3 TECHNICA DATASHEET Description These rope operated safety switches can be installed on machines or conveyor belts and are used to activate the emergency stop of the machine on intervention with the rope, at any point. They allow for cost savings on machines of medium-large size, where normally numerous emergency stop push buttons can be replaced by one single rope switch. Provided with a self-control function, when fitted properly they constantly check for correct operation, signalling with the opening of the contacts with a manual intervention (emergency stop activation) of an eventual pull, loosening or breaking of the rope. After activation the contacts remain open, until they are reset. Orientable heads aser engraving The markings of all devices are ASER printed on to the unit. As the markings are directly printed they are less likely to be rubbed off and do not fall off as found with some attached labels, making them suitable for extreme environments. Removing the four fastening screws makes it is possible to rotate the head in 90 steps. Protection degree IP6 These devices are designed to be used in the toughest environmental conditions and they pass the IP6 immersion test acc. to IEC 529. Indicator for the state of the reset Armed Reset Released Reset Reduced actuating force These switches can be supplied with a spring requiring less tension for movement hence reducing the effort needed to actuate the switch, while, maintaining the correct actuation of the electrical contacts. If the rope tensioning indicator is in the correct area, within the green band, the unit can be reset by pulling the blue button to close the safety contacts. The state of the switch can be quickly checked by observing the tension indicator s position with respect to the green band, and the blue button in the Released Reset/Armed Reset state. Adjustment point indicator of the rope All switches are provided with a green band, this green band area is for setting the correct tensioning of the rope. The installer has to tension the rope until the black indicator is set to the middle of this green band. Extended temperature range This switch range is also available in a special version with an ambient operating temperature range of - C to +80 C for low temperature environments such as cold stores and sterilisers. When set, a pull or loosing of the rope allows the black indictor to travel to the outside of the correct tension area (green band), at this point the safety contacts are opened and the reset device is triggered. Adjustment of the operating point Tension indicator Area of correct rope tightening Tighten the rope connected to the switch, until the end of the indicator (1) reaches about the middle of the green ring (2). Pull the knob (3) in order to close the safety contacts inside the switch. A green band (4) will be exposed to indicate the Armed reset condition. p3
