High Temperature
Warning – Cutting
Reel Motor 5
Cutting Reel
Motor Controller
This fault is reported
when the cutting reel
motor temperature
exceeds 194 ºF (90 ºC).
• If the reel motor temperature
reaches 212 ºF (100 ºC), the
reel motor will be shut off.
• A side effect of this fault is
reduced reel speed and an
increased chance of a Fault
69, Speed Stall – CRM 5.
1) Reduce mowing speed and
open the rear discharge of the
cutting unit.
2) Check for any mechanical
interference and adjustment
within the cutting unit.
3) Swap cutting reel motors
between cutting units.
4) Replace cutting reel motor if
faulty.
5) Swap cutting unit position.
6) Inspect the cutting unit wiring.
7) Measure main harness
connectors P44 and P45 for 48
Vdc.

High Temperature
Warning –
Motor/Generator
Motor/Generator
controller
This fault is reported
when the temperature
inside the
motor/generator
exceeds the design
limit.
• When the temperature of
the motor/generator rises to
the over-temperature range,
the controller for the
motor/generator reduces
electrical current in relation
to the motor/generator
temperature. This could
result to a 48V system
undervoltage warning or
fault.
• If the absolute overtemp
value is reached, the cutting
reel motors are disabled and
the motor/generator stops
generating until the fault is
no longer active.
1) Make sure the hood screen is
clean.
2) Check that the air intake for the
motor/generator is not blocked.
3) Allow the machine to cool.
