High Oil Temperature. The lamp illuminates and the unit shuts down because of high engine oil temperature. The shutdown occurs 5 seconds after the engine oil reaches the temperature shutdown range. The high engine oil temperature shutdown does not function during the first 30 seconds after startup. The local display shows high oil temp sdwn.
Intake Air Temperature. The lamp illuminates and the unit shuts down because of high intake air temperature. The shutdown occurs 5 seconds after the engine intake air reaches the temperature shutdown range. The engine intake air temperature shutdown does not function during the first 30 seconds after startup. The local display shows intake air temp shutdown (DDC/MTU models with MDEC/ADEC) and 03 intake air temp shutdown
Internal Fault. The lamp illuminates and the unit shuts down when the internal diagnostics detect a controller malfunction. The local display shows internal fault.
Knock Shutdown. The lamp illuminates and the unit shuts down when the controller detects a detonation fault. The local display shows knock shutdown.
Locked Rotor. If none of the speed sensing inputs show engine rotation within 5 seconds of initiating engine cranking, the ignition and crank circuits turn off for 5 seconds and the cycle repeats. The unit shuts down after the second cycle of 5 seconds of cranking. The local display shows locked rotor.
Loss of ECM Communications. The lamp illuminates and the unit shuts down when the ECM communication link is disrupted. The local display shows loss of ECM comm.
Loss of Field (Reverse VARs). The lamp illuminates and the unit shuts down when the reactive current into the alternator (absorbing) exceeds the shutdown level. This could be caused by a disruption of the field signal. The local display shows sd loss of field. (Paralleling applications only.)
Low Coolant Level. The lamp illuminates and the unit shuts down because of low coolant level. Shutdown occurs 5 seconds after low coolant level is detected. Low coolant level shutdown is inhibited during the first 30 seconds after startup. Local display shows low coolant lvl.
Low Coolant Temperature. The lamp illuminates and the unit shuts down because of low coolant temperature. Shutdown occurs 5 seconds after low coolant temperature is detected. Low coolant temperature shutdown is inhibited during the first 30 seconds after startup. Local display shows low coolant temp shutdown. (DDC/MTU models with MDEC/ADEC only.)
Low Fuel (Pressure) Shutdown. The lamp illuminates and the unit shuts down when the controller detects a low fuel condition. The low fuel (pressure) shutdown does not function during the first 5 seconds after startup. The local display shows low fuel shdown. (125RZG only.)
(Low) Oil Pressure Shutdown. The lamp illuminates when the unit shuts down because of low oil pressure. The shutdown occurs 5 seconds after the low pressure condition is detected. The low oil pressure shutdown does not function during first the 30 seconds after startup. The local display shows (low) oil press shutdown.
Master Switch Error. The lamp illuminates and the unit shuts down when the controller detects a fault in the master switch position or circuit. The local display shows master switch error.
Master Switch Open. The lamp illuminates and the unit shuts down when the controller detects an open circuit in the master switch circuit. The local display shows master switch open.
Master Switch to Off. The lamp illuminates and the unit shuts down when the master switch is moved to the off position. The local display shows master switch to off.
NFPA 110 Fault. The lamp illuminates and the unit shuts down when NFPA 110 faults signal the controller. The local display shows the respective fault message. See Section 2.4, Menu List Summary, Menu
No Coolant Temperature Signal. The lamp illuminates and the unit shuts down when the engine coolant temperature sender circuit is open. The local display shows no cool temp signal.
No Oil Pressure Signal. The lamp illuminates and the unit shuts down when the engine oil pressure sender circuit is open. The local display shows no oil press signal.
Overcrank. The lamp illuminates and cranking stops when the unit does not start within the defined cranking period. The local display shows overcrank. See Section 2.3.1, Auto Starting, and Section 1, Specifications and Features, for cyclic crank specifications.
Note: The controller is equipped with an automatic restart function. When speed drops below 13 Hz (390 rpm) while the engine is running, the unit attempts to recrank. The unit then follows the cyclic cranking cycle and, when the engine fails to start, will shut down on an overcrank fault condition.
