Locomotive decoders of the series 30 plus English
earth. It is possible to connect reed contacts or Hall sensors, for
example, which make contact to earth when getting into the magnetic
field of a permanent magnet.
You can switch the switching inputs respective to the decoder mass as
an alternative. In this case you have to solder a resistor (3,3 kOhm)
into the connection between switching input and earth of the rails.
Connect the reed contacts to the switching inputs and an earth
connection of the decoder. Reed contacts are not polarized, you can
assign the two contacts voluntarily.
When connecting Hall sensors check for the correct polarity. Connect
the earth connection of the Hall sensor to an earth connection of the
decoder, the connection for the voltage supply to a voltage output of
the decoder and the output to one of the switching inputs.
When exchanging the earth connection for the connection of the
voltage supply, the Hall sensor can be damaged!

Assigning the connections when using the SUSI interface:
SUSI PLUS Supply voltage for reed contacts or Hall sensors
SUSI CLOCK Switching input IN1
SUSI DATA Switching input IN2
SUSI GND Earth connection for reed contacts or Hall sensors
