8. Manually move the transfer switch mechanism into the stand
by or generator position. i.e Circuit breaker connected to
generator should be closed.

OPERATIONAL TESTING

1. Turn on fuel supply.
2. Attach fuel pressure gauge to test point on fuel regulator.
3. Replace the fuse in the generator control panel and place the
switch into the manual position which will start the engine.
4. Allow the generator to warm up. Move the generator main
circuit breaker to the ON or CLOSED position. Generator
power is now being supplied to the transfer switch.
5. Check voltage and frequency of generator output at the
transfer switch terminals. Line to Line voltage should be
240V (+/- 10 VAC) and line to neutral voltage should be
approximately120V. Frequency should be 62 – 63Hz. If either
the voltage or frequency are incorrect refer to the owners
manual for instructions on how to adjust.
6. Once the voltage and frequency of the generator output have
been confirmed and are correct move the generator main
output breaker to the OFF or OPEN position and move the
control panel switch to the off position.
7. Manually move the transfer switch mechanism into the utility
position. i.e Circuit breaker connected to 50A utility breaker
should be closed.
8. Move the 2-pole 50A circuit breaker mounted in the main
distribution panel to the ON or CLOSED position. Move
the generator control panel switch to the Auto position. To
indicate that the generator control panel is able to identify the
presence of utility voltage the GREEN system ready light will
be illuminated on the generator control panel. (Disregard the
flashing RED lights at this time.) The engine should NOT start.
Move the generator main output circuit breaker to the ON or
CLOSED position.
9. Move the 2-pole 50A circuit breaker mounted in the main
distribution panel to the OFF or OPEN position. After a short
delay the generator will start. The transfer switch mechanism
should automatically move from the Utility position to the
Stand By position.

10. One by one move each circuit breaker in the load center to
the ON or CLOSED position. Once all the circuit breakers are
closed and the Generator is powering all the priority loads.
Check the fuel pressure at the fuel regulator. When powering
the loads the fuel pressure should NOT be less than:
• Nat Gas Fuel = 5 inches W.C
• LP Vapor Fuel = 10 inches W.C
11. Move the 2-pole 50A circuit breaker mounted in the main
distribution panel to the ON or CLOSED position. The Transfer
Switch mechanism should automatically move to the utility
position. The Generator will continue to run for a pre set cool
down period then will automatically shut down.
12. The operational tests are complete. Refer to the owners
manual for instructions on setting the generator exercise
function.
