8. Check list for troubleshooting


Parts are getting very hot and/or start to smoke.
Disconnect the system from the mains immediately!
!
Possible cause: The connections to the power supply are connected
the wrong round. à Check the connection. In this case the module
is probably damaged irreparably.

The LEDs do not light / flash.
Possible cause: The LEDs are connected the wrong round. à Check
the connections.
Possible cause: The power supply is interrupted. à Check the
connections.

FCS-L: After applying the supply voltage the LEDs flash quickly and
then go out.
Possible cause: The supply voltage is higher than 1,8 V. à Reduce
the input voltage, for instance by mounting a diode in the lead-in
wire from the power supply to the module.

FCS-L: The red or the white LEDs light brighter than the others.
Possible cause: The burning voltage of the red and the white LEDs
differs considerably. à Connect a series resistor (value from 1 to
20 W) to the LEDs that light brighter.

FCS-2 to -4: The vehicle does not drive.
Possible cause: The wrong connecting point at side B of the existing
reed contact was used. à Check the connection.

FCS-2 to -4: The vehicle drives backwards.
Possible cause: The connections of the motor are connected reverse.
à Check the connections.
