4.2. BASIC FEATURES

The following chapters describes the basic features for operating the device.

4.2.1. POWER

To power the handset on, batteries must be inserted or an external power supply must be

connected.

Supported battery types are:

AAA Alkaline non-rechargeable.

AAA Rechargeable NiCd or NiMH.

AAA Lithium batteries are not supported.

The handset is turned on by pressing the Power button:

The handset is turned off by holding the Power button for more than 2 seconds in any menu.

4.2.2. POWER SAVING

Because the handset is battery powered, it has some basic power saving features.

The handset will dim backlight after 10 seconds of inactivity. The handset will eventually turn off

completely. During live view the timeout is extended when the communications are active.

A special condition exist when AVR advanced setting data was read. Instead of powering off, the

handset will enter a memory retain mode for 1 hour before turning off.

This is to prevent accidental loss of settings memory while moving to a new AVR.

Average battery life is estimated at 20 hours on-time.

o Empty, there is no avr settings data. (5 min power-off timeout)

o Ready, there is valid avr data. (1 hour power off timeout)

o Modified, modified data in buffer. (1 hour power off timeout)

The connection status.

o Offline, there is no link.

o Idle, there is a link, without active communication. (eg: the AVR is off) or there

are devices active on the CAN bus that are not supported by the AVR Assistant.

o Online, there is active communication with the AVR.

o Error, there is a link error. Refer to Troubleshooting.

4.2.4. RESET

A hard reset can be generated by holding the and for more than 5 seconds.

4.2.5. DISPLAY BRIGHTNESS

In the main menus, the LCD brightness can be adjusted to one of the 5 levels.

Hold or to adjust the brightness level.

5. CONNECTIVITY

Most EMRI products are fitted with a 4 way green connector. This is an EMRI standard CAN High

Speed connector. The AVR Assistant interfaces with EMRI products using the CAN High Speed

interface.

Figure 5 CAN HS connector on LXCOS Figure 6 CAN HS connector on LX449

The CAN1-CAN2 jumper must be linked to ensure a reliable connection with the AVR Assistant.

Most EMRI standard CAN HS outputs are electrically isolated from all other terminals, except in the

AVR Assistant itself. The DC GND used to externally power the AVR Assistant unit is equal to CAN

GND.

An extern power supply (12V DC) must be electrically isolated for use with the AVR Assistant.

EMRI standard CAN HS connectors are not capable of powering the AVR Assistant, unless

otherwise specified.

The AVR Assistant comes with a dedicated 1.8 meter data cable to connect to an EMRI standard

CAN HS connector.

The connector is polarized using arcs on one side of the connector shrouding.

6.1.1. SAFETY

When reading or writing an AVR it is important that the following conditions are met:

The AVR is not regulating.

(eg: the AVR On link is removed or the exciter wires are disconnected)

The AVR is not hardware self-excited. (eg: the exciter wires are removed)

The AVR is powered by either remanence voltage or an external source.

It is possible to put the AVR in a mode not supported by the current application.

This might damage equipment or even cause injury to personnel.

Refer to the user manual of the AVR for details about applicability of AVR advanced settings.

6.1.2. COMPATIBILITY

The AVR Assistant is not capable of determining the AVR type, and AVR Version attached.

The user of the AVR Assistant must ensure the correct version of AVR is selected prior to reading

or writing settings from or to the AVR.

It is not possible to connect multiple AVR units to a single CAN-bus.

All EMRI AVR-units use CAN-bus at a speed of 250 Kilobit per second.

Contact EMRI for more details.

6.1.3. READING ADVANCED SETTINGS

To read settings follow these steps:

1. Choose Select Device.

2. Select the device and the version.

3. Choose Advanced settings.

Screenshot 2 Advanced settings menu

4. Select Read settings.

Depending on the product and version, extra requirements will show.

Such as:

a. AVR Idle.

The AVR On link must be removed.

This is sufficient for LXCOS from V1.2.0.0 and LX449 from V1.5.3.0.

b. MSelect 0.

In older versions, access to advanced settings is only possible by setting MSelect to 0.

This way, when linking opt, no changes are made by the build-in advanced settings

method.

c. OPT linked.

In older versions, access to advanced settings require a physical connection to be

made.

Screenshot 3 Reading data

5. The AVR will be read.

6. Now it is possible to View the settings, or write to clipboard or other product.

The clipboard can be used to temporarily store the settings of an AVR to read and browse

a different AVR. The clipboard is maintained as long as the AVR Assistant is powered on.

6.1.6. WRITING ADVANCED SETTINGS

To write settings follow these steps:

1. The memory status in the status bar must show “ready” or “modified”.

When no settings were read since power-on, the current memory is

invalid and the text shows “Empty”.

2. The connected AVR is of the same type and version as the AVR that

was read before.

3. Select Write settings in the Advanced settings menu.

A warning will be shown.

4. Hold OK.

Depending on the product and version, extra requirements will show.

Such as:

AVR Idle.

The AVR On link must be removed.

This is sufficient for LXCOS from V1.2.0.0 and LX449 from

V1.5.3.0.

MSelect 0.

In older versions, access to advanced settings is only possible by

setting MSelect to 0. This way, when linking opt, no changes are

made.

OPT linked.

In older versions, access to advanced settings require a physical

connection to be made.

The settings will be written.

5. Press Any key to continue when the Power Cycle warning shows.

6. Select Restart AVR or temporarily remove power from the AVR to

activate the new settings.

If the writing cycle of the setting is aborted before finishing, the settings in the AVR will be

corrupted and the AVR must be reset to factory defaults using the procedure described in

the AVR manual.

It is not supported to write settings of a different version to the AVR.

e.g. Transferring from V1.2.2.0 to V1.4.2.0 might result in erroneous behaviour.

6.2. PROCESS VARIABLES

When the AVR is regulating, the AVR Assistant provides a way to display process variables.

Process variables are values and setpoints used in the regulator process. These also include any

active error conditions.

Enter the Process Variables menu, select the applicable device and version, and the following

values will show on screen.

Screenshot 7 Process variables

Move pages using and and return to the menu’s using .

In this mode, the screen will dim in 5 minutes, and the unit will power off, or enter memory retain

mode after 15 minutes.

Viewing process variables severely reduces battery life.

7. SETTINGS

The AVR Assistant has additional features in the settings menu. These settings apply to the AVR

Assistant itself.

7.1.1. ACCESS LEVEL

The AVR Assistant contains 3 authority levels. These are used to allow access to specific settings,

such as AVR calibration values and internal process variables.

The three access levels are:

Level Statusbar code Code

User U 0000

Service S ****

OEM (Manufacturer) O **** Table 6 Access levels

The access level can be changed using the Access Level option in the Settings menu.

Enter the number using the numerical keypad, use shift to change key modes.

Screenshot 8 Access Level

Only use access codes when instructed by EMRI personnel.

7.1.2. FIRMWARE UPGRADE

The AVR Assistant has a bootloader to upgrade firmware. The bootloader process cannot be

aborted without removing the batteries. Specialized tooling is required to utilize the bootloader.

And is therefore protected by OEM code.

7.1.3. KEYPAD TEST

A keypad test feature is added to quickly test the keypad functionality. Hold the C button to exit.
