RTLF tape scale: Application (any length)
There are three versions of applicator for use with RTLF scale
depending upon the design of the readhead mounting bracket:
Slim applicator (A-9402-0060) which is mounted in place of the
readhead bracket. It can be used in conjunction with the side
mounting bracket (A-9401-0103) or a customer designed bracket.
Side mount applicator (A-9402-0034) which is mounted in place
of the readhead bracket. It can be used in conjunction with the
‘L’ mounting bracket (A-9402-0037) or a customer designed bracket.
Top mount applicator (A-9402-0028) which is mounted in place
of the readhead. It can be used in conjunction with the
‘L’ mounting bracket (A-9402-0037) or a customer designed bracket.
Allow scale to acclimatize to installation environment prior to
1
installation.
2
Mark out the ‘START’- position for the scale on the axis substrate.
3
Thoroughly clean and degrease the substrate using a lint free cloth
and recommended solvents (see 'Storage and handling'). Allow
substrate to dry before applying scale.
Slim and side mount applicators:
4
Mount the applicator in place of the readhead bracket.
Top mount applicator:
Mount the applicator on a specically designed bracket in place
of the readhead.
Move axis to scale 'START' position, leaving enough room for the
5
scale to be inserted through the applicator, as shown below.
Check correct scale orientation.
6
When using the slim or side mount applicators begin to peel off
7
the backing paper from the end of the scale and insert the scale
into the applicator up to the ‘START’ point. Ensure the backing
paper feeds out of the back of the applicator around the splitter
screw as shown.
When using the top mount applicator cut the backing paper
approximately 30 mm from the end of the scale. Leaving the
end piece adhering to the scale begin to peel off the remaining
backing paper. Insert the scale into the applicator up to the
start position. Ensure the backing paper feeds out of the
back of the applicator round the splitter screw as shown.
Apply nger pressure via a clean lint free cloth to ensure scale
8
end adheres well to the substrate.
Slowly and smoothly move the applicator through the entire
9
length of travel, ensuring the backing paper is pulled manually
from the scale and does not catch under the applicator.
During installation ensure scale is adhered to substrate using
10
light nger pressure.
Remove applicator carefully and, if necessary, adhere the
11
remaining scale manually. NOTE: when using the top mount
applicator ensure the backing paper left at the start of the axis
is removed.
Apply a rm nger pressure via a clean lint-free cloth along the
12
length of the scale after application to ensure complete adhesion.
Slim and side mount applicators:
Fit readhead mounting bracket after removal of scale applicator.
Clean the scale using Renishaw scale wipes (A-9523-4040)
13
or a clean, dry, lint-free cloth.
Fit datum clamp and end covers and, if needed, deselect
14
reference marks that are not required as detailed on page 8.
For more information on designing your bracket and mounting the
chosen scale applicator contact your local Renishaw representative.
