3. Now use two hexagon socket screws to mount the
upper antenna segment removed in Point 1 on the
lower antenna segment.
Make sure that the two fan‐type lock washers are
inserted between the antenna segments (these
ensure that there is a defined contact resistance)!
Important
To make sure that they function perfectly, the fan‐type
lock washers (A5.3-FST DIN 6798 ZN/galvanized) must
be replaced after the bolted antenna connection has
been loosened three times.
4. Now tighten all the bolted antenna segment connec
tions with a tightening torque of 5 Nm.
5. Rotational speed measurement without a sensor for
the reference signal (zero index):
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 same
position as the center of the transmitter winding on
the rotor.
To make this alignment easier, the antenna segment
and the transmitter winding on flange B have the
same width. Please comply with the permissible align
ment tolerances stated in the specifications.
