configuration.
This section contains instructions for using the
controller's password-protected menus to check and
adjust the generator output and controller configuration.
The controller configuration and generator set output
are factory-set and should not require field adjustment
under normal circumstances. Check and adjust the
configuration and/or output when:
D
The controller has been replaced.
D
The voltage requires adjustment for a particular
application.
D
Troubleshooting generator set problems.
Have controller setup and adjustment performed only by
a Lennox dealer or authorized representative.
3.1 Controller Automatic Power
Down
With the generator set master switch in the AUTO
position, there are three possible controller power
modes.
48-hour power down. If the controller is not configured
for a CAN gauge (communications parameter setting
Cn00, see Section 3.3), the controller will power down
after 48 hours of no activity. If the generator set has
been started, the controller will power down 48 hours
after the generator stops. A remote start signal from a
transfer switch or remote switch connected to engine
start leads 3 and 4 will signal the controller to power up
and the generator set to start.
Continuous power mode.

parameter to Cn06 will cause the controller to power
down after 1 hour of no activity. In this mode, a remote
start/stop switch or the generator set master switch
must be used to activate the controller after it has
powered down. Controller application code version
1.21 or higher is required for the 1--hour power down
option.
3.2 Code Version
Generator sets with serial numbers above 2272938
require ADC 2100 application code version 3.25 or later.
The code version is displayed as you enter the controller
configuration mode. See Figure 3-2.
3.3 Controller Configuration
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 3-1, if necessary.
Note: If the controller is replaced, the new controller will
need to be configured to the settings for the
generator set as described in this section.
Note: The controller will automatically exit the
configuration mode without saving any changes
after about 1 minute if no buttons are pressed.
Start the configuration procedure over again from
the beginning if the controller exits the
configuration mode before the settings have
been saved.
