R/M/L 1.2
UNDER-VOLTAGE
CUTBACK
The battery voltage is too low
Check battery wires and
connections; Check fuse state
and main contact connections.
1. Normal operation. Fault shows that the
batteries need recharging. Controller is
performance limited at this voltage.
2. Battery parameters are misadjusted.
3. Non-controller system drain on battery.
4. Battery resistance too high.
5. Battery disconnected while driving.
R/M/L 1.3
OVERVOLTAGE CUT-
BACK
Check battery wires and
connections; Check fuse state
and main contact connections.
1. Normal operation. Fault shows that regen
braking currents elevated the battery voltage
during regen braking. Controller is
performance limited at this voltage.
2. Battery parameters are misadjusted.
3. Battery resistance too high for given regen
current.
4. Battery disconnected while regen braking.

CONTROLLER
SEVERE OVERTEMP
If machine is operating under
heavy load, reduce load with
lower speed blade until
temperature cools down.
Bring heatsink temperature below +85°C, and
cycle interlock or KSI.
R/M/L 1.5
MOTOR TEMP HOT
CUTBACK
If machine is operating under
heavy load, reduce load with
lower speed blade until
temperature cools down.
1. Motor temperature is at or above the
programmed Temperature Hot setting, and the
current is being cut back.
2. Motor Temperature Control Menu parameters
are mis-tuned.
3. If the application doesn’t use a motor ther-
mistor, Temp Compensation and Temp Cut-
back should be programmed Off.
R/M/L 2.1
THROTTLE
Throttle failure
1. Throttle pot wiper voltage too high.
2. Bring throttle pot wiper voltage below the
fault threshold.
3. Throttle type may be error

sequence.
Reapply inputs in correct sequence.

MAIN CONTACTOR
DID NOT CLOSE
Main contactor failure
1. Main contactor did not close.
2. Main contactor tips are oxidized, burned, or
not making good contact.
3. External load on capacitor bank (B+
connection terminal) that prevents capacitor
bank from charging.
4. Blown B+ fuse.
R/M/L 2.2
PRECHARGE FAILED Cycle KSI
1. Check wire connections to keyswitch.
2. Check the positive and negative poles of the
mower controller are shorted.
