Standard controls and indicators. 3 – Electrical Operation This procedure will check the electrical operation of the Automatic Transfer Switching Equipment. Close the automatic transfer switching equipment enclosure doo...

Hold 15 sec. to start the engine generator and to transfer the load to emergency. Press to cancel the active exercise period (stops engine now or after cooldown) See page 5–1. Hold 5 sec. to set 20 min. engine exercise period immediately (engine starts) and weekly thereafter. ³ 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 tr...

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 switching device until both power sources are disconnected: open both circuit breakers. 1. Open normal and emergency sour...

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 swi...

ADJUSTMENTS (continued) 4--2 NOTICE Do not make any setting changes while the controller is energized. How to Change a Setting 1. Prevent the transfer switching device from operat- ing by disconnecting one source first, then theother, as follows: a. If the transfer switching device is in the Normalp...

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 fora minimum time...

CONTROL FEATURES (continued) 5--2 OPTIONAL PROGRAMMABLE ENGINE EXERCISER (Accessory 11CD) The optional programmable engine exerciser providesseven days of different exercise periods. The timer isconnected and mounted below the controller. Apermanent backup battery maintains the setting; whenpower is...
