The blinkers work on the following principle: a special counterweight is placed on the lever of the gates. When the mass of accumulated dust and particles on the shutter becomes greater than the mass of the counterweight, the blinker is cleared of contaminants.
Once the shutter is free of dust, the counterweight will return the shutter to its original position.
