INSTALLATION:
The photocells are designed to detect obstacles in auto-
matic door and gate installations, preventing collision with the door
/gate. They are made up of an infrared transmitter module (TX) and
receiver module (RX). If a person or object interrupts the beam of light
emitted by transmitter (TX) (or the beam does not reach the receiver
due tofailure or loss of setting), the receiver (RX) enables the corre-
sponding relay and informs the installation control unit.
Power supply: 12V AC/DC or 24V AC/DC.
Consumption (at 24VDC): TX: 20mA, RX: 25mA
Wavelength: 940nm
Rotate angle: 180
Infrared beam frequency: 1kHz
Response time: 110mS
Operating temperature: -20C
° / +60C °
IP protection: 44
Relay contacts capacity: 1A at 24VDC
Infrared beam range: 30m maximum (9m in adverse conditions)
Distance:10-30m
(1) Install the receiver (RX) keep away from direct sunlight
(infrared radiation).
(2) Choose a location for the transmitter and receiver equipment.
The two modules should be as aligned as possible.
(3) The installation height of photocells will depend on the installation
(in general, we recommend installation at a height of less than
300mm from the ground and at a distance of less than 200mm
from the leaf of the gate).
(4) Connect the electrical power supply. When the receiver correctly
receives the beam sent by transmitter, the NC contact remains
closed and LED light off. When the beam is interrupted, the NC
contact opens and LED light on. url:http://www.juhuitech.net |
