NOTE: Ensure the guidance in
'Storage and handling' on page 5
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 covers
scale installation drawing' on page
3 Thoroughly clean and degrease the substrate using recommended
solvents (see 'Storage and handling' on page
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, 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' point (as shown). Ensure backing tape
is routed under the splitter screw.
7 Apply finger pressure to the scale at the 'START' point, using a clean
lint-free cloth, to ensure scale end adheres well to the substrate.
