Preparing the Actuator
Prepare the rotary adapter:
• For attachment to a counter-clockwise or left turning actuator, secure the stud screw 4 in the threaded hole “L” of the
rotary adaptor; hole “R” remains open
• For attachment to a clockwise or right turning actuator secure the stud screw 4 in the threaded hole “R” of the rotary
adaptor; hole “L” remains open Stud screw should always be tightened into the flat on the on the feedback shaft 9
Place the rotary adaptor 3 with two washers 5 on the feedback shaft 9 of the positioner against the stop
NOTE: N When the product temperature rises, the drive shaft 1 becomes longer Therefore, mount the rotary adaptor 3 with
approximately 1 mm (0 04 in ) of clearance between the drive shaft 1 and the rotary adaptor 3 Add washers 5 on the
feedback shaft stub 9 before attaching the rotary adaptor Two washers should result in a clearance of 1 mm
Screw and tighten the bolt in the coupling against the flat part of the feedback shaft (do not screw against thread!)
Turn the feedback shaft so that the arrow of the coupling points to the arrow of the SRD housing Beginning and end
positions of the actuator drive shaft 1 and feedback shaft 9 are marked by arrows for the respective direction of rotation
The feedback shaft is now in the normal position corresponding to the failsafe position of the actuator
