Original instructions
14 Installation procedure – readhead
Three different methods may be used to install the readhead, making installation easier for a wide range
of machine types and mounting surfaces. These are outlined in the following sections.
Please note, installation of the extrusion follows the procedure outlined in section 13 on page 15 and is
independent of the readhead installation method being used.
14.1 Measuring length
The start of the measuring length (ML) is indicated by the triangular marking on the extrusion;
a corresponding arrow on the readhead should be aligned to this arrow to ensure the readhead is within
the encoder measuring length.
WARNING: Failure to ensure the readhead is within the measuring length of the encoder could lead to a
collision and damage.

Dimensions and tolerances in mm
Position Status Description
1 Closed
Alignment bracket locks the readhead to
the extrusion for transit
2 Semi-open
Readhead can be moved along the
extrusion for alignment purposes, whilst
maintaining optimum rideheight
3 Open
Alignment bracket can be removed from
the extrusion after installation
14.3 Alignment bracket method
Pre‑fitted alignment brackets help protect and secure the readhead to the extrusion during transit. These
alignment brackets can also be used to set the readhead at the nominal installation rideheight.
The alignment brackets have three different operating positions which are detailed in the table below.
