4. Introduction
The GridScan/Pro is a very reliable SIL 2 certified safety
light curtain. It was developed and designed to safeguard
all types of industrial doors such as sectional or high-speed
doors. The system is ideal for door openings up to 10 m
wide and can handle door closure speed of 1.6 m/s. The
opening speed is up to 3 m/s. The emitter and receiver can
be installed directly into the guide rail (blanking version)
or to the front or the back of the door (static version).
Therefore, a blanking version as well as a static version
(without door blanking) are available.
The GridScan/Pro has a selectable output of Frequency
Safety Signal (FSS) or Push-Pull, so one system can handle
all relevant outputs. Selecting the FSS output allows
operation according to EN ISO 13849-1:2015 Cat. 2
without periodic testing of the light curtain. This output is
included in the TÜV certification of the GridScan/Pro.
