Note
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 coupled-motion reference ground of the digital inputs, or provide a jumper to
terminal M. (Notice! This removes the galvanic isolation for these digital inputs.)
