The wiring diagram for an Atlas Copco Elektronikon Mk5 controller generally spans multiple schematic sheets, covering everything from the main power supply to specific digital and analog input/output (I/O) connections.
While specific terminal numbers can vary based on your machine's model (e.g., GA series vs. Scroll) and power rating, the following breakdown represents the standard full-text architecture found in official service diagrams. 1. Power and Supply Circuits
Main Power Supply: Connects to the primary voltage (e.g., 380V-460V) with dedicated grounding and short-circuit protection via IEC gL/gG or UL Class CC/T fuses.
Control Supply (24VAC/DC): The Mk5 module typically requires a 24VAC / 16VA supply.
Phase Sequence Relay (K25): An optional component often integrated into the power circuit to protect the motor from reverse rotation. 2. Controller I/O Terminals
The Mk5 Graphic and Touch units typically feature a set number of inputs and outputs: GA18 - 30 - VSDplus - Electrical - Service - Diagram - Mk5S
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 For a full wiring diagram of the Atlas

The Atlas Copco Elektronikon Mk5 is the central control unit for modern industrial air compressors, serving as the "brain" that manages motor operation, energy efficiency, and system diagnostics. A full wiring diagram for this controller typically encompasses the main power supply, control circuits, and a specific array of input/output (I/O) connections tailored to the compressor model. Core Wiring Components
Official service diagrams for the Mk5 system are structured into several critical sheets:
Main Power Supply: Maps the incoming voltage and frequency requirements.
Motor Data & Power Circuit: Details the wiring for the main motor (M1) and, if applicable, the integrated dryer.
Control Circuit Supply: Outlines the low-voltage power path to the regulator itself.
Regulator Connections: Specific pinouts for the Mk5 Graphic or Mk5 Touch interfaces. Input and Output (I/O) Specifications
The Elektronikon Mk5 features a robust set of connections to monitor and control the compressor's environment:
Digital Inputs: Typically 4 to 10 inputs for monitoring discrete states like emergency stops or pressure switches.
Analog Inputs: Typically 4 to 7 inputs for continuous data like temperature and pressure sensors.
Digital Outputs: Usually 6 to 9 outputs to trigger contactors, solenoid valves, or alarms.
Connectivity Slots: Includes dedicated ports for Ethernet, CAN, and sometimes an SD card slot for data logging or firmware upgrades. Communication and Networking
For advanced system integration, the Mk5 supports industrial protocols:
Modbus & Profibus: Integration requires a specific gateway module inserted into the CAN-based network, allowing the compressor to act as a proxy with its own unique address.
Remote Monitoring: Connectivity via Smartlink or Ethernet allows for real-time trending and predictive maintenance. Installation and Safety Guidelines Group A: Mains Supply & Digital Inputs
Grounding: A low-resistance connection (maximum 20cm wire length) must be made between the controller’s earth terminal and the enclosure chassis. Use M4 eye-terminals or FASTON receptacles for shielding and grounding.
Protection: The system must be earthed and protected by fuses in all phases, with a lockable power isolating switch nearby.
