9 Electrical System
9.1 Electronics Protection System
The vehicle's electronics are equipped with an overload-protection system.
If the motors are put under considerable strain for a longer period of time (for example, when
driving up a steep hill) and especially when the ambient temperature is high, then the electronic
system could overheat. In this case the vehicle's power is reduced gradually until it finally comes to
a halt. The Status Display shows a corresponding error code. By switching the power supply off
and back on again, the error code is cancelled and the electronics are switched back on. It will take
approximately five minutes until the electronics have cooled down enough for the motors to restore
full power again.
When the motors are stalled by an insurmountable obstacle, such as a high kerb, and the vehicle
driver allows the motors to strain against this hindrance for more than 20 seconds without moving,
then the electronics will automatically switch off to prevent the motors from being damaged. The
Status Display shows a corresponding error code. By switching off and back on again, the error
code is cancelled and the electronics are switched back on.
