HGM8156 GENSET PARALLEL CONTROLLER USER MANUAL When “Remote Start” (on load) is active or mains is abnormal, “Start Delay” timer is initiated; "Start Delay" countdown will be displayed; After start delay, controller issues start command, and displays "Start Request" countdown;...
HGM8156 GENSET PARALLEL CONTROLLER USER MANUAL b) if mains is closed, controller will soft transfer load to mains; when load transfer is over, bus open relay outputs; Controller issues stop command and enters standby mode. If gensets are in auto mode, they will enter auto stop process, for which please refer to controller user manual.
HGM8156 GENSET PARALLEL CONTROLLER USER MANUAL MULTI-CHANNEL MAINS OPERATION In multi-channel mains system, multiple gensets are controlled by HGM8156 and they supply multiple load. If something abnormal occurs for one mains channel, controller will control genset to start and take load.
HGM8156 GENSET PARALLEL CONTROLLER USER MANUAL PROTECTIONS 6.1 WARNING ALARMS When controller detects warning signals, it only issues warnings, not shutdown the genset. Table 8 Warning Alarms Type Description When the controller detects that start battery voltage has exceeded the Battery Over Volt pre-set value, it will initiate a warning alarm.
HGM8156 GENSET PARALLEL CONTROLLER USER MANUAL 6.2 SHUTDOWN ALARMS When controller detects shutdown alarm, it will cutoff bus close signal and issues stop signal immediately. Table 9 Shutdown Alarms Type Description Gen Phase Sequence When the controller detects phase sequence wrong, it will initiate a Wrong shutdown alarm.
HGM8156 GENSET PARALLEL CONTROLLER USER MANUAL 6.4 TRIP ALARM When controller detects trip alarm signal, it immediately disconnects the bus close signal, but genset doesn't stop. Table 11 Trip Alarms Type Description When maintenance countdown is 0 and action is selected to Trip, Maintenance Time Due controller will initiate a trip alarm.
