Control Panel/Start-Up/Testing
verify wiring from generator to E1, E2 and Neutral
lugs at transfer switch.
12. Set the generator main circuit breaker to OFF or
OPEN.
13. Push the generator OFF button. The engine should
shut down.
NOTE: It is important not to proceed until certain that
generator AC voltage and frequency are correct and
within the stated limits.

Generator Tests Under Load

To test the generator set with electrical loads applied,
proceed as follows:
1. Verify that the generator is OFF.
2. Turn OFF all breakers/electrical loads that will be
powered by the generator.
3. Turn OFF the utility power supply to the transfer
switch, using the means provided (such as a utility
main line circuit breaker).
DANGER
Electrocution. Do not manually transfer under load.
Disconnect transfer switch from all power sources
prior to manual transfer. Failure to do so will result
in death or serious injury, and equipment damage.
4. Manually set the transfer switch to the STANDBY
position, i.e., load terminals connected to the
generator's E1/E2 terminals. The transfer switch
operating lever should be down.
5. Push the generator MANUAL button. The engine
should crank and start immediately.
6. Let the engine stabilize and warm up for a few
minutes.
7. Set the generator main circuit breaker to ON or
CLOSED. Loads are now powered by the standby
generator.
8. Turn ON the circuit breaker/electrical loads that are
powered by the generator one by one.
9. Connect a calibrated AC voltmeter and a frequency
meter across terminal lugs E1 and E2. Voltage
should be approximately 220/230/240 volts and frequency should be 50 Hz. If the voltage and
frequency are rapidly dropping as the loads are
applied, the generator may be overloading or there
may be a fuel issue. Check amperage value of
loads and/or fuel pressure.
10. Let the generator run at full rated load for 20-30
minutes. Listen for unusual noises, vibration or
other indications of abnormal operation. Check for
oil leaks, evidence of overheating, etc.
11. Verify gas pressure while under full load.

12. When testing under load is complete, turn OFF
electrical loads.
13. Set the generator main circuit breaker to OFF or
OPEN.
14. Let the engine run at no-load for 2-5 minutes.
15. Push the generator OFF button. The engine should
shut down.

Checking Automatic Operation

To check the system for proper automatic operation,
proceed as follows:
1. Verify that the generator is OFF.
2. Install front cover of the transfer switch.
3. Turn ON the utility power supply to the transfer
switch, using the means provided (such as a utility
main line circuit breaker).
NOTE: Transfer switch will transfer back to utility
position.
4. Set the generator main circuit breaker to ON or
CLOSED.
5. Push the generator AUTO button. The system is
now ready for automatic operation.
6. Turn OFF the utility power supply to the transfer
switch.
(000132)
With the generator ready for automatic operation, the
engine should crank and start when the utility source
power is turned OFF after a 10 second delay (factory
default setting). After starting, the transfer switch should
connect load circuits to the standby side after a five (5)
second delay. Let the system operate through its entire
automatic sequence of operation.
With the generator running and loads powered by
generator AC output, turn ON the utility power supply to
the transfer switch. The following should occur:
• After approximately 15 seconds, the switch should
transfer loads back to the utility power source.
• Approximately one minute after re-transfer, the
engine should shut down.

Installation Summary

1. Ensure that the installation has been properly per-
formed as outlined by the manufacturer and that it
meets all applicable laws and codes.
2. Test and confirm proper operation of the system as
outlined in the appropriate installation and owner's
manuals.
3. Educate the end-user on the proper operation,
maintenance and service call procedures.
