Readhead mounting and alignment
Methods
There is a range of tools available to assist with readhead installation depending upon the system design; these are
detailed below. For more details on designing the mounting bracket and selecting the appropriate mounting tools,
contact your local Renishaw representative.
Ensure that the scale, readhead optical window and mounting face are clean and free from obstruction.
CAUTION: Do not saturate the readhead window with cleaning solvent as this may cause contamination on the inside of
the readhead window which cannot be cleaned.
NOTE: For FPC readheads, the FPC cable must be fitted prior to mounting the readhead. See
IMPORTANT: Whichever method is used to mount the readhead, care should be taken to ensure the scale surface is not
damaged during this operation, particularly when metal-to-metal contact is necessary.
