Step 4: Manually start the engine generator at the gen-
erator controller. Check that the
Source 2 Available
light is lit (Figure 6). Check all Voltages phase to phase
and phase to neutral.
Note: The transfer switch is equipped with a time
delay feature when in the Neutral position. This fea-
ture provides a delayed transition transfer mode for
an Open Transition Transfer Switch. Often used in
systems with inductive loads, a delayed transition
transfer switch may prevent or reduce excessive
inrush currents due to out of phase switching of
loads. This switch provides a time delay in the
Neutral position during the transfer and re-transfer
operations in which both Source 1 and Source 2 are
disconnected from the load circuit. The time delay
is adjustable and is the same for both transfer and
re-transfer operations. The range is from 3-60 sec-
onds.
Step 5: Move the Selector Switch, on the Device Panel,
to Source 2 (Figure 7). The Transfer Switch will move
to the Neutral Position, delay, and then move to the
Source 2 position. Check the
Source 1 Connected light
and make sure it is extinguished. Check that the
Source 2 Connected light is illuminated. Return the
Selector Switch to Source 1. Make sure the Transfer
Switch returns to
Source 1 and the Source 1 Connected
light illuminates (Figure 6). Shut down the Generator
after the manufacturer’s recommended cool down time.
