9.1.4 FT210B photosensor
The FT210B photosensor combines in a single device a force
limiting system (type C, in accordance with the EN12453
standard) and a presence sensor that detects obstacles on the
line of sight between the TX transmitter 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 battery-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 example) 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 interference 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.

Consult the FT210B instruction manual for further
information on the connection and addressing
methods.
9.1.5 Gearmotor in SLAVE mode
The motor can function in SLAVE mode by suitably programming
and connecting it; this operating mode is used to automate two
opposite leaves that must move in a synchronised manner.
In this mode, a motor functions as MASTER, in other words, it
commands the manoeuvres, while the second motor functions
as SLAVE, executing the commands sent by the MASTER (all
the motors are MASTER by default).
The connection between MASTER and SLAVE is made via
BlueBUS.
m
In this case, the polarity of the connections between
the two motors must be observed, as illustrated in
“Figure 32” (the other devices will continue not
having polarity).
l
It is not important which motor functions as MASTER
or SLAVE; the choice must take into account the
ease of the connections and the fact that the “Step-
by-Step” command of the SLAVE device allows the
full opening of the SLAVE leaf only.
Perform the following operations to install two motors in MASTER
and SLAVE mode:
1. install the two motors
2. connect the two motors as shown in “Figure 32”
