Process alerts allow for the configuration of the ERS system to output a HART
message when a parameter (such as the measured DP) exceeds a
2, 3
user-defined operating window. An alert will be communicated to the HART
host (such as a Field communicator or AMS), when polled, and on the LCD
display of the ERS system. The alert will reset once the value returns within
range.
Process alerts may be configured for the following parameters:
• Differential Pressure
• P Pressure
HI
• P Pressure
LO
• P Module Temperature

• P Module Temperature
LO
Configuring Process Alerts
1. Select a parameter for which the process alert will be configured.
2. Set the Alert Mode to "enable."
3. Define the Low Alert Value. If the measured value for the parameter goes
below the Low Alert Value, an alert message will be generated.
4. Define the High Alert Value. If the measured value for the parameter
goes above the High Alert Value, an alert message will be generated.
