For applications using a 0–10 VDC or 4–20 mA P499 transducer, you must:

  • change parameter values in Table 1
  • calculate and change P.902 and P.903 (for 0–10 V operation) or P.904 and P.905 (for 4–20 mA operation), based on the desired operating pressure range and motor speed for the condensing fans on your application. See VFD68Dxx Drives Operation Panel and VFD68Dxx Drive Parameters for more information.
