During this autodetection process the message "Trying to connect" is displayed on screen. This process
takes approx. one minute.
When an incompatible configuration type is found in a detected controller, the message "Unknown cfg format
COM x Addr yy" is displayed on screen for 5 seconds. Detecting continues with the next address in the range.
If detecting finishes with no compatible Master controller found, the message "No connection" is displayed on
screen for 5 seconds. The detecting process starts from the beginning and continues until compatible a
Master controller is found.
Unsupported types of controllers or controllers that are not properly communicating are skipped during the
search.
5.4.6 Connection troubleshooting
There are a few reasons why the Remote display may not connect to the Master controller:
An unsupported type of Master controller connected.
Unsupported firmware in Master controller.
Configuration table error in Master controller.
Wrong settings of setpoint COM x Mode in master controller.
Wrong settings of setpoint COM x Communication Speed in master controller.
Wrong connection, wiring, or communication failure.
5.4.7 Function description
Remote display software works as "remote display and control" for the Master InteliLite 4 family controller.
Gen-set can be controlled using the Remote display and the Master controller simultaneously and
independently. All Remote display screens (Information screens, Measurement screens, Setpoint screens
and History Log) display the same data as the Master controller. The front panel buttons on both controllers
work the same way. All remote display LEDs show the same state as corresponding LEDs on Master
controller. User can switch screens, enter or set password, adjust setpoints, change language, change
Configuration Level, change display contrast and view history records.
Note:
It is recommended to use the same type and model of controller for Master and for Remote display.
Only in such case is assured the proper function of all buttons, LED diodes and display.
Example:
When AMF controller HW type is used as a Master controller and MRS controller HW type is
used for Remote display there is no possibility to control MCB in MAN mode as there is no MCB button on
the MRS controller. Even though all these not recommended combinations may work, all of the limitations
above must be considered.
Master device is always able to function without a connected Remote display. Disconnecting of the serial line
between the Master controller and Remote display has no effect on the Master controller.
When the serial line between the Master controller and Remote display is disconnected, or communication
cannot be established, Remote display shows its own Init screen with the message "Trying to connect" and all
LEDs are off.
Once the Remote display finds compatible Master controller it shows message "Cfg processing" and
downloads configuration table from master controller. After the configuration from Master controller is
downloaded and the Remote display is reinitiated, jump to master controller's Main measurement screen and
regular operation is started.
