1,1
¤
¤
Automatic error
identification
1. Wrong wiring of motor phase line or hall.
Please suspend the motor when enable
Auto-Identify function.
1,2
¤
¤¤
Over voltage error
2. Battery voltage is too high for the controller.
Check battery volts and configuration.
3. Regeneration over-voltage. Controller will have
cut back or stopped regen.
4. This only accurate to
±
2% upon Overvoltage
setting.
1,3
¤
¤¤¤
Low voltage error
1. The controller will clear after 5 seconds if battery
volts returns to normal.
2. Check battery volts & recharge if required.
1,4
¤
¤¤¤¤
Over temperature
warning
1. Controller case temperature is above 90
℃
.
Current will be limited. Reduce controller loading
or switch Off until controller cools down.
2. Clean or improve heatsink or fan.
2,1
¤¤
¤
Motor did not start
Motor did not reach 25 electrical RPM within 2
seconds of start-up. Hall sensor or phase wiring
problem.
2,2
¤¤
¤¤
Internal volts fault
1. Measure that B+ & PWR are correct when
measured to B- or RTN.
2. There may be excessive load on the +5V supply
caused by too low a value of Regen or throttle
potentiometers or incorrect wiring.
3. Controller is damaged. Contact Kelly about a
warranty repair.
2,3
¤¤
¤¤¤
Over temperature
The controller temperature has exceeded 100
℃
. The
controller will be stopped but will restart when
temperature falls below 80
℃
.

¤¤¤¤
Throttle error at
power-up
Throttle signal is higher than the preset ‘dead zone’ at
Power On. Fault clears when throttle is released.
3,1
¤¤¤ ¤
Frequent reset
May be caused by over-voltage, bad motor
intermittent earthing problem, bad wiring, etc.
3,2
¤¤¤ ¤¤
Internal reset
May be caused by some transient fault condition like
a temporary over-current, momentarily high or low
battery voltage. This can happen during normal
operation.
3,3
¤¤¤ ¤¤¤
Hall throttle is open
When the throttle is repaired, a restart will clear the
