(2)Over Volt: The max voltage of reporting this fault - Range 18~105
Controller will not operate when battery voltage is higher than the value so as to protect battery
and controller.
Suggestion: Set according to the practical situation.
By default,It is 90V for 72V controller.
Controller Rated voltage Under Voltage Range (V) Over Voltage Range(V)
60V 30~80 30~80
72V 30~90 30~90
Figure 4.1
(3)Current Percent: Phase Current Percent. Range: 20~100
Functional description: The max motor current is (The Value * Peak Current of the Controller).
Suggestion: Factory default is 100%.
(4)Battery Limit: Battery Limit Current, Limit the max value of Battery Current. Range: 20~100
Functional description: Set max battery current so as to protect battery. A lower value means a
lower battery output current and better protective effect. But excessively low value will affect
acceleration.
Suggestion: Factory default is 100%.
(5)Identification Angle: Please download the instruction to how to use Identification angle
function from the website.

finished.You can see 85 in the Identification Angle item again.And the controller will
blink error code.This is normal.Please reset the power supply again.Then everything will be
fine.The motor is ready to be drived by the KLS controller.
Range: 85 or 170,nothing else.
(6)TPS Low Err: Hall active pedal, if lower than the value, report the fault of TPS Type. Range:
0~20
(7)TPS High Err: Hall active pedal, if higher than the value, report the fault of TPS Type. Range:
80~100
As you may know,the output of hall throttle from Kelly is about from 0.86V to 4.2V.
Our controller will report 3.3 error code if the output of hall throttle is below 0.5V or above 4.5V
by default.
The controller will think the hall throttle is shorted or damaged if the output is beyond the range
from 0.5V to 4.5V.
