Mounting lever and angle bracket to TZIDC
• Attach the lever (1) to the positioner's feedback shaft (2) (can only be mounted in one
position due to the flat on the side of the feedback shaft).
• Check whether the lever travels within the operating range (between the arrows) by
observing the arrow marks (3).
• Hand-tighten the screw (4) at the lever.
• Hold the preassembled positioner with the angle bracket (5) still loose in such a way
against the actuator that the follower pin on the lever introduces into the follower
guide, in order to determine the bore holes of the positioner to be used for the angle
bracket.
• Fasten the angle bracket (5) with screws (6), and plain washers (7) to the correspond-
ing bore holes in the positioner case; if possible, tighten the screws evenly to ensure
linearity during operation. Align the angle bracket in the oblong hole to achieve a sym-
metrical operating range (between the arrow marks (3)).
