Hold 5 sec. to set 20 min. engine exercise period immediately (engine starts) and weekly thereafter. ➤ blinks slowly when bu...

SECTION 3 TESTING & SERVICE 3 --- 1 PREVENTIVE MAINTENANCE Reasonable care in preventive maintenance will insure high reliability and long life for the automatic transfer switch. Operate the switch at least once a month . Perform this four step Electrical Operation Test. This is a test with load...

TESTING & SERVICE (continued) 3 --- 2 MANUAL LOAD TRANSFER This procedure will manually transfer the load if the controller is disconnected. Do not manually operate the transfer switch until both power sources are disconnected: open both circuit breakers. 1. Open normal and emergency source circ...

SECTION 4 ADJUSTMENTS 4 --- 1 Time Delay Adjustment Standard time delays are set to customer specifications(if none specified, standard factory settings are used). To change a setting, follow procedure on page 4-2. UseTable 4-1 as a guide to time delay values and their corre-sponding adjustment DIP ...

ADJUSTMENTS (continued) 4 --- 2 Do not make any setting changes while the controller is energized. How to Change a Setting 1. Prevent the transfer switch from operating by discon- necting one source first, then the other, as follows: a. If the transfer switch is in the Normal position,open the emerg...

SECTION 5 CONTROL FEATURES – ENGINE EXERCISERS 5 --- 1 These timers periodically exercise the emergency engine-generator plant. They can be set to exercise with or withoutload transfer, or they can be completely disabled. The engine-generator should be exercised under load once a week for aminimum t...
