• The "engine warm-up timer" will run for about 15
seconds. When this timer finishes timing, board
action will initiate transfer to the "Standby" power
source. As shown in Figure 4 (above), the timer is
still running and transfer has not yet occurred.
• Generator AC output is available to transfer switch
terminal lugs E1/E2 and to the normally open
contacts of a transfer relay. However, the transfer
relay is de-energized and its contacts are open.
