If the troubleshooting procedures in Section 5 identify a
failed controller, use the procedure in this section for
controller replacement. Always check the controller
settings, wiring, and connections before replacing the
controller.
Some setup is required after the new controller is
installed. There are several ways to set up the
controller:
D The controller can be set up using the buttons on the
controller.
D The controller can be set up using a personal
computer and Kohlerr SiteTecht software.
D If a controller settings file was created at installation
or at some other time when the controller was known
to be operating correctly, a personal computer
(laptop) with Kohler SiteTech software can be used to
load the settings onto the new controller.
Note: Load the old controller settings onto the new
controller only if you are certain that the settings
are correct. Many controller operation problems
can be caused by incorrect settings.
In some cases, the Kohler Generator Service
Department may provide a settings file to load onto the
controller for testing or troubleshooting. See TP-6701,
SiteTech Software Operation Manual, for instructions to
export and import settings after controller replacement.
