High Temperature
Warning –
Starter/Generator
Starter/Generator
This fault is reported when the
starter/generator controller
temperature exceeds the design
limit set point. When the
overtemp region is entered,
motor current is limited on a
linear basis until the absolute
overtemp value is reached. This
fault is not produced by a bad
sensor.
Once current becomes
limited, the
starter/generator
motor output power
will be limited. This
could result to a 48
Vdc system
undervoltage warning
or fault. In both
instances, the Master
TEC will cut the PTO
and the operator will
not be able to mow
until the batteries have
recovered.
1) Clean the air intake screen of
the starter/generator.
2) Reduce the reel speed.
3) Reduce the mowing speed.

Motor Speed Stall -
CU1
Cutting unit
This fault is reported when the
cutting unit is active, yet remains
at zero rpm for more than three
seconds.
Swap motors between
cutting units to test the
motor. If the fault
follows the motor,
replace the motor. If
the fault stays with the
cutting unit, inspect
the cutting unit for
binding.
1) Check cutting unit 1 for any
debris clogging the reel.
2) Check the bedknife adjustment
of cutting unit 1.
3) Check to see if the motor can
spin without a load.
