Fitting The End Covers; Fitting The Datum Clamp - Renishaw QUANTiC RTLC40-S Installation Manual

Fitting the end covers

The end cover kit is designed to be used with the RTLC40-S scale to provide protection for
exposed scale ends.
NOTE: The end covers are optional and can be fitted before or after installation of the readhead.
1. Remove the backing tape from the adhesive tape on the back of the end cover.
2. Align the marker on the edges of the end cover with the end of the scale and place the end
cover over the scale.
NOTE: There will be a gap between the end of the scale and the adhesive tape on the end cover.

Fitting the datum clamp

IMPORTANT: Allow 24 hours after scale application before fitting datum clamp.
The datum clamp fixes the RTLC40-S 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 customers' requirements.
1. Remove the backing paper from the datum clamp. Place the datum clamp with cut-out
against the scale at the chosen location.
2. Place a small amount of adhesive (Loctite 435) in the cut-out on the datum clamp, ensuring
none of the adhesive wicks onto the scale surface. Dispensing tips are available.
Ensure the adhesive wicks along
the entire length of cut-out.
