3.2 Drive controller
3.2.1 Maintenance
► The controller has no user repair accessories. Do not
attempt to open, repair, or otherwise change the controller.
This will damage the control and invalidate the warranty.
► It is recommended to regularly keep the controller clean
and dry, and regularly check and clear diagnostic history files.
► Regular cleaning of the outside of the controller can help
prevent corrosion or other electrical control failures caused by
dirt, dust, and chemicals, which are part of the environment
and often occur in battery powered systems.
► Before operating a battery powered vehicle, pay attention
to safety. These include but are not limited to: proper training,
wearing protective goggles, and avoiding loose clothing and
jewelry.
► Follow the cleaning steps below to carry out the maintenance process. Never use a
high-pressure flushing machine to clean the controller.
– Remove the battery to power off.
– By connecting a load (such as a contactor coil or horn) between controller B+and B -,
discharge the capacitor inside the controller.
– Remove dirt or corrosion at the power and signal terminals. Wipe the controller with a damp
cloth and dry it before connecting the battery. control
– The controller cannot be subjected to the impact of pressurized water flow.
– Make sure the wiring is correct and tightened.
