7. Turn off all electrical loads. Initial testing
and adjustment should be conducted with
the generator at “no-load.”
8. To start the generator engine manually, set
the AUTO/OFF-RESET/MANUAL switch to
the MANUAL position, engine starts. Let the
unit stabilize and warm up for a few min-
utes.
9. Set the main circuit breaker on the genera-
tor to the ON position.
10. With an accurate AC voltmeter, verify that
correct rated voltage and frequency are
being supplied to transfer switch terminals
E1, E2, and neutral.
a.Do not proceed until generator output
frequency and voltage are correct.
b.If AC frequency is not within 60-62 Hz
at no-load, contact authorized service
technician.
DO NOT attempt to adjust the governor. Only
qualified service facilities should adjust the
governor. Excessively HIGH operating speeds
are dangerous and increase the risk of personal
injury. LOW speeds impose a heavy load on the
engine when adequate engine power is not
available and may shorten engine life. Correct
rated frequency and AC voltage are supplied only
at the proper governed speed. Incorrect AC
frequency and/or voltage may damage some
connected electrical load devices. IT IS RECOM-
MENDED THAT ONLY QUALIFIED SERVICE
TECHNICIANS ADJUST THE ENGINE GOVER-
NOR.
NOTE: On units connected for 240 volts,
1 phase output, line-to-line voltage at 62 Hz
should be 240-250 volts. Take these initial readings
with the generator running at no-load.
IMPORTANT: DO NOT PROCEED UNTIL NO
LOAD FREQUENCY AND VOLTAGE ARE
CORRECT.
11. Verify that all utility power has been turned
OFF to the transfer switch with whatever
means provided. Then, manually actuate
the transfer switch main contacts to the
STANDBY position, i.e., LOAD connected
to the GENERATOR.
12. Turn ON electrical loads that almost equal
the generator’s wattage amperage capac-
ity. With an AC frequency meter, check
frequency at transfer switch terminals E1
and E2. With generator under load, fre-
quency should not drop below 58 Hz.
13. Let the generator run under load for at
least 20-30 minutes. Check for unusual
vibration, noise, high temperature, and
other indications of abnormal operation.
MANUAL RETRANSFER AND SHUT DOWN
Electrical loads may be retransferred back to
the utility power and the generator can be
shutdown as follows:
1. Verify that utility power supply to the trans-
fer switch has been positively turned OFF,
using whatever means provided (such as
the utility main line circuit breaker).
2. Set the generator’s main circuit breaker to
its OFF position.
3. Let the generator engine run at no-load for
several minutes to stabilize internal unit
temperatures.
4. On the generator control panel, set the
AUTO/OFF-RESET/MANUAL switch to
OFF. Wait for engine to come to a com-
plete stop.
