- 1h - OK - element is installed and no error conditions are known
- 2h - critical - critical condition is detected
- 3h - noncritical (warning) - noncritical condition is detected
- 4h - unrecoverable - unrecoverable condition is detected
- 5h - not installed - this element is not installed in the enclosure
- 6h - unknown - sensor has failed or element status is not available
