±
2% upon Overvoltage
setting.

Low voltage error
1. The controller will clear after 5 seconds if battery
volts returns to normal.
2. Check battery volts & recharge if required.

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.

Motor did not start
Motor did not reach 25 electrical RPM within 2
seconds of start-up. Hall sensor or phase wiring
problem.

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.

¤¤¤
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
or short-circuit
When the throttle is repaired, a restart will clear the
fault.
3,4
¤¤¤ ¤¤¤¤
Non-zero throttle on
direction change
Controller won’t allow a direction change unless the
throttle or speed is at zero. Fault clears when throttle
is released.

Regen or Start-up
over-voltage
Motor drive is disabled if an over-voltage is detected
at start-up or during regen. The voltage threshold
detection level is set during configuration.

¤¤¤¤ ¤¤
Hall sensor error
1. Incorrect or loose wiring or a damaged hall sensor.
2. Also be caused by incorrect hall angle
configuration (60 degree or 120 degree)

over-temperature
Motor temperature has exceeded the configured
maximum. The controller will shut down until the
