Edc on CAREL MPXPRO: meaning and checks

First checks, in order

The checks below are a REFTHE editorial path to compare with the machine diagram, configuration and manual.

1. Photograph the code and controller nameplate; record the phase of the cycle.
2. Compare the meaning with the manual revision and page shown on this sheet.
3. Only perform checks allowed by the diagram, manual and available competence; avoid repeated resets.

What the code does not prove

The code directs the investigation but does not, by itself, prove that a probe, valve, controller or other component is faulty.
