Section 1 – Introduction

1.1 WinGPS Software This software is used to commission a Regulo installation on a Pilot Operated PRV. In addition, all other Technolog GSM Data loggers can be programmed by using WinGPS, allowing diagnostic tools to monitor GSM communications to and from the data logger.

1.2 Regulo Configuration File Format

Regulo is despatched to the customer with the appropriate configuration for use. The normal configuration is for dual pressure and single flow. Pressure ranges: 100mH2O or 200mH2O Flow Pulse Significance: 0.001 - 0.100m3/hr (cum/hr) or 1 - 100 l/s An example configuration file for Regulo is as follows;

R12001CH - Regulo: 100m/200m, Flow (0.001cum), diagnostics

Outlet Pressure 100m Statistical Analysis over defined logging interval Inlet Pressure 200m Pressure sampled at defined logging intervals Flow Pulse Significance 0.001m

3 Counted over logging interval

Diagnostics: Battery Monitored / programmable alarm threshold. Pump Operation Count, configurable timeout Exhaust Valve Operation Count, configurable timeout Inlet Valve Operation Count, configurable timeout

We do not supply configuration files with editable values because this would affect the correct display scaling on the „Regulo Display Panel‟.

Other variants to this will be supplied as requested; Contact [email protected] or your „Local Representative‟

Section 2 – Programming Regulo Using WinGPS

2.1 WinGPS Setup

2.1.1 Run the WinGPS software by double clicking on the appropriate icon.

AT ALL STAGES OF WinGPS Take note that a red banner will occur prompting a user to perform the necessary action before continuing to the next stage. If using WinGPS for the first time, you will need to setup the communication port to connect to the logger. If this is not performed a „Red Alarm Banner‟ will appear at the bottom of the window. In this case, to continue you will need to select a Comm Port for local communications See next screen for guidance.

2.1.3 Setup Communication Port – Tools, Options

Select „Comm Port‟ from the pull down list. All file directories can be set in this section otherwise the browse buttons are necessary to find the required files. Other features can be adjusted such as data presentation, initial / max communications speeds, inactivity timeout period, audible warnings & enable diagnostic tools.

When finished Select OK, the „Status‟, „Port number‟ & „Baud Rate‟, if connected will be displayed at the bottom right of the screen.

2.1.4 Configure Regulo

If Configuration of Regulo is required, Logger, Configure,

Select File from Directory and Open



The Configuration file details are displayed in a window, for the details to be checked;

a. Outlet pressure transducer range

b. Inlet pressure transducer range

c. Pulse significance for the „water meter‟

To be matched with Transducer Ranges Browse, if necessary, to search for other configurations

If the configuration file information is correct then select Configure.

Select the Communicate button to talk to the Regulo.

The Communications button is highlighted when the cursor is place over it Click the mouse button to access the program.



2.2 General

Logger:

Displays the Logger type, Serial Number and Memory size of the logger Recording:

Status: STANDBY / LOGGING

Mode: Can be adjusted, rotating store or store until full, prior to starting Clock

The Logger can be synchronised with the Computer by selecting „Set Clock‟ Notepad

Displays current configuration

The notepad details can be edited Any notepad changes made must be saved otherwise they will not be written back to the logger. Each Data logger should be given a unique PMAC ID ranging from 0001 to 65535

2.3 Channels All channels can be selected individually to display live inputs. If no channels are selected but the Live Input is pressed, all channels, excluding „Pump, Exhaust and Inlet Valves‟ will display their live input readings.

For Outlet and Inlet pressures, the transducer offsets must be zeroed whilst the transducers are not pressurised. To perform this, highlight one channel, select live input, edit value to remove offset. Other channels are not editable from this page.

The Logging „Rate‟ for each channel is a multiple of the „Timebase‟. Consequently, the logging rate for all channels may be adjusted by simply changing the timebase.



2.4 Remote Communications

2.4.1 Send / Receive Settings

Seven options are available to select as shown in the dialog box. Please note that the more options which are selected, the more messages are transmitted. To get started, we initially suggest the „Regulo Default Settings‟ as shown in the Send/Receive settings are used. Minimum wait time default is 120 seconds. For poor network reliability it may be necessary to adjust this figure to 180 seconds.

2.8 Profile Editor

2.8.1 Concept

The Control Profile Editor provides a graphical editing environment for working with pressure control profiles for Regulo, including Modulo. Multiple profiles can be opened and edited within an MDI (Multiple Document Interface) window similar to the way Word, Excel, etc display multiple documents. Profiles can be read directly from a local logger or file for editing and then saved back to the logger or a file.

2.8.2 Profiles Flow Flow verse Pressure relationship. Pressures are defined for each of 256 bands of flow. The size of each

flow band varies: small bands at low flows increasing to large bands at high flows. The active part of the profile, where the pressure transitions from low to high, is normally located in a small number of bands approximately 2/3 of the way into the profile.

Profile size (in bytes) = 256 Daily Time verse Pressure relationship over 24 hours, with changes of pressure at an Interval specified in

minutes or hours (1 min – 2 hours). Profile size (in bytes) = 1440 / Interval x 2 (two profiles) Weekly Time verse Pressure relationship over 7 days, with changes of pressure at an Interval specified in

minutes or hours (1 min – 2 hours). Profile size (in bytes) = 10080 / Interval

For time profiles (Daily or Weekly) the Interval determines the size of the profile and whether it is compatible with certain loggers and their configurations (see below).

The Interval normally remains fixed but a tool is available (Tools > Change Interval) to change a

profile‟s Interval if required. Modulo supports 1 Flow and 2 Daily profiles, with Intervals in the range 6 mins – 2 hours.

Regulo supports 1 Flow and either 2 Daily profiles or 1 Weekly profile, with Intervals in the range 1 min to 2 hours. Regulo needs to be specially configured for Weekly profiles with intervals <20 minutes, or Daily profiles with intervals <6 minutes.

2.8.3 Starting the Editor The Editor may be started from within WinGPS using either the Tools>Edit Control Profile menu item, or the Edit Profile button on the Pressure Control Tab. The main WinGPS window remains available for interaction with a logger

while the Editor window is open. By default the editor will present a blank window where new profiles can be created or old ones opened. If the editor is started while WinGPS is communicating with a logger then the currently active profile held in the logger (Flow, Daily 1, Daily 2 or Weekly) will be automatically read and presented in a profile sub-window. In the case of a Daily 1 or Daily 2 profile being active, both Daily profiles will be read into separate windows. If no profile is active (e.g. Fixed Pressure mode) the user will be prompted to choose which profile(s) to read. If profiles are read automatically then communication with the logger will be disconnected after reading, unless the logger is controlling in which case communication will be maintained so that live markers can be displayed. (See 2.8.4 Graph, Live Outlet Marker). In most cases only the default active profile will be required for editing, but any profiles held in the logger may be read using the File>Read from Logger menu option.

Each profile sub-window may be freely sized, minimised or maximised and it will re-annotate accordingly. The sub-windows can also be selected and arranged using the Windows menu option.



2.8.4 Graph The graph area of a profile window is automatically annotated with time/flow on the horizontal axis and pressure on the vertical axis. Various tools are available (see 7. Tool Bar) to zoom in and out of profile data, move the graph area, and edit the profile. The following lines/markers may be visible on the graph: Profile The current profile being displayed and edited.

Original Profile The profile before editing, or at the last save.

This is enabled by default, except when creating a completely new profile. It is drawn beneath the current profile so will not be visible until changes are made.

May be turned on or off using View > Show Original Profile VMax & VMin Horizontal lines indicating the maximum and minimum PRV pressure as defined in the pressure

control settings for a logger. These lines are enabled by default if they‟re available (when reading profiles directly from a logger or LGR file).

They are for information only and do not restrict the editing of the profile. For profiles read directly from a logger, the Max & Min will change dynamically if the settings are edited in the Pressure Control Tab of WinGPS.

May be turned on or off using View > Show PRV VMax & VMin PMax & PMin Horizontal lines on flow profiles indicating the maximum and minimum pressure values as

defined in Edit > Flow Properties.

These lines are enabled by default. May be turned on or off using View > Show Network PMax & PMin Fmax & Fmin Vertical lines on flow profiles indicating the maximum and minimum flow values as defined in Edit > Flow Properties

These lines are enabled by default if they‟re available: Fmax line shown if Fmax>0, and Fmin line shown if Fmin>0. May be turned on or off using View > Show Network Fmax & Fmin Overlay Data Time verse Pressure data (time profile) or Flow verse Pressure data (flow profile) from loggers

in the network. See Tools > Overlay Data and Tools > Create Profile from Data. May be turned on or off using View > Show Overlay Data

Live Outlet Marker. Shows the live Outlet pressure at the current logger‟s time or flow. For the marker to be visible and updated WinGPS needs to be communicating with a logger that is controlling and the Channels Tab or Pressure Control Tab must be displayed.

May be turned on or off using View > Show Live Outlet

The colours for each line may be changed using the options in the View > Line Colours menu.

2.8.5 Profile Window Status Line The status line at the bottom of a profile window displays the following information: Cursor location Current time/flow & pressure position of the mouse pointer.

Range The full scale pressure range. Clicking on this area will activate Tools > Change Pressure Range

Interval For time profiles - the size of each time step. Clicking on this area will activate Tools > Change Interval

Profile Properties For flow profiles, clicking on this area will activate Edit > Flow Profile Properties



2.8.6 Main Menu Items File New Open new Flow, Daily or Weekly profile window.

Open Open .LGR file containing existing profiles.

When an LGR file is opened a summary of the file (device, site, etc) is presented and a choice of which profiles to open is offered. LGR files can also be dragged-and-dropped in the Profile Editor to open profiles (see 9. Drag and Drop LGR files)

Read from Logger Read profiles from logger.

A dialog window opens which allows the profiles to be chosen from the ones available in the logger. Any profiles that have already been read from the logger and opened in profile windows will be marked as “(already open)”. The currently active profile in the logger will be selected for reading by default unless it is already open.

Close Closes currently selected profile window. If the profile has been changed since it was

last saved then it will be queried for saving. Save Saves currently selected profile back to its original source (file or logger).

Save will be disabled for new profiles (source unknown). Save As Saves currently selected profile to a specified LGR file.

Save To Logger Saves the currently selected profile back to a logger.

A dialog window opens which indicates the progress of comms with the logger and the saving of the profile. If the profile is not compatible with the logger or its configuration, or the save is possible but with restrictions, then a warning message will be displayed. When saving a Daily profile the user may choose to save it as Daily 1 or Daily 2 in the logger.

Export to Configuration File (.CFG)

Exports the currently selected profile to a logger configuration file suitable for a Regulo or Modulo. A title and header information text, including site name and ID if available, are automatically prepared for the file but can be edited by the user prior to saving. Note that it is not possible for a configuration file to automatically place a profile at the correct absolute pressure because this will vary with the individual offset of the logger‟s Outlet transducer. A warning is included in the file‟s header text to explain this and provide a reference pressure level to adjust the profile to after configuration.

Export to Data File (.DAT)

Export the currently selected profile to a logger data file. If this profile data is overlaid with actual recorded data, the places where the logger was unable to achieve control to the profile become apparent (e.g. insufficient Inlet pressure, or PRV backed-off).

Only works for time profiles at present. Exit Exits the editor. Any profiles that have been changed since they were last saved will

be queried for saving before exiting. (Same as File>Close for each profile)



Edit Undo Undo editing operations. The number of possible times to undo is shown in the menu.

e.g. “Undo (4)” to a maximum of 5. Undo will be disabled, if no undo available. Copy Copy the currently selected profile to allow it to be transferred to another profile or a

different section of the same profile. By default the whole profile will be copied. If a range is selected, just the range will be copied. The menu will show what will be copied: “Copy Flow”, “Copy Day”, “Copy Week” or “Copy Range”.

Copy & Paste Do not use the Windows Clipboard so a copied profile is not available outside of the

editor and will be lost when the editor is closed. Paste Pastes a previously copied profile or profile section into the currently selected profile.

The menu will show what is available to paste: “Paste Flow”, “Paste Flow Range”, “Paste Day”, “Paste Week”, or “Paste Time Range”. Paste will be disabled if there is nothing to paste, or if the copied profile is not

compatible with the current profile. By default any copied whole profile (Flow/Daily/Weekly) will be pasted to the whole of the current profile. Pasting a Daily profile onto a Weekly profile will align the profile with the day that the cursor is on. If a range was copied (“Paste Time Range”, “Paste Flow Range”), the range will be pasted from the start of the graph, or the position the cursor is at if using the Paste option in the R-Click Context Menu. If a range is selected prior to pasting, the copied profile will be placed into the selected range, replicating and/or truncating as necessary to fill the range. For example, with a Weekly profile and a Day ready to paste, selecting the whole week as a range and then pasting the Day into it will replicate the day for all days of the week.

Table of Values Opens a separate window with a table of the profile values, either „Flow verse

Pressure‟ or „Time verse Pressure‟. The position in the table that is first presented for editing is either the first value on the graph or the first value in a selected range. Pressure values can edited by selecting the value of interest and then changing the value in the edit box, either by typing, clicking the up/down arrows, or using the mouse scroll wheel. Cursor Up/Down, Page Up/Down, Home and End keys allow the table to be navigated in addition to the normal scroll bar on the right hand side. When a value is changed in the table the row will be highlighted in red and the profile graph will immediately show the new value.

Click the Save button to keep changes, or Cancel to discard.

Change Interval Converts a time profile‟s interval from one value to another if more or less

time resolution is needed. The conversion will inevitably change the shape of the profile to a greater or lesser degree. The compatibility restrictions concerning loggers and configurations will apply with the new Interval.

(See 2.8.2 Profiles). Smoothing..

Change Pressure Range Converts a profile‟s pressure range from one value to another. This may be

used when exchanging transducers (e.g. 200m to 100m), or to convert from one unit to another (e.g. 100m to 9.8Bar). If the different ranges have different units then a conversion factor may be specified to allow conversion between the units.

Window Arrange When there are multiple profile windows this sub-menu provides a quick way

to arrange windows alongside each other (Tile Horizontal and Tile Vertical), or cascade them (Cascade).

Profiles Each profile window has a menu item that can be selected to change focus to that window. The currently selected window is shown with a check mark.



2.8.7 Tool Bar

Resets the graph scaling and annotation to show the complete time/flow range and the complete pressure range.

Expands the pressure axis by a round number step to magnify the data. The maximum expansion is when 1 division = pressure resolution. If the pressure data does not overflow the top or bottom of the graph prior to expansion then the expansion will be around the vertical mid-point of the data, which saves hunting for the data after expansion. Otherwise, expansion will be around the mid-point of the pressure axis.

Compresses the pressure axis by a round number step to reduce the data. The maximum compression is when the pressure axis shows 0 – full scale pressure.

Magnifies the time/flow axis by a round number step to magnify the data. The maximum expansion for time profiles is when 1 division = 1 minute, and for flow profiles it is 1 division = smallest flow band. For time profiles expansion will be around the mid-point of the time axis, and for flow profiles it will be around the mid-point of a region visible on the graph where the pressure changes (normally low to high).

If a range is selected then the graph will be expanded to show the selected range.

Compresses the time/flow axis by a round number step to reduce the data. The maximum compression is when the time/flow axis shows the whole profile.

Selects Drag mode. Cursor changes to a hand.

In this mode the graph can be dragged to change the part of the profile that is displayed. Dragging is achieved by holding down the left mouse button and moving the mouse.

Selects Draw mode. Cursor changes to a pen.

In this mode clicking the left mouse button will change the profile at the mouse pointer position. Holding down the left mouse button and moving the mouse will change all values in the path of the mouse pointer.

Selects Constant Level mode. Cursor changes to Constant Level.

In this mode clicking the left mouse button will change the whole profile to the pressure of the mouse position. Holding down the mouse button allows the profile to be moved up and down.

If a range is selected then only the range will be changed.

Selects Straight Line mode.

In this mode a straight line profile can be drawn between two points. Pressing the left mouse button will pin one end of the line at the mouse pointer position. While the mouse button is held down the pointer will then define the other end of the line and releasing the button will fix the line.

Selects Move Up/Down mode. Cursor changes to Move Up/Down.

The profile may moved up or down by holding down the left mouse button and moving the mouse as required. The offset of the profile relative to the start position is shown next to the cursor. If range is selected then only the range will be moved.



Selects Move Left/Right mode. Cursor changes to Move Left/Right.

The profile may be moved left or right by holding down the left mouse button and moving the mouse as required. The offset of the profile relative to the start position is shown next to the cursor: for time profiles this is “±hour:min”; for flow profiles it is the number of flow bands. In time profile applications, if a logger‟s clock is fixed (e.g. GMT) any demand in a network will shift with Daylight-Saving-Time adjustments (e.g. BST <> GMT). This tool can quickly make a time adjustment to a live profile. Alternatively, a secondary profile (Daily 2) can be prepared by time-shifting a copy of the primary profile (Daily 1) and then pressure control switched between the two. If a flow profile is moved then its shape will be distorted as a consequence of the flow bands varying in size.

Selects Range mode.

In this mode a time or flow range of values can be defined by holding down the left mouse button on the graph and dragging across the graph. The defined range will be highlighted in light blue. A defined range will often be cleared automatically when performing an action on the range, or when changing modes. Clicking on the range button again will also clear a defined range. On a Weekly profile, holding down the Shift key while defining the range will cause whole days to be selected. This is useful for pasting Day profiles to multiple days (e.g. Mon-Fri). When a range is defined the following functions will work on the range: Copy, Paste, Constant Level, Move Up/Down, Magnify Time/Flow, and Table of Values

See Edit > Table of Values

2.8.8 Right-Click menu on graph Right-clicking on the graph produces a menu that contains most of the Toolbar navigation and mode buttons, together with the Copy and Paste items from the main Edit menu.

Using the Paste option on this menu is valuable because it allows the cursor to be accurately placed on the graph

prior to pasting (e.g. Day onto Week, or Range onto a graph). Ctrl+V will allow the same flexibility.

2.8.9 Drag & Drop Logger (LGR) Files Dragging an LGR file from another application (e.g. Windows Explorer) and dropping it into the Profile Editor window will cause the file to be opened as if it had been selected in File > Open.



Section 3

3.1 Typical Pilot Assembly



3.2 Fitting of the Bias Chamber

With reference to the Typical Pilot Assembly Each Bias Chamber „Pancake‟ is specifically manufactured for each type of Pilot.

After correct isolation of the pilot rail, the body plug needs to be removed and the bias chamber fitted, ensuring a watertight seal.

Fitting of the Pilot Bias chamber should be done with the PRV bypassed. However if this is not possible the following steps can be taken with care. This should be carried out by a competent engineer and should be completed quickly and at a time where changes in flow demand are likely to be small.



1. Gather all equipment needed to install the Bias chamber to the PRV. This will be:

• Pressure gauge. • Pilot Bias chamber with supplied fibre washer • Spanners of correct size.

2. Connect the pressure gauge to the Outlet pressure to ensure the pressure can be monitored during the installation of the bias chamber.

3. Slowly close the isolating tap on the top of the Pilot rail to lock off the top cover of the PRV. Monitor the Outlet pressure to ensure it does not change.

4. Close the isolating tap on the Inlet to the Pilot rail.

5. Closed the isolating tap on the Outlet to the Pilot rail.



6. The pilot rail is now isolated and the valve fixed in a locked position. Un-screw and remove the large metal nut on the bottom of the Pilot. Ensure the fibre washer is also removed

7. Carefully screw on the Bias Chamber with the fibre washer. Tighten to hand tight, if necessary use a spanner to tighten it up about 1/8 of a turn just to make it water tight. (DO NOT OVER TIGHTEN).

8. Open the Inlet isolating tap to the Pilot rail.

9. Open the Outlet isolating tap to the Pilot rail.

10. Finally very slowly open the top cover isolating tap. Monitor the outlet pressure all the time and make sure it does not change.

Remove the pressure gauge from the system.



3.3 Flow Input Cable Wiring Details

3.4 Initialising the Display Sequence The Regulo has a magnetically triggered display as part of its standard design. A programmable sequence activated by short touch, steps automatically: Regulo -> Version number. A Fixed sequence activated by long touch, steps manually: Inlet, Outlet and Target -> Flow, Outlet and Target -> Status, Date and Time.
