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. Caution: · RUNAWAYS -- Some conditions could cause the vehicle to run out of control. Disconnect the motor, or jack up the vehicle, and get the drive wheels off the ground before attempting any work on the motor control circuitry. · HIGH CURRENT ARCS -- Electric vehicle batteries can supply very high power, and arcs can occur if they are short circuit. Always turn off the battery circuit before working on the motor control circuit. Wear safety glasses, and use properly insulated tools to prevent short circuit.

All RTN pins are internally connected. 2. Two PWR pins, J1-1 and J2-1, are internally connected. It's recommended to use J1-1 to supply peripherals like alarm and contactor. Twist peripheral wires with PWR is the preferred for EMC. 3. Kelly Ammeter positive connect to 5V power supply of controller, negative to J1-2. 4. Switch to ground is active. Open switch is inactive. Caution: · Do not apply power until you are certain the controller wiring is correct and has been double checked. Wiring faults will damage the controller. · Ensure that the B- wiring is securely and properly connected before applying power. · The preferred connection of the system contactor or circuit breaker is in series with the B+ line. · All contactors or circuit breakers in the B+ line must have precharge resistors across their contacts. Lack of even one of these precharge resistors may severely damage the controller at switch-on. 8 Kelly Full Bridge Permanent Magnet Motor DC Controller User's Manual 3.2.2 Standard Wiring of PM Motor Controller V 3.4 Figure 3: PM motor controller standard wiring 9 Kelly Full Bridge Permanent Magnet Motor DC Controller User's Manual V 3.4 Figure 4: 120V motor controller standard wiring 10 Kelly Full Bridge Permanent Magnet Motor DC Controller User's Manual V 3.4 3.2.3 Communication Port A RS232 port of controller is provided to communicate with host computer for calibration and configuration. Figure 5: standard RS232 interface 3.3 Installation Checklist Before operating the vehicle, complete the following checkout procedures. Use LED code as a reference as listed in Table 1. Caution: · Put the vehicle up on blocks to get the drive wheels off the ground before beginning these tests. · Do not allow anyone to stand directly in front of or behind the vehicle during the checkout. · Make sure the PWR switch and the brake is off · Use well-insulated tools. · Make sure the wire is connected correctly. · Turn the PWR switch on. The Green LED stay on steadily and Red LED turns off when the controller operates normally. If this does not happen, check continuity of the PWR and controller ground. · The fault code will be detected automatically at restart. · With the brake switch open, select a direction and operate the throttle. The motor should spin in the selected direction. Verify wiring or voltage and the fuse if it does not. The motor should run faster with increasing throttle. If not, refer to the Table 1 LED code, and correct the fault as determined by the fault code. · Take the vehicle off the blocks and drive it in a clear area. It should have smooth acceleration and good top speed. 11 Kelly Full Bridge Permanent Magnet Motor DC Controller User's Manual V 3.4 Chapter 4 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. 4.1 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. · Discharge the capacitors in the controller by connecting a load (such as a contactor coil, resistor or a horn) across the controllers B+ and B- terminals. · Remove any dirt or corrosion from the bus bar area. The controller should be wiped down 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. 4.2 Configuration You can configure the controller with a host computer through either an RS232 or USB port. · Use straight through RS232 cable or USB Converter provided by Kelly to connect to a host computer. Provide >18V (either J2 pin1 or J1 pin1) to PWR. Wire power supply return to any RTN pin. · Disconnect motor wiring from controller. · Do not connect B+, throttle and so on. The controller may display fault code in some conditions, but it doesn't affect programming or configuration. 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. 12 Kelly Full Bridge Permanent Magnet Motor DC Controller User's Manual V 3.4 Table 1: LED CODES Green LED Code LED Code Explanation Green Off No power or switched off Green On Normal operation Green & Red are both On Solution 1. Check if all wires are correct. 2. Check fuse and power supply. Thats great! You got solution! 1. Software still upgrading. 2. Supply voltage too low or battery too high 3. The controller is damaged. Contact Kelly about a warranty repair. Red LED Code 1,2 ¤ ¤¤ Over voltage error 1. Battery voltage is too high for the controller. Check battery volts and configuration. 2. Regeneration over-voltage. Controller will have cut back or stopped regen. 3. This only accurate to ± 2% upon Overvoltage setting. 1,3 ¤ ¤¤¤ Low voltage error 1. The controller will clear after 5 seconds if battery volts returns to normal. 2. Check battery volts & recharge if required. 1,4 ¤ ¤¤¤¤ Over temperature 1. Controller case temperature is above 90. warning Current will be limited. Reduce controller loading or switch Off until controller cools down. 2. Clean or improve heatsink or fan. 2,2 ¤¤ ¤¤ Internal volts fault 1. Measure that B+ & PWR are correct when measured to B- or RTN. 2. There may be excessive load on the +5V supply caused by too low a value of Regen or throttle potentiometers or incorrect wiring. 3. Controller is damaged. Contact Kelly about a warranty repair. 2,3 ¤¤ ¤¤¤ Over temperature The controller temperature has exceeded 100. The controller will be stopped but will restart when temperature falls below 80. 2,4 ¤¤ ¤¤¤¤ Throttle error at Throttle signal is higher than the preset ,,dead zone power-up at Power On. Fault clears when throttle is released. 13 Kelly Full Bridge Permanent Magnet Motor DC Controller User's Manual V 3.4 3,1 ¤¤¤ ¤ Frequent reset May be caused by over-voltage, bad motor intermittent earthing problem, bad wiring, etc. 3,2 ¤¤¤ ¤¤ Internal reset May be caused by some transient fault condition like a temporary over-current, momentarily high or low battery voltage. This can happen during normal operation. 3,3 ¤¤¤ ¤¤¤ Hall throttle is When the throttle is repaired, a restart will clear the open or fault. short-circuit 3,4 ¤¤¤ ¤¤¤¤ Non-zero throttle Controller wont allow a direction change unless the on direction throttle or speed is at zero. Fault clears when change throttle is released. 4,1 ¤¤¤¤ ¤ Regen or Start-up Motor drive is disabled if an over-voltage is over-voltage detected at start-up or during regen. The voltage threshold detection level is set during configuration. The max threshold is about 1.25 times of controller rated voltage. I.e. you may set threshold lower than 60V for 48V controller. 4, 3 ¤¤¤¤ ¤¤¤ Motor Motor temperature has exceeded the configured over-temperature maximum. The controller will shut down until the motor temperature cools down. The Red LED flashes once at power on as a confidence check and then normally stays Off. "1, 2" means the Red flashes once and after a second pause, flashes twice. The time between two flashes is 0.5 second. The pause time between multiple flash code groups is two seconds.
