UCC MMI-2 troubleshooting
UCC MMI-2 visual diagnostics
A visual indication of the system status is provided by two LEDs on the front panel, providing assistance in diagnosing and rectifying system faults.

|---|---|
 | LED on, displaying green, amber or red |
 | Red flash |
 | Green flash |
 | LED off |
Probe seated | Error | Description | Fault | Solution |
|---|---|---|---|---|
|  | Constant red error LED | Power fault/ FPGA reset | In the event of this fault, check the power supply or else, please return to Renishaw |
| | Intermittent fast flashing red error LED | Security validation failure | In the event of this fault, please return to Renishaw |
|
| Continuous fast flashing red error LED | Factory configuration | Application FPGA image must be re-programmed and if fails, return to Renishaw |
|
| Slow green flashing error and probe LEDs | Normal start-up operation, waiting for comms synchronisation | Situation occurs during startup, software comms synchronisation or lost comms with software |
|
| Probe LED constant green | No fault Normal operation | Probe seated, normal operation |
|
| Probe LED constant red | No fault Normal operation | Probe open, normal operation |
Fatal faults
Situations can occur that make it inadvisable or dangerous to continue using the CMM system. These are known in UCCsuite as fatal faults.
A list of UCC MMI-2 related fatal faults is shown below and will be indicated through the user's software (for example MODUS):
- Air pressure is too low
- A scale reading failure
- An indicated overspeed (calculated from the rate of change of position)
NOTE: Other faults not classed as fatal can prevent the CMM's operation.
If the fatal fault cannot be resolved, please contact your local CMM support centre who can advise.
