Description

The unit is designed for continuous operation from the Genset battery voltage (12 or 24 volts DC). It will shut-off its displays in 1 minute if there is no voltage at the AC inputs and if no key is pressed. It will powerup automatically when voltage is applied to either Genset or busbar voltage input or any front panel pushbutton is depressed.
The synchroscope display will illuminate automatically if both Genset and busbar phase voltages are within their programmed limits. Otherwise, the synchroscope will turn off to prevent the display of irrelevant information. The GEN led will turn off if the Genset phase voltage is outside the set limits. It will flash when the Genset phase voltage is within the limits and the synchronization checking is disabled. It turns on steadily when the synchronization checking is enabled. Please check the PROGRAMMING section for limit setting. The BUS led will turn off if the busbar phase voltage is outside the set limits. It will turn on steadily if the busbar phase voltage is within the limits. Please check the PROGRAMMING section for limit setting. The synchronization checking is initiated either manually by depressing the SYNCH pushbutton or with the SYNCHRONIZATION CHECK ENABLE signal input. If the synchronization checking is enabled, the unit will be allowed to close the relay output when the synchronization conditions are met. Otherwise, it will not close the relay even if conditions are met. The SYNCHRONIZATON CHECK ENABLE signal input may be hard-wired to battery negative for the immediate synchronization after Genset runs. However, a programmable pre-synchronization delay (P_08) may be inserted with the programming menu in order to allow the Genset to stabilize (or even to heat up if needed). The synchronization checking is not timed. The unit will continue checking the synchronization until the synchronization conditions are satisfied or the process terminated with the SYNCH key or the SYNCHRONIZATION CHECK ENABLE signal. A closed to open transition on the SYNCHRONIZATION CHECK ENABLE input will cause the SYNCH RELAY to de-energize and the synchronization checking to terminate. The synch checking may also be initiated or terminated manually by depressing the SYNCH pushbutton. Once the SYNCH CHECK relay is energized, further synchronization checking may be enabled or disabled following the value of the program parameter P_09. If the synchronization checking is disabled after closing the SYNCH CHECK relay, the relay output will not de-energize even if the paralleling contactor fails to close. It is the responsibility of the panel builder to use a quickly closing contactor.

Programming

Both High Temperature and Emergency Stop inputs must be connected to Battery negative prior to enter the programming mode.
The program mode is entered by long-pressing the MENU button. Each depression of the MENU button will switch to the next parameter.
Another long press will enable the lamp test mode. Another press on the MENU button will return the display to normal mode.
The below parameters can be set as required:
AC voltage low limit: 70 to 500 VAC (Ph-N)
AC voltage high limit: 70 to 500 VAC (Ph-N)
MPU crank-cut frequency / 4: 0-1000Hz
Nominal frequency: 0=50Hz 1=60Hz
Oil switch type: 0=oil pressure 1=oil level
Fuel relay function: 0=Activate to start 1=activate to stop.
Auxiliary relay function: 0=Alarm, 1=choke,
2=stop, 3=preheat.
Choke timer: 0 to 15 sec.
Number of phases: 0=1ph 1=2ph 2=3ph 3=3ph
