The contactless détection of perforations allows the number of bags/batches to be determined and indicates when the material rolls need to be changed. Mode of opération Sparks are generated at the point of the perforation of the film by means of a high-voltage électrode (counting électrode) and a suitable earthed/grounded counter-electrode. Thèse sparks are interpreted and counted by the logic circuit integrated in the PZ 3 perforation counter and indicated visually on the display through a light-emitting diode. The counting puises transmitted by an opto-coupler can be interpreted by an external counter and may be used for activating other machine functions (such as the control of reversing winding machines and cutting machines). Direotions for installation The counting électrode must be mounted above the material web at a distance of approx. 10 to 20 mm and centered over the perforations to ensure the perfect functioning of the PZ 3. An earthed/grounded counter-electrode below the material web (e.g. earthed métal drum) must be in physical contact with the foil opposite the counting électrode. Photo 1 Speoial features and advantages • The PZ 3 perforation counter offers the possibility to capture up to 900 counting puises per minute. This corresponds to a counting rate of 15 counting puises per second (15 Hz). • The duration of the counting impulses is adjustable from 5 to 1000 ms. This helps to suppress subséquent spark-overs that may be triggered by "holes" in the film and should not be counted. • The high voltage applied to the counting électrode is infinitely adjustable from 2.4 up to 17 kVDC. • The external release of the output voltage can be activated through a voltage-free contact, so that high voltage is applied to the counting électrode, for instance when the material web is moving.
