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.
