4.4.2 Controller Keypad
The Run, Off, Auto, and Down arrow or Exercise buttons
control the generator set as described in Figure 4-5.
See Section 4.5 for operation instructions.
RDC controller (RES models) only: The Select, Up,
and Down buttons on the controller keypad are used to
adjust the controller parameters. The system
configuration and performance is factory-set and
should not require changes under normal operating
conditions. To prevent inadvertent changes, a pass
code is required to access the controller parameter
settings. See the generator set Installation Manual for
controller configuration instructions. See Section 5.8 of
this manual for performance adjustment instructions.
For the DC controller (RESL models), a personal
computer with Kohlerr SiteTecht software is required
for system configuration changes and performance
adjustment.
