41
48 Vdc Precharge
Fault
Starter/Generator
This fault is reported when a
failure exists in the precharge
circuit that charges the 48 Vdc
line contactor. The 38 Vdc
minimum voltage was not
achieved.
The S/G must remain
connected because it
issues this fault.
The TEC will shut the
engine down and
disable the cutting
units (PTO).
The contactor will not
close.
Disconnect one motor at a time
until the fault is no longer active.
If one cutting unit motor is
reporting a communication fault,
that is likely the shorted motor.
43
Oil Temperature
Sensor Fault
Master
This fault is reported when the
oil temperature sensor is open,
not shorted. Shorts are ignored
because a shorting plug is
installed when the optional
sensor is not installed. This is a
diesel machine option.
This fault is for diesel
engine-equipped units
only.
1) Inspect the oil temperature
circuit for loose wire or
connector.
2) Test the temperature sensor.
44
48 Vdc Battery
Undervoltage
Cutting unit
This fault is reported when all 4
individual 48 Vdc bus circuit low
voltage alerts are active at the
same time.
This is indicative of
low battery power,
since individual cutting
unit or
starter/generator
failures would report
individually.
The TEC will disable
the cutting units (PTO)
and the generator will
not provide voltage.
3) Test the battery voltage.
4) Inspect the battery terminal
connections.
5) Test the internal S/G
connections.
6) Test the S/G for proper function.
7) Test the 48 Vdc logic relay for
proper function.
