The Atlas Copco Elektronikon Mk5 (Mark V) is a sophisticated controller used across a wide range of Atlas Copco industrial air compressors, including the GA, Z, and VSD series. Understanding its full wiring diagram is essential for installation, troubleshooting, and integrating the compressor into a plant management system. Core Wiring Layout of the Elektronikon Mk5
The wiring for the Mk5 is generally divided into several primary circuits:
Main Power Supply: Connects the compressor to the plant's electrical grid. Common voltages include 380V, 400V, or 460V at 50/60Hz.
Main Motor Circuit: Controls the primary motor (M1) and includes protection components like fuses (e.g., IEC gL/gG or UL Class CC) and phase sequence relays (K25).
Control Supply Circuit: Often uses a 24VDC supply (U2) to power the Elektronikon module and associated sensors.
Integrated Dryer Circuit: For models with an integrated refrigerant dryer, this separate circuit controls the dryer motor and solenoid valves (Y2). Key Input and Output Connections
The Elektronikon Mk5 typically features a standard set of I/O terminals for machine monitoring and control: Connection Type Standard Count Common Uses Digital Inputs
Emergency stops, remote start/stop, and load/unload commands. Analog Inputs
Pressure transducers (outlet pressure) and temperature sensors (element outlet). Digital Outputs

The hum of the factory was a living thing, but today, it had a stutter. Elias, the head technician, stood before the GA75 compressor, its interface glowing with a cryptic fault code. The heart of the machine, the Elektronikon Mk5 controller, was silent. Part 3: How to Read the Atlas Copco
He cracked the heavy steel cabinet door. Inside was a labyrinth of silicon and copper. To the untrained eye, it was a mess of gray wires and terminal blocks; to Elias, it was a logic puzzle waiting to be solved. He reached for his tablet and pulled up the full wiring diagram.
The digital blueprint blossomed across the screen. He traced his finger along the CAN-bus lines—the nervous system that allowed the Mk5 to speak to the sensors. “You’re not talking,” he muttered, his eyes darting between the screen and the physical 1X1 and 1X2 terminal strips.
According to the schematic, the 24V power supply should have been jumping from terminal 15 to the digital input modules. He pulled his multimeter, the leads sharp and silver. Zero volts.
He traced back further on the diagram, bypassing the emergency stop circuit and the fan motor starters, until he landed on the transformer secondary. There, tucked behind a bundle of neatly zipped ties, was a single wire—labeled Wire 2002—that had vibrated loose from its housing. It was a tiny break in a massive system, a silent disconnect that had paralyzed the entire production line.
With a flick of his wrist and a tightening of a terminal screw, the circuit was restored.
Elias stepped back and pressed the ‘Start’ button. The Mk5 screen flickered, ran a self-diagnostic, and then the familiar, rhythmic pulse of the compressor roared back to life. On the screen, the pressure bar began to climb.
He closed the cabinet, the wiring diagram still glowing on his tablet—the map that had led him home through the copper woods.
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.

Let’s walk through a practical example: Troubleshooting a “Motor Overload” fault on a GA 37 VSD compressor.
2.1 Terminal Block Designations (X1, X2, X3...)
Each physical terminal inside the cabinet is assigned a code. For example:
- X1:1 – Mains power input (L1)
- X1:3 – Neutral (N)
- X2:10 – Emergency stop loop (digital input)
- X3:5 – Air demand pressure switch
A full diagram lists every terminal down to the pin level on the controller’s rear connectors (CON1, CON2, CON3, etc.).
Section B: The MK5 Power Connector (X1 – 7 pins)
- Pin 1 & 2: 24V DC input from transformer rectifier.
- Pin 3: 0V DC (Ground reference for sensors).
- Pin 4 & 7: Internal relay outputs (e.g., Fan control to contactor K22).
