5.2.1 Requirements

As the installation situation is application-dependent, the following notes are not exhaustive.
➢ The measuring system must be installed on a grease-free shaft.
➢ Axial slipping of the measuring system on the drive shaft must be prevented by the fixing of the
clamping ring, see Figure 3.
➢ Further measures may be required to prevent axial slipping of the measuring system.
➢ The clamping of the measuring system must not be axially loaded.
➢ The screw of the clamping ring must be tightened with 3 Nm using a torque wrench.
➢ The screw must be secured against unintentional loosening.
➢ Radial slipping of the measuring system on the drive shaft must be prevented by means of form
closure, using a parallel key / groove combination; the measuring system must be fixed on the
drive shaft using a dowel pin, see Figure 2. The dowel pin must extend at least 4 mm into the
groove insertion.
