Nice FT210 Anweisungen Und Hinweise Für Den Installateur Seite 4

Because the F210 photocells have a horizontal scope of 210° and a vertical scope of 30°, they can also be applied on uneven
surfaces where the correct alignment between TX and RX is not normally possible (see figure 2).

3) Installation
!
The system must be disconnected from the mains
power supply during installation. If buffer batteries are
present, these must also be disconnected.
3.1) Preliminary checks
Due to the peculiarity and uniqueness of the product, certain
aspects concerning the operating principles must be evalu-
ated before proceeding with the installation in order to ensure
maximum safety and functionality.
• Check carefully that the use parameters conform to the
data indicated in the "technical characteristics" chapter. If
in doubt, do not use the product and ask clarification from
the Nice technical assistance department.
• The transmitter continuously controls the status of the sen-
sitive edge and transmits the information to the receiver. In
order to reduce the consumption of the battery and main-
tain the required safety level, this operation is performed
with 2 different "speeds": SLOW when the gate is at a
standstill; FAST when the gate is moving. The transmitter
detects when the gate is moving through a special sensor
that detects the vibration of the moving gate. As soon as
the gate begins to move the transmitter switches to the
FAST mode and remains so until the gate is motionless for
10 or 90 seconds (see jumpers JP2 and JP3 in table 1).
• In order to guarantee the required safety level, the receiver
must detect the status of the gate, above all to verify if the
SLOW or FAST mode of the gate is correct.
This control mechanism occurs through the "PHOTOTEST"
input of the receiver (see connection examples in figures 18
and 19). A Phototest is normally performed in the control unit
at the beginning of each manoeuvre. In this way the receiv-
er of the FT210 is informed that the gate is about to move.
• If the control unit does not have Phototest the FT210 can
in any case be used by connecting the PHOTOTEST input
of the FT210 to the SCA (Gate open indicator) output of
the control unit. In this case a flashing signal should be
present on the SCA output during the entire duration of the
movement (see the connection example in figure 20).
• If the control unit does not even have an SCA output, the
FT210 should be programmed in the continuous FAST mode
by disconnecting the JP3 jumper on the TX (see table 1).
• In the control unit in which the beginning of the opening
manoeuvre and the automatic closure is performed, the
communication from the FAST mode to the SLOW mode
must be held for 90 seconds when the gate stops (see JP2
in table 1). In this way the TX remains in the FAST mode for
the entire opening time of the gate. The pause time of the
control unit must obviously be less than 90 seconds.

• FT210 has been designed not to interfere with and not to
be interfered with by other photocells, meaning that the
FT210 can be used along with other photocells. Function-
ing is guaranteed with at least one other couple of Nice
photocells whereas functioning may not be guaranteed
with more than one couple or photocells of another make.
To check that there are no effects caused by other devices,
carefully perform the testing procedure indicated in chap-
ter 4 and check the related signals in table 5.
Two FT210 devices can in any case be placed to control
the front and rear parts of the same gate, being that the
two TX transmit the signals in the opposite direction.
• Two FT210 devices cannot be positioned to control the
same area. If a receiver receives the signal of two transmit-
ters, it activates the "safety" mode and blocks the gate
movement. See the related signal in table 5.
Figure 3 illustrates an example of correct installation.
