High Temperature
Warning - Cutting
Unit 2
Cutting unit
This fault is reported when the
cutting unit controller
temperature exceeds 90 °C
(195 °F). When the 90 °C
threshold is reached, the fault
reports and the current being
sent to the motor is limited on a
linear basis until 100 °C (212 °F)
is reached. If either the motor
controller or the cutting unit
motor reach 100 °C, the cutting
unit is shut down. This fault is
not produced by a bad sensor.
If the fault continues to
occur at relatively low
loads, replace the
cutting unit electric
motor.
1) Let the machine cool.
2) Inspect the cutting unit to ensure
the reel spins freely, without
binding.
3) Reduce the reel speed.
4) Reduce the mowing speed.
5) If the fault is intermittent, check
the 48 Vdc ground to the motor.
