Switching Inputs
Light source off, Zero-point inputs are, for example, connected through relay contacts or
transistors (optocouplers).
Activate the light source switch-off in the relevant menu!
All GND signals are connected together internally and with the minus pole (GND) of the
24 V supply voltage.
