system to a transmitter in an alarm state.
2.8.6 Process alerts
Fast Keys
Process alerts allow the user to configure the transmitter to output a HART message when
the configured data point is exceeded. Process alerts can be set for pressure, temperature,
or both. A process alert will be transmitted continuously if the pressure or temperature set
points are exceeded and the alert mode is ON. An alert will be displayed on a Field
Communicator, or AMS Device Manger status screen. The alert will reset once the value
returns within range.
Note
HI alert value must be higher than the LO alert value. Both alert values must be within the
pressure or temperature sensor limits.
Field Communicator
To configure the process alerts with a Field Communicator, perform the following
