2. Check fuse and power supply.
Green On
Normal operation
That’s great! You got solution!
Green and Red LED
Keep On
1. Software is upgrading.
2. Supply voltage too low or battery too high
3. The controller is damaged. Please contact Kelly
for warrantee.

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.
3. Please note there could be 2% error with
Overvoltage setting.

Low voltage error
1. The controller will attempt to clear the fault
code automatically after 5 second if battery
voltage returns to normal.
2. Check the battery voltage.
3. Charge battery if necessary.

Over temperature
warning
1.
The controller temperature is over 90
℃
. The
controller will cut back current in the case.
Stop
or
reduce
output
to
ensure
the
temperature fall.
2.
Improve heat sink or airflow

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.

Over temperature
1. When controller’s temperature is over 100
℃
. it
will stop driving in order to protect itself.
2. Stop driving and wait for temperature fall. The
controller will restart if temperature drops below
