Transfer Switch Menu:
Mains Under/Over Voltage Alarm: Loss of Mains
Mains Under/Over Freq. Alarm: Loss of Mains
Load Surge: Loss of Mains*
NOTE
Loss of Mains may be substituted with Loss of Mains w/alarms if alarm
indications during a loss of mains condition are desired.
*Loss of Mains action is instant, and does not use the loss of mains action delay.
All other Loss of Mains detection setpoints use the Loss of Mains action delay
time before activating the generator set start sequence.
Loss of mains action for a single parallel unit is identical to the single no parallel
application. Upon sensing a loss of mains for the loss of mains action delay
period, the EGCP-2 will open the mains breaker, start the generator set, wait for
the gen stable time, and close the generator onto the dead bus, providing the
load with power.
Being a single unit parallel application, upon sensing return of the mains, and
mains stable for the mains stable delay, the EGCP-2 will synchronize the
generator set with the mains. After synchronizing to the mains, the EGCP-2 will
parallel the generator with the mains, and softly unload the generator. Upon
reaching the generator Unload Trip Point, the EGCP-2 will issue a generator
breaker open command. This sequence softly transfers load from the generator
back to the Mains. After the generator is unloaded, and its breaker is opened, it
will shut down. There may be a cooldown period prior to shut down if the
generator set has run at loads which exceed the Cooldown Limit KVA value.
