Step 10: ATH4/ATV4 Power Failure Test - Initiate a Load Test by simulating an actual power failure.
(1) This should be done by opening the upstream breaker or fused disconnect switch.
(2) If the ATS is Service Equipment Rated with no upstream disconnect, use the Normal Control Circuit Disconnect to simulate a power failure (Figure 10).
This can be found in one of two places. The first would be located directly beside the normal breaker. The second would be located on the transformer panel/customer connection panel. The normal con- trol circuit disconnect is the disconnect marked
Normal.The disconnect switch should be in the ON position for normal operation. Turning the switch to the OFF position will simulate a normal power out- age.
Figure 10 Control Disconnect
(3) The generator should start and the ATS should transfer to Emergency.
(4) After transfer, close the upstream breaker, or close the Normal Control Circuit Disconnect. The TDEN timer should begin counting, and, when com- plete, the ATS should transfer to Normal. The En- gine Cooldown Timer should time out and shut the emergency power unit down.
NOTICE
While performing testing, if an undesired or undoc-umented result occurs, first contact the local
Genset dealer. If the result is not corrected, contact the Cutler-Hammer Product Integrity Center at 1-800-210-6208.
