Input circuit is opened (e.g. light guard at S12 and S22 interrupted):
– Safety contacts 13-14/23-24/33-34 are opened redundantly, auxiliary contact 41-42
is closed.
– Status indicators "Output", "OSSD CH.1" and "OSSD CH.2" go out.
– A low signal is present at the semiconductor output Y36 (switch state of safety con-
tacts).
– A low signal is present at semiconductor output Y32 (ESPE state).
