TP-6200 10/1238 Section 2 Operation
2.3.6 System 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.

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.
(W aukesha-powered models only. )
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
line-to-line. For voltage configurations greater than 240
volts and less than 600 volts, the critical voltage
shutdown monitors nominal voltage line-to-line with a
center tap connection. For voltage configurations of
600 volts and above, the critical voltage shutdown
monitors nominal voltage with a stepdown transformer
in the 208--240 voltage range.
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 D01-D21 or analog input
A01-A07 when activated.
Using the remote communications package, the user
can label the auxiliary functions. The controller displays
the selected name instead of digital input D01-D21 or
analog input A01-A07.
Defined Common Faults. The lamp illuminates and
the unit shuts down when one or more of the
(user-selected) defined common faults are energized.
The local display shows defined common fault.
Detonation Shutdown. The lamp illuminates and the
unit shuts down when the controller detects combustion
system detonation. The local display shows deton
shutdown. (Waukesha-powered models only. )
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.
(350--2000 kW generator sets only)
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.
