Before installation of the position indicator, a bore hole for the torque limiting contact point is to be drilled, as shown in the in the adjacent drawing.
With the Mounting Adaptors EN 952.1 the hollow shaft (with bore 14 H7) of the position indicator can be adapted to fit the spindle.
If a reduction in the diameter of the hollow shaft is to be made at the same time as mounting a control knob, Control Knobs GN 957 are available which combine both functions in a single component (no adaptor bushings required).
The position indicator is mounted with the torque limiting contact point inserted in the bore hole, to stabilize the housing in place. The hollow shaft is mounted to the spindle and secured with the set screw.
With Clamping Plates GN 9053.6 spindles can be clamped and secured after adjusting.
