Connecting basic and expansion modules
EN
Connecting checkback contacts
The inputs of the modules must all be potential-free.
You may connect here any push buttons, sensors, switching tracks
or the potential-free outputs of switching decoders. For checkback
signals coming from the road use FALLER sensors, article number
161773.
TIP
NOTICE
Never connect to the inputs of the modules any live components such
as, for instance, the outputs of points decoders. This might destroy the
modules.

Connect one end of the sensor to the ground (0 V) and the other end
to the required input (E1 - E11), see Fig. 4.
