opportunity for horizontal and vertical adjustments. Do
not fully tighten the bolts yet.
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 in
serted 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 N⋅m.
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 has the
same position as the center of the transmitter winding
on the rotor.
To make alignment easier, the outer edge of the stator
antenna segment and the outer edge of the stator
winding carrier should be on the same line (in align
ment). Conform to the permissible alignment toler
ances stated in the specifications.
