Section 5 Troubleshooting
5.1 Introduction
Use the troubleshooting charts in this section to
diagnose and correct common problems. First check
for simple causes such as a dead engine starting
battery, loose connections, or an open circuit breaker.
The charts include a list of common problems,
possible causes of the problem, and recommended
corrective actions.
If the procedures in this manual do not explain how to
correct the problem, contact an authorized Kohler
distributor/dealer. Maintain a record of repairs and
adjustments performed on the equipment. Use the
record to help describe the problem and repairs or
adjustments made to equipment.
5.2 Fault Messages
The VSC controller displays fault messages to aid in
troubleshooting. Selected fault messages and
recommended checks are listed in Figure 2-5.
Identify and correct the cause of the fault condition.
Then reset the controller after a fault shutdown. See
Section 2.6.3.
5.3 Circuit Protection
If the generator set circuit breaker trips repeatedly,
contact an authorized Kohler distributor/dealer for
service.
5.3.1 Controller Internal Circuit
Protection
The controller is equipped with internal circuit
protection. A fault message, Accy PwrOver Warning
or MainPwrOverL Shutdown, is displayed if this
internal protection is activated. Press OFF to reset.
Contact an authorized Kohler distributor/dealer for
service.
5.3.2 Line Circuit Breaker
The line circuit breaker interrupts the generator output
in the event of a fault in the wiring between the
generator and the load. If the circuit breaker trips,
reduce the load and switch the breaker back to the ON
position.
5.4 Controller Service Access
A USB port is located in the service access area. See
Figure 5-1. Some controller settings can be adjusted
using a laptop computer with Kohler SiteTech
software. Use a USB cable with a mini-B connector to
connect the controller to your PC. See TP-6701,
SiteTech Software Operation Manual, for more
information.
