How to Change a Setting
1. Prev ent the transfer switch from operating by discon-
nec ting one sourc e first, then the other, as follo w s:
a. If the transfer switch is in the Normal position,
open the emergency source circuit breaker.
Turn the engine starting 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.
Tu rn engine starting control to test or run.Then
open the emergency source circuit 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 rig h t side with your thum b . See Figu r e 4 - 1.
4. Locate the appropr iate adjustm ent potentiom eter or
DIP switc h for the setting that you want to chan g e.
Refer to Table 4-1 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
clockwise to increase the t ime delay or counter-
clockwisetodecreaseit. SeeFigure4-3.
6. Use a bal l - p oin t pen (or similar pointed tool) to sl ide
the switch actuators left or righ t so they match the
ill u str ation next to the setting (l eft = off, right =
on). Rec heck the setting. See Figure 4-4.
7. Install the cover on the controller by hooking it on
the left si de and latching the right side.
8. Reconnect both harness plugs to the controller by
aligning and pressing straight in until latches click.
Close the enclosure door.
9. Cl ose the enclosure door, then restore both sources:
a. If the transfer switch is in the Norm al position
first close the normal source circuit breaker, then
cl ose the emergenc y sourc e circu it breaker.
b. If the transfer switch is in the Emergency
