8 Scale application The scale applicator A is designed specifically for use with EVOLUTE readheads and RTLA50 S scale. 1 Allow scale to acclimatize to installation environment prior to installation. End covers The end cover kit A is designed to be used with RTLA50-S scale to provide protection for exposed scale ends. NOTE: End covers are optional and can be fitted before or after readhead installation. 2 Mark out the START and FINISH points for the scale on the axis substrate ensure that there is room for the optional end covers if required (see RTLA50-S (with adhesive datum clamp) installation drawing ). 1 Remove the backing tape from the adhesive tape on the back of the end cover. 3 4 Thoroughly clean and degrease the substrate using recommended solvents (see Storage and handling ). Allow substrate to dry before applying scale. Mount the appropriate scale applicator to the readhead mounting bracket using M3 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. 2 Align markers on the edges of the end cover with the end of the scale and place 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 Move axis to START of travel. 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. START point 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. Slowly and smoothly move the applicator through the entire axis of travel, ensuring the backing paper is pulled manually from the scale and does not catch under the applicator. Direction of scale application RTLA50-S Datum clamp The datum clamp (A ) fixes the RTLA50-S scale rigidly to the substrate at the location chosen. The metrology of the system may be compromised if the datum clamp is not used. It can be positioned anywhere along the axis depending upon the customer s requirements. 1 Place the datum clamp with cut-out against the scale at the chosen location. *gap Splitter screw Backing tape START 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 P-TL are available Remove applicator and, if necessary, adhere the remaining scale manually. Apply firm finger pressure via a clean lint-free cloth along the length of the scale after application to ensure complete adhesion. Clean scale using Renishaw scale cleaning wipes (A ) or a clean, dry, lint-free cloth. Fit end covers. Allow 24 hours for complete adhesion of scale before fitting datum clamps. Ensure the adhesive wicks along the entire length of cut-out. EVOLUTE RTLA50-S installation guide 6

Readhead mounting/installation Electrical connections Mounting brackets The bracket must have a flat mounting surface, enable conformance to the installation tolerances, allow adjustment of the

Readhead set-up Ensure that the scale, readhead optical window and mounting face are clean and free from obstructions. To set nominal rideheight for RTLA50-S installations, use the blue 0.

9 Readhead mounting/installation Electrical connections Mounting brackets The bracket must have a flat mounting surface, enable conformance to the installation tolerances, allow adjustment of the rideheight of the readhead, and be sufficiently stiff to prevent deflection of the readhead during operation. Readhead set-up Ensure that the scale, readhead optical window and mounting face are clean and free from obstructions. To set nominal rideheight for RTLA50-S installations, use the blue 0.8 mm readhead spacer to set rideheight. Adjust the readhead to maximize the signal strength along the full axis of travel to achieve a Green LED.
