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.
•
Discharge the capacitors in the controller by connecting a load (such as a contactor coil 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 either an through RS232.
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 a straight through RS232 cable or Kelly USB To RS232 Converter to connect to a host
computer. Provide 10V-30V (either J2 pin1 or J1 pin1) to PWR. Wire power supply return to
any RTN pin, isolated from B-.
