MAIN DRIVER OFF
If the FET that controls the closing of the solenoid is not energized when it should be, a main driver off fault
is detected by the speed controller.
MAIN CONT DNC
The main cont dnc (main contactor (solenoid) did not close) fault is detected when the speed controller has
sent voltage to the solenoid activating coil but the solenoid contacts are not closed.
MAIN COIL FAULT
If the speed controller determines that the solenoid is not closing as a result of a solenoid coil failure, a main
coil fault is detected.
FIELD MISSING
If the speed controller is operating at a duty cycle of greater than 90% (almost full speed) and the field current
is less than 3 amps, a
field missing fault is detected by the speed controller.
HPD
The HPD (High Pedal Detect) fault is detected if the accelerator pedal is already depressed when the key
switch is turned to the ON position. This fault is also detected if the accelerator pedal is pressed when the
selected direction is changed by pressing the Forward/Reverse switch. This fault, when not caused by the
operator, can indicate that the pedal limit switch has failed closed.
PROC/WIRING
This fault is detected if the Forward/Reverse switch is giving a signal to place the controller in forward and
reverse at the same time. This rare fault can be caused by a failed switch or improper vehicle wiring.
OVERVOLTAGE
If the speed controller detects that the battery voltage is too high (68.4 to 75.6 volts DC), the overvoltage fault
is detected.
LOW BATTERY VOLTAGE
If the battery voltage falls below 34 volts ±5%, the low battery voltage fault is detected by the speed controller.
THERMAL CUTBACK
If the controller heatsink temperature is found to be in excess of 85 °C ±5 °C (185 °F ±41 °F) or below –25 °C
±5 °C (–13 °F ±34.3 °F), the
thermal cutback fault is detected.
MOTOR STALL
If the motor current is high and there is no movement of the vehicle wheels for a short period of time, a motor
stall is detected by the speed controller. This fault can be caused by an operator holding the vehicle on a hill
by depressing the accelerator pedal instead of the brake pedal.
