Controls
Other than a Manual Override lever, there are no operator controls because this is an automatic transfer switch. The manual override is to be used only by licensed professionals.
Operation
To select automatic transfer operation, do the following:
1.Set utility service disconnect circuit breaker in transfer switch to “On” position.
2.Set generator disconnect circuit breaker in transfer switch to “On” position.
3.Set generator’s main circuit breaker to its “On” position.
4.Install 15 Amp fuse in control panel on generator.
5A. If generator is equipped with a system ON/OFF switch, set switch to “ON” position.
B.If generator is equipped with a AUTO/OFF switch, set switch to “AUTO” position.
The system will now be in automatic operation mode.
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 circuit breaker to the “On” position.
Utility Fail
The Home Standby Generator system 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
Transfer
Transfer from utility to generator supply occurs after generator 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 pickup level and minimum run time is completed.
Engine Cool Down
Engine will run for 60 seconds after retransfer.
Maintenance
The transfer switch is designed to be maintenance free under normal usage. However, inspection and maintenance checks should be made on a regular basis. Maintenance will consist mainly of keeping the transfer switch clean.
Visual inspections should be done at least once a month. Access to transfer switch must not be obstructed. Keep
3 feet (92 cm) clearance around transfer switch. Check for an accumulation of dirt, moisture and/or corrosion on and around the enclosure, loose parts/hardware, cracks and/or discoloration to insulation, and damaged or discolored components.
Exercise the transfer switch at least once every three months as described in the previous section Testing the Automatic Transfer Switch unless a power outage occurs and Home Generator System has gone through automatic sequence. Allow generator to run for at least 30 minutes.
Contact a licensed electrical professional to inspect and clean the inside of your transfer switch at least once a year.
