2.3.6System Shutdown Lamp
The red lamp illuminates, the alarm horn sounds, and the unit shuts down to indicate a fault shutdown under the following conditions. See Section 2.3.7, Controller Reset Procedure, for information on resetting a system shutdown.
Use the Alarm Off keypad switch to silence the alarm horn at the operator’s discretion. Place the generator set master switch in the AUTO position before silencing the alarm horn. The alarm horn will not stop sounding unless the master switch is in the AUTO position.
Note: The text shown in italics represents digital display messages.
Air Damper Indicator. The lamp illuminates and the unit shuts down when signaled by a closed air damper circuit. The local display shows air damper indicator.
Air/Fuel Module. The lamp illuminates and the unit shuts down when the controller detects a fault with the air/fuel module. The local display shows afm shutdown.
Alternator Protection. The lamp illuminates and the unit shuts down because of an alternator overload or short circuit. The local display shows altrntr protect sdwn. See Appendix D, Alternator Protection for more information.
Critical Overvoltage. The lamp illuminates and the unit shuts down when the voltage exceeds 275 volts. The local display shows critical overvoltage.
For voltages configurations of 240 volts and less, the critical voltage shutdown monitors nominal voltage
Customer Auxiliary (Shutdown). The lamp illuminates and the unit shuts down when an auxiliary digital or analog input 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 unit shuts down when one or more of the
Detonation Shutdown. The lamp illuminates and the unit shuts down when the controller detects combustion system detonation. The local display shows deton shutdown.
ECM Red Alarm. The lamp illuminates and the unit shuts down when the controller receives a signal from the engine. The local display shows ECM red 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.
EEPROM Write Failure. The lamp illuminates and the unit shuts down when the control logic detects a data save error. The local display shows EEPROM write failure.
(Engine) J1939 CAN Shutdown. The lamp illuminates and the unit shuts down when the control logic detects an engine ECM communication signal interruption. The local display shows J1939 CAN shutdown.
Engine Stalled. The lamp illuminates and the unit shuts down when the control logic detects an engine ECM signal that the engine has stalled. The local display shows engine stalled and no attempts to restart the engine will occur.
Emergency Stop. The lamp illuminates and the unit shuts down when the local or optional remote emergency stop switch activates. The local display shows emergency stop.
Field Overvoltage. The lamp illuminates and the unit shuts down when the controller detects field overvoltage. The local display shows field over volts.
High Coolant Temperature Shutdown. The lamp illuminates and the unit shuts down because of high engine coolant temperature. The shutdown occurs 5 seconds after the engine reaches the temperature shutdown range. The high engine temperature shutdown does not function during the first 30 seconds after startup. The local display shows hi cool temp shutdwn.
Note: The high engine temperature shutdown function and the low coolant level shutdown function are independent. A low coolant level condition may not activate the high engine temperature switch.
