3. 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 Discharge the capacitors in the controller by connecting load such as a contactor coil or a horn across the controller s B and B terminals e Remove any dirt or corrosion from the bus bar area The controller should be wiped with a moist rag Be sure it is dry before reconnecting the battery e sure the connections to the bus bars are tight Use two wrenches for this task in order to avoid stressing the bus bars the wrenches should be well insulated 4 2 Configuration You can configure the controller with a host computer through RS232 e Use a standard RS232 cable connecting the 9pin connector on face penal to a host computer The cable should be straight Provide 8V to 30V supply to PWR either J2 pin1 or J1 pin14 Wire power supply ground to any GND pin Do not connect B throttle and so on The controller may display fault code but it doesn t affect programming or configuration Page 15 Kelly KDHB High Power Series PM Motor Controller User s Manual V 2 9 Table 1 LED CODES LED Code Explanation Solution Green No power or not 1 Check if all wires are correct Off operating 2 Check fuse and power supply Green
