Description
Pair of 50 cm posts equipped with two additional
P.BY photocells, to be installed inside the premises
and covering the gates’ operating range.
The control station includes two separate con-
nections to be used according to the photocell’s
position:
PHOT C: The photocell works only when the gates
are being closed.
PHOT: The photocell works both when the gates are
being opened or closed.
This type of operation allows vehicles to enter even
when the gates are not yet completely open, provided
the operating range is free of obstacles.
(4.2x25) supplied.
7)
Pass the connection cable through.
8)
Secure the post to the ground using three of the
six screws (5.5x45) supplied, with their respective
expansion sleeves and washers.
9)
Fasten the base of the photocell to the post using
two of the four self-tapping screws (TCIC 3.5x13)
supplied.
10)
Connect the TX and RX to the control station as
shown in the general wiring diagram.
The TX requires only a connection for the power
supply provided by the 24 V output on the control
station. Be sure to respect the polarities (+/-).
The RX requires a connection for the 24 V power
supply (respect the pola/-) and a connection
for the NC contact on the PHOT C input.
11)
Put the photocell covers back on. The cover
with the lens must be placed on the receiver (RX - 4
terminals). The lens is identifi ed by the concentric
circles that can be seen when viewing the cover
against the light (Fig. 11a).
12)
Slip the plastic cover on the post top.

Installation (fi gures on page 7)
1)
Open the photocells by introducing a screwdriver
in the slit and using it as a lever.
2)
The difference between the receiver and the
transmitter is evident from the number of terminals
on the circuit boards:
4 terminals for the receiver (RX)
2 terminals for the transmitter (TX)
3)
Make holes on the back of the photocell where
indicated.
4)
Using the back of the photocell as a template,
mark the drilling points on the posts (the hole close
to the terminal board is for the cables). Do not leave
a space between the top of the photocell and the
top of the post.
5)
Drill two Ø 3 mm holes for the screws that secure
the photocell to the post and one Ø 10 mm hole for
the cables to pass through.
6)
Fasten the plate to the base of the post using
four of the eight countersunk self-tapping screws
