LED Code Explanation
Solution
Off
No power or
switched off
1. Check if all wires are correct.
2. Check fuse and power supply switch.
On
Normal operating
That’s great! You got solution!
1,2 ¤ ¤¤ Over voltage error 1. Battery voltage is too high for the controller.
Check battery volts and configuration.
2. The controller will clear after 5 seconds if battery
volts returns to normal.
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 ¤ ¤¤¤¤
Temperature
warning error
1.
Controller case temperature is above 90
℃.
2.
Current will be limited. Release or reduce throttle
until controller cools down.
2,1 ¤¤ ¤
Throttle sensor
fault
1.
Check if all wires are correct.
2.
Check if the throttle type is correct.
3.
Check if the voltage is above 5V when use 0-5V
hall throttle.
4.
Check if connects to the right panel, conforming
to configured throttle type.
2,2 ¤¤ ¤¤ Internal volts fault 1. Measure that B+ & PWR are correct
2. There may be excessive load on the +5V supply.
3. Controller is damaged. Contact Kelly about a
warranty repair.
2,3 ¤¤ ¤¤¤
Over temperature
error
The controller temperature has exceeded 100
℃
. The
controller will be stopped but will restart when
temperature falls below 80
℃
.
2,4 ¤¤ ¤¤¤¤
Throttle error at
power-on
Throttle signal is higher than the preset ‘dead zone’ at
Power On. Fault clears when throttle is released.
3,1 ¤¤¤ ¤
Frequent reset
Fault clears after the restart.
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.
The LED flashes once at power on as a confidence check and then stays on for
normal operation. “1, 2” means it flashed once and after 0.5 second pause, flashes twice.
The time between two flashes is 0.25 second. The pause time between multiple flash
code groups is 1 second.
