1 Rotary limit switch FOX Rotary limit switch used to control and measure the movement of industrial machines by measuring the rotation angle and/or counting the number of revolutions of a shaft. Fox is used on wind turbines to control the position of the nacelle or the pitch angle of the blades. FeatuRes It consists of a gear motor that transfers movement to the cams and the other movement detection devices 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: up to 10 million operations. IP protection degree: Fox is classiied IP66, IP67 and IP69K. NEMA protection degree: Fox is classiied Type X*. Extreme temperature resistance: -0 C to +80 C. It features transmission and gear driving shafts made of stainless steel AISI 30F or AISI 303. worm gear transmission shaft rotating on ball bearings, self-lubricating technopolymer gears and driving bushes, technopolymer base and cover. All materials and components used are wear resistant and guarantee protection of the unit against water and dust. OptiOns Revolution ratios from 1:3 to 1:2870. achieved by combining different secondary output stages. Snap action switches with 1NO+1NC change-over contacts or slow action switches with 1NC contact. It can be equipped with a cam set (with up to 5 switches) and potentiometers, encoders. Yankee absolute encoders. 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. Plates with universal adapter to replace existing systems. CeRtiFiCatiOns CE marking, culus* marking and EAC certiication. Fox is available, upon request, with the SIL1 certiication (Safety Integrity Level 1), according to Standard IEC Complies with accident prevention regulation BGV C 1 (only for Germany) HALT TEST (Highly Accelerated Life Test) passed. simulating conditions largely exceeding standard operating conditions.

15 use and maintenance instructions Fox rotary limit switch is an electromechanical device for low voltage control circuits (EN EN ) to be used as electrical equipment on machines (EN ) in compliance with the fundamental requirements of the Low Voltage Directive 2006/95/CE and of the Machine Directive 2006/2/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 limit switch is supplied with a bag of accessories including: 2 self-locking nuts (7), 2 metric screws (1), 1 no-drop wire (2), 1 self-tapping screw (3), 1 cable clamp (). Furthermore, accessories may include, in addition to the above-mentioned parts and instead of the cable clamp (), 1 double cable clamp holder (1), 2 cable clamps M20 (15) or 1 cable clamp M20 (15) and 1 cable clamp M16 (16). 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 - Place the self-locking nuts (7) in their seats in the enclosure (6). - Insert one end of the no-drop wire (2) into the self-tapping screw (3) and tighten the screw into its hole on the enclosure (6). - Connect the limit switch shaft (8) and the reduction gear shaft avoiding any misalignment between the two shafts. - Fix the limit switch tight in order to avoid vibrations of the equipment during operation; for ixing operations use only the feet (9) with metric screws M or M5 and their washers. - In case a single multicore cable is employed, screw the cable clamp () to the enclosure (6); when two multicore cables are employed, use the cable clamp holder (1), then screw cable clamps (15, 16) to the cable clamp holder. - Insert the cable into the limit switch through the cable clamp (, 15, 16). - Strip the multipole cable to a length suitable for stripping the single poles; we suggest the use of pin terminals. - Clamp the wire into the cable clamp (, 15, 16). - Connect the switches according to the contact scheme printed on the switches or to the wiring scheme on the back of the instructions (tighten the wires into the terminals with a torque equal to 0.5 Nm; (UL (c)ul: use 60 C or 75 C copper (CU) conductors and stiff or flexible wire 1-16 AWG); insertability of wires into the terminals 2x0.5mm 2 2x1.5 mm 2 1x2.5 mm 2 ). - 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 adjusting screw () (the numbers on the screws refer to the cams counting from bottom to top of the set), then tighten the central screw (). - Insert the free end of the no-drop wire (2) into one of the metric screws (1), then tighten the metric screws (1) to close the limit switch; check the proper positioning of the rubber in the cover (5) and tighten the screws (1) with a torque of 80/100 cnm. steps for routine maintenance - Check the proper tightening of the screws (1) of the cover (5). - Check the proper tightening of the switch terminal screws. - Check the proper tightening of the central screw () holding the cams (). - Check the wiring conditions (in particular where wires clamp into the terminals). - If there is an anti-moisture plug, check its conditions. - Check the conditions of the rubber it into the cover (5) and check the tightening of the cable clamp (, 15, 16) around the cable. - Check that the limit switch enclosure (5, 6) is not broken. - Check the alignment between the limit switch shaft (8) and the reduction gear shaft. - Check that the limit switch is properly ixed. Any change to parts of the limit switch will invalidate the rating plate and identiication data of the device. and render the warranty null and void. In case of replacement of any part. use original spare parts only. TER declines all responsibility for damages caused by the improper use or installation of the equipment.
