8.3 Beam blocker
Uncontrolled reflections of the laser beam can cause malfunctioning of the sensor or disturb people.
Therefore, a beam blocker should be fitted whenever possible to block the beam when there is no target
present. A beam blocker is a flat surface (at least 25mm x 25mm) made of any matte non-reflecting material.
It is mounted parallel to the sensor at any convenient distance.
The amber edge-LED must not light while the laser beam hits a beam blocker!
8.4 Retro-reflective foil (Part # FTDF 025F025)
Gaps in a lap stream can be clearly detected by a Scatec-10 / -15 if the retro-reflective foil (part number
FTDF 025F025, shipped with the sensor) is mounted as a beam blocker.
Certain false pulse suppression modes are based on a clear gap detection (for detailed explanation of these
modes, refer to section 9.2 Comments on the operational parameters.)
Correct mounting of the retro-reflective foil:
1.)
One side of the foil must be aligned parallel
line.
2.)
