Introduction to instructions and warnings
This manual is intended only for qualified technical staff
in charge with machine installation.
The information in this manual is not intended for the
final user.
This manual refers to the synchronized photocells
R90/ F2ES, G90/F2ES, G90/F2ESI, G90/F2ES/TRIX/TX and
G90/F2ES/TRIX/RX and must not be used for any other
product.
Read thoroughly this section before
installing the machine.
The installation must be performed
only by qualified technical personnel in
accordance with relevant legislation.
Perform connections with cables that
WARNINGS
are adequate to the current and voltage
requirements and comply with product specifications.
In order not to affect their proper functioning, the
photocells must operate without using reflections and must
not interfere with other photocells, whether they be of the
same or of different types. It is possible that interferences
occur between the pair of not-synchronized photocells
with tension 12/24V ac-dc , among more than two pairs
of synchronized photocells with tension 12/24Vac or with
other devices that emit infra-red light. Take all the necessary
precautions in order to eliminate this problem.
To better understand the issues related to reflection and
interference see figure 4.

Product description

The synchronized photocells versions R90/F2ES, G90/F2ES,
G90/F2ESI, G90/F2ES/TRIX/TX and G90/F2ES/TRIX/RX are
presence detectors based on infra-red technology, which
allow detecting obstacles on the optical axis between the
transmitter and receiver photocells; they can be used for
automatic entries, for courtesy services and monitoring
passageways.
Within these instructions, the transmitter photocell is
referred to as TX photocell, the receiver photocell is
referred to as the RX photocell, while one or more pairs of
photocells (always consisting of an RX and a TX photocell)
will be referred to as photocells.

Direct optical interpolation between the photocell TX and the photocell
RX with modulated infrared ray
12/24Vac 50Hz, 12/24Vdc
TX=19mA, RX=20mA
880 nm
<17°
Standard 10 m, option 15m obtained by cutting the connection E
positioned on the rear of the RX photocell circuit board. See fig. 3
Minimum operational distance of 0.8 m
Double relay with series connections (double safety), normally open
output (COM-NO) and normally closed output (COM-NC), 30Vmax
0.5Amax with resistive load
<30ms

R90/F2ES dimensions in mm. 62 x 88 x 27 Weight: 90g
G90/F2ES dimensions in mm. 75 x 77 x 29.2 Weight: 141g
G90/F2ESI dimensions in mm. 75 x 77 x 56.6(RX) 54.9(TX) Weight: 167g
G90/F2ES/TRIX/... dimensions in mm. 75 x 98 x 58 Weight: 283g
These photocells are intended for installation on fixing
surfaces flat and parallel to each other, which enable the
proper centring between the TX and the RX photocells.
Versions available:
• R90/F2ES and G90/F2ES for external fixing installation
• G90/F2ESI for installation inside 60mm diameter round
boxes
• G90/F2ES/TRIX/TX
installation with TRIX series columns.

Terminals and signalling
Terminals for photocell TX (see figure 1):
1 positive supply 24Vdc, supply 24Vac
2 negative supply 24Vdc, supply 24Vac
LED for TX signalling photocell (see figure 1):
PW turned on when supply voltage is present, if off,
indicates that the power supply is missing or is
incorrectly connected
Terminals for photocell RX (see figure 1):
1 positive supply 24Vdc, supply 24Vac
2 negative supply 24Vdc, supply 24Vac
3,4,5 OUTPUT. Normally closed contact (terminals 3-4)
with working photocells and no obstacles between
TX and RX. Normally open contact (terminals 4-5)
with working photocells and no obstacles between
TX and RX.
LED for RX signalling photocell (see figure 1):
L indicates the condition of the output contact, its
brightness is proportional to the received signal
strength, it turns off when there is an obstacle
between the photocells (contact open)
Selecting the supply voltage of the photocells 12/24V ac/dc
The photocells are always delivered prearranged for 24V
ac/dc power supply.
To power the photocells 12V ac/dc is necessary to short-
circuit by means of tin whiskers the pads C (see Figure 3)
at the rear of the printed circuit boards of the photocells.

Installation
Caution: before installing the photocells, check the
compatibility and technical specifications of the control
and G90/F2ES/TRIX/RX only
