3.5GENERATOR TESTS UNDER LOAD

1.Set the generator's main circuit breaker to its OFF or OPEN position.

2.Manually actuate the transfer switch main con- tacts to their STANDBY position.

3.To start the generator, set the Auto/Off/Manual switch to MANUAL. When engine starts, let it sta- bilize for a few minutes.

4.Turn the generator's main circuit breaker to its ON or CLOSED position. The generator now pow- ers all LOAD circuits. Check generator operation under load as follows:

•Turn ON electrical loads to the full rated wattage/amperage capacity of the generator. DO NOT OVERLOAD.

•With maximum rated load applied, check voltage and frequency across transfer switch terminals E1 and E2. Voltage should be greater than 230 volts; frequency should be greater than 58 Hz.

•Let the generator run under rated load for at least 30 minutes. With unit running, listen for unusual noises, vibration, overheating, etc., that might indicate a problem.

5.When checkout under load is complete, set main circuit breaker of the generator to its OFF or OPEN position.

6.Let the generator run at no-load for several min- utes. Then, shut down by setting the Auto/Off/Manual switch to its OFF position.

7.With the manual transfer handle, move the switch's main contacts back to their utility posi- tion, i.e., load connected to utility power supply. Handle and operating lever of transfer switch should be in down position.

8.Turn on the utility power supply to transfer switch, using whatever means provided (such as a utility main line circuit breaker). The utility power source now powers the loads.

9.Set the generator's Auto/Off/Manual switch to its AUTO position. The system is now set for fully automatic operation.
