Connection diagram
Connection of magnetic contact in Z-wiring:
It is not of importance which pair of cores is used as input or output.
To connect the contact, measure the short-circuited connection.
The end of line resistor R must always be attached to the final device of a detector group.
The outputs for the end position message (brown and grey) are "open collector" outputs with a
standard resistor of 10
. (high active, I_max = 50 mA)
