ensuring the scale is fed under the projections
as shown.
Scale can be installed manually by either
pulling or pushing it through the
FASTRACK carrier.
Alternatively use the optional
scale installation tool
(A-9589-0420) as shown, for
easy installation.
7 Optional: fix self‑adhesive end covers
ensuring a gap of at least 1 mm between
the end of the scale and the end cover.
Ensure a gap > 1 mm

IMPORTANT: If manually installing
the scale using fingers, suitable
gloves should be worn to protect
against injury from sharp edges.
Scale datum
The datum clamp fixes the RTLC20 scale rigidly to the substrate at the location chosen.
CAUTION: The metrology of the system may be compromised if the datum clamp is not used.
The datum clamp does not need to be fitted adjacent to a reference mark. It can be positioned anywhere
along the axis depending upon the customer's requirements.

Adhesive clamp
Using dispensing tip P-TL50-0209 apply Loctite 435
between the scale and the FASTRACK carrier so it
wicks underneath adjacent to user selected datum
location as shown.
NOTE: Drawing shows the scale datum adjacent to
the chosen reference mark.
NOTE: Only apply Loctite 435 in
these gaps to ensure best bond.
Loctite 435 will wick under the
scale to lock it to the substrate.
