Cleaning
It is recommended that the controller be kept clean and dry and that its fault histo-
ry file be checked and cleared periodically.
Periodically cleaning the controller exterior will help protect it against corrosion
and possible electrical control problems created by dirt, grime, and chemicals that
are part of the operating environment and that normally exist in battery-powered
systems.
Use the following cleaning procedure for routine maintenance:
1. Turn the power key to the OFF position.
2. Remove power by disconnecting the battery.
3. Discharge the capacitors in the controller by connecting a load (such as a
contactor coil) across the controller’s B+ and B- terminals.
4. Remove any dirt or corrosion from the connector areas. The controller
should be wiped clean with moist rag. Dry it before reconnecting the bat-
tery. The controller should not be cleaned with pressured water flow from
either a standard hose or a power washer.
5. Make sure the connections are tight, but do not over-tighten them.
Fault History File
The handheld programmer (to be ordered separately) can be used to access the
controller’s fault history file. The programmer will read out all the faults the con-
troller has experienced since the last time the history file was cleared. Faults such
as contactor faults may be the result of loose wires; contractor wiring should be
carefully checked. Faults such as overheating may be caused by operator habits or
by overloading.
After a problem has been diagnosed and corrected, it is a good idea to clear the
fault history file. This allows the controller to accumulate a new file of faults. By
checking the new history file at a later date, you can readily determine whether the
problem was indeed fixed.
When checking problems according the flashing of the STATUS light on the top of
the controller, refer to the details mentioned in our service manual which is avail-
able separately.
Contact your local dealer or a qualified electrician to work on the problems related
to the motor, controller or electrical system of the vehicle when you are not able to
fix them.
