|---|---|
Power loss | Check mains cable connections and integrity. Check power block is supplying 24 V. Check CMM emergency stop condition - power may have been removed by CMM. |
No head movement in automatic mode
Possible cause | Solution |
|---|---|
Head controller in manual mode. | Change to automatic mode. |
Power loss | Check mains cable connections and integrity. Check power block is supplying 24 V. Check CMM emergency stop condition - power may have been removed by CMM. |
Cable / connection fault | Check connection and integrity of cabling between head and controller. |
Communications failure | Check RS232 baud rate. |
Incorrect command set selected | Check correct command set is selected. |
PICS STOP is asserted by other system component | Clear the fault asserting PICS STOP. |
No head movement in manual mode
Possible cause | Solution |
|---|---|
Head controller in automatic mode. | Change to manual mode. |
Power loss | Check mains cable connections and integrity. Check power block is supplying 24 V. Check CMM emergency stop condition - power may have been removed by CMM. |

No probe output signal received by the CMM computer
Possible cause | Solution |
|---|---|
Cable / connection fault | Check connection and integrity of cabling between head and controller. Check connection and integrity of cabling between controller and interface. Check connection and integrity of cabling between interface and computer. |
Multiwire bypass connector not fitted | Fit a multiwire bypass connector with will permit a standard touch-trigger probe signal to reach controller |
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
Possible cause | Solution |
|---|---|
Loose head mounting | Ensure all mounting screws are tight and that mounting to the CMM is secure. |
Probe incorrectly attached | Remove probe and reattach. |
Force applied to head during lock up | Lock and unlock the head. |
Incorrect lock up position | Reposition head correctly. |
Position not qualified | Check qualification information. |
