Configuration
The transmitter automatically and continuously performs self-diagnostic routines. If the self-diagnostic
routines detect a failure, the transmitter drives the output to configured alarm and value based on the
position of the alarm switch. See “Setting transmitter alarm” on page 39.
Table 2-4. Rosemount Alarm and Saturation Values
Table 2-5. NAMUR-Compliant Alarm and Saturation Values
Table 2-6. Custom Alarm and Saturation Values
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
The configuration tool will provide an error message if the configuration rule is violated.
Note
Transmitters set to HART multidrop mode send all saturation and alarm information digitally; saturation
and alarm conditions will not affect the analog output. See also “Establishing multidrop
communication” on page 24.
