Siemens SITRANS LR500 Series - Configuring Limit Monitoring; Configuring the Event Counter

Con󹪝guring limit monitoring
Procedure
1. Select the menu command "Device > Limit monitoring and event counter".
The "Limit monitoring" tabs are displayed.
2. To trigger a process value alarm each time the value falls below or exceeds the limit, set the
"Limit monitoring" text box to "Enabled".
3. Select the process value (e.g. sensor temperature) that you want to monitor from the
"Monitored value" drop-down list.
Con󹪝gure only one process value per tab.
4. In the "Upper limit", "Lower limit" and "Hysteresis" text boxes, enter the values that trigger an
event.
If the process value rises above the upper limit (overrun) or falls below the lower limit
(underrun), an event is counted based on the con󹪝gured value for the hysteresis.

Result
The process value alarm is displayed as a symbol for the status in the "Diagnostics > Device state"
dialog of the engineering system and on the device screen.
It is not necessary to acknowledge the process value alarms.
If the monitored process value is again within the limit values, the process value alarm is
reset.
