b. Start the generator. There is a pre-programmed 20 to 25 second delay in the transfer
switch. The delay is designed to allow the generator a brief warm-up period. When
the delay completes its cycle the switch should engage and the AC loads should oper-
ate normally. An audible click should sound as the relay energizes.
c. Shut down the generator. As the generator winds down the switch should disengage
without chatter or cycling. An audible click should sound as the relay de-energizes.
d. Switch oN the AC input power from the Utility/Shore Power Cord (rV). Start the gen-
erator. After the pre-programmed delay, the switch should transfer power automati-
cally from the Utility/Shore Power Cord (rV) to the generator. Listen for the audible
click as the relay is energized. Green LeD 1 will be lighted indicating that the relay has
energized. Shut down the generator and disconnect AC input power from the Utility/
Shore Power Cord (rV).
