Note
An open input is interpreted as "low".
Terminal M2 must be connected so t
hat the digital inputs (DI0 ... DI3) can be used. This is
achieved through one of the following measures:
Provide the ground reference of the digital inputs.
A jumper to terminal M (this removes the electrical isolation for these digital inputs).
Note
A 24 V supply voltage must be connected to terminal X124 for the digital outputs to be used.
If momentary interruptions in the voltage occur in the 24
V supply, the digital outputs are
deactivated until the interruption has been rectified.
