Changeover of ten field pairs in changeover mode Fixed changeover moment
Changeover mode Fixed changeover moment: The field pair changeover must take place within the con-
figurable changeover time, i.e. after the changeover time has expired, a valid and stable input connection
must be present. The old field pair is monitored during the changeover time.
• The previously active field pair is monitored during the changeover time.
• The changeover time starts when the safety sensor registers a change at control inputs F1 to F5. When
the changeover time has expired, only one field pair should still be active.
• Monitoring of the newly activated field pair starts when the changeover time has expired.
• The changeover time is specified with the configuration and diagnostics software (see chapter 9.4.4
"Creating and configuring protective/warning field pairs").

In the case of two protective functions, connection of control inputs F6 to F10 applies analogously for acti-
vation of field pairs B1.1 to B1.10 for protective function B.
