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 |
