5.2.3 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").
