Additional installation content for a multiple readhead system

9.1 Mounting the encoder

The encoder is available with up to eight readheads for Biss Safety systems and up to five
readheads for Siemens DRIVE-CLiQ systems.
For mounting surface preparation and mounting orientations refer to the FORTiS-S FS enclosed
encoder system Functional Safety installation guide and safety manual (Renishaw part no.
M-6725-9016).
For minimum distances between readheads and permissible cable orientations refer to the system
installation drawing; see section 9.3 on page
NOTES:
1. It is the responsibility of the installer to ensure that readheads and their connected cable
assemblies do not meet with each other or collide with end caps.
2. Typically, for applications that require multiple readheads traversing a single extrusion, the
extrusion is fixed with only the readheads moving. Please contact your local Renishaw
representative if your requirements are different.
3. Some of the shorter measuring lengths will not support multiple readheads, depending on
number of readheads, cable configuration and cable type. Please discuss with your local
Renishaw representative.

9.2 Connecting the air supply

For fixed extrusion installations as described (see note in section
connected to the extrusion only.
Air inlets are included in each end cap, at both ends of the extrusion. Use a suitable air supply hose
with a 4 mm bore.
For compatible air supply components refer to the data sheet Air filtration systems for use with
FORTiS encoders (Renishaw part no. L-9517-9982).
WARNING: Remove the blanking plug only from the position at which the purge air supply is to be
connected, or the sealing integrity may be compromised.
