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