In order to jointly install PHOTO 3 and PHOTO II, the po-
sition of the elements making up the photocell (TX-RX)
must comply with the warning indicated in the instruction
manual of the photocells.
4.4.1 FT210B PHOTOSENSOR
The FT210B photosensor combines in a single device a force limiting sys-
tem (type C, in accordance with the EN12453 standard) and a presence
sensor that detects obstacles on the line of sight between the TX transmit
-
ter and RX receiver (type D, in accordance with the EN12453 standard). In
the FT210B photosensor, the signals regarding the status of the sensitive
edge are sent through the photocell range, integrating the 2 systems in a
single device. The transmitting element located on the moving leaf is bat
-
tery-powered, which eliminates visually unpleasant connection systems;
special circuits reduce battery consumption, ensuring up to 15 years’ life
(see estimation details in the product’s instructions).
A single FT210B device combined with a sensitive edge (TCB65, for ex
-
ample) allows for attaining the level of safety of the “primary edge” required
by the EN12453 standard for all “types of use” and “types of activation”.
The FT210B photosensor combined with the “resistive” sensitive edges
(8.2 kΩ) is safe against faults (category 3 pursuant to the EN 13849-1
standard). It is equipped with a special anti-collision circuit to prevent inter
-
ference with other detectors, even not synchronised, and allows for adding
other photocells; for example, in case of transit of heavy vehicles, where a
second photocell is normally positioned 1 m above the ground.

mation on the connection and addressing methods.
