TONiC RKLC20-S linear installation guide

1 Allow scale to acclimatize to 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 end clamps.
(see ‘RKLC20-S scale installation drawing’)
3 Thoroughly clean and degrease the substrate using recommended solvents
. Allow substrate to dry before applying scale.
4 Mount the appropriate 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: 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.
6 Begin to remove the backing paper from the scale and insert scale into the applicator
up to the ‘START’ point (as shown).
Ensure backing paper is routed under the splitter screw.
Scale application
There are two versions of applicator for use with RKLC20-S scale: side mounted
(A-6547-1912) and top mounted (A-6547-1915). The side mounted version is shown below,
but the application method is the same for both versions of the applicator.

During installation ensure scale is adhered to substrate using light finger pressure.
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.
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 (A-9523-4040) or a clean, dry, lint-free cloth.
12 Fit end clamps see 'End clamps' below.
7 Ensure that the end of the scale is in line with the ‘START’ position on the axis and
apply finger pressure via a clean line‑free cloth to ensure scale end adheres well to
the substrate.

End clamps
A-9523-4015 is an end clamp kit designed to be used with Renishaw RKLC20-S scale. Alternatively, narrow
6 mm wide end clamps (A-9523-4027) are also available.
NOTE: End clamps can be mounted before or after readhead installation.
Ensure that excess glue is wiped away from
scale as it may affect the readhead signal level.
3 The end clamp features two small regions of contact
adhesive. These will temporarily hold the end clamp
in position while the glue cures. Remove the backing
tape from either side.
1 Clean ends of scale and the area where end clamps
are to be fitted using Renishaw scale wipes
(A-9523-4040) or one of the recommended solvents
4 Immediately position end clamp over the end of
the scale and push down to ensure complete
adhesion. Allow 24 hours at 20
°C
for full cure.
2 Thoroughly mix up a sachet of glue (A-9531-0342)
and apply a small amount to the underside of the
end clamp.
