When searching for "Atlas Copco Elektronikon MK5 wiring diagram full," note the version.
If you install an MK5 from a fixed-speed compressor into a VSD compressor without the correct full diagram, you will blow the 4-20mA output card instantly.
Before reading the diagram, know the physical components:
The wiring diagram is a ladder-style schematic, not an electrical line diagram.
The Atlas Copco Elektronikon MK5 wiring diagram full document is not just a piece of paper; it is the definitive truth of your compressor's electrical system. Whether you are retrofitting a machine, fixing an intermittent communication fault, or replacing a failed contactor, that PDF is indispensable.
Remember: Always use the diagram specific to your machine’s serial number, respect the high-voltage sections, and digitally zoom into the 37-pin connector details—that is where 90% of MK5 problems hide.
If you are still stuck after reading your full diagram, check the Atlas Copco Service Bulletin S-2024-001 (MK5 pinout errata) or contact your local distributor with the drawing number in hand.

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 Atlas Copco Elektronikon Mk5 is a sophisticated controller used to manage and monitor compressor systems. While specific wiring diagrams are proprietary and vary by compressor model, the Mk5 follows a standardized architectural layout for its control and power circuits. Core System Architecture
The Elektronikon Mk5 typically divides its electrical system into several key sections as detailed in official service diagrams:
Main Power Supply: Standardized for specific motor data (e.g., 75kW variable speed motors).
Power Circuit: Includes the main motor and, if applicable, the dryer circuit. When searching for "Atlas Copco Elektronikon MK5 wiring
Control Circuit Supply: Powers the Mk5 Graphic or Touch regulator.
Input Connections: Features multiple digital and analog inputs (typically 4-10 digital and 4-7 analog) for sensor data. Standard I/O and Port Specifications
The Mk5 Graphic and Touch units utilize a specific set of terminals for hardware interfacing:
Digital Inputs/Outputs: Used for status monitoring (e.g., Running, Power On) and fault alarms (e.g., Service Needed).
Analog Inputs: Dedicated to monitoring real-time variables like outlet pressure and temperature.
CAN Ports: Standard interface for interconnecting different compressors or controllers in a network.
Ethernet & RS485: Used for communication protocols such as Modbus RTU and connecting to remote monitoring systems. Installation & Wiring Requirements
Proper setup requires strict adherence to safety and environmental standards:

Title: Understanding the Atlas Copco Elektronikon Mk5 Wiring Diagram: A Comprehensive Technical Guide
Introduction
The Atlas Copco Elektronikon Mk5 control system is a workhorse in the industrial compressed air sector. Renowned for its reliability, it manages compressor operation, monitors system health, and optimizes energy efficiency. However, when a compressor fails or an upgrade is required, the wiring diagram becomes the most critical document in the maintenance engineer’s toolkit.
This article serves as a detailed guide to understanding the Elektronikon Mk5 wiring diagram. We will break down the layout, decode common terminal designations, and explain the flow of power and signals within the cabinet.
| Signal | Sensor type | MK5 terminal | Wiring | |--------|-------------|--------------|--------| | Air pressure (P1) | 4-20mA | X3:1 (+) , X3:2 (-) | 2-wire loop powered by MK5 24V | | Air temp (T1) | PT100 (3-wire) | X3:3 (red), X3:4 (red), X3:5 (white) | RTD input | | Oil pressure (P2) | 0-10V | X3:6 (signal), X3:7 (GND) | 3-wire sensor |
Important: The MK5 diagram specifies sensor type in the parts list. Do not substitute a 0-10V sensor for a 4-20mA input without reprogramming.
Important Warning: Many unofficial websites offer low-resolution or incomplete diagrams. Using the wrong diagram can cause electrical fires or permanent controller damage.
The MK5 safety circuit is redundant and failsafe:
+24V DC → -S14 (E-stop NC) → -F11 (Overload NC) → X1:DI4 (MK5 input)
If E-stop pressed or overload trips, MK5 sees 0V on DI4 → immediate shutdown.
Also shown: Hardwired safety relay (-K50) that cuts contactor coil supply independently of MK5 software (redundant path).
It is vital to distinguish between the standard user manual and the full electrical schematic.
| Feature | User Manual (Generic) | Full Wiring Diagram (Machine-Specific) | | :--- | :--- | :--- | | Pinout of MK5 | Basic layout (X1, X2) | Detailed voltage levels (24V DC, 110V AC, 230V AC) | | Relay Assignments | "Relay 1 = Alarm" | Which internal relay (K1-K8) controls the drain valve via Pin 14 | | Transformer Taps | Not shown | Exact secondary voltages (e.g., 0-15V for fan, 110V for logic) | | External Interlocks | Mentioned | Specific terminal blocks (TB1, TB2) for remote start/stop | | Component IDs | General | Atlas Copco part numbers for contactors (K21, K23) and fuses (F1, F2) |
Key takeaway: The "full" diagram is serial number specific. An Elektronikon MK5 on a GA 37 VSD works differently than one on a GA 90 FF. If you install an MK5 from a fixed-speed
