TROUBLESHOOTING USING AL FAULT CODES
Alarm Fault Codes are shown on the upper display and consist of specific engine fault codes, protective relay
function codes, and paralleling fault codes. Alarm Fault Codes rely upon programmed setpoints.
Engine fault code programming is contained in OP5-0, Engine/Generator Programming (see WP 0083 for details).
Protective relay function code programming is contained in OP5-1, Protective Relay Programming (see WP 0083).
Paralleling fault code programming is contained in OP5-3, Synchronization Programming (see WP 0083).
Alarm Fault codes are not stored in the GSC fault log.
WARNING
Metal jewelry will conduct electricity. All jewelry can become entangled in generator set
components. Remove all jewelry when working on generator set. Failure to comply can cause
injury or death to personnel by electrocution.
High voltage is produced when this generator set is in operation. Make sure unit is completely
shut down and free of any power source before attempting any repair or maintenance on the unit.
Failure to comply can cause injury or death to personnel.
DC voltages are present at generator set electrical components even with generator set shut
down. Avoid shorting any positive with ground/negative. Failure to comply can cause injury to
personnel and damage to equipment.
Dangerously high voltage can exist across current transformer (CT) output with engine running.
CT could explode if disconnected from load with engine running. Do not disconnect CT with
generator rotating. Failure to comply can cause serious injury or death to personnel.
Slave receptacle (NATO connector) is electrically live at all times and is unfused. The Battery
Disconnect Switch does not remove power from the NATO connector. Use caution when
connecting or disconnecting cable(s) to the NATO connector to prevent damage to equipment.
Use caution when troubleshooting this circuit. This circuit is only dead when the batteries are fully
disconnected. Failure to comply can cause serious injury or death to personnel.
