6 Operation

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.

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.
