Unfortunately I cannot have a SPDT switch to ground the signal when not pressed. Anyway finally I think I have solved using an extra external pulldown resistance of 10K.
I tryied to get direct support from Controllino, I had a first reply but I did not have any information related to internal resistence. The documentation has not information about this requirement and moreover has no information about the internal pulldown resistance value.
I’m really disappointed with the lack of documentation and of the support.
