operating
1. Check if all wires are correct.
2. Check fuse and power supply.
Green
On
Normal operation That’s great! You got solution!
1,2 ¤ ¤¤
Over voltage error
1. Battery voltage is higher than max operating
voltage of the controller. Please check the
battery voltage and configuration.
2. Over voltage at regeneration. Controller will cut
back or stop regeneration.
1,3 ¤ ¤¤¤
Low voltage error 1. The controller will attempt to clear the fault
code automatically after 5 second if battery
return to normal.
2. Check the battery voltage.
3. Charge battery if necessary.
1,4 ¤ ¤¤¤¤ Over temperature
warning 1. The controller temperature is over 90ºC. The
controller will cut back current in the case.
Stop or reduce output to ensure the
temperature fall.
2. Improve heat sink or airflow
2,1 ¤¤ ¤
Throttle sensor
fault
1. Check if the connecting is correct.
2. Check if the voltage is in 0-5V.
2,2 ¤¤ ¤¤
Internal voltage
fault
1. Check if the B+ and PWR voltage are correct,
refer to B- or RTN. Could be PWR voltage low.
2. Please check load on 5V supply. Could be high
load on 5V. Incorrect pot wiring can load it
heavily
。
1. The controller is damaged. Please contact
Kelly for warrantee.
2,3 ¤¤ ¤¤¤ Over temperature 1. The controller temperature is over 100ºC.
Controller stops driving in order to protect itself.
2. Stop driving and wait for temperature fall. The
controller will restart if temperature drops below
80ºC.
2,4 ¤¤ ¤¤¤¤
Throttle error at
power up
1. The throttle signal is higher than configured
dead zone at power-on
2. The fault will disappear if restart or release
throttle.
3,1 ¤¤¤ ¤ Frequent reset 1. The controller will stop driving after detect too
many resets.
2. Mostly because of B- or return wiring. Use
