1. Prior to installation, clean the plane faces of the transducer flange and the
counter flange.
For safe torque transfer, the faces must be clean and free from grease. Use
a piece of cloth or paper soaked in solvent. When cleaning, make sure that
you do not damage the transmitter winding or the rotational speed measur­
ing system.
2. For the bolted rotor connection ( see Fig. 5.1 ), use six or eight DIN EN ISO
4762 hexagon socket screws of the property class stated in Tab. 5.1, in a
suitable length (dependent on the connection geometry,
see Tab. 5.1 on
page 22 ).
We recommend DIN EN ISO 4762 socket head cap screws, blackened,
smooth‐headed, permitted size and shape variance in accordance with DIN
ISO 4759, Part 1, product class A.
3. Fasten all screws with the specified torque ( Tab. 5.1 on page 22 ).
4. There are six or eight tapped holes on the rotor for continuing the shaft train
mounting. Again use screws of property class 10.9 or 12.9 and tighten them
with the prescribed torque, as specified in
Tab. 5.1 .
