Individual Sensor/Dry Contact Pages
A sensor's or dry contact's data/setup page is opened after clicking any sensor or dry contact name on the Peripheral
Devices page. See
(on page 56).
Note that only a numeric sensor has threshold settings, while a state sensor or dry contact has no thresholds.
Threshold settings, if enabled, help you identify whether any numeric sensor enters the warning or critical level. See
Yellow- or Red-Highlighted Sensors
(on page 62). In addition, you can have the PDU automatically generate alert
notifications for any warning or critical status. See
Configuring a Numeric Sensor’s Threshold Settings
