Description
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.
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.
Not used.
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.
Shutdown occurs after 3 unsuccessful starting
attempts. The crank cycle is set for three starting
attempts.
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).
Shutdown occurs if the engine speed exceeds 115%
of the normal running speed for more than 0.3 seconds.
Shutdown occurs if the voltage exceeds 120% of the
voltage regulator setpoint for more than 2 seconds.
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).
Shutdown occurs if the voltage falls below 80% of the
voltage regulator setpoint for more than 10 seconds.
Indicates a software or communication problem within
the ADC 2100.
Description
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.
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
Check the cause of the auxiliary fault.
Check for a low engine coolant level.
Check for leaks in the lubrication system.
Check the oil level and add oil if the level is low.
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.
Check engine speed and adjust governor if necessary.
Contact an authorized distributor/dealer for service if
problem continues.
Contact an authorized distributor/dealer for service if
problem continues.
See Section 6.4, High Generator Output Voltage.
Contact an authorized distributor/dealer for service if
problem continues.
Reduce the load and restart the generator set.
Check engine speed and adjust governor if necessary.
Contact an authorized distributor/dealer for service if
problem continues.
Reduce the load and restart the generator set.
See Section 6.4, Low Output Voltage.
Contact an authorized distributor/dealer for service if
problem continues.
Replace the ADC 2100.
Check
Check the battery rating and condition.
Check the battery rating and condition.
Charge or replace the battery.
