Operation

To select automatic transfer operation, do the following:

1A. For models 071018 & 071019, set disconnect switch that sends utility power to transfer switch to “On” position. This switch is probably located in the main breaker panel.

1B. For models 071020 & 071021, set utility breaker in transfer switch “On” position.

2.Set generator main circuit breaker to its “On” position.

3.Install 15 Amp fuse in generator control panel.

4A. If generator is equipped with a system ON/OFF switch, set switch to “On” position.

4B. If generator is equipped with a AUTO/OFF/MANUAL switch, set switch to “AUTO” position.

The system will now be in automatic operation mode.

When the generator is providing power to the transfer switch, the control module is constantly monitoring generator power. If the air conditioner is called to run, and there is sufficient generator power available, the control module 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 available, B-B will close.

Testing the Automatic Transfer Switch

Turn the disconnect switch feeding the transfer switch contactor to the “Off” position. The Automatic Sequence of the system will follow. To go back to utility power, turn the disconnect to the “On” position.

Automatic Sequence

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 fixed at 20 seconds or 50 seconds with removal of jumper on control board (see System Setup).

Transfer

Transfer from utility to generator supply occurs after voltage is above set levels. Minimum engine run time is 5 minutes after transfer.

Utility Pickup

Voltage pickup level is 80 percent of nominal voltage.

Retransfer

Retransfer from generator to utility supply is approximately 10 seconds after utility voltage supply is above utility pickup level and minimum run time is completed.

Engine Cool Down

Engine will run for 60 seconds after retransfer.
