WARNING
Risk of injury from disabled safety devices during troubleshooting
When troubleshooting the kart, it might be necessary to temporarily switch on the kart
and/or disable safety devices or guards. There is thus a risk of inadvertent contact
with rotating or hot components, which can lead to serious injury.
a)
All tasks described below must be performed by authorised skilled workers.
b)
Before setting a part of the kart in motion, ensure that nobody is standing in the
danger area.
c)
Cordoning off the danger area.
The kart fails to start, or does not accelerate when the pedal is pushed down. Otherwise, it appears to work
properly. This problem might be caused by the drive sensor.
To check the drive sensor, measure the signal sent by the drive sensor to the controller, using a multimeter. To
identify the terminal for the measurement, refer to the pin assignment schedule and the wiring diagram. The
terminal can then be identified from the terminal assignment schedule. In our case, it is slot 7 at plug "Right
motor" or "Left motor" (drive potentiometer signal). If no voltage is measured when the gas pedal is pushed
down (normal voltage in this case: approx. 5 V), the cable to the drive sensor is faulty or the drive sensor is de-
fective.
7.2.3
Warning and fault signals at charger
If the kart cannot be charged and LED 4 is lit (red), proceed according to the checklist below.
–
Is the charging plug correctly plugged in?
–
Is the drive switch on?
–
Is charging enabled by the BMS?
–
Are the plugs and CAN bus lines correctly connected?
–
Are all CAN bus lines OK?
–
Is the charger powered through all three phases?
WARNING! High voltage! This check must be performed by a qualified electrician!
The charger fails to work properly, but none of the above checks revealed any problem.
a)
If you need assistance or if the charger is still not working properly, contact RiMO service department.
