Functions
5.2.3 Two protective functions
In this function mode, you configure independent protective functions with all associated safety parameters
for safety-related switching outputs OSSD-A and OSSD-B.
• For each protective function you can define up to ten field pairs in one configuration bank.
• Field pair actuation and field pair changeover take place separately and independently for each config-
uration bank.
For the field pair changeover, see chapter 5.7 "Field pair changeover".
5.2.4 One protective function – four field mode
The safety sensor monitors one protective field and three warning fields.
Monitoring is performed together for the field pairs of protective function A and protective function B. If, for
example, the control system is monitoring field pair A1.1 for protective function A, field pair B1.1 for protec-
tive function B is also monitored.

Fig. 5.1: Four field mode
If the protective field of protective function A is violated, safety-related switching outputs OSSD-A switch.
If the protective field of protective function B is violated, the indication signal B-CLEAR is generated – the
safety-related switching outputs do not switch.
The signals are assigned to the switching outputs via the configuration and diagnostics software (CONFIG-
URATION > Outputs; see chapter 9 "Configuring the safety sensor").
