NOTICE
Ensuring the function of the digital inputs
An open input is interpreted as "low".
The "rapid inputs" can be used for position detection and as inputs of probes depending on the
associated terminal assignment.
To enable digital inputs 0 to 3 to function, terminal G1 must be connected. This can be done as
follows:
• Connect the ground reference of the digital inputs.
• A jumper to terminal M (note that these digital inputs are then no longer electrically
isolated).
Note
For a transient (brief) voltage interruption of the 24 V supply, the digital outputs are switched
inactive for this time.
