TP-6331 5/046 Section 2 Operation
Code Fault Description Check
HB High battery
voltage warning
Fault code is displayed if the engine starting battery voltage rises
above 16 VDC for a 12 VDC system or above 30 VDC for a
24 VDC system for more than 10 seconds when the engine is not
running. This fault condition does not inhibit engine starting.
The fault condition clears when the battery voltage returns to a
voltage within the limits for more than 10 seconds.
Check the battery rating and condition.
Check the battery charger operation.
LB Low battery
voltage warning
Fault code is displayed if the engine starting battery voltage falls
below 8 VDC for a 12 VDC system or below 16 VDC for a 24 VDC
system for more than 10 seconds when the engine is not running.
This fault condition does not inhibit engine starting.
The fault condition clears when the battery voltage returns to a
voltage within the limits for more than 10 seconds.
Check the battery rating and condition.
Check the battery charger operation.
Charge or replace the battery.

2.4.1 Resetting Controller after a Fault
Shutdown
Always identify and correct the cause of a fault
shutdown before resetting the controller. Use the
following procedure to reset the generator set controller
after a fault shutdown.
1. Move the generator set master switch to
OFF/RESET.
2. Disconnect the generator set from the load using
the line circuit breaker or ATS. See the safety
precautions at the beginning of this section before
proceeding.
3. Identify and correct the cause of the fault
shutdown. See the safety precautions at the
beginning of this section before proceeding. Refer
to Section 4, Troubleshooting.
4. Start the generator set by moving the generator set
master switch to RUN. Test operate the generator
set to verify that the cause of the shutdown has
been corrected.
5. Move the generator set master switch to
OFF/RESET.
6. Reconnect the generator set to the load using the
line circuit breaker or ATS.
7. Move the generator set master switch to the AUTO
position for startup by remote transfer switch or
remote start/stop switch.
Note: The controller’s LED display remains off
until an engine start command is received.
Opening and closing a remote start/stop contact also
resets the controller.
2.5 Continuous Power Mode
The ADC 2100 is powered by the generator set engine
starting battery. A jumper on the back of the controller
maintains power to the controller at all times.
Controllers are shipped with the jumper connected.
Note: The 8.5 and 12 RES generator sets are equipped
with factory-installed battery chargers to prevent
battery discharge.
Disconnecting the jumper allows the controller to power
down automatically 48 hours after the generator set
shuts down if the generator set master switch is in the
AUTO position. A remote start signal (from a transfer
switch or a remote start/stop switch connected to
controller leads 3 and 4) or moving the generator set
master switch to the RUN position turns the controller
back on.
Contact an authorized distributor/dealer to disconnect
the jumper, if necessary.
