NOTICE
Ensuring the function of the digital inputs
An open input is interpreted as "low".
Only "rapid inputs" can be used as inputs for BEROs and probes.
Terminals M1 or M2 must be connected for the digital inputs to work. 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.
