WIRINGAND INSTALLATION
On the receiving module 16 red LEDs show the status of each beam. Plug connectors with 3.5 mm pitch are used. The 2 twisted wires enable the connection of each head to the controller. The wires must be between 0.5 m and 5 m long. Thanks to the multiplexing of the heads, there is no interference between two heads.
The status information of the beams are transmitted to the controller via a RS485 communication. It is possible to connect other terminals (maximum 32) on this bus.
The 2 modules composing the system are housed in aluminum profiles that can be fixed with screws or with
A green LED on the emitting module indicates if the module is on. If the link between the 2 modules is not correct, the LED will remain off and the MULTIBEAM will not work properly.
A potentiometer on the emitting module allows to adjust them emission power in order to reduce the influence of one module to an other module in close proximity (turn clockwise = increase emission power).
The receiver has a green cable and the emitter a yellow cable. Wiring Diagram:
