Code
Explanation
Solution
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.

Reserved
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.
