Figure 1 - The MRS modular rack system
Introduction
The stylus change port (SCP600) is a modular system, designed to allow
automatic stylus changing on a CMMs, for the SP600 analogue probe.
The primary purpose of the SCP600 is to improve flexibility with the ability to
use and store longer styli and large star styli configurations.
The SCP600 ports are designed to be fitted onto the Renishaw modular rack
system (MRS).

Troubleshooting
Fault Possible cause Solution
Lid failing
to close
Guideway
obstructed.
Spring failure.
Examing the guideway and remove any
obstruction.
Examine the springs and ensure that they
are connected to the respective holding
pins within the assembly.
If a spring has failed, or is missing, spring
replacement kits are available from your
local Renishaw company or supplier.
Alternatively, return the unit to your local
Renishaw service centre to have new
springs fitted.

Datuming the SCP600
NOTE: As the SCP600 port is of modular design, it is suggested that the
following routine is completed under manual control for each port installed.
The following section describes the recommended procedure for datuming
the SCP600 once it is fitted to the MRS rail and on the CMM table. In
addition, the following method assumes that the SCP600 port is aligned to
the CMMs axis with a maximum run out of 2.5 mm across points A and B
(see figure 3). If required, please refer to ‘Fitting the SCP600 to the MRS rail’
earlier in this document. The recommended procedure to locate the port is
as given below (please refer to figure 3):
1. Push the lid [2] of the SCP600 port [1] to the extreme of travel (this
assumes that the SCP600 is connected to the MRS system at the time).
2. Place the stylus tool [3] into the retaining hole at the rear of the
SCP600 port [1].
3. Release the SCP600 lid [2] so that the stylus tool [3] holds the lid.
4. Take 4 points on the top face of the docking plate [4] (plane 1).
5. Take 4 points in the circle at the rear of the SCP600 port docking
plate [4] (circle 1).

Fitting the SCP600 to the MRS rail
It is recommended that the SCP600 ports are attached to the MRS rail using
the following procedure where it is assumed that the MRS system is correctly
installed. For full details, please refer to the MRS modular rack system
installation and user’s guide (H-1000-5088):
1. Insert one of the fixing screws [1] through the SCP600 port [2] as
shown in figure 2.
2. Offer up the SCP600 port [2] to the MRS rail [3], positioning the fixing
screw [1] to the respective ‘T’ bolt within the rail. Finger-tighten the
screw.
3. Insert the other fixing screw [1] through the SCP600 port [2] as shown
in figure 2.
4. Position the SCP600 port so that the second screw locates into the
respective ‘T’ bolt in the rail. Finger-tighten the screw.
5. Using the hexagonal key supplied, hand-tighten the two fixing screws
[1] into the ‘T’ bolts.
