RTLF / RKLF tape scale
(continued)
RKLF end clamps
The end clamp kit is designed to be used with Renishaw RKLF scale to ensure the scale is mastered to the
substrate. Alternative narrow 6 mm wide end clamps (A-9523-4111) are also available.
NOTE: End clamps can be mounted before or after readhead installation.
1.
Clean ends of scale and the area
where end clamps are to be fitted
using Renishaw scale wipes or
one of the recommended solvents
('Storage and handling', page
3).
2.
Thoroughly mix up a sachet of RGG-2 two
part epoxy adhesive and apply a small
amount to the underside of the end clamp.
*
To ensure scale end movement of typically < 1 µm, stabilise the system at least 5 °C higher than the maximum customer
application temperature for a minimum of 8 hours. For example: Customer application = 23 °C axis temperature.
Stabilise the system at 28 °C for a minimum of 8 hours.

3.
The end clamp features two small regions
of contact adhesive. These will temporarily
hold the end clamp in position while the
epoxy cures. Remove the backing tape from
either side.
CAUTION: Ensure that excess epoxy
is wiped away from scale as it may affect
the readhead signal level.
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 * .
RTLF / RKLF reference mark deselection
RTLF and RKLF scale > 100 mm in length has reference marks every 50 mm. Stickers can be used to
deselect all unused reference marks. The stickers are aligned on the backing paper with a 50 mm spacing
so two can be selected at once for deselecting two reference marks.
1.
Ensure the scale is free from dirt and grease by cleaning with a Renishaw scale wipe or one of the
recommended solvents
('Storage and handling', page
2.
Place the transparent applicator film over the reference mark deselector stickers and rub firmly until
the sticker adheres to the applicator film. Two stickers can be selected at once.
3.
Remove the applicator film, complete with the stickers, from the backing paper.
4.
Align the stickers on the scale over the reference marks that are not required, as shown in the
diagram, then rub firmly on the applicator film until the stickers adhere to the scale.
Care should be taken to ensure the stickers fully cover the reference mark and do not obscure any of
the incremental track.
