UCC BI visual diagnostics

Visual diagnostics - front panel with zoom - UCC BI

A visual indication of the system status is provided by three LEDs on the front panel, providing assistance in diagnosing and rectifying system faults.

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.

Fatal faults

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)
  • PICS_STOP

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.
