The Ultimate Guide to the Atlas Copco Elektronikon MK5: Obtaining, Reading, and Troubleshooting the Full Wiring Diagram

Introduction

For maintenance engineers, facility managers, and compressor technicians, the Atlas Copco Elektronikon MK5 is a familiar sight. As the brain of many Atlas Copco GA, GR, and other industrial air compressor models (from 7.5 kW to 355 kW+), this regulator controls everything from load/unload cycles to fault logs and network communication.

However, when a compressor flashes a "Motor Overload," a sensor fails, or a contactor refuses to pull in, you cannot rely on guesswork. You need the Atlas Copco Elektronikon MK5 wiring diagram full version.

This article serves as a complete resource. We will cover why you need the full diagram, the difference between the "user" diagram and the "full" electrical schematic, how to legally obtain it, a pin-by-pin breakdown of the MK5 controller, and common troubleshooting steps using the diagram.

Part 1: Why the MK5 Wiring Diagram is Critical for Your Compressor

The Elektronikon MK5 is not a simple on/off switch. It is a PLC (Programmable Logic Controller) with specific I/O (Input/Output) mapping. Without the full wiring diagram, you are blind to:

Safety circuit logic: Why does the emergency stop cut power to the coil of relay K21?
Analog sensor values: Which pins on the 37-pin D-sub connector carry the 4-20mA signal from the thermistor or pressure transducer?
Modbus communication: How do the RS-485 terminals (A/B) map to your building management system (BMS)?
Phase monitoring: How does the controller detect a phase sequence fault?

Searching for "Atlas Copco Elektronikon MK5 wiring diagram full" usually indicates you are past the basics. You have a multimeter in hand, and you are ready to trace wires, but you lack the road map.

Section D: High Voltage Motor Circuit (Not directly on MK5, but shown)

The diagram shows how the MK5 controls the main contactor (K21) via a 24V DC relay, but the 400V power to the motor runs separately through overload relay (F22).

Step 4 – Verify Wiring from the Full Diagram

Check if any intermediate components exist: a selector switch (S1) for manual/auto, or a remote emergency stop (S21). The full diagram shows every branching path.

Conclusion: If DI3 sees 0V, the MK5 registers a fault. The full diagram allows you to bypass sections methodically without shorting the wrong pins.

2.5 Sensor Wiring Details

The MK5 uses specific analog inputs:

PT100 temperature sensor – 3-wire configuration. The full diagram shows which wires go to pins A+, B+, and B-.
4-20 mA pressure transducer – 2-wire loop powered by 24V DC from the MK5.

Part 1: Understanding the Atlas Copco Elektronikon MK5 System

Before interpreting the wiring diagram, you must understand the MK5 architecture. The MK5 (Mark 5) controller consists of three primary hardware variants depending on the compressor model (GA, GX, ZR, ZT, etc.):

The MK5 Display Unit: The user interface with a keypad and LCD screen.
The Base Unit (CPU): The main processor located inside the electrical cabinet.
I/O Modules (Expansion Cards): Additional modules (e.g., IO 8, IO 4, IO 4R) that add inputs, outputs, and relays.

A full wiring diagram will show all three layers, including:

Power supply (input 115V or 230V AC, regulated to 24V DC).
Digital inputs (pressure switches, level sensors, emergency stops).
Digital outputs (contactor coils, solenoid valves).
Analog inputs (temperature sensors PT100/PT1000, pressure transducers 4-20mA).
Communication buses (CANbus between modules, RS-485 for remote control).

1. The Anatomy of the Diagram

Before diving into specific connections, it is vital to understand how Atlas Copco structures their schematics. The diagram is typically divided into functional blocks rather than a single, continuous circuit.

Power Circuits (High Voltage): Located usually on the left side or first pages. This includes the Main Motor (M1), Fan Motor (M2), and the Main Line Contactor (K1). These wires are thick and carry high amperage.
Control Circuits (Low Voltage): This is the brain of the system. It involves the Elektronikon Mk5 controller, relays (K-series), and fuses (F-series). These wires are typically thinner (0.75mm² to 1.5mm²).
Signal & Sensor Circuits: The nervous system. This includes temperature sensors (PT100/PT1000), pressure transducers, and level switches.

Warning on Third-Party Sites

Sites offering a "universal" MK5 wiring diagram are usually incorrect. The pinout on a 2005 MK5 (with a green screen) differs from the 2015 MK5 (with a white backlight). Always get the machine-specific version.
