Switch JP2 Switch When the generator is providing power to the transfer switch, the controller is constantly monitoring generator power. If the air conditioner is called to run, and there is sufficient generator power available, the controller will close contacts “A-A” to air conditioner contactor. Contacts “B-B” will open before contacts A-A close. If loads are too great for generator, contacts A-A and/or B-B will open. When air conditioning is not needed, A-A will open. If enough power is CT1 & CT2 available, B-B will close. Connectors Testing the Automatic Transfer Switch Turn the utility disconnect circuit breaker in the transfer switch, to the “Off” position. The automatic sequence will follow. To go back to utility power, turn the utility disconnect Supervisory circuit breaker to the “On” position. Contacts Utility Fail The Home Standby Generator set senses when utility voltage is below 70 percent of nominal. Engine start sequence is initiated after 6 second time delay. Engine Warm-Up Time delay to allow for engine warm-up before transfer is fixed at 20 seconds or 50 seconds with removal of jumper on control board. Transfer Transfer from utility to generator supply occurs after voltage is above set levels. Minimum engine run time is 5minutes after transfer.
