Controller Information
The following data must be resident for the controller to function.
• Application program contains the software that controls system operation. The application file was preprogrammed
in the original controller at the factory.
• Personality profile is specific to the engine and alternator and was preprogrammed in the original controller at the
factory.
Typically, the Kohler authorized distributor/dealer creates a backup of the personality profile and passes this information
onto the owner. Inform the owner to store this information for possible future use such as controller replacement or
other circumstances requiring a backup.
Note:
If the personality profile is NOT available, request a replacement from Kohler Aftermarket Parts Department.
Enter an aftermarket parts order for part number PROFILE. Include in the order notes the generator set model,
specification number, serial number, generator set modifications, and email of recipient.
• User parameters unique to an installation include timer values, setpoints, generator set data such as voltage and
input/output selections. These parameters are typically set up for or by the installer at the time of installation. User
parameters are typically recorded on the personality profile disk, a separate backup disk/drive, or written on a paper
form.
Note:
If the user parameters are included on the personality disk, the disk label should indicate Site Program—Yes.
Note:
After the unit is set up on the vessel, Kohler authorized distributor/dealer saves any user parameter changes to an
external medium. Kohler authorized distributor/dealer passes this information onto the owner. The owner should store
this information for possible future use such as controller replacement or other circumstances requiring a backup.
Note:
Controller service replacement kits do not include the three files. The service technician must install the three files into
the replacement controller.
