For applications using a 4–20 mA P499A transducer (Figure 1), you must:

  • set P.266 and P.267 to 0
  • set the AI2 mode switch position to I (see VFD68Bxx and VFD68Cxx Drives)
  • calculate and change the C x parameters based on the desired operating pressure range for the condensing fans on your application
