Scale Application; End Covers - Renishaw VIONiC RTLC20-S Installation Manual

Scale application

The scale applicator (A-9589-0115) is designed for use with RTLC20-S scale.
1 Allow the scale to acclimatise to the installation environment prior to
installation.
2
Mark out the 'START' and 'FINISH' points for the scale on the axis
substrate – ensure that there is room for the optional end covers if required
(see 'RTLC20-S scale installation drawing' on page
3 Thoroughly clean and degrease the substrate using recommended solvents
(see 'Storage and handling' on page 2). Allow the substrate to dry
before applying scale.
4
Mount the scale applicator to the readhead mounting bracket using M2.5
screws. Place the shim supplied with the readhead between the applicator
and substrate to set the nominal height.
NOTE: The scale applicator can be mounted either way round to enable
easiest orientation for scale installation.

Move the axis to the scale 'START' position, leaving enough room for the
scale to be inserted through the applicator, as shown below.
6 Begin to remove the backing paper from the scale and insert the scale
into the applicator up to the 'START' point (as shown). Ensure the backing
paper is routed under the splitter screw.
7 Apply finger pressure to the scale at the 'START' point, using a clean
lint-free cloth, to ensure scale end adheres well to the substrate.
