Name Description
Generator set master Switch functions as the controller reset
switch and generator set operation switch.
Hourmeter Hourmeter records the generator set
total operating hours for reference in
maintenance scheduling.
Voltage regulator fuse, Fuse protects the voltage regulator
10-amp circuitry.
Controller fuse, 10-amp Fuse protects the controller circuitry
from short circuits and overloads.
AC circuit breaker Circuit breaker trips when a fault is
detected in the AC output circuit.
Fault lamp Lamp lights when a fault shuts the
generator set down and remains lit until
the generator set master switch is
moved to the OFF/RESET position.
See Section 2.3.4 for fault shutdown
information.

Stopping the Generator Set

The following procedures describe the actions required
to stop the generator set.
Automatic Stopping
1. The ATS or other device disconnects the load from
the generator set.
2. The generator set continues to run for a preset
cooldown time if the ATS is equipped with an
engine cooldown time delay.
3. The ATS or other device opens the connection
between controller terminals TB1-3 and TB1-4.
The generator set shuts down if the generator set
master switch is in the AUTO position.
Local Stopping
1. Cooldown. Run the generator set at no load for at
least 2 minutes to ensure adequate engine
cooldown.
2. Stopping. Move the generator set master switch
to the OFF/RESET position. The engine stops.
