Blanking Overview
To use the blanking features, the transceiver must have either of these plug-
ins:
•
Catalog number 450L-APR-MU-8 – the muting/blanking plug-in
•
Catalog number 450L-APR-BL-5 – the blanking plug-in
The Bulletin 450L-E safety light curtain has three types of blanking:
•
Fixed blanking
•
Floating blanking
•
Reduced resolution blanking
Lens identification and zones help with the implementation of blanking.
Lens Identification
shows an example of the identification of the lenses for
both finger and hand resolution for a light curtain that has a 300 mm (11.81 in.)
height. Notice the following:
•
Lens 1 is the lens closest to the connection plug-in (not the cascading
plug-in). This arrangement is especially important for the hand
resolution as lens ‘n’ is not used.
•
Both resolutions have the name number of lenses.
•
The even-numbered lenses of hand resolution are not used; the lens ‘n’ is
not used.
•
The Bulletin 450L safety light curtain transceivers are built on 16 lens
segments; the number of lenses ‘n’ is a multiple of 16.
