Code Fault Description Check
AF Auxiliary fault
input shutdown Input from a customer-supplied switch that closes
when the fault is active. Shutdown occurs
0.3 seconds after the fault is detected and will not start
when the fault is active (input is grounded). This
protection becomes active 3-seconds after crank
disconnect. Check the cause of the auxiliary fault.
HE High engine
temperature
shutdown Shutdown occurs if the engine coolant temperature
exceeds the maximum temperature for more than
5 seconds. This protection becomes active after the
engine reaches the crank disconnect speed.
Note:
The high engine temperature shutdown
functions only when the coolant level is in the
operating range.
Check for a low engine coolant level.
LOP Low oil pressure
shutdown Shutdown occurs if a low oil pressure condition exists
for more than 5 seconds. This protection becomes
active 30 seconds after the engine has reached crank
disconnect speed (30 second inhibit).
Note:
The low oil pressure shutdown does not protect
against low oil level. Check the oil level at the engine.
Check for leaks in the lubrication system.
Check the oil level and add oil if the level is low.
OC Overcrank
shutdown Shutdown occurs after 3 unsuccessful starting
attempts. The crank cycle is set for three starting
attempts. Check the fuel supply and battery.
If there is no output voltage, check the line circuit
breaker. Also check for loose connections.
Contact an authorized distributor/dealer for service if
problem continues.
OF Overfrequency
shutdown Shutdown occurs when the governed frequency
exceeds 110% of the system’s frequency setpoint for
more than 5 seconds. This protection becomes active
10 seconds after engine start (10 second inhibit). Contact an authorized distributor/dealer for service if
problem continues.
OS Overspeed
shutdown Shutdown occurs if the engine speed exceeds 115%
of the normal running speed for more than 0.3 seconds. Contact an authorized distributor/dealer for service if
problem continues.
OU Overvoltage
shutdown Shutdown occurs if the voltage exceeds 120% of the
voltage regulator setpoint for more than 2 seconds. Contact an authorized distributor/dealer for service if
problem continues.
UF Underfrequency
shutdown Shutdown occurs when the governed frequency falls
below 90% of the system’s frequency setpoint for
more than 5 seconds. This protection becomes active
10 seconds after engine start (10-second inhibit). Reduce the load and restart the generator set.
Contact an authorized distributor/dealer for service if
problem continues.
UU Undervoltage
shutdown Shutdown occurs if the voltage falls below 80% of the
voltage regulator setpoint for more than 10 seconds. Reduce the load and restart the generator set.
Contact an authorized distributor/dealer for service if
problem continues.
SCF0 Controller error Indicates a software or communication problem within
the ADC 2100. Contact an authorized distributor/dealer for service if
problem continues.

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
2 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
2 seconds. Check the battery rating and condition.
LB Low battery
voltage warning Fault code is displayed if the engine starting battery
voltage falls below 9.5 VDC for a 12 VDC system or
below 16 VDC for a 24 VDC system for more than
2 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
2 seconds. Check the battery rating and condition.
Charge or replace the battery.
