Step 1: To begin the test, close the normal source circuit breaker. The switch controller will illuminate the Utility Available LED (if equipped) when correct voltage is sensed.
Step 2: Close the Alternate source breaker and start the engine generator.The S2 (Alternate) Available LED will illuminate when correct voltage and frequency levels are sensed.
Step 3: Simulate a utility outage by opening the Source 1 (normal side) breaker.
Step 4: When the time delay is completed the ATS will transfer to Generator. Systems shall transfer in no less than 10 seconds where failure of the equipment to perform could result in loss of human life or serious injuries.
Step 5: Re-close the Source 1 breaker to re transfer to the normal source. The delay to utility timer begins its timing cycle. When the timer has completed its timing cycle, the ATS will transfer.
Step 6: The delay engine stop timer will begin its timing cycle. The generator runs unloaded for the duration of this timing cycle. When the timer completes its timing cycle, the generator will stop.
