FCS modules
4. Operation overview
The modules are particularly designed for the use in vehicles
compatible to the Faller** car system. The modules FCS-1 to FCS-4 are
used in vehicles run with two accumulator batteries, the module FCS-L
in vehicles with one accumulator battery or, when reducing the module´s
input voltage, in vehicles run with two accumulator batteries, as well.
4.1. Voltage supply
The accumulator batteries mounted as a standard in the vehicles are
sufficient for the voltage supply.
FCS-1 to FCS-4
The voltage of 2,4 V that is provided by the vehicle accumulator
batteries, is doubled by the module. This enables white and blue LEDs
to be connected, which normally need a voltage of more than 2,4 V.
FCS-L
The circuit regulates the input voltage to a constant current of approx.
25 mA so that the appropriate voltage for the operation of the LEDs is
applied at the module´s output.
4.2. Possible connections
The modules FCS-1 to FCS-4 have 6 connections each, controlled by
specific software stored in the IC on the PCB. Depending on the
specification of the different versions, LEDs, dim switch, loudspeaker,
reed contacts and / or the vehicle´s motor can be connected. It is not
necessary to connect all outputs of the module.
The FCS-L has an output for the connection of red and white LEDs.
