Effective 5/98

Step 3: Verify that the voltage selection plug is in the

proper position to match the system voltage.

Step 4: Look for any obviously burned components.

Determine the cause and rectify, if possible.
Replace defective components after the cause
is determined.

Step 5: Press the push-to-close button on the normal

switching device. Verify whether or not the
system voltage now appears on the load termi-
nals.

If YES:

Proceed to check logic for problems
in respective logic instruction book.

If NO:

Check all power connections and
the switching mechanism.

8.2.2 TRANSFER SWITCH WILL NOT AUTOMATI-
CALLY TRANSFER TO NORMAL

Step 1: Check for proper line voltage on N1, N2, N3.

Step 2: Is the normal switching device charged?

If YES:

Continue with other procedures.

If NO:

Go through section 8.2.4 first before
continuing.

Step 3: Is the emergency switch OPEN?

If YES:

Proceed to Step 5.

If NO:

Proceed to Step 4.

Step 4: Measure voltage between terminals A9 and A8

on the emergency switching device (shunt trip).
Does the voltage measure 120 VAC ±10 volts?
Record reading.

If YES:

Check shunt trip in emergency switch

If NO:

Check wiring to A9 and A8.

Step 5: Measure voltage between terminals A1 and A2

on the normal switching device (spring release
coil). Does the voltage measure 120 VAC ±
10 volts? Record reading.

If YES:

Check spring release coil in normal
switching device.

If NO:

Check wiring to A1 and A2.

8.2.3 TRANSFER SWITCH WILL NOT AUTOMATI-
CALLY TRANSFER TO EMERGENCY

Step 1: Check for proper line voltage on E1, E2, E3.

Step 2: Is the emergency switching device charged?

If YES:

Continue with other procedures.

If NO:

Go through Section 8.2.4 first before
continuing.

Step 3: Is the normal switching device OPEN?

If YES:

Proceed to Step 5.

If NO:

Proceed to Step 4.

Step 4: Measure voltage between terminals A9 and A8

on the normal switching device (shunt trip).
Does the voltage measure 120 VAC ± 10 volts?

If YES:

Check shunt trip in normal switch

If NO:

Check wiring to A9 and A8.

Step 5: Measure voltage between terminals A1 and A2

on the emergency switching device (spring
release coil). Does the voltage measure 120
VAC ± 10 volts? Record reading.

If YES:

Check spring release coil in emergency
switch.

If NO:

Check wiring to A1 and A2.

8.2.4 TRANSFER SWITCH WILL NOT AUTOMATI-
CALLY RECHARGE SWITCHES

Step 1: Measure the voltage between the terminals A6

and A2 on the switching device that does not
automatically recharge. Does the voltage read
120 VAC ± 10 volts? Record reading.

If YES:

Check electrical operator inside the
switching device.

If NO:

Verify wiring to A6 and A2.

Step 2: If problem persists contact Cutler-Hammer.
