Table 2-6: Custom Alarm and Saturation Values
Level
Low
High
Failure mode alarm and saturation levels can be configured using a Field Communicator,
AMS Device Manager, and the LOI. The following limitations exist for custom levels:
• Low alarm level must be less than the low saturation level
• High alarm level must be higher than the high saturation level
• Alarm and saturation levels must be separated by at least 0.1 mA (0.025 Vdc)
The configuration tool will provide an error message if the configuration rule is violated.
Note
Transmitters set to HART
digitally; saturation and alarm conditions will not affect the analog output. See also
