GridScan/Mini-SR

4. Introduction

The GridScan/Mini-SR is a very compact, Cat. 2 certified
light curtain designed for safeguarding the entrance area
of a freight or platform elevator. The GridScan/Mini-SR
comes in combination with a Safety Unit FSS, which can
be supplied with either 24 VDC or 230 VAC and features
a relay output.
Due to an integrated automatic range setting, the
GridScan/Mini-SR can also be mounted near shiny
surfaces without any mirroring.
The emitter and receiver edge have to be mounted at the
door frame and are synchronized electrically. This leads to
increased robustness against other light sources.
The emitter and receiver edge create a dense grid of
straight and crossed infrared beams offering 1,805 mm
(6 ft) protection height. When the infrared beams are
interrupted, the output sends a signal to the connected
elevator door controller. As soon as the detection area is
clear again, the output switches to indicate that the area
is "clear".

General instructions and precautions

 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!
Rx Tx
 Although the GridScan/Mini-SR 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-SR in places where
the emitter and receiver edges are directly exposed to
light sources such as FL tubes or energy saving lamps.
