Leuze electronic MLC 530 - Timing Controlled Muting

Functions

Figure 4.4: Reduced resolution; several sufficiently small objects can move simultaneously in the pro-
tective field or be removed.
Reducing resolution
The “Reduced resolution” function is activated in operating mode 3/FG2 and is effective in the entire
protective field (see chapter 7.5).
4.8 Timing controlled muting
By means of muting, the protective function can be temporarily and properly suppressed, e.g. if objects
are to be transported through the protective field. The OSSDs remain in the ON state in spite of interruption
of one or more beams.
Muting is initiated automatically and via two mutually independent muting signals. These signals must be
active during the entire duration of the muting operation. Muting may not be initiated by a single sensor
signal, nor may it be fully initiated by software signals.

Objects in the protective field are not monitored for presence or number, i.e. sufficiently small
objects can be removed from the protective field and brought back to any blanked area without
the optical protective device reacting.
The “Reduced resolution” function can be combined with the “Fixed blanking” function (see
chapter 4.7.1) and is always activated together with the “Floating blanking” function (see
chapter 4.7.2).
