FCS modules
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.
