Note
Ensuring the function of digital inputs
An open input is interpreted as "low".
To enable the digital inputs (DI) to function, terminal M2 must b
e connected.
This is achieved through one of the following measures:
1.
Also route the reference ground of the digital inputs.
2.
A jumper to terminal M. (
Note:
This removes the electrical isolation for these digital
inputs.)
Note
If the 24 V supply is brief
ly interrupted, then the digital outputs are deactivated during this
time.
