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)

¤¤¤¤ ¤¤¤
Motor
over-temperature
Motor temperature has exceeded the configured
maximum. The controller will shut down until the
motor temperature cools down.
The Red LED flashes once at power on as a confidence check and then normally stays
Off. “1, 2” means the Red flashes once and after a second pause, flashes twice. The pause
time between multiple flash code groups is two seconds.
