The generator is equipped with an exercise timer.
During the exercise period, the unit runs for
approximately 20 minutes and then shuts down.
Electrical load transfer DOES NOT occur during the
exercise cycle (unless an utility power outage occurs).
The generator will only enter the exercise cycle if the
unit is in the AUTO mode and this exact procedure is
followed.

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
• Battery Charge Circuit
