1.14.3 RDC Controller Configuration
In order to prevent inadvertent changes, a code is
required to enter configuration mode. With the
controller in OFF, hold the select button and press the up
arrow button for 5 seconds. The controller display will
show the software version. Press the arrow buttons in
the following order to enter configuration mode: down,
up, down, up, down, up.
Follow the instructions in Figure 1-31 to enter the
configuration mode while the engine is not running and
then step through the following parameters. Use the up
(∧) and down (∨) arrow buttons to select the appropriate
settings for the application.
If no buttons are pressed for one minute, the controller
will automatically exit the configuration mode without
saving any changes. Start the configuration procedure
over again from the beginning if the controller exits the
configuration mode before the settings have been
saved.
Note: Be sure to save your settings before exiting the
configuration mode. The controller reverts to the
last saved settings when the OFF button is
pressed.
System voltage/frequency setting (Uu). Select the
system voltage and frequency from the table in
Figure 1-30.
Note: The Uu parameter sets the system’s rated
voltage and frequency. To adjust the output
(measured) voltage and frequency, see Section
1.15, Voltage and Frequency Adjustments.
Engine configuration (Ec). The engine configuration
must match the generator set engine type. See
Figure 1-30.

Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
areinplace.
Moving parts.
WARNING
Short circuits. Hazardous voltage/current can cause
severe injury or death. Short circuits can cause bodily injury
and/or equipment damage . Do not contact electrical
connections with tools or jewelry while making adjustments or
repairs. Remove all jewelry before servicing the equipment.
The generator output voltage and frequency can be
adjusted, if necessary. Have adjustments performed by
an authorized distributor/ dealer or service technician.
The generator set must be running during performance
adjustments.
Note: A digital multimeter that measures voltage and
frequency is required for these adjustments.
Use a digital multimeter to check the output voltage and
frequency. If output voltage or frequency is not within
specifications, use the controller keypad to adjust the
output voltage and engine speed (frequency) while the
generator set is running. See Figure 1-29. The
flowchart in Figure 1-31 outlines the adjustment
procedures.
Note: Be sure to save your changes as instructed in
Figure 1-31 before exiting configuration mode.
Changes in voltage and speed adjustments are lost if
not saved before the generator set shuts down. The
generator set continues to run with the new settings until
it shuts down but then reverts to the previous settings at
the next startup if the changes have not been saved.
Note: The DC controller cannot be adjusted from the
controller keypad.
An authorized Kohler distributor/dealer can adjust the
voltage and frequency on both the RDC and DC
controllers using Kohlerr SiteTecht software and a
personal computer. Contact an authorized Kohler
distributor/dealer for service.
