Installation With Mounting Spar - Renishaw FORTiS-N Installation Manual

14.4 Installation with mounting spar

Renishaw recommends the use of a mounting
spar where measuring lengths are greater than
620 mm. This requires encoders with short
end caps. Where measuring lengths are less
than 620 mm, if short end caps are specified,
the mounting spar should also be used. If in
doubt, please contact your local Renishaw
representative.
The spar should be installed prior to fitting the
encoder.
NOTE: Secure fastenings with Loctite 243.

Place the mounting spar on the mounting surface and firmly push

the surface mounting holes. Loosely secure the mounting spar to the
mounting surface with appropriate M6 screws.
NOTE: Secure fastenings with Loctite 243.

Position the encoder against the spar.
Inset: Ensure the clips on the mounting spar engage correctly with
the extrusion profile.
