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 FSS Control Unit, 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".
