11 Troubleshooting

This section on troubleshooting is a guide to problems associated with the installation and integration of

the system only. Section 4 of the PH10 series user’s guide (Renishaw part number H-1000-5070) deals

with problems associated with normal operation of the system.

The optional HCU1 can also be used to identify system faults. For full details of the use and fault ﬁnding

capability of the unit see the HCU1 hand control unit user’s guide (Renishaw part number H-1000-5016).

Use table 25 to identify problems you are experiencing with your system. If you experience problems

which you are not able to identify or solve satisfactorily, please contact Renishaw for further advice.
