B14: Universal Nodes

Configure

Most fields in the Node Configuration page are identical to the other nodes . There are two differences. The unit value limits must be defined and there are no critical alarm limits. 

The “Measurement Unit” and Max/Min “Unit Value” are the limits of the sensor* being used. Since the Universal Node can be used with any sensor of standard output 4- 20mA, 0-5V, or 0-10V, there are multiple different ranges that can be used. The sensor will output a signal which is received by the SensoScientific Universal Wi-Fi Node. This value is received, recorded, and transmitted to the cloud. The value received is in the form of the data output (voltage or current). To convert the transmitted value into a measured quantity, the unit minimum and maximum values of the sensor (see the sensor’s manual) must be inserted in the Node Configuration. 

For example, a differential pressure sensor with a range of +/-0.25 in. W.C. is used; therefore, the “Maximum Unit Value” is 0.25, the “Minimum Unit Value” is -0.25 and the unit type is also entered as in. W.C. in “Select Measurement Unit To Be Displayed”. With this example, the system alarms when the differential pressure is below 0 in. W.C. (“Minimum Alarm Limit”) or is higher than 0.20 in W.C. (“Maximum Alarm Limit”). 

If the differential pressure goes out of the specified range, the 1st alarm will trigger after 30 minutes (“Alarm Delay In Minutes”), as long as the condition doesn't correct itself. If the alarm is not confirmed, the system will send reminder alerts two (2) times until the alarm has been corrected (“Re-Alarm Delay In Minutes”). Once all the information has been entered, click “save” and the screen will go back to the “Registered Nodes” window and the configured node will show the updated settings.
