Setting Thresholds
The Thresholds feature enables you to set thresholds for analog and digital inputs and to configure the frequency that Email, Combination, FTP, Output and Report to File actions are processed against the threshold. The EVR1500 environmental monitor appliance handles up to 25 thresholds.
The threshold information shown in Figure 4.1 is used to monitor a temperature probe connected to an analog input. The threshold will monitor the selected analog input (Analog_in01) every 60 seconds. If the value of Analog_in01 meets or exceeds 85 degrees F, the selected Combination action (Combo_Action1) will execute. The Combination action will execute one time and then wait for the release value to reset. Once it is reset, the action will execute again if 85 degrees F is exceeded. A threshold action is reset when the temperature sensor first reports an input voltage that is less than the release value of 75 degrees F. Once the temperature has dropped below 75 degrees F, the action is reset.
