PHC10-3 Troubleshooting
This section on troubleshooting is a guide to problems associated with the installation and integration of the system only. Refer to the 'PH10 series user's guide' (Renishaw part number H-1000-5070) regarding 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 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.
Observation | Possible cause | Checks / remedies |
POWER ON LED not lit | Power loss | Check mains cable connections and integrity Check power block is supplying 24V Check CMM EMERGENCY STOP condition - power may have been removed by the CMM |
No head movement in automatic mode | Power loss | See above |
No head movement in automatic mode | Cable/connection fault | Check connections and integrity of cabling between head and PHC10-3 |
No head movement in automatic mode | Communications failure | Check RS232 baud rate |
No head movement in automatic mode | Incorrect command set selected | Check correct command set is selected |
No head movement in manual mode | Power loss | See above |
No head movement in manual mode | Cable/connection fault | Check connections and integrity of cabling between head and PHC10-3 |
No output signal received by the CMM computer | Cable/connection fault | Check connections and integrity of cabling from: Head to PHC10-3 PHC10-3 to interface Interface to CMM computer |
No output signal received by the CMM computer | Multiwire bypass connector not fitted | When using standard touch-trigger probes, the probe head multiwire bypass connector must be fitted to permit the probe signal to reach the PHC10-3 |
No output signal received by the CMM computer | Multiwired probe in use | Check that the multiwire cable is correctly fitted to the head Check that the trigger output to the CMM computer is connected to the multiwired probe interface |
Poor measurement performance | Loose mounting of head | Ensure all mounting screws are tight and mounting to CMM is secure |
Poor measurement performance | Probe damping enabled during measurement | Ensure probe damping is not enabled during measurement moves |
