Apply an offset to Universal Inputs on the Xenta 102-AX

Issue

Apply an offset to Universal Inputs (U1, U3) on the Xenta 102-AX

Product Line

TAC Vista

Environment

Xenta 102-AX

Cause

Universal inputs U1, U3 on the Xenta 102-AX can be configured to read in several different data types.  Applying a software offset may be required to calibrate the reading for certain settings.

Resolution

For the following signals, use the listed SCPTs to offset the inputs:

  1. Universal Input 1 set to Duct Temperature use
    UnivIn1_Sense.SCPToffsetTemp
  2. Universal Input 3 set to CO2 Sensor use
    UnivIn3_Sense.SCPToffsetCO2
  3. Universal Input 3 set to OA Temp. Sensor use
    UnivIn3_Sense.SCPToffsetTemp

Hint:  For SCPToffsetTemp used with °F, first double-click the value to open the Edit Properties window and change the units to "°F, diff."  This will zero out the 32° offset and allow you to use the value as a temperature differential.
