SLIM II photocell

MOUNTING INSTRUCTION

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.

2. Technical data.

4 Guaranteed range 1-15 m
4 Angle of view adjustment horizontally 200° in receiver and transmitter
4 Power suplly of transmitter and receiver 12-24V AC/DC

(synchronization option requires AC supply)

4 Current consumption of transmitter max. 25 mA
4 Current consumption of receiver max. 25 mA
4 Working temperature (min. / max.) -20°C / +55°C
4 Outside dimensions (WxDxH) 35 x 30 x 110 mm
4 Mounting surface mounted splash proof case - Ip54
4 Output contacts NO and NC

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
inter f e r e t h e b a r rier. B e w are of o p tical

4. Photocell connection

Photocell cooporates 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
and description below.

Without synchronization function

4Make sure the ZW jumper on the transmitter and

receiver are mounted.

4Connect the power supply 12-24V AC/DC to

photocell transmitter and receiver. POWER LEDs
on the transmitter and the receiver, and RX LED on
the receiver should light up.

4If you use the AC power supply to power the

transmitter and receiver use the same phase (with
one power supply)

4Connect the output signal of photocell (usually NC

and C) to proper inputs on the control unit. Pay
particular attention to the type of control (NC or NO)
required in the control panel. The standard solution
for gate automation is to work with optical sensors in
the NC.

With the use of synchronization function

Using synchronization function, you can
install two pairs of photocells with the
overlapping area of 󰾬󰾬the optical range.

To use the synchronization function, you

must cut the ZW jumper in photocell transmitter and
receiver, and supply them with alternating voltage
(12-24V AC).
Connect the same wire to the terminal marked "1" on
the transmitter and the receiver of the first pair of
photocells. If swap wires only on the transmitter side
or only on the receiver side, will result in no action of
photocells. The second pair of photocells must be
powered by the same phase as the first, but wires in
the supply line of transmitter and receiver must be
swap. (the power wire connected to the terminal
marked "1" in the first pair of photocells, must be
swap with the next wire in the second pair of
photocells).
