7.4 Operating mode 2
The following functions can be selected via external wiring:
• Fixed blanking can be taught without size tolerance, see chapter 4.7.1 „Fixed blanking“.
• Linkage of electronic safety-related switching outputs possible, see chapter 4.6.2 „Linking of elec-
tronic safety-related switching outputs“.
• Linkage of contact-based safety-related switching outputs in addition to linkage of electronic safety-
related switching outputs possible, see chapter 4.6.1 „Contact-based safety circuit“.
• The functions listed can be combined (see table 7.6).
Permanent settings which cannot be changed by control signals:
• Internal start/restart interlock deactivated
• SingleScan selected
Table 7.6: Pin assignment operating mode 2
Teach blanking by opening the bridge between pin 1 and pin 4 with a teach key switch and ap-
plying a voltage of +24 V to pin 1 and a voltage of 0 V to pin 4 (see table 7.5).
