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 maximise the signal strength
along the full axis of travel to achieve a Green set‑up LED on the readhead (> 70% signal). If a digital Ti / TD
interface is used, aim for a Blue LED on the interface.
NOTE:
The readhead should be installed and set-up with the AGC switched off (CAL LED off).
When re-installing, factory defaults should be restored
('Restoring factory defaults', page 15)

Alarm output will take the form of 3‑state or line driven E− signal depending on interface configuration.
Also, some configurations do not output overspeed alarm.
•
Momentary status only, while fault condition remains.
•
Alarm may result in axis position error, re-datum to continue.
