The Atlas Copco Elektronikon Mk5 (or Mark V) controller is a sophisticated unit used to manage and monitor compressor systems. Full wiring diagrams for these units are typically model-specific and included in the technical documentation for the specific compressor (e.g., GA series).
Below is a breakdown of the typical wiring and connection structure for the Mk5 controller based on standard service diagrams and manuals. Core Wiring Categories
A complete Mk5 wiring setup is usually divided into several functional circuits:
Main Power Supply: Standard connections for 3-phase power to the main motor and any integrated dryer units.
Control Supply: Powering the regulator itself, often involving a transformer to step down voltage for the MK5 module.
Input Connections: Dedicated terminals for analog and digital inputs, such as pressure sensors, temperature sensors (PT1000), and emergency stop buttons.
Output Connections: Relay or digital outputs that control the loading/unloading solenoid valves and main motor starters. Terminal and Port Overview
The Mk5 Graphic and Touch models typically feature the following input/output (I/O) capabilities: Graphic Model Touch Model Digital Inputs Analog Inputs Digital Outputs Communication Ethernet, CAN, RS485 Ethernet, 2x CAN Communication and Networking
For advanced monitoring or multiple compressor setups, the Mk5 uses specific networking protocols:
CAN Network: The primary internal network for connecting different Elektronikon controllers or expansion modules.
Modbus/Profibus: Often requires a dedicated Gateway Module inserted into the CAN network to act as a proxy between the compressor and a master control system.
Ethernet: Modern Mk5 Touch units include a dedicated Ethernet slot for direct connection to local networks. Safety and Installation Precautions Elektronikon Mk5 Modbus/Profibus Guide | PDF - Scribd
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.
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. Once you have the authentic PDF, it looks overwhelming
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
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.
Official Documentation: For exact pinouts related to your specific serial number, consult the Atlas Copco Instruction Books or professional engineering resources like Scribd.
