Introduction to the instructions and warnings
This manual is intended only for professionally
qualified installers.
No information included in this document can be
considered interest for the end-user.
This manual refers to the synchronized photocells
M90/F2ES and M90/F2ESO and must not be used
for any other product.
Read carefully the instructions before installing.
The installation must be performed only by technical
qualified staff according to the regulations in force.
Make connections with cables appropriate for the
current required and respect the technical features
of the product.
The photocells must work without exploiting reflexes
and without interfere with other photocells, because
they might seriously prejudice correct functioning.
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 12/24V AC or
with other devices that emit infrared light. Follow all
the precautions to avoid this problem.
To understand the problems of the interferences
and the reflexes see

Product description
The synchronized photocells
M90/F2ES
and
M90/F2ESO
are obstacle detectors with infrared
technology, that permits to detect obstacles
positioned on the optical axis of the transmitter
photocell and the receiver photocell. They can be
used for automatic entrances, courtesy services
and monitoring steps. In this instruction the
transmitter photocell is called photocell TX, the
receiver photocell is called photocell RX and one
or more pairs of photocells (always composed by
one photocell RX and one photocell TX) are called
“photocells”.
Available versions:
–
Fixed version
M90/F2ES
ideal for installations
with fixing surfaces that are linear and parallel to
each other, and that permit a correct centering
of the photocells.
–
Adjustable version
M90/F2ESO
(210° along
horizontal axis and 15° along vertical axis) ideal
for installations with fixing surfaces that are not
parallel to each other, therefore the adjustable
system allows to create a correct centering
between the photocells.
