4–20 mA P499 Transducer - PENN Controls - VFD68Bxx - VFD68Cxx - Three‐Phase Motor Speed Controller - VFD68 Three‐Phase Variable Frequency Drive

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 Configuring EXT Mode Using Analog Inputs)
• calculate and change the C x parameters based on the desired operating pressure range for the condensing fans on your application
