Readhead Mounting And Alignment - Renishaw QUANTiC RKLC40-S 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 readhead and scale apply cleaning fluid sparingly, do not soak.
To set nominal rideheight, place the green spacer with the aperture under the optical centre of the readhead
to allow normal LED function during set-up procedure. 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
