Not based on facts (only Siemens know) just a wild guess. Regards, Marcjan

Why i don't know, perhaps you can check attached manual, find out what pins are cut and then maybefind out why. Do you have a schematic of the installation , maybe there is a note on it. regards, Marcjan Attachment Signalbaugruppen_EN_en-US.pdf (72 Downloads)
