SC2-2 connections
Terminals are used to connect the light barriers, inputs and outputs and the voltage supply. Four terminals
are combined to form each terminal block. These terminal blocks can be disconnected, thus making it easy
to switch devices.
A light barrier channel that is not in use is jumpered (see section 5.1)
