Chapter 4 Programmable Parameters
KLS Configuration program allow users to set parameters according to the vehicle actual
working environment so as to be at its best.
The default parameters of the controller are not recommended for all applications. Make
sure set the proper parameters before making any test to avoid danger.
Customers can do program on PC software or Android App. The Android Tablet is preferred.
First of all, people need to do Identification angle function for KLS controller before running the
motor. The controller needs to be connected to batteries, motor and throttle before Identification
operation. That is to say, it is not enough to connect only power supply(PWR=pin7) to batteries
for Identification Angle operation.
Please download the instruction how to use Identification angle function from our website.

4.1 Step 1
(1)Low Volt: The min voltage of reporting this fault - Range 18~86, depending on model.
Controller will not operate when battery voltage is near the value so as to protect battery.
Suggestion: Set according to the practical situation. By default, it is set at 18V.
(2)Over Volt: The max voltage of reporting this fault - Range 18~86, depending on model.
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 60V for 48V controller. It is 80V for 60V controller. It is 86V for 72V controller.
