Leuze electronic RSL 420P - Changeover of Ten Field Pairs in Changeover Mode Fixed Changeover Moment

Functions
Leuze electronic GmbH + Co. KG RSL 420P 41
For an overview of the permissible function modes with changeover mode Overlapped monitoring, see
chapter 5.2 "Function modes of safety sensor".
The field pair changeover must take place within a configurable time period of the changeover time. Two
field pairs can be monitored simultaneously during the changeover time.
• First the control unit must switch to a new field pair before it switches off the previously active one.
• A maximum of two field pairs are active.
Each field pair is then only active if it is selected by the control unit.
• The changeover time starts when the second field pair is connected. When the changeover time has
expired, only one field pair should still be active.
• The changeover time is specified with the configuration and diagnostics software (see chapter 9.4.4
"Creating and configuring protective/warning field pairs").
Tab.5.4: Connection of control inputs F1 to F5 with activation of field pairs A1.1 to A1.5 for protective function A
Field pair Control input Description
F1 F2 F3 F4 F5
A1.1 1 0 0 0 0 Field pair A1.1 is active
A1.2 0 1 0 0 0 Field pair A1.2 is active
A1.3 0 0 1 0 0 Field pair A1.3 is active
A1.4 0 0 0 1 0 Field pair A1.4 is active
A1.5 0 0 0 0 1 Field pair A1.5 is active
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 B1.5 for protective function B.

5.7.3 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.
