1.12 Controller Configuration

1.12.1 System Parameters

The controller configuration for each generator model is
set at the factory and should not normally require
changes. The controller's configuration mode allows
adjustment of the system parameters listed in this
section. Use the instructions in this section to check the
configuration after installation and change them to
match the settings shown in Figure 1-27, if necessary.

Figure 1-27 Controller Configuration Parameters
Follow the instructions in Figure 1-28 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
setting for the application.
The controller will automatically exit the configuration
mode without saving any changes after about 1 minute
if no buttons are pressed.
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 master switch is
moved to the OFF/RESET position.

1.13, Voltage and Frequency Adjustments.
Engine configuration (Ec). The engine configuration
must match the generator set engine type.
Controller type (Uc). The Uc setting is used during
initial controller installation in the factory or controller
replacement in the field. The Uc setting can be changed
only once. The default setting for service replacement
controllers is Uc05, controller type DC-RET. Changing it
to UC01 sets the controller type to ADC-RES. Uc01 is
the correct setting for the Model 12RES.
Communication/Sleep Mode Setting (Cn). (Available
on controllers with application code version 1.13 or
higher.) The communication setting enables or disables
J1939 communication, and also disables or enables the
sleep mode. When J1939 communication is enabled,
the sleep mode is turned off to allow uninterrupted
communication with a personal computer running
remote monitoring software. If remote monitoring is not
used, the communication can be turned off, enabling the
sleep mode which causes the controller to power down
after 48 hours of inactivity. The generator set master
switch must be in AUTO for the sleep mode to function.
The default setting for controllers with application code
version 1.13 or higher is Cn01, communication on/sleep
mode off. Controllers with earlier application code
versions have communication disabled and the sleep
mode enabled. The Cn setting is not adjustable on
these earlier versions.

1.12.2 Application Code Version

To check the application code version number, HOLD
the select button while moving the generator set master
switch to RUN. (The engine will not start when the select
button is held.) Wait about 5 seconds for the application
code version number to appear on the display. See
Figure 1-28.
