Maintenance
Before performing any generator maintenance, always
perform the following steps:
1. Set generator’s circuit breaker to its OFF position.
2. Press and hold the control board OFF button.
3. Remove 15 Amp fuse from control board.
4. Utility voltage is present at generator control board.
Disconnect power before servicing control board by
removing the fuses from the transfer switch.
5. After all servicing has been completed, replace fuses
in transfer switch, replace 15 Amp fuse in control
board, set circuit breaker ON and press and hold
control board AUTO button for 3 seconds.
Servicing the System
The generator may have to run for long periods of time
with no operator present. For that reason, the system is
equipped with sensors that automatically shut down the
generator in the event of potentially damaging conditions,
such as low oil pressure, high temperature, over speed, and
other conditions.
The generator’s control board shows service code
descriptions scrolling across the digital display. The service
code descriptions are listed below:
• Low Battery Voltage
• Low Oil Pressure
• Under Voltage
• Over Voltage
• Engine Does Not Start
• Low Frequency
• Engine Overspeed
• High Coolant Temperature
• Transfer Switch Service code
• No Wireless Communication
• Battery Charge Circuit
• Service Engine
Reset Service code Detection System
The operator must reset the service code detection system
each time it activates. To do so, press the control board OFF
button for 5 seconds. Once the display turns off, leave it off
for at least 30 seconds. Remedy the service code condition,
then return the generator to service by pressing and holding
the control board AUTO button and installing the 15 Amp
fuse (if removed).
Low Battery Voltage
This service code is indicated by Low Battery Voltage scrolling
across the digital display and a single flash on the wireless
monitor. This condition occurs if the battery voltage drops
below the preset value. Causes for this problem may be a
service code battery or battery charge circuit. See Battery
Charge Circuit,
Remove the 15 Amp fuse and disconnect the battery from
the generator. Test the battery voltage. If voltage meets
specifications, take the battery to a local battery store for
analysis. Or contact your local service center for assistance.
Reinstall the battery (replace if necessary - see Battery in
Final Installation Considerations in the installation manual).
Then reset the service code detection system, as described
earlier.
Low Oil Pressure
This service code is indicated by Low Oil Pressure scrolling
across the digital display and two flashes on the wireless
monitor. The unit is equipped with an oil pressure sensor that
is monitored by the engine ECU. Should oil pressure drop
below the 50 psi range, the engine will shut down.
To remedy the low oil pressure condition, add the
recommended oil to the FULL mark on the dipstick.
If the low oil pressure condition still exists, the engine will
start, then shut down again. The service code will appear. In
this case, contact an authorized dealer.
