4 Function description
The operating mode selector switch enables you to switch between 5 different operating
modes (operating modes OM1 ... OM4 and special operating mode OM5 (Service)).
For OM1 ... OM4, one button each is available. For the special operating mode (Service),
button OM1 must be operated for a certain period (see Monitoring of operating time [
50] ). Each button is assigned a monitored semiconductor output. Operating the button
changes the semiconductor output from a "0" signal to a "1" signal. The operating mode se­
lector switch guarantees that only one of the semiconductor outputs has a "1" signal at any
one time.
