6.2.1  TRANSFER SWITCH APPEARS INOPERATIVE

Step 1: Verify that all plugs and sockets are properly 

interconnected.

Step 2: Verify that the correct system voltage appears

at NORMAL switch.  Measure the voltage at the
breaker lugs.

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: This step is for closed transition only. Refer

to Figure 5-3 for manual operating instructions.
Verify whether or not thesystem voltage now
appears on the load  terminals.

If YES: Proceed to check logic for problems 

in respective logic instruction book.

If NO:

Check all power connections and
the switching mechanism.

Step 5: This step is for open transition only. Press

the push-to-close button on the normal switch-
ing device (Figure 5-2).  Verify whether or not
thesystem voltage now appears on the load  ter-
minals.

If YES: Proceed to check logic for problems 

in respective logic instruction book.

If NO:

Check all power connections and
the switching mechanism.

6.2.2  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 6.2.4 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. 

6.2.3  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 6.2.4 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.
