to take effect restarting the software may be required.

Measurement units can only be changed from the Configuration Options panel by an authorized Advanced Sensors

Representative or Engineer. Units are one of the measurement parameters associated with the Oil Type File (calibration

file) for a given oil type.

The temperature can be displayed in units of degrees Centigrade (oC) or degrees Fahrenheit (oF) and can be changed

from the General Configuration Options panel. From the ‘General’ menu select the ‘System Settings’ tab and under

‘Temperature Units’ select oC or oF.

Fixed values for Flu, process temperature and time are displayed for quick reference purposes only. The system time is

set in accordance with the MS Windows OS. The time is also located in this area to provide accurate time information

when samples are taken.

3.2.1.4 – Reading Menu

Display options for the Feedback Display area are accessed when right clicking within the Measurement Reading area (if

using a mouse) or by selecting the grey menu button beside the measurement alarm as shown in Figure 28 below.

3.2.1.5 – System Logs and Alarm Indicators

Multifunctional log and alarm buttons are located below the ‘System Data’ Display with each button representing an

alarm type. When no logs or alarms are present the buttons are green but when a log and/or alarm is triggered the

corresponding button changes to red. Information can be viewed ‘at a glance’ by scrolling over the log and/or alarm

button and the list will appear temporarily in the upper graphical display area ONLY while the cursor is hovering over the

respective button. Selecting an active button will open the respective list in the graphical display (see Section 3.2.1.4 –

Reading Menu Options to select the upper or lower graphic panel for display) and is exited by clicking the red X. An

example of the highlighted log and alarm buttons, listing and delete dialogue are in Figure 29 below. All system logs

and alarms generated are recorded in the system log file for traceability.

Figure 29: Alarm buttons, listing and delete box*.

*Example for illustration only, actual screen may vary with alarm type. The list displays the status, log, severity and acknowledgment listing for each alarm raised, as below in Figure 30. Each

log is accompanied with a time stamp recording the status - when it was raised and then acknowledged. The complete

time and date is displayed when users hover the mouse over a given time in the ‘Raised’ or ‘Ack’ed’ columns.

Figure 30: Alarm list example.


Page 31 of 93

OIW-HBO-0002-EX-005



The status indicates if a log or alarm is ‘Raised’, ‘Acknowledged (Ack’ed)’ or ‘Cleared’. ‘Raised’ indicates the system has

raised a log or alarm and no action has been taken. An ‘Ack’ed’ status indicates the user has checked or selected the log

or alarm for more information and the status box will change to amber. Finally ‘Cleared’ indicates the user has cleared

the log or alarm and the status box changes to green. To delete a selection or all logs or alarms right click in the alarm

list and a delete dialogue box will open to confirm the action. Figure 31 shows an example list of alarms, with

descriptive logs in each of the 3 status settings, and the ‘Delete’ system logs confirmation dialogue.

Figure 31: Status indicators and delete options for alarms.

The ‘Log’ column displays information about the log or alarm. See Section 4 – System Logs and Troubleshooting for

additional information.

Next is a ‘Severity’ column, which categorizes logs or alarms into ‘Info’, ‘Minor’, ‘Major’ and ‘Critical’. Information logs,

‘Info’, indicate a log for information only and the alarm button will remain green with ‘Unread Logs’. For alarm logs that

are categorized as ‘Minor’, ‘Major’ or ‘Critical’ the alarm button will change to red. See Section 4.1 – List of System Log

Messages and User Actions for further information.

The OIW-EX series generates three types of alarms:

1. Measurement Alarms: where specified measurement thresholds are exceeded;

2. System Logs: generated as a result of system events during routine operation; and

3. WS (Water Status) Alarms2: alert the user to any spectrometry readings that fall out of the configured range.

To configure both measurement alarms and system logs see Section 3.2.3.3 – Alarms Configuration Menu. WS alarms

are configured under the ‘Oil Type’ menu as described in Section 3.2.3.5.5. – Spec Mask Settings.

3.2.1.6 – Measurement Average Display

This section of the Feedback Display Area is an optional display to provide the user with a comparative daily average. A

cumulative daily average is calculated for the current (today) and previous (yesterday) days, displayed as in Figure 32

below. Additional information to add or remove this from the display area is in Section 3.2.1.4 – Reading Menu.

3.2.2 – Middle (and Lower) Panel: Graphical Display

The EX Series software has 2 graphical display areas for measurements: the main upper (in the middle display panel)

and a secondary lower (in the bottom display panel). Available configurations vary with model and are described below.

NOTE: When using a keyboard F2 and F3 keys can be used to toggle between displayed graph types, where F2 applies to the middle panel (upper) graph and F3 applies to the lower panel. Additionally F5, F6 and F7 will open PPM, Logs and WS alarm lists respectively in the upper graphical display.

For EX-100 Models:

Display options for the upper and lower graphical display are accessed when right clicking within the graph area (if

using a mouse) or by selecting the grey menu button below the graph as shown in Figure 33 below. The ‘Graph Menu’

options for the EX-100 allow the user to set values for the reading scale, time intervals, track measurement history

and/or set reference guide lines at specified reading values.

The reading scale for a given value range is selected from the drop down menu (dependent on measurement unit).

The time scale can display values for intervals of 9 minutes, 1.5 hours, 6 hours or 24 hours. Time scale values can be set

independently for the upper and lower graphs; meaning each can display measurements for 2 different time intervals.

Selecting the ‘History’ option will display the previous results, for the same time interval, as a watermark line.

Ticking the Guides box will open two scroll boxes for the user to define the values for upper and lower guide lines to

display on the graph for reference.

OIW-HBO-0002-EX-005



For EX-1000 Models:

Both graphical displays for the EX-1000 have the same basic ‘Graph Menu’ functions as the EX-100. Both graphs,

however, have an additional drop down list which allows the user to select a ‘Reading Graph’ and/or a ‘Spec Graph’ to

display reading values or spectral data respectively. Figure 34 below is a graphical display showing a ‘Reading Graph’ in

the upper graphical display and a ‘Spec Graph’ in the lower display. These displays can show either reading or spectral

data or both depending on the users requirements.

Figure 34: Graphical display for the EX-1000*.

*Example for illustration only actual screen may vary with alarm type.

When the ‘Spec Graph’ is selected for display, graph information is displayed to the right which includes the time and

date of the displayed sample, the active oil type, spectra scaled to mask, a ‘Take Spectra’ button and a grey menu

button, like those from previous displays, to bring up the ‘Spectra Graph Menu’.

Selecting the ‘Take Spectra’ button will display a spectral graph of the current active water line. The time, date and

active oil type for the spectra taken is then displayed.

3.2.3.1.1.2 – Water Line Options

The ‘Water line’ refers simply to the process line currently being analyzed. The OIW analyzer has the capacity to analyze

multiple process water lines; in this case each ‘Water Line’ will be numbered and have unique configuration settings

optimized for the oil type being analyzed.

From the Water Line Options menu users can configure averaging time, valve status and trending for a given waterline.

Multiple waterlines, if present, can also be adjusted individually.

The measurement reading by default is not averaged and is normally displayed second by second. From this menu, in

Figure 44, the user can adjust the averaging display time, in seconds, for reading measurements. This will avoid the

appearance of continual fluctuations in the measurement reading display.

Figure 44: Water Line Options menu.

NOTE: Averaging only affects the reading on screen and on the 4-20 mA line, but does not affect the reading sent to the data log file and does not alter the Flu reading on the system display area or within the file.

Flow valves are typically fitted as standard to control the process water flow through the chamber assembly enabling

sample isolation for analysis. Selecting the ‘Valve Present’ box indicates that a flow valve is in use. If the valve is not in

use (deselecting ‘Valve Present’), users can select to ‘Keep Valve Open’, where an electrical signal is sent to maintain the

valve in an open state. However once the measurement cycle is started the valve will close and proceed as normal.

Trending options for measurement data, when enabled, include a trend line connecting data points on the graphical

display and trend compensation. Figure 45 shows when the ‘Trending Enabled’ box is selected the trend line connecting

each measurement data point is displayed on the graph. Once ‘Trending Enabled’ is selected the trend compensation

option becomes available.

OIW-HBO-0002-EX-005



Figure 45: Trend line on measurement graph when ‘Trending Enabled’ selected. Trend compensation accounts for variations in oil droplet size. A compensation calculation, obtained during a

scheduled measurement, is applied to measurements in the next flowing phase. During a scheduled measurement, in

the ‘Measurement Phase’ of the cycle, readings are taken after a short settling period following ultrasonic

homogenisation. The readings taken during this phase are averaged to display a ‘true’ reading in the sample chamber.

From this reading a corrective factor is calculated then applied to the next flowing phase measurements. To enable this

feature tick ‘Trend Compensation’ from the ‘Graph Menu’ as shown in Figure 46.

Figure 46: Trend compensation enabled with corresponding graphical display.

3.2.3.1.1.3 – Custom Logs

By default the system logs are generated which registers all activity on the system and automatically saves information

as comma separated value file (.csv file) on the hard drive. In addition to this log file, users can also select customized

log files which contain only information of interest, Figure 47 below. Custom log files are disabled by default as they

require additional disk space therefore must be specifically enabled by users. Users must select the ‘Enable Custom Log

Files’ box to enable this feature. Then the user can select to record the configuration data at the start of the file and

choose data options of interest. Custom logs can be saved as 1 file, saved at midnight, or 2 files, saved at midnight and

noon, each day as the user requires. This allows users to open data log files in third party programs that may have a

limit on the number of lines they can handle.

Figure 47: Custom logs menu.

INFORMATION: The number of data options selected will determine the log file size.

3.2.3.1.1.4 – Passwords

A password is required to make any configuration changes to the system and shutdown. Passwords for up to 7 users

can be created in the ‘Passwords’ menu shown below in Figure 48. A password must be a minimum of 4 characters in

length up to 9 characters. Characters can be any combination of letters, numbers or symbols. Two levels of user

access, selected from the drop down list, are available: Standard or Full. Standard access disables the change password

function and prevents editing of the ultrasonic settings and calibration parameters. Full access provides full

administrative and configuration access. Once the password parameters have been entered, select the ‘Save New

Password’ button and the information will be saved for the given user number. Passwords will be set up at

commissioning or by Advanced Sensors Personnel.

Figure 48: Password set up menu.

NOTE: If an incorrect password is entered more than 3 times then a log will be written to the system log file and (if enabled) an alarm will be raised.

3.2.3.1.1.5 – Help

The OIW Help feature can be enabled or disabled by selecting the ‘Show Help’ button in the ‘Help’ menu shown in Figure

49 below (left side image). Using the F10 key will also toggle the ‘Help’ on and off. When the cursor is held over a menu

option as shown in Figure 49 below (right side image) the help feature will provide basic information about available

features.

3.2.3.1.2 – Schedule Configuration Options Menu

A configurable schedule menu enables cycle phases to be configured for set periods of time. Each phase should be

optimized for user requirements to suit the specific process and oil type. The times are set using the up/down arrows

of the numerical lists shown in Figure 50 below. It is recommended that once ‘Cleaning’ and ‘Homogenizing’ have been

optimized for the specific process that these settings will not require adjustment.

Figure 50: Schedule configuration menu.

CAUTION: Adjustments to the ultrasonic system (for cleaning and homogenization) shall only be performed by Advanced Sensors trained or authorized personnel only. Excessive application of power to the ultrasonic system may over time result in etching the measurement window and reduce the expected working life of the transducer.

INFORMATION: ‘Flowing’ & ‘Measuring’ can be set to a maximum of 23 hours 59 minutes and 59 seconds. ‘Cleaning’ and ‘Homogenizing’ cannot be set to exceed 3 minutes and 55 seconds. ‘Settling’ cannot be set to exceed 59 minutes and 59 seconds.

The configured phase times are displayed in the left side panel of the ‘Configurations Display Area’ within the ‘Measure

Cycle’ box shown below in Figure 51.

Figure 51: Measurement Cycle quick reference window in the Configuration Display.

3.2.3.1.3 – Alarms Configuration Menu

INFORMATION: See electrical diagram for alarm hardware configuration.

The following sections provide information about the software configuration of system alarms. Please consult the

analyzer wiring diagram for additional details about the alarm hardware configuration.

Configurable alarms allow the user to set lower and upper measurement threshold alarms, allocate alarm limits to relays

and configure alarm timings. All alarms are recorded in the system logs for complete traceability. The following

sections will provide a functional overview of the Alarm Configuration menus. For additional system log information see

Section 4 – System Logs and Troubleshooting p. 61.

The OIW analyzer has 2 configurable alarm types:

1. Measurement alarms (for the selected unit of measurement) and 2. System alarms.

3.2.3.1.3.1 – Measurement Alarms

INFORMATION: Measurement alarms correspond to the user defined measurement unit. Therefore measurement alarms will be displayed in ppm, ppb, % or mg/l units according to user configuration.

Measurement alarms provide the user with warnings to indicate measurement values have exceeded either the upper or

lower set threshold limits. Figure 53 below of the ‘Measurement Alarms’ menu shows the menu options and the ‘Alarm

Settings’ box in the ‘Configurations Setting’ display area. Measurement alarm configuration options (when enabled or

disabled) are displayed in the ‘Configurations Setting’ display area for quick reference.

Figure 53: Measurement Alarms configuration menu and configuration settings display area.

*Example for illustration only actual screen may vary with alarm type.

The ‘Enable Alarm Threshold 1’ box must be ticked to enable and edit this feature. If a second limit is required then the

‘Enable Alarm Threshold 2’ box can be selected (note: ‘Enable Alarm Threshold 1’ must be enabled first before the second

alarm threshold can be selected). Limits are set using the numerical up / down arrows in the threshold box and

displayed in the ‘Configurations Setting’ display area as shown above in Figure 53. Relays can be allocated to trigger

when alarm threshold 1 is crossed. The user can select a relay, all or none from the drop down list at the bottom of the

menu. The dry contact relay can, for example, activate an audible alarm in the control room, open/close a valve to

reroute the process flow or any other user requirement (set up at the time of installation) to indicate an alarm status.


Page 46 of 93

OIW-HBO-0002-EX-005



If an alarm threshold is crossed the user can configure a time limit, ‘Alarm Persistence’, before an alarm is raised to

compensate for temporary out of threshold variations in measurement values. The measured value must then exceed

the thresholds for the specified time before an alarm is raised. In Figure 53 , the ‘Alarm Persistence’ time is selected

using the numerical up / down arrows, to a maximum time of 120 seconds. The selected persistence time is then

displayed in the ‘Configurations Setting’ display area as shown in Figure 53 on page 45. A pending alarm message, in

yellow, will be displayed on screen, as well as the alarm panel, during the persistence period until the time is exceeded

when an alarm is issued, shown in Figure 54. Otherwise if the measurement returns to within the threshold range

during the persistence time no alarm is issued.

Figure 54: Alarm pending warning with the alarm panel open.

An alarm clearing feature can be configured if required. The ‘Clearing Persistence’ time is the length of time an alarm is

active before being automatically cleared. Select the ‘Enable Alarm Clearing’ box to enable this feature and set the

‘Lower Alarm Clearing Threshold’ using the numerical up / down arrows (Figure 55 below). This clearing feature occurs

at user configured time intervals, or the ‘Clearing Persistence’ time, selected using the numerical up / down arrows, to a

maximum time of 23 hours and 59 seconds.

Figure 55: Enable alarm clearing.

CAUTION: Enable ‘Alarm Clearing’ with caution. When ‘Alarm Clearing’ is enabled alarms may clear without alerting the user.


Page 47 of 93

OIW-HBO-0002-EX-005



3.2.3.1.3.2 – System Alarm Settings

System alarms provide the user with warnings or information regarding system activity, errors or faults. From the

‘System Alarms’ menu the user can assign valve open/close timings to trigger an alarm; a specific relay, all relays or no

relay to trigger when system log alarms are raised and/or when the system cycle is stopped. The relay options are

available from a drop down selection menu as shown below in Figure 56. These settings must be applied individually to

each waterline connected to the analyzer. Otherwise settings will only apply to the current waterline listed at the

bottom of the dialogue box.

Figure 56: System alarms menu.

Time delays can be set for the valve; where a time is allowed for the valve to start moving and another for the valve to

complete the motion. If the valve fails to complete the action within the allotted time an alarm log will be raised in

addition to ‘Valve Anomaly’ reported in the status display.

Once a relay is assigned and a system log alarm is raised, the relay output will close. Only when the system log alarm is

cleared will the relay output return to open. If the same relay is assigned to another alarm type, i.e. measurement alarm,

clearing the primary alarm only will open the output; if the system log alarm is secondary, clearing it will not open the

output. Note that ‘Info’ system log alarms are for information only and will not affect the relay output.

The second available relay option will close the relay output when the measurement cycle is stopped and will only open

the relay when the cycle is started again. As above, if this relay is assigned to another alarm type, then the primary

alarm must be cleared for the relay output to open.

OIW-HBO-0002-EX-005



3.2.3.1.4 – Ultrasonics Configuration Menu

NOTE: The information in this section is FOR REFERENCE ONLY. The control and configuration of the ultrasonic unit shall only be undertaken, or supervised, by a trained and authorised Advanced Sensors Ltd Engineer. These settings cannot be accessed by users with Limited or Standard access.

Functions of this menu are view only and can only be modified by an AS authorized Engineer. The following Ultrasonic

menus are for reference only to illustrate menu options, allow the user to view the current ultrasonic configuration and

may be required to assist an Advanced Sensors approved representative with remote diagnosis.

The ‘Ultrasonic Settings’ menu, Figure 57, displays the ‘Cleaning Settings’ for the system. This allows fine-tuning of the

power levels and timings for the ultrasonic’s and should only be configured by authorized Advanced Sensors personnel.

These settings include % power, Pulse Width Modulation (PWM) Period (in ms) and the % PWM Ratio optimized for the

cleaning and homogenizing cycles.

Figure 57: Ultrasonic Settings menu.

The following menu, as shown in Figure 58, lists the optimized cleaning frequencies for set temperature ranges

(increments of 5oC). For every 5oC temperature change the system will automatically adjust the homogenization and

cleaning frequencies to maintain routine operation.

Figure 58: Cleaning temperature auto-tune menu.


Page 49 of 93

OIW-HBO-0002-EX-005



The remaining menu option is ‘Auto Tuning’, Figure 59. Auto tuning, as previously described in Section 2.3.4 — Phase

Auto Tuning, is a process that will automatically sweep through a defined frequency range to detect the optimal

operating and cleaning frequencies for the local temperature. Auto Tuning will always occur at the same point in the

measurement cycle. Auto tuning must be enabled and configured by an authorized Advanced Sensors Engineer or

Representative.

Figure 59: Auto tuning menu.

CAUTION: Adjustments to the ultrasonic system (for cleaning and homogenization) shall only be performed by Advanced Sensors trained or authorized personnel only. Excessive application of power to the ultrasonic system may over time result in etching the measurement window and reduce the expected working life of the transducer.

OIW-HBO-0002-EX-005



3.2.3.1.5 – Oil Type Configuration Menu

The primary measurement of the OIW-EX Series is fluorescence and individual oils will emit a unique fluorescent

characteristic – like a fingerprint. Consequently the OIW-EX system must be calibrated for each type of oil. These

fluorescent characteristics are defined by a series of settings stored on the analyzer hard drive in a calibration folder

with the designation OIWOilTypes. If an oil sample is provided to Advanced Sensors an oil type file can be created and

supplied (electronically or by email) for the given oil which can be stored on the analyzers hard drive in C:\OIWOilTypes;

see Section 5.2 – Accessing Data Log Files on p.71 for additional information. Please contact your local Advanced

Sensors representative for further information.

Each oil type, and in turn each oil type file, is characterised by four main areas of data:

Oil coefficients (fixed values generated by Advanced Sensors Ltd). Temperature coefficients. Gain values (coarse and fine). Offset values.

The following sections will describe the available menu options for EX-100 and EX-1000 systems including instructions

to load an oil type file. At the bottom of each menu will be the ‘Oil Type displayed is’ drop down selection list, ‘Active Oil

Type’ will be displayed, the current waterline (if more than 1 is in use, but typically will display 1) and a close button.

NOTE: The majority of information in this section is FOR REFERENCE ONLY. The control and configuration of oil type settings shall only be undertaken, or supervised, by a trained and authorised Advanced Sensors personnel. These settings cannot be accessed by users with Limited or Standard access.

3.2.3.1.5.1 – Oil Curve

From this menu the user can upload oil type files stored on the analyzer’s hard drive. Multiple oil type files can be

stored on the system, and uploaded, to simplify oil type switching. Oil type files will contain all the calibration

parameters required for the specific oil type being analyzed. The ‘Oil Curve’ menu allows users to load, add or remove oil

type files, displays reference information and the current waterline.

Loading Oil Type Files:

From the ‘Oil Curve’ menu select the ‘Load Oil Type’ button and the Load Oil Type files selection menu will open as

shown below in Figure 60. Select the required Oil Type file from the selection menu followed by the ‘Load’ button to

upload the file.

Figure 60: Load Oil Type files


Page 51 of 93

OIW-HBO-0002-EX-005



Once the required file has been uploaded, the coefficients (Set 1, Set 2, Set 3 or Set 4 as applicable), threshold (if

applicable), out of range value and active oil type are displayed in the ‘Oil Curve’ menu screen as shown below in Figure

61. Select the ‘Close’ button to exit this menu then ‘Save Changes & Logout’ to complete the upload process. For quick

reference the selected file name is displayed at the bottom of each ‘Oil Type Configuration’ menu page and in the ‘Active

Oil Type’ box of the ‘Configurations Setting’ display area for quick reference as shown below in Figure 61.

Figure 61: Oil Curve menu display.

The set of coefficients are data read from the oil type file that relate to the calibration curve.

The threshold value defines the calibration curve limit.

The out of range value defines a measurement value where the oil in water content has exceeded the maximum for the

calibrated measurement range.

Adding Oil Type Files

To enable the analysis of variations in the oil, the OIW system allows users to load additional active oil type calibration

files. Similar to loading oil type files, click on the ‘Add Oil type’ button and the Load Oil Type files selection menu will

open as shown in Figure 62. A list of the available oil type files will be displayed from which the user can select

additional files as required.

Figure 62: Add oil type files.


Page 52 of 93

OIW-HBO-0002-EX-005



Once a file has been selected the respective calibration information will be displayed and a ‘Set as Active’ button is

available, see Figure 63 below, for the user to select the new oil type file to replace the active file currently in use.

Figure 63: Addition of new oil type files.

If not this newly loaded file will still remain available for future selection from the ‘Oil Type displayed is’ drop down list

as shown in Figure 64 below. Selecting a file will display the settings for the selected file, settings will not be applied

until the ‘Set as Active’ button is selected. From this list the user can switch between active oil type files as required for

analysis of different respective oil types.

Figure 64: Displayed oil type drop down menu.

INFORMATION: The ‘Oil Type displayed is’ drop down list, as shown in figure 49, is located at the bottom of each ‘Oil Type Configuration’ menu page. This list enables the user to switch between active oil type files as required for analysis of different respective oil types.


Page 53 of 93

OIW-HBO-0002-EX-005



Removing Oil Type Files

If an oil type file is no longer required for use, or is no longer applicable, it can be removed from the list of loaded oil

types. An oil type file can only be removed once set as active. From the ‘Oil Type displayed is’ drop down menu select

the oil type file to be removed. Select the ‘Set as Active’ button, as in Figure 65 below, noting the ‘Remove Oil Type’

button above it is currently disabled.

Figure 65: Addition of new oil type files.

The ‘Remove Oil Type’ button is only enabled AFTER a file has been set as active as in Figure 66. Selecting this button

will remove the active oil type file from the current list of available files.

Figure 66: Remove Oil Type file.

NOTE: Removing an Oil Type file from the drop down list does not delete it from the OIW system’s hard drive.

OIW-HBO-0002-EX-005



3.2.3.1.5.2 – General Oil Settings

For basic user reference the ‘General Oil Settings’ menu displays only the name, if any, given to the oil type file. This

display name will be for the current active oil type or can display the names of any loaded oil type files from the ‘Oil Type

displayed is’ dropdown list. Figure 67 shows the ‘General Oil Settings’ displayed name for an active oil type and for a

displayed oil type. Additional configurable Oil type functions are available from this menu for trained and authorised

Advanced Sensors personnel.

Figure 67: General Settings menu.


Page 55 of 93

OIW-HBO-0002-EX-005



3.2.3.1.5.3 – Oil Calibration

The ‘Oil Calibration’ menu displays the gain and offset controls for the oil type file. Gain and offset controls are used to

‘fine tune’ the sensor for calibration to ensure an accurate oil type calibration. The Gain and Offset values are not

typically adjusted after a calibration. The Flu value is the fluorescence value for the given calibration.

The values in the display will be for the current active oil type or can display the values of any loaded oil type files from

the ‘Oil Type displayed is’ dropdown list. Figure 68 shows the ‘Oil Calibration’ displayed for an active oil type and for a

displayed oil type.

Figure 68: Oil Calibration menu

OIW-HBO-0002-EX-005



For EX-1000 Systems:

For units equipped with spectrometers, 3 additional menu options are available to configure spectral measurements.

The following section will give a brief overview mainly for information only.

3.2.3.1.5.4 – Spectrometer Settings

The ‘Spectrometer Settings’ menu contains 3 configurable areas: General Settings, Level Trigger Value and Spectrometer

Measurement as shown in Figure 69. The General Settings and Spectrometer Measurement values should be set by an

authorized Advanced Sensors representative.

Figure 69: Spectrometer Settings menu.

The section under ‘General Settings’ displays the Smoothing and Averaging values for the active oil type.

A specific measurement reading, or ‘Level Trigger Value’, can be set by the user to automatically save a spectrometer

reading to file when readings exceed this defined level. This reading will save to the Spec_Logs files stored on the hard

drive of the analyzer.

The detection range, upper and lower detection wavelengths, optimized for the oil type is input into the Spectrometer

Measurement section.


Page 57 of 93

OIW-HBO-0002-EX-005



3.2.3.1.5.5 – Spectrometer Mask Settings

Masking allows a region of interest to be defined for a specific oil type. Selecting the ‘Enable WS Alarm’, as shown in

Figure 70, will generate alarms when the spectral measurements fall outside of the oil type mask ranges. Once this

option is enabled a ‘WS Alarm’ button will appear in the ‘Measurement Reading Display Area’ as shown in Figure 70 (See

Section 3.2.1.5 – Alarm Indicators p.30 and Section 4 – System Logs and Troubleshooting p.61 for more alarm

information). The user can adjust these settings as required to increase the acceptable masking tolerance (as a

percentage ± of the curve), adjust the lower and upper wavelengths and select an above base line percentage.

NOTE: For more information about the Spectrometer Settings & Mask Settings, please refer to the Spectrometer Handbook (OIW-HBO-0005).

SECTION 4 – SYSTEM LOGS AND TROUBLESHOOTING

4.1 – LIST OF SYSTEM LOG MESSAGES AND USER ACTIONS The following section provides a listing, by severity of system log messages that may arise during routine operation of

the analyzer. As previously described alarms and logs are viewed in the middle display area by selecting the alarm / log

button or using the F6 key to toggle between the system logs and graphic display respectively. The Logs Display, shown

in Figure 75, will indicate the alarm status, Log message, Severity and provide a time stamp the log was raised and

acknowledged. Once a system log is raised (1), the corresponding Log message (2) is displayed to inform the user and

that entry is also recorded in the Syslog file. Logs are categorized by ‘Severity (3)’ as Information, Minor, Major or

Critical. Information Logs, as stated, simply convey information to the user with no actions required unless otherwise

stated in the following table; i.e. clearing alarm tables. Minor, Major and Critical Logs are raised to indicate to the user

system issues that require urgent attention which could potentially affect routine operation. Each log is accompanied

by the time it was raised then acknowledged (4 in Figure 75), when hovering the mouse over the time displays the full

time and date of the log.

Figure 75: Sample alarm list where: 1. Alarm Status (Raised, Acknowledged or Cleared), 2. Log message, 3.

Severity Classification and 4. Time the log was raised and acknowledged.

When the list window is full the system prompts users to clear information logs in the first instance. If no information

logs are listed, users are then requested to remove all acknowledged logs. Finally if there are no acknowledged logs, the

system will report the table is full and users should clear the table.

The following table provides users with a list of Log messages (2) sorted by Severity (3) with recommended actions. For

additional information about displaying, clearing and deleting logs see Sections 3.2.1.5 – System Log and Alarm

Indicators p. 30 and 3.2.3.1.3 – Alarms Configuration Menu p. 45.

4.2 – TROUBLESHOOTING Prior to performing any troubleshooting measures, check all sources of power and pipe connections to ensure power and

process water supplies are being maintained to the analyzer.

CAUTION: Ensure that water is in the measurement chamber at all times during the operational cycle. Insufficient water levels may result in damage to the system.

4.2.1 – Calibration Procedure

NOTE: The OIW analyzer is NOT calibrated to a National Standard. The analyzer is calibrated to the laboratory results. Therefore references to calibration refer to the comparison using laboratory results as the standard rather than a National Standard.

Analyzer measurements may not align with the Laboratory results which could be rectified by fine tuning the unit. The

OIW analyzer is fine tuned using laboratory based results as standard. Using specific oil types allows the system to be

calibrated for a unique oil type to provide measurements on site for every second the analyser is operational.

The following section will outline the Advanced Sensors recommended sampling and tuning procedures in addition to

describing gain adjustments to align the readings. Offsets are factory pre-set and shall only be adjusted by Advanced

Sensors trained personnel.

4.2.1.1 – Sampling Procedure

The following points should be observed to ensure samples sent to the Laboratory are consistent with the OIW Analyzer

measurement reading:

Sample extraction from the sample point shall be during the FLOW cycle.

The sample point, when the analyzer is not fitted with one, shall be fitted adjacent to the outlet of the analyzer

within 1 m of the unit.

When sampling for a calibration a minimum of 4-5 samples should be taken over a 12 hour period. Each

sample shall be labelled with the exact time taken (from the analyzer clock), date and location if applicable.

Sampling Steps:

1. Flush the sample point for 20-30 seconds to remove any accumulated debris from the pipe work.

2. Extract the sample over a of 30-60 second period during the FLOW phase of the cycle.

3. Record the measurement reading (averaged over the sample period if possible) along with the START and STOP

times of the sample extraction on the container or in a log. Use the clock on the OIW software for times

allowing the time to be traced in the SysLogs.

4. Once all samples have been taken, obtain the average reading (i.e. ppm) value for the extraction period using

the SamTrack utility software (see the Data Logging Handbook OIW-HBO-0003-EX-002 for additional

information).

NOTE: START and STOP times shall be taken from the OIW Analyzer clock only.


Page 67 of 93

OIW-HBO-0002-EX-005



4.2.1.2 – Calibration Steps:

When all samples for calibration have been analyzed carry out the following:

1. Stop the analyzer cycle.

2. Open the General Configuration menu using the F3 button to toggle through the options. Login with an

Administrator password.

3. Select the ‘System Test’ button and click on the Misc Testing tab. From the ‘Manual Valve Control’ box select

the Open Flow button. Once the valve is open the ‘Open Flow’ button will change to ‘Close Flow’. Close this

dialogue box to continue.

Figure 76: Valve open selection 4. Enable the analyzer to ‘Measure When Stopped’ — from the Oil Type Configuration Menu select the Oil

Calibration tab and select the ‘Measure When Stopped’ option as shown in Figure 77.

Figure 77: Enabling analyzer measurement while stopped to perform calibration.


Page 68 of 93

OIW-HBO-0002-EX-005



5. Turn on the ultrasonic power supply using the ‘Turn US On’ button for 5 – 10 seconds to remove any deposits

from the sample chamber. Turn off the ultrasonic power supply and close the menu to continue.

Figure 78: Ultrasonics On/Off button

6. From the ‘System Test’ menu close the flow valve (see Step 3) to isolate a sample in the chamber.

7. Prior to measurement the sample within the chamber must be homogenized. From the Oil Type

Configuration Menu select the Oil Calibration tab and press the ‘Turn US On’ button as shown in Figure 78:.

After 5 seconds press the ‘Turn US Off’ button to turn the ultrasonic power supply off.

8. Allow the sample to settle for 5 seconds then record the measurement reading.

9. Multiply this reading by the Average Difference (see example results below) value obtained during the

sampling procedure. Record this value.

10. Adjust the Gain using the Gain Control under the Oil Calibration Settings Tab of the main menu until the ppm

reading equals the value obtained in step 10.

11. De-select the Enable Measuring checkbox box in the Measure When Stopped group under the Oil Calibration

Tab of the main menu.

12. Select Save Changes & Logout Button to save.

13. Start the analyzer cycle using Start on main menu.

OIW-HBO-0002-EX-005



4.2.1.3 – Offset and Integration Time Adjustment

Measurement readings inconsistent with laboratory results may be the result of variations in analyzer hardware.

Adjusting the offset and/or integration time will calibrate the hardware and correlate the measurement readings to the

laboratory results. This is a 2 step process which requires both the measurement readings (i.e. PPM values) from the

analyser and the results from the laboratory for graphic comparison.

4.2.1.3.1 – Setting the Offset

If the measurement readings and laboratory results are higher, or lower, by a consistent value as depicted in Figure 79

below then an adjustment to the offset may be required. All adjustments to the offset shall be done by Advanced

Sensors trained and authorised personnel only. If an adjustment to the offset is required please contact Advanced

Sensors for assistance.

Figure 79: Offset Graph

INFORMATION: Adjustments made to the offset not performed by an Advanced Sensors authorized representative may result in misrepresented results.

4.2.1.3.2 – Setting the Gain

Adjustments to the gain allow an increase, or decrease, in the averaging time of a signal. When the measurement

readings and the laboratory results deviate as shown below in Figure 80 then an adjustment to the gain should be

applied.

Figure 80: Gain graph example


Page 70 of 93

OIW-HBO-0002-EX-005



Calculating the correct factor from the laboratory results (as standard) and the measurement readings is described with

the following examples. A correction factor is the calculated as the average difference between the laboratory results

and the analyzer measurement readings. Then this average is used as a multiplication factor to calculate the actual

displayed reading allowing the ‘gain’ settings to be adjusted.

A. If the OIW analyzer is measuring LOWER than the lab

Example Results:

Sample No Lab Reading (ppm) OIW Reading (ppm) (Lab/OIW) 1 3 2 1.50 2 9 4 2.25 3 18 15 1.20 4 27 25 1.08 5 18 14 1.28

Average Difference = 1.46

If the ppm reading = 55

The new adjusted reading should be 55 x 1.46 = 79.7

Now increase the gain to obtain a ppm reading of 79.7. B. If the OIW analyzer is measuring HIGHER than the Lab

Sample No Lab Reading (ppm) OIW Reading (ppm) (Lab/OIW) 1 2 3 0.66 2 4 9 0.44 3 15 18 0.83 4 25 27 0.92 5 14 18 0.77

Average Difference = 0.72

If the ppm reading = 55

The new adjusted reading should be 55 x 0.72 = 39.6

Now decrease the gain to obtain a ppm reading of 39.6

NOTE: If an analysed sample shows a very large difference from all the other samples taken, then this sample should not be included

SECTION 5 – DATA LOGGING

5.1 – INTRODUCTION

INFORMATION: This section describes the data logging features only.

CAUTION: No options should be altered without a full understanding of the change being made.

WARNING: To prevent the risk of injury, the Health and Safety section of this manual and the Installation manual must be read carefully and understood before using this equipment.

This data logging section provides an overview of locating data log files, the log file data and how to view the data

contained in the logs.

The additional Advanced Sensors’ Software described in this section is free to use in conjunction with Advanced Sensors’

Analyzers running Revision 5.0 software and above.

5.2 – ACCESSING DATA LOG FILES Log files are located on the systems hard drive in ‘Shared Documents’ and found in a directory named OIWlogs. Access

to log files may be required for troubleshooting or analytical purposes and can be saved to a USB memory stick.

There are two ways to access the log files for the OIW-EX Series:

1. Direct Access: from the OIW-EX Monitor PC (this will require physical access to the PC within the analyzer for

analyzers NOT fitted with an EX USB port), or

2. Remote Access: from a Desktop/Laptop PC via Ethernet.

5.2.1 – Direct Access

WARNING: Prior to commencing any work on the OIW analyzer, ensure the required ‘hot’ permits have been obtained. The equipment is designed for use in Hazardous Areas therefore shall not be opened without first obtaining the required ‘hot’ permits.

Direct access of data log files requires the user to obtain a ‘hot’ permit as the enclosure door of the analyzer may need

to be opened or, if an EX USB port is fitted, the supplied wired keyboard (non-EX rated) may be used.

When opening the door of the analyzer enclosure loosen off the bolts in the first instance then ensure all the removed

bolts, including IP washers, are stored safely for re-assembly. Note that once all bolts and washers have been removed

that there will be ‘play’ in the door hinges. This is a design feature which allows an even seal along the entire flame-

path. With all bolts removed, open the door fully. The PC is mounted to the door with the spare USB ports on the hinge

facing side. Locate a spare USB port(s) and insert the USB memory stick as shown in Figure 81. If a spare USB port is

not available please contact Advanced Sensors for assistance.

5.3 – OIW LOG FILES - OVERVIEW Log files are structured to distribute all analyzer information and data within discrete folders. Each OIW log file contains

three sub folders, as shown in Figure 85, with additional folders containing specific raw data or information in comma

separated value (.csv) format.

The following sections will describe the layout, content and how to view the data contained within the OIW log file

structure.

Figure 85: OIW log folders: 1. Monthly Data Logs, 2. Oil Type Backups and 3. System Logs

All information and data generated by the analyzer are distributed into Monthly logs, System logs and Oil type backup

files.

1. Monthly Data Logs – these folders contain all data recorded by the analyzer during routine operation. Data is

saved in Monthly folders and displayed in order by year and month.

2. System Logs – contains a complete record of all the analyzer System Logs during operation. Each event, or

system log, is recorded by date and time including the severity and log description.

3. Oil Type Backups – a backup of all parameter information required for each specific oil type used to calibrate

the analyzer. This file may contain information for more than one oil type.


Page 76 of 93

OIW-HBO-0002-EX-005



5.3.1 – Monthly OIW Logs

Each monthly log folder contains the analyzer data for every second the unit is powered on and measuring. Within this

folder will be up to 3 subfolders as shown in Figure 86: Monthly OIW log sub folders; one each for data logs,

spectrometer logs (EX-1000 Models only) and ultrasonic logs.

Figure 86: Monthly OIW log sub folders

1. Data Logs – contains logs of the second by second data acquired during routine operation of the analyzer.

2. Spec Logs – logs of all the spectrometer data, acquired second by second. Note this folder will only be

present for OIW EX-1000 analyzers which are fitted with a spectrometer. Additional spectrometer information

can be found in Section 3.2.3.1.5.4 – Spectrometer Settings or in the Spectrometer Handbook (OIW-HBO-0005-

EX-002)

3. US Logs – contains the Ultrasonic unit power and timing information.


Page 77 of 93

OIW-HBO-0002-EX-005



5.3.1.1 – Data Log Files

Log files are created to capture a comprehensive record of all analyzer activities and cannot be altered. There are 5

circumstances in which a new data log file is created:

1) At start up

2) At midnight

3) At midday (optional – turned off as default);

4) When the configuration is changed and saved;

5) If the system software cannot for any reason write to the current log file a new file will be created to

ensure that no data is lost; e.g. the file has been deleted, moved during a backup or already opened for

viewing in another programme.

*Custom Data Log Files

To accommodate users with specific data requirements, the OIW software enables users to create a secondary ‘custom’

data log. A ‘Custom Data’ log subfolder will be created in the data log file folder, as shown in Figure 87 A. Custom log

files by default are disabled to reduce usage of disk space and therefore require a user to enable only as required. To

enable custom log generation see Section 3.2.3.1.1.3 – Custom Logs.

5.3.1.1.1 – Filename format

Each data log file filename will start with the Serial Number of the unit being logged, followed by the date and time of

file creation, followed by the day of the week (for quick reference) and ending in file type, as shown below in Figure 87.

For example the file ‘’SN00107-04_Dec_13-10_07_45_Wed_OIW_Data’’:

SN00107 is the serial number of the analyzer;

04_Dec_13 the date when the spectra was taken;

10_07_45 the time the log was created;

Wed the day of the week the log was created;

OIW_Data the type of OIW file.

A. B.

OIW-HBO-0002-EX-005



All data logs are stored in Comma Separated Value (.csv) file format allowing for viewing in Notepad, or other simple text

editor. Data logs can also be viewed in tabulated display format when imported into MS Excel, as shown in Figure 88

and Figure 89. As the OIW is run on a standard Microsoft Windows XP or 7 Pro Operating System the user can display

and arrange the files in a variety of ways.

Figure 88: Data Log Files view in Excel and Notepad.


Page 79 of 93

OIW-HBO-0002-EX-005



5.3.1.1.2 – Data File Format and Content

Each data log file is composed of two main data sections – configuration data and measurement data. Each section has

headers to identify the parameter followed by the data values. Figure 89 shows an example of a data log file identifying

section headers and data.

The Configuration header information reflects the current unit configurations. Configurable features of the analyzer

include, but not limited to, data options, custom logs, laser life, system alarms, relays, scheduling, HART, gain and offset

values. The configuration data stored is unique to each analyzer. In the event of a hard drive failure a replacement can

be re-configured quickly from this data, provided the data logs are regularly backed up. Also any changes to the

measurement readings as a result of changes to the systems configuration can be identified from this information.

Figure 89: Typical Log File output in Excel, where 1. Configuration headings 2. Configuration data (parameters) 3. Data headings and 4. Data (actual).


Page 80 of 93

OIW-HBO-0002-EX-005



The Data section of the data file contains all the measurement data and any additional system information. The data

values cannot be amended or changed on the analyzer PC. Data

There are 8 different information columns as follows:

1. Time: time the reading was taken in Hours, Mins and Seconds format;

2. ppm: the PPM value for reading time;

3. ppmC: the compensated PPM value (this column will be blank if trending compensation is not enabled);

4. Raw / Flu: the raw florescence data value from which the PPM value was derived;

5. Temp in C/F: the temperature of the sample chamber in degrees Celsius or Farenheight.

6. AvMea: the AVerage MEAsured value – the average data value. A measurement is taken, displayed and

written to the log file for every second during the flowing phase. At the end of the flowing phase the system

latches the last displayed value – the displayed value is fixed at the last measurement value before the valve

closes. During the measurement phase the measured values are written to the log file but only the averaged

value is displayed on screen.

7. State – indicates the phase of the measurement cycle in which the reading was taken. Phases are abbreviated

to three letters as below:

ABBREVIATION: PHASE: ABBREVIATION: PHASE:

HOM Homogenisation FRE Frequency tuning

SET Settling CLO Valve closing

MEA Measuring OPE Valve opening

FLU Flushing FLO Flowing

HOL Holding CLE Cleaning

8. Comments: the last column(s) will provide additional information as required. Comments can be as follows:

Overall Comments: SW START the software was started START the start button was pressed STOPPED the stop button was pressed

Ultrasonics Related Comments: Fset<frequency> the homogenisation frequency was updated to this value ATEnd Frequency tuning has ended ATAbort Frequency Tuning Abort

Measurement Related Comments3: PPMalm ppm alarm raised PPMack ppm alarm was acknowledged PPMclr ppm alarm was cleared PPMOOR ppm value is out of range

3 The Measurement comment reflects the units of measure for which the OIW Monitors has been configured; i.e. if the OIW Monitor has been configure to measure parts per billion then the comments will be PPBalrm, PPBack, PPBclr and PPBOOR respectfully.

representing the message written.

More than one of the above messages can occur in any one second; in the event of more than 1 comment, each message

will be placed in a separate column.

When Trending is set to ON then every second of data will be logged to the log file. When Trending is set to OFF then

the log file only stores every second of the measurement phase; for all other phases only the start time of that phase is

captured (see Section 3.2.3.1.1.2 – Water Line Options for details on how to turn Trending On or off).

5.3.2 – Oil Type Backup Files

Oil type files contain all the analyzer parameters for a particular oil type, similar to a calibration file. This folder contains

backup copies of all oil type files loaded on the analyzer.


Page 82 of 93

OIW-HBO-0002-EX-005



5.3.3 – System Log Files

INFORMATION: It is strongly recommended that remote Ethernet access is given to Advanced Sensors Ltd so that prompt diagnostics can be performed to minimise downtime.

System log files (referred to as SysLogs) record key events, or system logs, that occur during routine operation of the

analyzer. These log files enable effective troubleshooting and diagnosis of problems should a fault occur.

SysLog files are created under 2 circumstances to ensure that no data is lost:

1. At Start up. 2. If the software is unable to write to the current SysLog file. For example the user has deleted the file, moved

the file during a backup or opened the file to view it during operation while events were being logged.

SysLog files, as shown below in Figure 90, are named as follows: <date of creation>-<time of creation>_SysLog.csv

(note: depending on Microsoft Windows settings the file extension may be hidden).

OIW-HBO-0002-EX-005



5.3.3.1 – System Folder Contents

Problems detected in the routine operation of either the hardware or software will result in a system log which activates

an alarm indicator in Feedback Display (see Section 3.2.1.5 – System Log and Alarm Indicators on p. 30 for display

information). The SysLog files are therefore a record of only these system logs, no other data, which can be viewed in

Excel or Notepad as shown in Figure 91. Unlike the Data Logs, this is a summary file in order to save file size it will not

continually log a recurring alarm during each report log. During normal operation, where the unit is left to run

continuously over a long period of time, the SysLog may span months or even years allowing a long term view of the

operation of the unit.

See Section 4 – System Logs and Troubleshooting on page 61 for addition information.

SECTION 6 – DUAL FLOW SYSTEM

6.1 – DUAL SYSTEM OVERVIEW The OIW EX Side Stream series of analyzers may be fitted with 2 flow valves to facilitate the analysis of 2 different

sources of produced water by a single analyzer unit. The inflow pipe on the chamber assembly is fitted with a ‘T’ piece,

as shown in Figure 92, which connects an additional flow valve for the second process line.

Figure 92: Dual side stream unit with stainless steel enclosure

When an additional flow valve is fitted only one stream at a time can be analyzed. The flow valves are controlled by the

OIW software. The software is configured to open and close each valve in turn as required. Figure 93a shows the

process flows when flow valve 1 is open and then, in figure 93b, when flow valve 2 is open.

Figure 93: Process flows when: a. Valve 1 is open and b. Valve 2 open.

NOTE: Both valves cannot be open at the same time.

OIW-HBO-0002-EX-005



6.2 – SOFTWARE INTERFACE 6.2.1 – Selecting a Water Line for Configuration

When analysis of an additional process line is required, the OIW analyzer can be fitted with a second flow valve. The OIW

software is designed to accommodate this extra process or water line. The second water line must be configured for

the process to be analyzed; this is done in the same way as the first water line. All of the system Configuration Option

Menus will have a Water Line drop down selection box as shown in Figure 94. To apply process specific configurations

users must ensure Water Line 2 is selected for the menu option, configure the items, ‘Close’ and then ‘Save Changes &

Logout’. For complete software information see Section 3 – Overview of Software Operation p.22.

Figure 94: Water line selection from the Configurations Options Menu.

6.2.2 – Display Options for Dual Flow

The main software display maintains the same layout with a few minor adjustments for the second Water Line as shown

below in Figure 95. The following section will highlight the additional information present in the OIW software display

for dual flow systems.

6.2.2.2 – Middle (and Lower) Panel: Graphical Display

The Graphical Displays, like with a single water line, can display multiple options. Each graph can display the

measurement data for each water line individually or both at the same time or a combination of water lines and

measurement readings (for EX-1000 models displays include spectral data). The Graph Menu, #1 in Figure 97 below,

includes a ‘Water Line to Display’ option. Users can select to display water line 1, water line 2 or both on the same

graphical display. Water line 1 will be in RED and water line 2 will be in GREEN. Use F2 to toggle between graphs in the

middle panel and use F3 to toggle the lower panel (or use the drop down arrow as shown in #2 in Figure 97).

APPENDIX 3 – PRODUCT UPDATES (INSERT ANY UPDATES IN THIS SECTION)

A3.1 – VERSION 5.2 RELEASE NOTES A3.1.1 – Visual Changes

While there are no new features added to the V5.2 release there are some feature enhancements and with that, there

will be a new splash screen at the beginning of the software boot up process.

During the initialisation of the system the splash screen will show device detection messages.

A3.1.2 – Feature Enhancements

Upgrade from a previous V5 software release now requires no manual work around. The upgrade will be done

with the use of an installer. This allows seamless upgrade from any previous V5 software release to V5.2.

Due to the technical challenges involved, V4 software should not be upgraded to V5. Customers currently

running V4 software who wish to upgrade to V5.2 will be required to pay for the upgrade and any ASL technical

support required to resolve issues during upgrade. For more information please contact

[email protected]

In some of the previous V5 software releases the boot up process may have been slow and laboured. This

process is now much faster and with the addition of the “Device Detection Dialogue” the user can now see

what pieces of hardware within the system are currently being initialised. This can also aid in fault diagnosis,

as any piece of configured hardware which fails at the point will be highlighted.

A3.1.3 – Issues Addressed

Erroneous log messages created during operation, boot up or upgrade which were misleading and/or incorrect

are now eliminated

In previous V5 releases a dual line system would not trigger a dry contact in a PPM over threshold situation for

Water line 2. Fixed.

In previous V5 releases related to Dual probe systems, both probes would “auto tune” but the frequency

allocated to Probe 1 would be used for both probes during cleaning. Fixed.

In previous V5 releases an independent calibration for each water line on an EX-100 Dual Stream was not

possible. Fixed.

The communication between the software and the spectrometer meant on occasion the system would lose

readings for a short period of time. Fixed.

Some internal code optimisation also carried out.
