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, the circuit is protected
by additional relay. Photocell is destined to work in gate automation system as external element.

3. Photocell mounting.
For proper funcionality photocell must be mounted 40-60 cm off the ground, receiver and
transmitter distance not less than 1 m. Photocell has angle of view adjustment in receiver and transmitter.
Coaxial mounting is unnecessary. Give consideration to electric boards maximum angle of rotation inside
transmitter and receiver enclosure. 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 green 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.
Do not mount mirrors or reflection
screens in photocell's working area, if
possible mount the receiver on the less
exposed to the sun side, do not mount the photocell
receiver in a location exposed to strong light source
of stray light, especially fluorescent light, it can
