Function description

There is a high signal or a low signal at the safety outputs, depending on the position of the

actuator and the state of the inputs. The signal output Y32 signals the position of the actua-

tor.

State of the inputs and outputs:

The outputs cannot be switched back on until there is a low signal at both inputs simultane-

ously.

Safety inputs S11 and S21 are monitored for feasibility. A high signal can be present at the

inputs at offset times; the low signal must be present at both inputs simultaneously (partial

operation lock).
