Stop Input; Ft210B Photo-Sensor - Nice RUN1800 Instrucciones Y Advertencias Para La Instalación Y El Uso

7.3.2) STOP input

STOP is the input that causes the immediate interruption of the
manoeuvre (with a short reverse run). Devices with output featuring
normally open "NO" contacts and devices with normally closed "NC"
contacts, as well as devices with 8,2kΩ constant resistance output,
such as sensitive edges, can be connected to this input.
During the self-learning stage the control unit, as in the case of Blue-
BUS, recognizes the type of device connected to the STOP input
(see paragraph 7.3.6 "Self-learning Other Devices"); subsequently
it commands a STOP whenever a change occurs in the recognized
status.
Multiple devices, even of different type, can be connected to the
STOP input if suitable arrangements are made:
• Any number of NO devices can be connected to each other in
parallel.
• Any number of NC devices can be connected to each other in
series.
7.3.3) Photocells
By means of addressing using special jumpers, the "BlueBUS"
system enables the user to make the control unit recognise the
photocells and assign them with a correct detection function. The
addressing procedure must be performed both on TX and RX (set-
ting the jumpers in the same way) making sure there are no other
pairs of photocells with the same address.
In an automation for sliding gates, RUN enables installation of the
photocells as shown in Figure 24.
Each time a photocell is added or removed the control unit must go
through the self-learning process; see paragraph 7.3.6 "Self-learning
Other Devices".

7.3.4) FT210B Photo-sensor

The FT210B photo-sensor combines a force limiting device (type C
in accordance with the standard EN1245) and a presence detector
which detects the presence of obstacles on an optical axis between
the TX transmitter and the RX receiver (type D in accordance with the
standard EN12453). The sensitive edge status signals on the FT210
photo-sensor are transmitted by means of the photocell beam, inte-
grating the two systems in a single device. The transmitting part is
positioned on the mobile leaf and is powered by a battery thereby
eliminating unsightly connection systems; the consumption of the
battery is reduced by special circuits guaranteeing a duration of up
to 15 years (see the estimation details in the product instructions).
By combining a FT210B device with a sensitive edge (TCB65 for
example) the level of security of the "primary edge", required by the
EN12453 standard for all "types of use" and "types of activation",
can be attained.
• Two devices with 8.2KΩ constant resistance output can be con-
nected in parallel; if necessary, multiple devices must be con-
nected "in cascade" with a single 8.2KΩ termination resistance.
• It is possible to combine Normally Open and Normally Closed by
making 2 contacts in parallel with the warning to place an 8.2KΩ
resistance in series with the Normally Closed contact (this also
makes it possible to combine 3 devices: Normally Open, Normally
Closed and 8,2kΩ).
!
If the STOP input is used to connect devices with safety
functions, only the devices with 8,2kΩ constant resistance
output guarantee the fail-safe category 3 according to EN
standard 954-1.

In the case of the installation of PHOTO 3 and PHOTO II together,
the position of the photocell elements (TX-RX) must comply with the
provisions contained in the photocell instruction manual
The FT210B is safe against individual faults when combined to a
"resistive" type (8,2Kohm) sensitive edge. It features a special anti-
collision circuit that prevents interference with other detectors, even
if not synchronised, and allows additional photocells to be fitted; for
example, in cases where there is a passage of heavy vehicles and a
second photocell is normally placed at 1 m from the ground.
See the FT210B instruction manual for further information concer-
ning connection and addressing methods.
