4.3 Initial Checks
When troubleshooting, always check for simple
problems first. Check for the following common
problems before replacing parts:
D Loose connections or damaged wiring.
D Dead battery.
D Inadequate fuel supply. Check for damaged
primary or secondary fuel regulators, loose
connections to the fuel solenoid valve, a damaged or
closed fuel shutoff valve, an empty LPG fuel tank, or
other problems with the fuel supply. Check the fuel
supply pressure to the generator set. See
Section 5.13, Fuel Systems.
D Fault shutdown. Check for a fault message on the
controller display. Section 4.9 describes the warning
and shutdown fault messages. If a fault message is
displayed, identify and correct the cause of the fault
condition. Then press the OFF button on the
controller to clear the fault.
D Incorrect controller settings. Always check the
controller settings before replacing the controller.
See Section 3.3.1 for controller settings. Refer to the
operation manual for instructions to check and
change the controller settings from the controller
keypad, or use a personal computer and Kohlerr
SiteTecht software.
4.4 USB Port
The USB port is accessible from the front of the
controller. See Figure 4-2.
Section 3.3 lists controller settings. Some s ettings can
be changed from the controller keypad. All other
adjustable settings require a personal computer
(laptop) with Kohlerr SiteTecht software for changes.
Use a USB cable with a mini-B connector to connect the
controller’s USB port to your PC.
See TP-6701, SiteTecht Software Operation Manual,
for software operation instructions.
4.5 Circuit Protection
Line Circuit Breaker
The line circuit breaker interrupts the generator output in
the event of an overload condition or a fault in the wiring
between the generator and the load. If the circuit
breaker trips, reduce the load and check the wiring.
Auxiliary Winding Circuit Breaker
The auxiliary winding circuit breaker (mini-breaker) in
the connection area protects the alternator’s auxiliary
winding. If the breaker trips, check connections 55, 66,
FP, and FN to the alternator.
