: The Mk5 module typically requires a 24VAC / 16VA supply.
Atlas Copco provides the electrical schematic free of charge to registered owners. You only need to log in with your compressor’s serial number.
Once you have the authentic PDF, it looks overwhelming. Here is how to read it using standard IEC symbols. atlas copco elektronikon mk5 wiring diagram full
While the MK5s (Mark 5s) has a different display, the base wiring is 80% identical if you use the official conversion diagram. The full original MK5 diagram serves as the baseline.

Measure the voltage across the main power input terminals. Ensure it matches the rating plate specification (typically 24V) and is stable when the compressor contactors pull in. Step 2: Diagnose Sensor Failures (e.g., "Sensor Error")
: Tied to dedicated 3-wire analog inputs providing 4–20 mA current loops or 0–10V signals for monitoring element discharge and line pressure.
