Green LED Code
LED Code Explanation
Solution
Green Off
No power or
switched off
1. Check if all wires are correct.
2. Check fuse and power supply.
Green On Normal operation That’s great! You got solution!
Green & Red are
both On
1. Software still upgrading.
2. Supply voltage too low or battery too high
3. The controller is damaged. Contact Kelly about a
warranty repair.
Red LED Code
LED Code Explanation Solution
1,2 ¤ ¤¤ Over voltage error 1. Battery voltage is too high for the controller.
Check battery volts and configuration.
2. Regeneration over-voltage. Controller will have
cut back or stopped regen.
3. 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.
2,2 ¤¤ ¤¤ Internal voltage
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
℃
.
2,4 ¤¤ ¤¤¤¤
Throttle error at
power-up
1. Throttle signal is higher than the preset ‘dead
zone’ at Power On. Fault clears when throttle is
