Leuze electronic RSL 430 - Changeover of Five Field Pairs in Changeover Mode Overlapped Monitoring

Functions
Leuze electronic RSL 430 38
Using field pair changeover
You can configure and switch over the field pairs according to the different requirements. The field pairs are
changed over via the corresponding control inputs.
The rules for field pair changeover depend on the changeover mode and changeover time. The activated
field pair must correspond with the respective operating mode. The time of the field pair changeover must
correspond with the machine's risk assessment. You must take the lead time, braking distances, response
times and machine stopping times, e.g. influenced by overlapping protective fields, into account.
If the rules are not observed, the safety-related switching outputs switch off and a message is displayed
(see chapter 12 "Diagnostics and troubleshooting").
The following rules apply for the field pair changeover:
• The field pair changeover performed by the control system must agree with the safety sensor's configu-
ration. This configuration is specified with the configuration and diagnostics software (see chapter 9.4
"Configuring protective function").
• With field pair changeover to an occupied protective field, the safety sensor only switches off the
safety-related switching outputs after the set response time plus a synchronization time of 40ms.
NOTICE
Take the lead time into consideration!
Ä Take the lead time of the changeover time and response time into consideration before op-
erating the machine in its new operating situation.
5.7.1 Fixed selection of one field pair
If Fixed selection of one field pair is set as the mode for field pair activation, field pair A1.1 is monitored
irrespective of how the control inputs are connected.
5.7.2 Changeover of five field pairs in changeover mode Overlapped monitoring
Changeover mode Overlapped monitoring: This changeover mode is only permitted for up to five field
pairs.
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.5.5: 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.
