7.4 Manual Operation When in Bypass Mode

7.4.1 Source 1 Bypass to Source 2 Bypass

When the transfer switch is set to Source 1 bypass, it can be transferred to Source 2 bypass by the following sequence:

1.Move the generator selector switch to the RUN position.

2.Open the Source 1 bypass switching device. The Source 1 bypass light will no longer be illuminated.

3.Close the Source 2 bypass switching device manually and the Source 2 bypass light will illuminate.

7.4.2 Source 2 Bypass to Source 1 Bypass

When the transfer switch is set to Source 2 bypass, it can be transferred to the Source 1 bypass switching device by the follow- ing sequence:

1.Open the Source 2 bypass switching device and the Source 2 bypass light will no longer be illuminated.

2.Close the Source 1 bypass switching device manually and the Source 1 bypass light will illuminate.

3.Move the generator selector switch to the OFF position.

Section 8: Testing and Problem Solving

8.1 Testing

After transfer switch equipment is initially installed or during planned outages, the installation should be tested to ensure 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 recom- mendations of the generator set manufacturer. Use the test push- button 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.

WARNING

HIGH VOLTAGES ASSOCIATED WITH OPERATIONAL TRANSFER SWITCH EQUIPMENT PRESENT A SHOCK HAZARD THAT CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. USE EXTREME CAUTION TO AVOID TOUCHING ELECTRICAL CONNECTIONS WHENEVER INSPECTING OR TESTING THE EQUIPMENT.

IN ADDITION, IMPROPER OPERATION OF THE GENERATOR SET PRE- SENTS A HAZARD THAT CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. OBSERVE ALL SAFETY PRECAUTIONS IN YOUR GENER- ATOR SET OPERATIONS AND INSTALLATION MANUALS

WARNING

FOR MECHANICAL OPERATIONS, REFER TO SECTION 5. IN THIS INSTRUCTION BOOK. REFER TO THE APPLICABLE LOGIC INSTRUC- TION BOOK FOR ELECTRICAL TESTING

8.2 Problem Solving

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.

A basic problem solving effort is the first step to take prior to call- ing for assistance. Frequently, the effort will successfully address most problems encountered. Most problem solving procedures are outlined in the instruction manual unique to the type of logic being used. In addition, several problem solving procedures are presented here which are specific to the type of switches or switching devices used in this equipment.
