Creating an Out of Range Alarm
You create an out of range alarm to trigger an alarm when a variable, such as a temperature, is not within its specified range.
When setting up an out of range alarm, you configure the normal range of the monitored variable. If the variable goes below the lower limit or above the upper limit of the normal range, the alarm is triggered.
For example, you set up an out of range alarm that monitors the temperature in a server room. The alarm is triggered when the temperature goes outside the range of 20 °C to 25 °C (68 °F to 77 °F).
You can configure out of range alarms using shunt variable, time delay, and deadband. 有关更多信息，请参阅 Alarm Functions .
