Rotary limit switch BASE Rotary limit switch used to control and measure the movement of industrial machines. Its compact size make it suitable for use in narrow spaces. FEAtuRES It consists of a gear motor that transfers movement through a primary input reduction stage (worm gear and helical toothed gear) and one or more secondary output stages (pairs of straight toothed gears). Accurate adjustment of cams by means of screws. Positive opening NC contacts for safety functions. Mechanical life of switches: million operations. IP protection degree: Base is classiied IP, IP6 or IP66, IP6 and IP6K. NEMA protection degree: Base IP66, IP6 and IP6K is classiied Type ; Base IP is classiied Type. Extreme temperature resistance: -0 C to +80 C. It features stainless steel transmission and gear driving shafts, self-lubricating technopolymer gears and driving bushes, technopolymer base and cover. Sintered bronze bushes are moulded into the base of the limit switch to optimize shaft rotation and prevent rubbing with plastic material. All materials and components used are wear resistant and guarantee protection of the unit against water and dust. OptiOnS Revolution ratios from : to :00, achieved by combining different secondary output stages. Snap action switches with NO+NC change-over contacts. It can be equipped with a cam set with maximum 6 switches. Dedicated cable clamps or connectors. Available with anti-moisture plug itted to the base by means of a lock nut, to improve transpiration for the limit switch whilst maintaining protection against water. Available with flanges, pinions and couplings. Available with direct control switches to enable direct action on the motor. CERtiFiCAtiOnS CE marking, curus* marking and EAC certiication. Complies with accident prevention regulation BGV C (only for Germany). The data and the products illustrated in this brochure may be modiied without notice. Under no circumstances can their description have a contractual value. * Not available on all versions.

use AnD maintenance instructions Base rotary limit switch is an electromechanical device for low voltage control circuits (EN 60-, EN 60--) to be used as electrical equipment on machines (EN 600-) in compliance with the fundamental requirements of the Low Voltage Directive 006//CE and of the Machine Directive 006//CE. The limit switch is designed for use in industrial environments under even severe climatic conditions (operational temperature from 0 C to +80 C, suitable for use in tropical environment). The equipment is not suitable for use in environments with potentially explosive atmosphere, corrosive agents or a high percentage of sodium chloride (saline fog). Oils, acids or solvents may damage the equipment; avoid using them for cleaning. Do not connect more than one phase to each switch. Do not oil or grease the control elements or the switches. The installation of the limit switch shall be carried out by expert and trained personnel. Wiring shall be properly done according to the current instructions. Prior to the installation and the maintenance of the limit switch, the main power of the machinery shall be turned off. Steps for the proper installation of the limit switch - Loosen the ixing screw () and remove the cover (.) - Connect the limit switch shaft () to the reduction gear shaft avoiding any misalignment between the two shafts. - Fix the limit switch irmly in place to prevent abnormal vibrations of the equipment during operation; use only the ixing holes on the base () to ix the equipment. - Tighten the cable clamp () into appropriate place. - Insert the cable into the limit switch through the cable clamp (). - Strip the cable to a length suitable for wiring the switches. - Tape the stripped part of the cable. - Clamp the wire into the cable clamp (). - Connect the switches according to the contact scheme printed on the switches or to the wiring scheme on the back of the instructions (use 6. mm Faston taps). - Adjust the operating point of the cams; for proper adjustment, loosen the central screw () of the cam set, adjust the operating point of each single cam by turning its screw (8) (the numbers on the screws refer to the cams counting from bottom to top), then tighten the central screw (). - Insert the free end of the no-drop wire (), if used, into one of the screws (), then close the limit switch using the screws (); check the proper positioning of the rubber (6) in the cover (0) and tighten the screws () with a torque of 80/00 cnm. periodic maintenance steps - Check the proper tightening of the screws () and cover (). - Check the proper tightening of the central screw () holding the cams. - Check the wiring conditions (in particular where wires clamp into the switch). - Check the conditions of the rubber (6) it between the cover () and the base () and check the tightening of the cable clamp () around the cable. - Check that the limit switch enclosure (, ) is not broken. - Check the alignment between the limit switch shaft () and the reduction gear shaft. - Check that the limit switch is properly ixed. - If there is an anti-moisture plug, check its conditions. In case any component of the limit switch is modiied, the validity of the markings and the guarantee on the equipment are annulled. Should any component need replacement, use original spare parts only. TER declines all responsibility for damages caused by the improper use or installation of the equipment.
