Used for internal communication between the Mk5 display unit and input extension modules or the VSD frequency inverter. Requires twisted-pair, shielded cabling.
Must feature a at both physical ends of the bus line to prevent signal reflection. Modbus / Profibus / Ethernet Connections
Focus on the 24V DC or 110/220V AC supply that powers the MK5 display and sensors.
Check the wiring on the input terminals mentioned in the wiring diagram. Use a multimeter to verify 4-20mA signals. atlas copco elektronikon mk5 wiring diagram full
Activates the fan based on temperature. 4. How to Read the Full Wiring Diagram
The (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).
: Includes 4–10 inputs for remote start/stop, emergency stops, and alarm resets. Used for internal communication between the Mk5 display
: The system must be earthed and protected by fuses in all phases, with a lockable power isolating switch nearby.
Wired as a normally closed (NC) circuit. If the circuit opens, the controller instantly cuts power to the safety relays.
The is the current generation of compressor controllers, featuring advanced monitoring, energy-saving algorithms, and integrated connectivity via Smartlink , Modbus , and Profibus . A full wiring diagram for this system typically spans multiple sheets, covering main power supply, control circuits, and sensor inputs.

The Mk5 controller requires a stable power source to function. This is typically stepped down via an internal isolation transformer.
A hardwired, normally closed (NC) loop. Opening this circuit immediately drops power to the main contactor.
Below is a comprehensive guide to the Mk5 wiring architecture, including common terminal layouts, voltage requirements, and safety precautions.
Connects the main controller to auxiliary modules or variable speed drive (VSD) inverters. 2. Deciphering the Wiring Diagram Layout
