40 Installation Guidelines for 60 Hz Air-Cooled Generators
9. Verify fuel pressure while running. Record running
fuel pressure:________
10. Set generator MLCB (generator disconnect) to ON
(CLOSED). Loads are now powered by standby
generator.
11. Turn on circuit breakers/electrical loads to be sup-
plied by generator one by one.
12. 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 voltage and fre-
quency are rapidly dropping as loads are applied,
generator may be overloading, or there may be a
fuel issue. Verify output current measurement of
loads and/or fuel pressure.
13. 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.
14. Verify fuel pressure while under full load. Record
loaded fuel pressure: ______________.
15. Turn off circuit breakers/electrical loads when test-
ing under load is complete.
16. Set generator MLCB (generator disconnect) to
OFF (OPEN).
17. Allow engine to run at no-load for 2–5 minutes.
18. Press generator OFF button. Engine will shut
down.
NOTE: If fuel pressure under full load is below minimum
operating fuel pressure guideline, generator may not
function correctly. The fuel pressure gauge needle should
also remain steady while testing. A fluctuating fuel pres-
sure gauge needle indicates gas piping may be under-
sized or restricted. It may also indicate a step-down gas
regulator is too small, or too close to unit.
Checking Automatic Operation
Proceed as follows to check system for correct 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 MLCB (generator disconnect) to ON
(CLOSED).
5. Press generator AUTO button. The 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 utility source power is
turned off after a five second delay (factory default set-
ting). After starting, transfer switch will connect load cir-
cuits to the standby side after a 5 or 30 second delay
(dealer programmable). See Cold Smart Start. Allow
system to operate through entire automatic sequence of
operation.
With generator running and loads powered by generator
AC output, turn on utility power supply to transfer switch.
The following will occur:
• After approximately 15 seconds (dealer
programmable), the transfer switch will transfer
loads to the utility power source.
• Approximately one minute after transfer, engine will
shut down.
Installation Summary
1. Verify installation has been performed correctly as
outlined by the manufacturer and that it meets all
applicable laws and codes.
2. Test and verify correct operation of the system as
outlined in the appropriate installation and owner’s
manuals.
3. Educate end-user on correct operation, mainte-
nance, and service call procedures.
Shutting Generator Down While
Under Load or During a Utility Outage
IMPORTANT NOTE: To avoid equipment damage,
follow these steps, in order, during utility outages.
Shutdowns may be required during utility outages to
perform routine maintenance or to conserve fuel.
To turn generator OFF:
1. Set utility MLCB to OFF (OPEN).
2. Set generator MLCB (generator disconnect) to
OFF (OPEN).
3. Allow generator to run for cool-down for approxi-
mately one minute.
4. Set generator to OFF at the controller.
5. Remove 7.5A fuse from controller.
To turn generator back ON:
1. Install 7.5A fuse in controller.
2. Verify generator MLCB (generator disconnect) is
OFF (OPEN).
3. Set generator to AUTO mode at the controller.
Automatic start-up. Disconnect utility power and
render unit inoperable before working on unit.
Failure to do so will result in death or serious injury.
