7.9.5 Reduced resolution
Reduced resolution represents a particular type of floating blanking, in which multiple objects
can each interrupt a certain number of beams, while the light curtain remains in normal
operating mode.
The number below indicates how many adjacent beams the object can interrupt to guarantee
that the light curtain remains in normal operating mode. With reduced resolution 2, for
example, the object can interrupt 1 beam, 2 beams or no beam at all and the light curtain
remains in normal operating mode.
This function can only be set via ACM.
NOTE: This function affects the light curtain’s actual resolution and the user
is informed of this fact via a message.
Please note that the actual resolution changes when using this function.
Ensure that the minimum distance has to be recalculated and that the
installation of the light curtain must be adapted accordingly.
7.9.6 Tolerance
There are two types of tolerance: position tolerance and dimension tolerance.
• Position tolerance
Indicates the number of beams in the blanking zone that can be interrupted above and
below the blanking zone, without causing the OSSD to switch off.
If heavy vibration is present, this function is useful to avoid the OSSD changing state.
• Dimension tolerance
Indicates the number of beams by which the object may be smaller in comparison with the
number defined by the dimension value. It is a negative figure.
It is useful if an object interrupts half a lens. In this case, even minimum vibration could
cause the OSSD to change state.
The tolerance can be set in BCM and also in ACM.
To select this function via ACM, the user must have at least one blanking zone. Then he can
select either position tolerance or dimension tolerance. The tables below show various cases
in a blanking zone consisting of 3 beams.
