Conversion for PV4
Engineering unit conversion for PV4 must be done manually if you want to
display PV4 flow calculation in units other than cubic meters per hour.
The engineering unit description is entered in the EUDESC parameter in
the PED. Then you enter LRV and URV in the detail display for PV4.
Next calculate the conversion factor for PVEULO and PVEUHI
parameters.
To calculate use the formula: Y = mX + B
Where: Y is the conversion factor (the result of the calculation that
you enter as the PVEVLO or PVEUHI parameter in the
detail display.)
m is the conversion multiplier (from table) for the selected
engineering units.
X is either LRV or the URV.
B is the conversion offset (from table) for the selected
engineering units.
Enter conversion factor as PVEULO parameter.
