11. Verify gas pressure while under full load. Record
loaded gas pressure: ______________.
12. When testing under load is complete, turn off
electrical loads.
13. Set the generator MLCB (generator disconnect) to
OFF (OPEN).
14. Let the engine run at no-load for 2–5 minutes.
15. Push the generator OFF 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 that gas piping may be undersized or restricted.
It may also indicate that 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 that the generator is off.
2. Install the 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
MLCB).
NOTE: Transfer switch will transfer to utility position.
4. Set the generator MLCB (generator disconnect) to
ON (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.
The generator is ready for automatic operation. The
engine will crank and start when the utility source power
is turned OFF after a 10 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. 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, 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 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.
Shutting Generator Down While
Under Load
IMPORTANT NOTE: To avoid equipment damage,
follow these steps, in order, when shutting the generator
down during utility outages. Shutdowns may be required
during outages to perform routine maintenance or to
conserve fuel.
To turn the generator OFF (while running in AUTO
and online):
1. Turn the main utility disconnect off.
2. Turn the generator MLCB (generator disconnect)
to OFF (OPEN).
3. Run the generator for approximately one minute for
proper cooling.
4. Turn the generator OFF.
To turn the generator back ON:
1. Put the generator into AUTO. Start generator and
warm-up for a few minutes.
2. Set the MLCB (generator disconnect) to ON
(CLOSED).
The system now operates in automatic mode. The main
utility disconnect can be turned ON (CLOSED). To shut
the unit off, repeat this complete process.
