Kelly’s programmable motor controllers provide efficient, smooth and quiet
controls for electric motorcycles, golf carts and go-carts, as well as
industrial motor speed or torque control.
It uses high power MOSFET’s and, PWM to achieve efficiencies of up to 99% in
most cases. A powerful microprocessor brings in comprehensive and precise
control to the controllers. It also allows users to adjust parameters, conduct
tests, and obtain diagnostic information quickly and easily.
Chapter 2 Features and Specifications
General functions
-
Extended fault detection and protection. The LED flashing pattern indicates the fault sources.
-

Chapter 3 Wiring and Installation
-
Mounting the Controller
The controller can be oriented in any position which should be as clean and dry as possible, and if necessary, shielded with a cover to protect it from water and contaminants.
To ensure full rated output power, the controller should be fastened to a clean, flat metal surface with four screws. Applying silicon grease or some other thermal conductive material to contact surface will enhance thermal performance.
Proper heat sinking and airflow are vital to achieve the full power capability of the controller.
The case outline and mounting holes’ dimensions are shown in Figure 1.

Chapter 5 Maintenance
There are no user-serviceable parts inside the controllers. Do not attempt to
open the controller as this will void your warranty. However, periodic,
exterior cleaning of the controller should be carried out.
The controller is a high powered device. When working with any battery powered
vehicle, proper safety precautions should be taken that include, but are not
limited to, proper training, wearing eye protection, avoidance of loose
clothing, hair and jewelry. Always use insulated tools.
Cleaning
Although the controller requires virtually no maintenance after properly
installation, the following minor maintenance is recommended in certain
applications.
- Remove power by disconnecting the battery, starting with battery positive.
- Discharge the capacitors in the controller by connecting a load (such as a contactor coil, resistor or a horn) across the controller’s B+ and B- terminals.
- Remove any dirt or corrosion from the bus bar area. The controller should be wiped with a moist rag. Make sure that the controller is dry before reconnecting the battery.
- Make sure the connections to the bus bars, if fitted, are tight. To avoid physically stressing the bus bars use two, well-insulated wrenches.
Configuration
You can configure the controller with a host computer through either an RS232
or USB port.
- Disconnect motor wiring from controller.
- Do not connect B+, throttle and so on. The controller may display fault code, but it doesn’t affect programming or configuration.
- Use a straight through RS232 cable or USB converter provided by Kelly to connect to a host computer. Provide >+18V to PWR(for a 24V controller, provide >+8V). Wire power supply return(supply negative) to any RTN pin.
- KBS-X user program can not work with KBS-L controller,vice versa.Only KBS-X requires Kelly RS232 Converter to support the communication.
