ADJUSTMENTS (continued)
4 --- 2
Do not make any setting changes
while the controller is energized.

How to Change a Setting

1. Prevent the transfer switch from operating by discon-
necting onesource first, then the other, as follows:
a. If the transferswitch is in the Normal position,
open the emergency source ci rcuit breaker. Turn
the enginestarting control to off. Then open the
normal source circuit breaker.
b. If the transfer switch is in the Emergency
position,open the normal source circuit breaker.
Turnengine starting control to test or run.Then
open the emergency source cir cuit breaker.
2. Disconnect both harness plugs from controller by
squeezing the latches. Do not pull on the wires.
3. Remove cover from the controller by releasing latch
on right sidewith your thumb. See Figure4-1.
4. Locate the appropriate adjustment potentiometeror
DIP switch forthe setting that you want to change.
Refer to Table4-1 and Table 4–2 on page 4-1 and
Figure 4-2, Figure 4–3, Figure 4–4 on page 4–2.
5. Use a small screwdriver to turn the potentiometer
clockwiseto increase the time delay or counterclock-
wise to decrease it. See Figure 4-3.
6. Use a ball-point pen(or similar pointed tool)to slide
the switchactuators left or right so they match the il-
lustrationnext to the setting (left = off, right = on).
Recheck the setting. See Figure 4-4.
7. Install the cover on the controller by hooking it on
the left side and latching the right side.
8. Reconnect both harness plugs to the controller by
aligning and pressing straight in until latches click.
Close the enclosuredoor.
9. Close the enclosure door, then restore both sources:
a. If the transfer switchis in the Normal position
first close the normal source circuit breaker,
thenclose the emergency source circuit breaker.
b. If the transfer switch is in the Emergency
position,close the normal source circuit breaker.
The load will be automaticallyretransferred to
the normal source. Then close the emergency
source circuit breaker.
