UCC BI visual diagnostics
A visual indication of the system status is provided by three LEDs on the front panel, providing assistance in diagnosing and rectifying system faults.
LED status key
LED on, displaying green, amber or red
NOTE: The following light patterns apply when using UCCsuite version 5.3 and onwards.
|Servo status||Probe seated||Error|
Amplifier not engaged
Security failure (fast green flash)
Firmware error (intermittent fast green flash)
** Controller not connected, waiting for download, download failed, device not recognised by UCC firmware or device not recognised by UCC downloadable software
Amplifier not engaged: E-STOP active or amplifier fault
Amplifier not engaged: E-STOP not pressed and amplifier has no fault
Probe not seated
NOTE: ** A slow flash synchronised with the controller's slow flashing status LED indicates that the UCC BI is correctly connected to the controller and that the controller is waiting for a software download.
Situations can occur that make it inadvisable or dangerous to continue using the CMM servo system. These are known in UCCsuite as fatal faults.
A list of the main UCC BI related fatal faults is shown below and will be indicated through the user's software (for example MODUS):
- A report of the emergency stop switch being active
- Air pressure is too low
- Crash switch operated, if fitted
- A scale reading failure
- An indicated overspeed (calculated from the rate of change of position)
- Outer limit switch active
- Digital SPA engage relay fault (when a safety relay in the SPA2-2 is detected to be stuck)
- Amp fault (when the SPA2-2 has a fault, which includes emergency stop active)
NOTE: Other faults not classed as fatal can prevent the CMM's operation.
