maintenance the following checks should be made: Correct alignment, sealing, cleanliness of the lenses and internal components.
Any remedial work should be carried out as required.
If the FT12/FT20-AV photocell is to be taken out of service, this work must only be undertaken by authorised, qualified personnel.

SYNCRONIZATION
The photoelectric barrier FT12/FT20-AV has been projected for applications
in which it is necessary to apply two overlapping photocells, avoiding that they
go in collision one with the other. To get such result it is sufficiant to power
supply the photocells with 12/24 V~ and to cross the power supply. (Ex. When
the TX and RX of a photocell are power supplied with a black cable around 0
V~ and with a red cable of 24V~, the TX and the RX of the other photocell will
have to have the red cable with 0 V~ and the black cable around 24V~.)

The fixing screw (A)
positioned on the front hole
allows alignment only on
the horizontal axis (± 90 °)
Back hole
The screw (A) located on
the back hole allows the
perpendicular orientat
of ± 5 ° only when the
horizontal orientation
(Fig.5) is
0°.
