Readhead Mounting And Alignment - Renishaw QUANTiC RTLC40 Installation Manual

Readhead mounting and alignment

Mounting brackets
The bracket must have a flat mounting surface and should provide adjustment to enable
conformance to the installation tolerances, allow adjustment to the rideheight of the readhead,
and be sufficiently stiff to prevent deflection or vibration of the readhead during operation.
Readhead set-up
Ensure that the scale, readhead optical window and mounting face are clean and free
from obstructions.
NOTE: When cleaning the readhead and the scale apply the cleaning fluid sparingly, do not soak.
1. Mount the readhead to the bracket using 2 M2.5 screws.
2. To set the nominal rideheight, place the black spacer with the aperture under the optical
centre of the readhead to allow normal LED function during the set-up procedure.
3. Adjust the readhead to achieve a flashing green LED along the full axis of travel. The faster
the flash rate, the closer it is to optimum set-up.
The optional Advanced Diagnostic Tool ADTi-100 (A-6195-0100) and ADT View software can
be used to optimise signal strength in challenging installations. See
more information.
NOTE: When reinstalling the readhead, the factory defaults should be restored (see
factory defaults' on page 25).
