PV Engineering Unit Conversions

You can initiate manual engineering unit conversions for PV value used in displays by substituting appropriate converted values for PVEUHI and PVEULO on page one of the Detail display. Use the Y = mX+B formula explained in Section 4 of the PM/APM Smartline Integration Manual to calculate the desired PVEUHI and PVEULO values. LRV and URV are used as “X” in the formula. Tables A-9 through A-12 list conversion values that can be used for “m” and “B” in the equation to calculate a desired PV value.

ATTENTION

As a shortcut, you can use the “built-in” conversion available for PV1, PV2, and PV3 by changing the STI_EU parameter and using the values displayed.
