Installation Guidelines for 60 Hz Air-Cooled Generators 39
8. Verify gas pressure while running. Record running
gas pressure:________
9. Set the generator main line circuit breaker
(generator disconnect) to ON (CLOSED). Loads
are now powered by the standby generator.
10. Turn on the circuit breakers/electrical loads to be
powered by the generator one by one.
11. Connect a calibrated AC voltmeter and a frequency
meter across terminal lugs E1 and E2. Voltage
should be approximately 240 volts and frequency
should be approximately 60 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 output current
measurement of loads and/or fuel pressure.
12. Allow generator to run at full rated load for 20–30
minutes. Listen for unusual noises, vibration, or
other indications of abnormal operation. Inspect for
oil leaks, evidence of overheating, etc.
13. Verify gas pressure while under full load. Record
loaded gas pressure: ______________.
14. When testing under load is complete, turn OFF
electrical loads.
15. Set the generator main line circuit breaker
(generator disconnect) to OFF (OPEN).
16. Let the engine run at no-load for 2–5 minutes.
17. Press the generator OFF mode button. The engine
will shut down.
NOTE: If gas pressure under full load is below the
minimum operating pressure guideline, the generator
may not function properly. The pressure gauge needle
should also remain steady while testing. A fluctuating
needle indicates gas piping may be undersized or
restricted. It may also indicate a step-down gas regulator
is too small, or too close to the unit.
Checking Automatic Operation
Proceed as follows to check the system for proper
automatic operation:
1. Verify generator is OFF.
2. Install front cover of transfer switch.
3. Turn ON utility power supply to transfer switch
using the means provided (such as a utility MLCB).
NOTE: Transfer switch will transfer to utility position.
4. Set generator main line circuit breaker (generator
disconnect) to ON (CLOSED).
5. Press generator AUTO button. System is now
ready for automatic operation.
6. Turn OFF utility power supply to transfer switch.
The generator is ready for automatic operation. The
engine will crank and start when the utility source power
is turned OFF after a five second delay (factory default
setting). After starting, the transfer switch will connect
load circuits to the standby side after a 5 or 30 second
delay (dealer programmable). See Cold Smart Start.
Allow the system to operate through the 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 will occur:
• After approximately 15 seconds (dealer
programmable), the switch will transfer loads to the
utility power source.
• Approximately one minute after re-transfer, the
engine will shut down.
Installation Summary
1. Verify the installation has been properly performed
as outlined by the manufacturer and 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.
