• Open: APM continues to track failure statistics and the PF interval (if appropriate) for the failure.
• Resolved: Statistics and the PF interval (if appropriate) are no longer calculated.
• Canceled: Statistics and the PF interval (if appropriate) are no longer calculated.
• Total: the asset’s performance has decreased to a point where the asset is no longer performing at its required level. The asset has completely failed.
• Partial: the asset’s performance has decreased to a point where it is no longer performing one of its functions at the specified levels. The asset is still functioning.
• Potential: a condition that has been noticed that would result in an actual failure if the problem is not resolved. The actual failure has not yet occurred. Potential failures are normally reported as the result of an indicator reading that has raised a warning alarm against the asset.
The PF interval indicates the remaining time until a potential or partial failure escalates to a full failure. PF interval can be tracked in terms of time or a cumulated indicator value such as cycles or operating hours. The Indicator based option is available only if the asset has been assigned a cumulative indicator.
