Troubleshooting

This section on troubleshooting is a guide to problems associated with the installation and integration of the system only. Refer to the 'PH10 PLUS installation and user's guide' (Renishaw part number H-1000-5070) regarding problems associated with normal operation of the system.

The optional HCU2 can also be used to identify system faults. For full details of the use and fault finding capability of the unit see the 'HCU2 hand control unit user's guide' (Renishaw part number H-1000-5361).

Use the table below 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.
