COMPRESSOR CODE 54
PT2, Regulation System Pressure Sensor Fault
PT2 Pressure Sensor Circuit:
Circuit Description:
The pressure sensor connects to the WEDGE controller as shown in the circuit
above. The purple WJDe is the 5 VDC excitation supply from the WEDGE. The
orange WJDe is the signal output to the WEDGE with a range of 0.5 to 4.5 VDC.
The brown WJDe is the sensor ground. The pressure range of PT2 is 0 psig (0.5
VDC) to 100 psig (4.5 VDC).
Component Location:
PT2 pressure sensor is located in regulation system on top of the separator tank.
Explanation:
The WEDGE has detected an out of range reading from the PT2 pressure sensor.
Effect:
Code 54 is an ALERT condition and will not stop the machine. The Compressor
Malfunction light will be blinking, and Code 54 will be displayed.
