Leuze electronic MLC 530 61
FG2, fixed blanking can be activated, DoubleScan is pre-set and permanent and there is an option of inte-
grating a contact-based safety circuit.
• Fixed blanking, see chapter 4.7.1 „Fixed blanking“
• Floating blanking (see chapter 4.7.2 „Floating blanking“) as well as the combination of fixed and
floating blanking (see table 7.7)
• SingleScan, DoubleScan can be selected, see chapter 4.5 „Scan mode“
• Integration of contact-based safety circuit possible, see chapter 4.6.1 „Contact-based safety circuit“
• Reduced resolution (reduction by 1 beam) possible, see chapter 4.7.4 „Reduced resolution“
Permanent settings which cannot be changed by control signals:
• Internal start/restart interlock deactivated
Table 7.7: Operating mode 3 pin assignment with both FG1 and FG2 function groups
Teach blanking by opening the bridge between pin 1 and pin 3 with a teach key switch and ap-
plying a voltage of +24 V to pin 1 and a voltage of 0 V to pin 3 (see table 7.5).
Pin FG1: fixed and float-
ing blanking as well
as reduced resolution
