The MK5 digital output (e.g., DO1 on connector CON2, pin 6) sends a 24V DC signal to the coil of K1. The return path goes through the overload relay’s normally closed (NC) auxiliary contact (terminals 95-96).
The Mk5 system generally separates wiring into two distinct categories: High Power (Power Circuit) and Low Power (Control Circuit).
Important Warning: Many unofficial websites offer low-resolution or incomplete diagrams. Using the wrong diagram can cause electrical fires or permanent controller damage.

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:
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.
The Atlas Copco Elektronikon MK5 is the brain of many modern industrial air compressors. This sophisticated controller manages everything from start/stop sequences and pressure regulation to remote communication and fault diagnostics. However, when the compressor malfunctions—be it a failed sensor, a stuck contactor, a blown fuse, or a communication error—service technicians and in-house maintenance engineers inevitably find themselves searching for one critical document: the Atlas Copco Elektronikon MK5 wiring diagram full schematic.
A "full" wiring diagram is not just a simple line drawing; it is a comprehensive map of every wire, terminal, relay, and electronic component inside the compressor’s control panel. Without it, troubleshooting becomes guesswork, leading to costly downtime. atlas copco elektronikon mk5 wiring diagram full
This article provides a deep dive into everything you need to know about the MK5 wiring diagram: what it includes, how to read it, common pitfalls, and where to find the official, full version.
Atlas Copco Elektronikon Mk5 wiring diagrams are complex technical documents that detail the electrical integration of the compressor's control system, including power supply, sensor inputs, and communication interfaces. Because these diagrams vary significantly based on the specific machine model (e.g., GA, VSD, or Scroll) and power rating (kW), they are typically organized into multiple sheets. Core Wiring Diagram Components
A standard full wiring set for an Mk5-controlled system generally includes the following sections: acprodbponlinebcc5.blob.core.windows.net Power Circuit (Main Motor & Dryer):
Details the primary power distribution, including the main motor and, if applicable, the integrated dryer circuit. Supply Control Circuit:
Shows the transformation of line voltage into the control voltage (often 24V or 110V) used by the Elektronikon regulator. Regulator Connections: Specific pinouts for either the Mk5 Graphic
versions, identifying where to connect pressure and temperature sensors. Digital & Analog I/O:
Diagrams for the 4–10 digital inputs and 4–7 analog inputs used for monitoring machine health and operational parameters. Communication Ports: Dedicated sections for the CAN connection Ethernet slot , and optional for Modbus/Profibus integration. Typical Terminal and Pinout Layouts
While specific pinouts depend on the unit, general guides identify several key terminal groups: www.e-pneumatic.com Voltage-Free Contacts: Open a technical support ticket
Used for remote signaling of general alarms, automatic operation, and service warnings. Pressure Sensing:
Terminals for the analog pressure transducers (typically 4-20mA or 0-5V signals). Remote Control:
Dedicated inputs for remote start/stop and remote load/unload functions. Emergency Stop (E-Stop):
A critical safety loop that must be correctly wired to prevent machine operation if broken. Integration and Connectivity
The Mk5 supports advanced networking via specialized modules: Gateway Module:
Requires specific wiring for Modbus or Profibus connections, often utilizing a bridge module to translate CANBUS data for external systems. SMARTLINK:
Embedded connectivity options allow for remote monitoring without extensive additional wiring, using the onboard Ethernet or cellular module. Reliable Sources for Full Diagrams

The Atlas Copco Elektronikon Mk5 is the standard controller for many of Atlas Copco’s popular oil-injected screw compressors (such as the GA series). Because it acts as both the user interface and the main processor for the machine, the wiring diagram is complex, typically spanning multiple pages in the official service manual.
Below is a comprehensive guide to the Mk5 wiring architecture, including common terminal layouts, voltage requirements, and safety precautions.
