Troubleshooting a PXE 100 E-13 Error Code

Overview

The E-13 error code can display due to the pressure sensor voltage being low or nonexistent.

The control is looking for a pressure sensor input voltage range from +0.5 VDC (0 PSI) and +4.5 VDC (30 PSI).

This can be checked at the P5 connector (Velocity R/S Picture) on the control board between the Black (com) and White (DC + input to control).

Shock Hazard

HIGH VOLTAGE PRESENT! To avoid personal injury, this procedure should only be performed by a service technician who is trained and understands electrical safety.

Troubleshooting for Pressure Sensor Malfunctions:

Ensure all connections are plugged in as the transducer needs 5 vdc power supply to give an output back to the board. Checking at the back of the connectors at the board with meter leads is possible on all models and the best place to check.

E-13 A Pressure Sensor Failed

E-13A occurs when the control receives a low input voltage, less than +0.25 VDC. An E-13A error also occurs when the sensor fails to provide a voltage or is disconnected.

Confirm there is 5 vdc between Black (com) and Red (+vdc supply) to the transducer. If there is not, board may be faulty.
Check other VDC components for power.
Confirm we have at least 0.5 vdc between Black (com) and White (+vdc input to board) when there is 0 pressure on the system.

This may vary slightly as the oil in the unit may put a very small amount of pressure on the sensor.

The 0.5 VDC “0 PSI” number rises in correlation to the amount of pressure in the vat up to 4.5 VDC “30PSI” when there is product in unit and pressure in vat.
Confirm we have between .5 to 4.5 VDC voltage coming back to the board on the Black and White.
If there is enough voltage coming back to the board, the board is faulty. Refer to Replacing the Control Board.

E-13 B Pressure Sensor Failed

E-13B occurs when the control receives a high input voltage, more than +4.75 VDC. An E-13B error also occurs when the sensor has shorted to +5 VDC.

Use same troubleshooting as E-13A.
