Chapter 2 Features and Specifications
2.1 General functions
(1) Extended fault detection and protection. The LED flashing pattern indicates the fault
sources.
(2) Monitoring battery voltage. It will stop driving if the battery voltage is too high and it will
progressively cut back motor drive power as battery voltage drops until it cuts out
altogether at the preset “Low Battery Voltage” setting.
(3) Built-in current loop and over current protection.
(4) Configurable motor temperature protection range.
(5) Current cutback at low temperature and high temperature to protect battery and controller.
The current begins to ramp down at 90℃ case temperature, shutting down at 100℃.
(6) The controller keeps monitoring battery recharging voltage during regenerative braking,
progressively cutting back current as battery voltage rises then cutting off regen altogether
when voltage goes too high.
(7) Maximum reverse speed is configurable to half of the maximum forward speed.
(8) An RS232 port allows for configuration, programming and software upgrades using the
free Windows GUI with your PC.
(9) Provision of a +5 volt output to supply various kinds of sensors, including Hall effect type.
(10) 3 switch inputs which are activated by connection to Ground. Default to throttle switch,
brake switch and reversing switch.
(11) 3 analog 0-5V inputs that default to throttle input, brake input and motor temperature input
(12) Pulsed reverse alarm output.
(13) Main contactor driver. Cutting off the power if any fault is detected.
(14) Current meter to display both drive and regen current. Save shunt!
(15) Configurable boost switch. Enables the maximum output power achievable if the switch is
turned on.
(16) Configurable economy switch. Limits the maximum current to half if the switch is turned on.
(17) Maximum reverse power is configurable to half power.
(18) Enhanced regen brake function. A novel ABS technique provides powerful and smooth
regen.
(19) Configurable 12V brake signal input, in lieu of motor temperature sensor.
(20) Optional joystick throttle. A bi-symmetrical 0-5V signal for both forward and reversing.
(21) Configurable motor over-temperature detection and protection with the recommended
thermistor KTY84-130.
(22) 3 hall position sensor inputs. Open collector, pull up provided.
(23) Optional supply voltage 8V-30V.
Caution! Regeneration has braking effect but does not replace the function of a mechanical
brake. A mechanical brake is required to stop your vehicle. Regen IS NOT a safety feature!
Controller may stop regen, without warning, to protect itself or the battery(it won’t protect you!).

Chapter 3 Wiring and Installation
3.1 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.
Height: 41 millimeters

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.
5.1 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.
16
Kelly KBS Brushless Motor Controller User’s Manual
•
•
•
V 4.1
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.
5.2 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-L user program can not work with KBS-X controller,vice versa.Only KBS-X requires
Kelly RS232 Converter to support the communication.
Download the free configuration software from:
http://www.kellycontroller.com/support.php
Caution:
• Make certain that the motor is disconnected before trying to run the Configuration
Software!
•Configuration software will be regularly updated and published on the website. Please
Update your Configuration Software regularly. You must uninstall the older version
before updating.
•When setting "Hall Sensor Type" in GUI, do not use "Auto-Check". This has been
deleted from the newer configuration software versions.
