Maintenance

Servicing the System

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.

Service Code Detection 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 Oil Temperature
• Transfer Switch Service code
• No Wireless Communication
• Battery Charge Circuit

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.
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 home 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.
