Maintenance

Servicing the System

Before performing any generating set maintenance,
always perform the following steps:
1. Set generating set's circuit breaker to its OFF
position.
2. Capture any service code display information
displayed on the control board.
3. Press and hold the control board OFF button.
4. Remove 15 Amp fuse from control board.
5. Utility voltage is present at generating
set control board. Disconnect power before
servicing control board by removing the fuses
from the transfer switch.
6. 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.
Service Code Detection System
The generating set 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 generating set in the event of potentially
damaging conditions, such as low oil pressure, high
temperature, over speed, and other conditions.
The generating set'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
• 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 condition, then return the home
generating set 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. This condition
occurs if the battery voltage drops below the preset
value. Causes for this problem may be an inoperative
battery or battery charge circuit. See Battery Charge
Circuit.
Remove the 15 Amp fuse and disconnect the battery
from the generating set. Test the battery voltage. If
voltage does not meet specification, replace battery or
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. The unit is equipped
with an oil pressure switch that uses normally closed
contacts held open by engine oil pressure during
operation. Should oil pressure drop below the 8 psi
range, switch contacts close and 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 code
will appear again. In this case, contact an authorized
dealer.
Under Voltage
This service code is indicated by Under Voltage
scrolling across the digital display. This condition is
caused by a restriction in the fuel flow, the electronic
governing system not functioning properly, a broken or
disconnected signal lead, a failed alternator winding,
the generating set is overloaded, or the overload fuse
is blown.
To remedy the problem, contact your installer or an
authorized dealer.
