For applications using a 0–10 VDC P499V Transducer, you must:

  • adjust the parameter values that are listed in Table 1
  • ensure that the AI2 mode switch (Figure 1) is set correctly
  • calculate and change C x parameters based on the desired operating pressure range for the condensing fans on your application
The VFD68 has the ability to control motor speed using the higher input signal value of two voltage inputs when you configure AI1 and AI2 as the same model transducer. For the high-input signal select application with two transducers (Figure 1 or Figure 1), use the parameter values in Table 1 and see Figure 1 in VFD68Bxx and VFD68Cxx Drive Basic and Advanced Parameters, and Adjusting the Default Parameters.
