5.2.1 Requirements
The following instructions are not exhaustive as the assembly situation may be different for
each application.
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 fixing the
clamping ring in position, see Figure 2.
Further measures may be required to prevent axial slipping of the measuring system.
There may be no axial load on the clamping mechanism of the measuring system.
The screw of the clamping ring must be tightened with 3 Nm using a torque wrench.
The screw of the clamping ring must be secured such that it cannot be loosened accidentally.
Radial slipping of the measuring system on the drive shaft must be prevented by a form-
locking connection, using a parallel key / groove combination; the measuring system must be
fixed in position on the drive end using a dowel pin, see Figure 2.
The dowel pin must extend at least 4 mm into the groove insert, max.5.5 nm. The distance
from the measuring system flange
Y
to the customer-provided device plane
X
must be > 1.5
mm, see Figure 2.
