Atlas Copco Elektronikon Mk5 Wiring Diagram Full May 2026
If the compressor is a VSD (Variable Speed Drive) model, the Mk5 wiring changes significantly.
The Atlas Copco Elektronikon MK5 wiring diagram full is more than a maintenance document—it is the single source of truth for electrical troubleshooting, modification, and safety compliance. Without it, a simple loose wire can escalate into a week of downtime.
Action Steps for Every Compressor Owner:
Whether you are a seasoned field service engineer or a plant maintenance technician, treat the MK5 full wiring diagram as you would a treasure map. Follow it precisely, respect the voltage markings, and your Atlas Copco compressor will deliver reliable performance for years to come.
Disclaimer: Electrical work should only be performed by qualified personnel. Always isolate and lock out the mains supply before opening the control panel. This article is for informational purposes. Refer to your machine’s official Atlas Copco documentation for exact wiring.
The Atlas Copco Elektronikon Mk5 is a comprehensive compressor controller featuring a full-color graphic display, advanced energy-saving algorithms, and integrated connectivity via SMARTLINK. Its electrical wiring is organized into several distinct circuits, typically spanning 10 or more detailed service sheets. Core Wiring Components
A full Mk5 wiring diagram typically includes the following major sections:
Power Circuit (Main Motor & Dryer): Detailed schematics for the main motor supply, including dryer settings and fuse requirements (e.g., IEC aR or UL Class T). atlas copco elektronikon mk5 wiring diagram full
Supply Control Circuit: Covers the primary 24VDC supply and transformer connections that power the controller itself.
Regulator Terminals (Mk5 Graphic/Touch): The physical connection points for the controller’s main unit, including grounding (earthing) requirements. Input/Output Connections:
Analog Inputs: Typically supports 7–10 inputs for pressure and temperature sensors.
Digital Inputs: Includes 4–10 inputs for remote start/stop, emergency stops, and alarm resets.
Digital Outputs: Features 6–9 relay outputs for solenoid valves and status signaling. Full Feature List (Mk5 vs. Legacy)
The "Long Feature" Mk5 offers significant technical upgrades over older MK1–MK4 models:

The Mk5 system generally separates wiring into two distinct categories: High Power (Power Circuit) and Low Power (Control Circuit).
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.
If you do not have the original diagram for your serial number, do not guess – wiring a 24V sensor to a 230V output will destroy the MK5 board (non-repairable, >$2000 replacement). Always verify wire colors and terminal numbers against the factory schematic.
