6.3 Problem Solving

This section explains basic troubleshooting for Magnum Breaker 

Transfer Switches. A basic problem solving effort is the first step 

to take prior to calling for assistance.  Frequently, the effort will 

successfully address most problems encountered.  The problem 

solving procedure is presented in the following paragraphs as 

observed Problem Symptoms and one or more possible Solution 

Steps.  All of the steps presented may not apply to all transfer 

switches, depending upon the logic.  Remember, only qualified 

individuals familiar with the transfer switch equipment and the 

system in which it is applied should attempt these problem solving 

procedures.

If a problem persists after having completed the problem solving 

procedure, contact an Eaton representative for further assistance.  

When calling for assistance, the following is the minimum informa-

tion required to properly address the need:

1. Shop Order Number (SO#) or General Order Number (GO#) of 

transfer switch, plus related Item Number

2. Catalog and/or Style Number of transfer switch

3. Actual location of transfer switch (type of facility, address, 

etc.)

4. Company name

5. Name and position of individual representing company

6. Basic description of situation as it exists

7. Any results of problem solving steps taken and/or readings 

taken

6.3.1  Transfer switch appears inoperative
Step 1:  

Verify that all plugs and sockets are properly intercon-

nected.

Step 2:  

Verify that the correct system voltage appears at NOR-

MAL switch.  Measure the voltage at the breaker lugs.

Step 3:  

Verify that the voltage selection plug is in the proper posi-

tion to match the system voltage.

Step 4:  

Look for any obviously burned components.  Determine 

the cause and rectify, if possible.  Replace defective com-

ponents 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 terminals.

If YES: Proceed to check logic for problems in respective

 logic instruction book.

If NO:  Check all power connections and the switching

 mechanism.

6.3.2   Transfer Switch Will Not Automatically Transfer To Normal
Step 1:  

Is Option 29 installed?  If so, there would be a pushbutton 

labeled “Manual Transfer to Normal.”

If YES: STOP!  The transfer switch must be

MANUALLY transferred to NORMAL by 

depressing the pushbutton.

If NO:  Proceed to Step 2.

Step 2:  

Is Option 9B installed?  If so, there would be a selector 

switch labeled “Maintenance.”

If YES:  Verify selector switch is in the “Operate” 

position.

If NO:   Proceed to Step 3.

Step 3:  

Are the correct line voltage and frequency available at ter-

minals N1, N2 and N3?  Record the readings.

If YES: Proceed to Step 4.

If NO:  Check NORMAL source

Step 4:  

Is the voltage selector plug in the correct position?

If YES:  Proceed to Step 5.

If NO: Position plug correctly.

Step 5:  

Check the voltage on transformer NT1 by measuring volt-

age between voting relay KV-1 and GND.  Is the voltage 

measured 120 Vac (+/- 10 volts)?  Record the reading.

If YES:  Proceed to Step 6.

If NO:   Check voltage transformer NT1.

WARNING

HAZARDOUS VOLTAGES IN AND AROUND TRANSFER SWITCH 

EQUIPMENT DURING THE PROBLEM SOLVING PROCESS CAN 

CAUSE PERSONAL INJURY AND/OR DEATH. AVOID CONTACT 

WITH ANY VOLTAGE SOURCE WHILE PROBLEM SOLVING.

WARNING

ONLY PROPERLY TRAINED PERSONNEL FAMILIAR WITH THE 

TRANSFER SWITCH EQUIPMENT AND ITS ASSOCIATED EQUIP-

MENT SHOULD BE PERMITTED TO PERFORM THE PROBLEM SOLV-

ING FUNCTION.  IF AN INDIVIDUAL DOES NOT FEEL QUALIFIED TO 

PERFORM THE PROBLEM SOLVING FUNCTION, THE INDIVIDUAL 

SHOULD NOT ATTEMPT TO PERFORM ANY OF THESE PROCE-

DURES.
