MOUNTING INSTRUCTION

1. Principleofoperation.

Photocell includestransmitter and receiver(fig.1).Thetransmitter emit acoded Irfrared
(IR) signal ,invisible to thenakedeye.Obstacle appearance (e.g. car)on photocell workingarea
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

3. Photocellmounting.

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 mountreceiver onless sun exposure side.Both receiverand 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

4. Photocellconnection

Photocell cooperates with most of gate controllers available on market. It is
recommended to do electrical installation and photocell mounting by qualified person.
Connect photocell according to fig. 3 scheme. First find 24V AC/DC clips (polarity is not

important!) intended to power supply, in gate controller. Connect power supply to receiver
and transmitter.When power is on red LED’s (POWER) in receiver and transmitter light. Next
connect gate controllerinput to photocell'sreceiver output (RX pins: 1,2or 2,3). Payattention
