Initial Start‑up (No Load)
Before operating the generator or placing it into service,
inspect the entire installation carefully. Then begin testing the
system without any electrical loads connected, as follows:
Unit has been set-up for NG or LP vapor operation at the
factory. Fuel conversion, if needed, must be completed
prior to performing these steps. See
Fuel Conversion
, later in
this manual.
1. Connect an accurate AC voltmeter and a frequency
meter to check generator output at load side of
circuit breaker.
2. Set generator’s circuit breaker to its ON
(closed) position.
4. Install control board fuse in control board.
5. Press appropriate button on control board to allow
engine to start.
When the generator is started for the very first time,
it will require that air in the gaseous fuel lines be
purged. This may take a few minutes.
6. Listen for unusual noises, vibration or other
indications of abnormal operation. Check for oil or
coolant leaks while engine runs.
7. Let engine warm up for about five minutes to allow
internal temperatures to stabilize.
8. No-load voltage should be 239 - 244 Volts*, frequency
should be 59.8 - 60.2 Hz.
If AC voltage is outside these ranges, perform the
generator adjustment, Steps 11 and 12 below.
9. Check generator output between one of the generator
connection lugs and the neutral lug, then between the
other generator connection lug and the neutral lug.
In both cases, voltage reading should be 117 - 123
Volts.*
DO NOT proceed until you are certain that generator
AC voltage is correct and within the stated limits.
Generator frequency is fixed and not adjustable.
10. If voltage and frequency values are correct, proceed
to step 13.
11. Connect voltmeter as described in step 1 above.
12. While observing voltmeter, adjust alternator voltage
control (A) for 240 volts. DO NOT adjust either of the
other alternator controls.
13. Push appropriate button on control board to stop the
engine.
14. Install alternator circuit breaker enclosure cover.
* Refer to the table below to determine proper no-load
voltage.
