Note: Text shown in italics in this manual represents digital display messages.
AC Sensing Loss. The lamp illuminates when the controller does not detect nominal generator set AC output voltage after crank disconnect. The local display shows AC sensing loss.
Battery Charger Fault. The lamp illuminates when the battery charger malfunctions. This fault feature requires an optional battery charger with a malfunction output for the lamp to function. Local display shows bat chgr fault.
Battle Switch. The lamp illuminates when in the battle switch mode. The local display shows battle switch.
Breaker Closed. The lamp illuminates when the respective circuit breaker is closed. The local display shows breaker closed. (Paralleling applications only.)
Breaker Trip. The lamp illuminates when the respective circuit breaker is tripped. The local display shows breaker trip. (Paralleling applications only.)
Common Protective Relay Output. The lamp illuminates when a common protective relay fault occurs. The local display shows common pr output. (Paralleling applications only.)
Customer Auxiliary (Warning). The lamp illuminates and the alarm horn sounds when an auxiliary digital or analog inputs signals the controller. The user can define inputs as shutdowns or warnings. The local display shows digital input
Using the remote communications package, the user can label the auxiliary functions. The controller displays the selected name instead of digital input
Defined Common Faults. The lamp illuminates and the alarm horn sounds when one or more of the
Detonation Warning. The lamp illuminates and the alarm horn sounds when the engine detects combustion system detonation. The local display shows deton warning.
ECM Yellow Alarm. The lamp illuminates and the alarm horn sounds when ECM yellow alarm signals the controller. The local display shows ECM yellow alarm. This fault only relates to the DDC/MTU engine with MDEC/ADEC. The user can navigate the menus to access the fault code. The engine operation manual provides the fault code descriptions.
Emergency Power System (EPS) Supplying Load. The lamp illuminates when the generator set supplies more than 1% of the rated standby output current. The local display shows EPS supplying load.
Ground Fault Detected. The lamp illuminates and the alarm horn sounds when a
High Battery Voltage. The lamp illuminates when the battery voltage rises above the preset level for more than 10 seconds. The local display shows high battery voltage. Figure

High Coolant Temperature Warning. The lamp illuminates and the alarm horn sounds when the engine coolant temperature approaches the shutdown range. The local display shows hi cool temp warning.
High Oil Temperature Warning. The lamp illuminates and the alarm horn sounds when the engine high oil temperatuare approaches the shutdown range. The local display shows hi oil temp warning (DDC/MTU models with MDEC/ADEC and
Idle (Speed) Mode. The lamp illuminates when in the idle (speed) mode. The local display shows idle mode active.
Intake Air Temperature Warning. The lamp illuminates and the alarm horn sounds when the engine intake air temperature approaches the shutdown range. The local display shows intake air temp warn (DDC/MTU models with MDEC/ADEC) and 03 intake air temp warn
Load Shed. The lamp illuminates when the generator set’s total kW load exceeds the programmed level for more than the load shed time. When the load shed alarm sounds and resets more than twice in 1 minute, the load shed warning lamp circuit latches and remains on until the generator set shuts down. The local display shows load shed kW over.
