SECTION 6: TESTING AND PROBLEM
SOLVING
6.1 TESTING
After transfer switch equipment is initially installed or dur-
ing planned outages, the installation should be tested to
insure that all equipment operates properly. This attention
to detail will help to avoid unexpected malfunctions.
Mechanical and/or electrical tests should be performed.
The frequency of subsequent testing should be based
on recommendations of the generator set manufacturer.
Use the test pushbutton to check the electrical operation
of the switch. IF A TEST SWITCH IS PROVIDED,
ALWAYS RETURN THE SWITCH TO THE AUTO
POSITION AFTER THE TEST IS COMPLETE.
HIGH VOLTAGES ASSOCIATED WITH OPERA-
TIONAL TRANSFER SWITCH EQUIPMENT PRESENT
A SHOCK HAZARD THAT CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. USE EXTREME
CAUTION TO AVOID TOUCHING ELECTRICAL CON-
NECTIONS WHENEVER INSPECTING OR TESTING
THE EQUIPMENT.
IN ADDITION, IMPROPER OPERATION OF THE GEN-
ERATOR SET PRESENTS A HAZARD THAT CAN
CAUSE SEVERE PERSONAL INJURY OR DEATH.
OBSERVE ALL SAFETY PRECAUTIONS IN YOUR
GENERATOR SET OPERATIONS AND INSTALLA-
TION MANUALS.
For mechanical operations, refer to Section 5 in this
instruction book. Refer to the applicable logic instruction
manual for electrical testing. Refer to paragraph 3.4 for
logic instruction manuals.
6.2 PROBLEM SOLVING
HAZARDOUS VOLTAGES IN AND AROUND TRANS-
FER SWITCH EQUIPMENT DURING THE PROBLEM
SOLVING PROCESS CAN CAUSE PERSONAL
INJURY AND/OR DEATH. AVOID CONTACT WITH
ANY VOLTAGE SOURCE WHILE PROBLEM SOLV-
ING.
ONLY PROPERLY TRAINED PERSONNEL FAMILIAR
WITH THE TRANSFER SWITCH EQUIPMENT AND
ITS ASSOCIATED EQUIPMENT SHOULD BE PERMIT-
TED TO PERFORM THE PROBLEM SOLVING FUNC-
TION. IF AN INDIVIDUAL DOES NOT FEEL QUALI-
FIED TO PERFORM THE PROBLEM SOLVING FUNC-
TION, THE INDIVIDUAL SHOULD NOT ATTEMPT TO
PERFORM ANY OF THESE PROCEDURES.
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. Most
problem solving procedures are outlined in the instruc-
tion manual unique to the type of logic being used. In
addition, several problem solving procedures are pre-
sented here which are specific to the type of switches or
circuit breakers used in this equipment.
If a problem persists after having completed the problem
solving procedure, contact a Cutler-Hammer represen-
tative for further assistance. When calling for assis-
tance, the following is the minimum information 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 com-
pany
6. Basic description of situation as it exists
7. Any results of problem solving steps taken and/or
readings taken
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.
