Fault Condition/Trigger
(For configurable items, fault applies only if
configured. All listed conditions to be met
unless stated otherwise)
An engine with a CAN engine controller is not config-
ured in MACHINE SETUP:
The Engine State = ENGINE RUNNING > 10 seconds
The coolant temperature is greater than or equal to the
configured engines max allowed temperature. The
maximum allowed temperature > 110ºC.
An engine with a CAN engine controller is configured in
MACHINE SETUP:
ECM transmits a J1939 DM1 message for an engine
coolant high temperature critical fault (SPN:FMI 110:0)
on CAN2 or uses the J1939 Transport Protocol every one
second to send this information if multiple engine
faults exist.
The Engine State = ENGINE RUNNING > 10 seconds and
UGM system voltage < 11.5 volts for 10 seconds
An engine with a CAN engine controller is not config-
ured in MACHINE SETUP
The Engine State = ENGINE RUNNING > 10 seconds
The engine oil pressure is LOW (debounce 3s).
An engine with a CAN engine controller is configured in
MACHINE SETUP
ECM transmits a J1939 DM1 message for an engine oil
low pressure critical fault (SPN:FMI 100:1) on CAN2 or
uses the J1939 Transport Protocol every one second to
send this information if multiple engine faults exist.
MACHINE SETUP > ENGINE = DEUTZ EMR4;
ECM transmits a J1939 DM1 message for an engine
coolant low level fault (SPN:FMI 111:1) on CAN2 or uses
the J1939 Transport Protocol every one second to send
this information if multiple engine faults exist.
The engine has shut down because an unacceptable
amount of water has been detected in the fuel or there
is an issue with the water in fuel sensor.
If operating in platform mode, platform alarm will
sound continuously and low fuel indicator will flash.
If operating in ground mode, the ground alarm will
sound
