RKLC20-S scale application
(continued)
There are two versions of applicator for use with RKLC20-S scale: side mounted and top mounted. The side
mounted version is shown below, but the application method is the same for both versions of the applicator.
1.
Allow scale to acclimatise to installation environment prior to installation.
NOTE:
RKLC scale should be installed b10 °C and +35 °C to ensure scale mastering.
2. Mark out the start position for the scale on the axis substrate – ensure that there is room for the end
clamps
('RKLC20-S scale installation drawing', page 5) .
3. Thoroughly clean and degrease the substrate using recommended solvents ('Storage and handling',
page 2) . Allow substrate to dry before applying scale.
4. Mount the scale applicator to the readhead mounting bracket. Place the green spacer supplied with the
readhead between the applicator and substrate to set the nominal height.
NOTE:
Scale applicator can be mounted either way round to enable easiest orientation for scale installation.
5. Move axis to 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 scale into the applicator up to the start
position (as shown). Ensure backing paper is routed under the splitter screw.
7. Apply firm finger pressure via a clean, dry, lint‑free cloth to ensure scale end adheres well to the substrate.
8. Slowly and smoothly move the applicator through the entire axis of travel, ensuring the backing paper is
pulled manually from the scale and does not catch under the applicator.
9. During installation ensure scale is adhered to substrate using light finger pressure.
10. Remove applicator carefully. Apply firm finger pressure via a clean lint‑free cloth along the length of the
scale after application to ensure complete adhesion.
11. Clean the scale using Renishaw scale wipes or a clean, dry, lint-free cloth.
12. Fit end clamps
