ECM Model Mismatch. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when the controller
detects an error with the ECM model. The local display shows ECM Mismatch Shutdwn.
Emergency Stop. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when the local or optional
remote emergency stop switch activates. The local display shows Emerg Stop Shutdwn.
Enclosure Temperature: High Shutdown (Available on select Telecom units only). The fault lamp illuminates red, the alarm
horn sounds, and the unit shuts down when the enclosure reaches high temperature. The digital input does not function during
first the 20 seconds after startup and has a 5 second delay. The local display shows Enclsr Temp: High Shutdwn.
Engine Over Speed. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down immediately when the
governed frequency on 50 and 60 Hz models exceeds the over speed setting. The local display shows Eng Speed High Shutdwn.
Engine Under Speed. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down immediately when the
governed frequency on 50 and 60 Hz models drops below the under speed setting. The local display shows Eng Speed Low
Shutdwn.
File System Error. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when the internal controller
diagnostics detect a firmware file error. The local display shows File Error Shutdwn.
Fuel Tank Leak (diesel-powered models only). The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down
when the fuel tank signals a leak of the inner tank. This fault requires an optional fuel tank leak switch for the lamp to function.
The local display shows Fuel Leak Shutdwn.
High Coolant Temperature. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down because of high
engine coolant temperature. The high coolant temperature shutdown does not function during the preset inhibit time delay period
after startup. The local display shows Coolnt Temp High 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.
Internal Fault. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when the internal diagnostics
detect a controller malfunction. The local display shows Intern Error Shutdwn.
kW Overload. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when the generator set supplies
more than 102% of the rated standby output kW (or 112% of the rated prime power output kW) for more than 60 seconds. The
local display shows Total Power High Shutdwn.
Locked Rotor (failed to crank). If none of the speed sensing inputs show engine rotation within the preset time delay of initiating
engine cranking, the ignition and crank circuits turn off for the preset period and the cycle repeats. The fault lamp illuminates
red, the alarm horn sounds, and the unit shuts down after the second cycle of the preset period of cranking. The local display
shows Locked Rotor Shutdown.
Loss of Fuel. The fault lamp illuminates red and the alarm horn sounds when the unit shuts down without receiving a signal
from the controller to do so. On diesel-fueled units this condition includes fuel pump failure, loss of fuel prime, and/or an empty
fuel tank. On gaseous-fueled units this condition includes loss of fuel pressure and/or an empty fuel tank. The local display
shows Loss of Fuel.
Low Coolant Level. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down because of low coolant
level. Shutdown occurs 5 seconds after low coolant level is detected. Local display shows Coolant Lvl Low Shutdwn.
Low Engine Oil Level. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down because of low engine
oil level. This fault feature requires an optional low engine oil level sensor for the lamp to function. Local display shows Oil Level
Low Shutdwn.
Low Fuel Level (diesel-powered models only). The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down
when the fuel tank level on diesel-fueled models approaches empty. This fault requires an optional low fuel level switch for the
lamp to function. The local display shows Fuel Level Low Shutdwn.
Low Oil Pressure. The fault lamp illuminates red, the alarm horn sounds, and 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 Oil Press Low Shutdwn.
MegaJector Communications Loss (GM/PSI and Doosan gas-powered models only). The fault lamp illuminates red, the
alarm horn sounds, and the unit shuts down when the communication link is disrupted. The local display shows MJ Comm Loss.
