Issue: 2 wire, 4-20mA transducer wiring.
Product line:Altivar ATV61 and ATV71
Environment:All models, all serial numbers
Cause: A 2 wire transducer needs to be wired to the drive for a pressure feedback signal.
Resolution:Wire the 2 wire transducer as follows:
The input of the transducer typically requires 24Vdc. This may be wired to the VFD terminal +24 or to an external power supply.
The output of the transducer is wired to the VFD terminal AI2.
Program the AI2 Configuration for 4-20mA. See attached file.
