Structure and Functioning.
The operation of the system is based on recording the reflected luminous beam.
A photosensor run in a single housing with a light emitter is located at some angle in the horizontal plane on one of the cranes to the normal of the retroreflective element located on the other. Thus, the incident beam from the light emitter falls on the retroreflective element only in a certain range of distances between the cranes. The maximum and minimum distance between the cranes at which the light beam hits the retroreflector is determined by the angle of the sensor installation and its displacement relative to the center of the retroreflector. The foregoing is more clearly illustrated in the figure.
Fig. Simplified schematic diagram of the equipment layout.
Upon a reflected luminous beam registration, the discrete output of the photosensor is triggered. In this case, the relay connected to the digital output is switched off, and the light alarm is activated.
The following indicating devices are installed on the relay module:
power indicator (green);
protection indicator (red).
The power indicator lights up smoothly if the relay unit is properly connected to the 380V, 50Hz network.
The indicator of the protection operation lights up smoothly if the distance between the cranes falls within the operating range of the system.
The sensor operation description can be found in the documentation supplied with the sensor.
