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 controller‟s 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.
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.
Use 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
