5. Overview
The emitter and receiver edges create a grid of infrared
beams offering up to 2.5 m (8.2 ft) in protection height.
When the infrared beams are interrupted, the output sends
a signal to the connected door controller. As soon as the
detection area is clear again, the output switches to indicate
that the area is “clear”. The blanking system is designed
to mount directly into the guide rails (GridScan/Mini-SB2).
As the door closes, the GridScan/Mini-SB2 recognizes the
door as such and does not switch the output.

CAUTION
Damage to the eye
Although the GridScan/Mini-SB2/-ST2 does
not emit dangerous amounts of infrared
light, long exposure to intense infrared light
sources can result in damage to the eyes.
Never look directly into the active
infrared emitter from a close distance.
Never scratch or paint the optical lenses because they
form the light path! Do not drill additional holes into
the profile. Unpack the profiles just before installation
in order to avoid damage.
Do not bend or twist the edges!
Oil can damage the cables. Contamination must be
avoided at all times!
Although the GridScan/Mini-SB2/-ST2 is insensitive
to direct sunlight, avoid all unnecessary exposure if
possible, most especially to the receiver.
Avoid interference from blinking lights or infrared light
sources such as photo cells or other light curtains.
Do not install the GridScan/Mini-SB2/-ST2 in places
where the emitter and receiver edges are directly
exposed to light sources such as FL tubes or energy
saving lamps.
