Operation
Normal Operation
Utility Fail
The generator senses when the utility voltage is below
70 percent of nominal. The engine start sequence initiates
after a 6-second time delay.
Engine Warm-Up
This is the time delay for engine warm-up before transfer.
Transfer
The transfer from the utility to the generator supply occurs
after the voltage is above set levels. The generator control
board will send a transfer signal (12 VDC) to the TRCM
board. Then, the red LED will turn ON and the transfer switch
switches to generator power. The minimum engine operation
time is 5 minutes after transfer.
Utility Pickup
The voltage pickup level is 80 percent of the nominal voltage.
Re-transfer
Re-transfer from the generator to the utility power is
approximately 10 seconds after the utility voltage supply
is above pickup level and the minimum operation time is
completed.
Engine Cool Down
Standard controller - The engine will operate for 1 minute (60
seconds) after re-transfer.
GC1031 controller - The engine will operate for 5 minutes
(300 seconds) after re-transfer.
