Scale application
There are two versions of applicator for use with RGSZ20 scale:
side mounted (A-9653-0182) and top mounted (A-9653-0273).
1
Allow scale to acclimatize to installation environment prior to installation.
2
Mark out 'START' and 'FINISH' points for the scale on the axis substrate - ensure that there is room
for the end clamps (see 'RGSZ20-S installation drawing').
3
Thoroughly clean and degrease the substrate using recommended solvents (see 'Storage and handling').
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 'START' of travel.
6
Begin to remove the backing paper from
the scale and insert into the applicator
up to the 'START' point (as shown).

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 lint-free cloth to ensure scale end adheres well to substrate.

8
Slowly and smoothly move the applicator through the entire axis of travel, ensuring that the
backing paper is pulled manually from the scale and does not catch under the applicator.
9
Remove applicator carefully and, if necessary, adhere remaining scale manually.
Apply firm finger pressure via a clean lint-free cloth along the length of the scale after
application to ensure complete adhesion.
10
Clean the scale using Renishaw scale wipes (A-9523-4040) or a clean, dry, lint-free cloth.
11
Fit end clamps (see 'End clamps' section).
12
Allow 24 hours for complete adhesion of scale before fitting reference mark selector magnet
and limit magnets.

End clamps
A-9523-4015 is an end clamp kit designed to be used with Renishaw RGSZ scale.
NOTE: End clamps can be mounted before or after readhead installation.
1
Remove the lacquer coating from the last
15 mm of each end of the scale with a knife
and clean with one of the recommended
solvents (see 'Storage and handling').
'START' point
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.
Ensure that excess glue is wiped away from scale as
it may affect the readhead signal level.
2
Thoroughly mix up a sachet of glue
(A-9531-0342) and apply a small amount
to the underside of the end clamp.
4
Immediately position end clamp
over the end of the scale.
Allow 24 hours at 20 °C
for full cure.
