INFRARED SYSTEM USER MANUAL Similar to the radio control, this infrared (IR) blocking system incorporates a safety code, meaning that it is highly reliable when several machines are operating at the same time as any possible interferences are avoided. The coverage area of the IR system depends on the height of the IR transmitter and how many are installed, as if the working range covered by one single IR transmitter is considered insufficient, more transmitters can be installed thereby increasing the working range. The number of transmitters will depend on the size of the surface area to be covered. Because of the optical nature of infrared rays, in order for the IR receiver to correctly acknowledge the IR transmitter signal, the transmitter should be located at a visible point and free of obstacles, otherwise the signal will not be received. The operation of this equipment is limited to covered areas, where there is no direct sunlight, as this significantly reduces the working range of the infrared system. The delimited area will depend on the application. 2. INSTALLATION OF THE INFRARED TRANSMITTER To connect the transmitter, first remove the front cover, by pressing and turning it anti-clockwise. Then unscrew the two fastening screws of the circuit to access the backside, where the input binding post is located. Input feed should be 48/115/230Vac 50Hz and will be connected to the binding posts of the CN3 connector. To select the correct voltage, close one of the jumpers J7, J8 or J9, as shown in figure 3. The default configuration is a voltage of 230Vac (J9). 1A FUSE 48Vac 115Vac 230Vac CURRENT FEED J7 J8 J9 FUS1 CN3 FASTENING SCREW RS485 PORT A B FASTENING SCREW Fig.3.
