4. Now tighten all antenna-segment bolted connections with a tightening torque of 5 Nm.
5. Then align the antenna to the rotor in such a way that the antenna encloses the rotor
more or less coaxially and the antenna wire in the axial direction shows the position and
the center of the transmitter winding on the rotor.
Please comply with the permissible alignment tolerances stated in the specifications.

oscillation
Depending on the operating conditions,
the stator may be excited to vibrate. This effect is
dependent on:
The rotational speed
The antenna diameter (depends on the measuring range)
The design of the machine base
