NOTES: Source 1 Available and Source 1 Position LED’s will illuminate.

If Source 1 Available LED does not illuminate, verify that Source 1 Voltage is above the preset restore value.

The Gen-Set will start and run while

Source 2 stop Delay Timer is timing.

5.Close the External (up-stream) Source 2 line circuit breaker.

6.Start the engine generator in MANUAL mode.

NOTE: When the voltage and frequency reach preset values, the Source 2 Available LED will illuminate.

7.Verify the phase to phase voltages at Source 2 line terminals.

8.Verify that the phase rotation of

Source 2 is the same as the phase rotation of Source 1.

9.Shut down the generator's engine.

(Place in Automatic Mode.)

NOTE: Source 2 Available LED will turn off.

NOTE: The engine generator will continue to run for the duration of Source 2 Stop Delay Timer.

10.Place the disconnect switch to ENABLE.
