MI EVE0103 A-(en) <strong>SRI983</strong> 9 2.3.2 Attachment to rotary actuators For attachment of the positioner to rotary actuators or rotary armatures an attachment kit is required. The linear cam enables sensing of rotation angles up to 120°, wheras the equal percentage and the inverse equal percentage cams sense rotation angles up to 90° (linear characteristic between 70° and 90°). Attachment a) Remove the transparent cover plate from the housing 26 of the attachment kit. b) Mount the housing of the attachment kit on rotary actuator or armature; use mounting hardware supplied by the actuator manufacturer if necessary. Fig.14: Rotary actuator with attachment kit c) Move actuator into the desired starting position (rotation angle = 0°). d) Mount cam 24 in accordance with the direction of rotation of the actuator (see Fig. 15). The linear cam is fastened to the actuator drive shaft in such a manner that the dimension x or y (Fig. 16) amounts 2 mm, whereas in case of equal percentage cam the dimension x is approx. 17.5 mm, and the dimension y is approx. 21.5 mm. In case of inverse equal percentage cam the dimension x is approx. 18 mm, and the dimension y is approx. 23 mm. When employing equal percentage and the inverse equal percentage cams, the range spring 420 493 013 (included in spring set FESG-FN) must be installed in the positioner.
