Pressure Transducer Wiring Change

05/06/2014

Franklin Control Systems has recently switched pressure transducer vendors. This switch has led to a slight change in our quickstart guide due to differing wire colors (new transducer has a black output wire, old transducer has a white output wire). The updated transducer wiring procedure is detailed below.

Pressure Transducer:

  1. Peel back insulation to expose shield (bare) wire. Note: Green & white wires should not be used.
  2. Wire the pressure transducer’s positive RED wire to the VFD terminal marked V+ for 12 VDC (“24” for 24 VDC) and the output BLACK wire to terminal I with the shield wired to:
    1. 5G for drives 40 hp or less
    2. CM on 50 hp and above
  3. For 24 VDC transducer setup, a wire jumper is required between CM and 5G.
