6. Make sure that the electrical loads to be powered by the
generator will not exceed the current ratings of the generator,
receptacle, or cord set which will supply the current.
7. Check all electrical connections in the system to be
energized by the generator. Make sure the connections are
correct and tight and the load disconnect plug (if provided) is
fully seated in the receptacle.
8. Make sure all loads are turned off. Do not start the generator
under load.
GENERATOR STARTING PROCEDURE
1. With the power take-off drive disengaged, start the engine
which will drive the generator. Run the engine long enough to
warm it up before proceeding, so that it will run smoothly and
achieve full power under generator load.
2. With engine idling, engage the power take-off drive.
3. Watch the frequency meter on the generator and slowly
increase engine speed until the frequency reaches approxi-
mately 60 Hz. The voltage output of the generator is controlled
by an Automatic Voltage Regulator (AVR). Before turning on
any load check your voltage output from the generator using a
volt/ohm meter. If the voltage is either high or low adjust the
voltage level by turning the voltage adjustment screw on the
AVR. The AVR is located inside the generator control cabinet.
Once the proper voltage level is set the AVR should bring the
voltage back to the same level each time the unit is started up.
But as a precaution it should be checked each time you use
the generator. As quick check you can plug in a troublelight
and check for normal brightness.
4. With engine and generator running smoothly, switch on the
electrical load while watching the frequency meter.
NOTE: Equipment Damage
If the load includes motors turn them on one at a time, highest
starting current motor first, next highest second, etc.
Adjust engine throttle to keep generator output under load at
60 Hz. If the engine is equipped a with governor, it may
automatically adjust the throttle as the load changes and keep
the generator output at the proper level. However, some
governors are not sensitive enough to maintain proper output
under changing loads, and in such cases the frequency will
have to be monitored closely and manually adjusted .
GENERATOR SHUTDOWN PROCEDURE
1. Switch off electrical load.
2. Reduce speed of engine driving generator to idle.
3. Disengage power take-off drive, and allow generator to
coast to a stop.
WARNING: Personal Injury
Never try to manually stop the generator. Always let it coast
until it stops.
3. Make sure the drive shaft (tumbling bar) is assembled with
its universal joint knuckles “synchronized,” as illustrated in
Figure 7. If knuckles are not synchronized, the bar will chatter
when rotating, which will cause the generator output voltage to
flicker.
DANGER: Personal Injury
POWER TAKE-OFF MUST BE DISENGAGED AT THIS TIME.
4. Couple the tractor to the generator with the drive shaft
(tumbling bar). Couple the tumbling bar to the generator input
shaft first, then to the power take-off shaft. Check alignment of
tractor, power take-off shaft (tumbling bar), and generator input
shaft should form a straight (or nearly straight) line, with less
than 15° misalignment between the shafts. Misalignment will,
stress the drive line and cause generator output voltage to
flicker.
CAUTION:
Make sure that all tumbling bar lock pins are engaged and
that all safety shields are in place before operating the PTO
generator.
5. Make sure no binding exists in generator or gear box. If
binding is found, locate the cause and correct it before
proceeding.
