1. Principle of operation.
Photocell includes transmitter and receiver (fig.1).The transmitter emit a coded Irfrared
(IR) signal , invisible to the naked eye. Obstacle appearance (e.g. car) on photocell working area
produces a detection signal on receiver output. Receiver has NC and NO type output contacts.
Photocell is destined to work in gate automation system as external element. Built-in signal
lamps in both, receiver and transmitter, supplied with 24V, fulfill signal function in gate system.

3. Photocell mounting.
For proper funcionality photocell must be mounted coaxial, 40-60 cm off the ground,
receiver and transmitter distance not less than 1 m . Because of photosensitive elements it is
recommended to mount receiver on less sun exposure side. Both receiver and transmitter must
be mounted vertically. Terminal blocks and humidity carrying openings should be in the
bottom part of enclosure. Proper receiver and
transmitter adjustment is
facilitated by
receiver's
diode RX. RX diode lights when
transmitter ray reaches receiver. Both
enclosures should be mounted by 2 (diagonal
mounting) or 4 screws available in set. To scale
down photocell sensitivity (minor receiver and
transmitter distance) it is recommended to
dismount transmitter's lens.
