Ri interface
Approved ESD precautions must be
followed at all times during readhead
and interface electrical connections.
The readhead is connected to the Ri interface via a
small, rugged connector to allow for easy feed-through
during installation.
NOTE: An optional Ri cable guide (A-9693-2577)
is available to simplify assembly.
For instructions on how to install the Ri cable guide,
download Ri interface cable guide (Renishaw
part no. M-9770-9478) from the website at
www.renishaw.com/atomdownloads
Connecting the readhead
1.
Open the interface housing by
removing the two screws shown.
(4-40 UNC screws and nuts)
2.
With the plain side facing up,
remove the top half of the
housing, so that the interface
PCB is exposed and the
readhead connection socket
is visible.
3.
Taking care not to touch the pins,
plug the connector into the socket
in the interface, ensuring correct
orientation as shown.
NOTE: Care is required to hold
the assembly together as the
PCB is fixed only to the 15-way
connector and the jack screws
are loose.

4.
Re-assemble the housing ensuring
the cable ferrule is located in the
recess on the inside and no wires
are trapped.
5.
Refit the screws.
6.
When the system has been
connected, proceed with
'Readhead mounting and alignment', page 23
and
'System calibration', page
Disconnecting the readhead
