Connected to the auxiliary contacts of the thermal overload relays.

With a flick of his wrist and a tightening of a terminal screw, the circuit was restored.

The Elektronikon MK5 is a state-of-the-art compressor controller developed by Atlas Copco, a leading manufacturer of compressed air systems. This controller is designed to provide precise control over the compressor's operation, ensuring optimal performance, energy efficiency, and reliability. The MK5 controller features a user-friendly interface, advanced monitoring capabilities, and seamless communication with other Atlas Copco systems.

For accurate system schematics or persistent technical problems, you should contact Atlas Copco directly if:

Emergency Stop (E-Stop) loop, motor overload trip status, phase sequence relay, and manual remote start/stop switches.

Never run low-voltage sensor lines inside the same plastic wire ducting as high-voltage motor supply lines. Maintain a minimum separation of 100mm (4 inches) wherever possible, crossing paths only at 90-degree angles.

The back pane of the Elektronikon Mk5 features dense terminal strips classified by signal type to minimize electrical interference. Power Supply Terminals

Energizes the loading valve to compress air; de-energizes to run the machine in idle mode.

If you install an MK5 from a fixed-speed compressor into a VSD compressor without the correct full diagram, you will blow the 4-20mA output card instantly.

Improper wiring of an Elektronikon Mk5 can lead to erratic behavior, false trips, or permanent hardware damage. Follow these execution steps:

Let’s apply the diagram to real-world repairs.

Your full diagram uses these standard IEC symbols:

Regularly check and retighten terminal connections inside the cubicle. Loose connections generate localized heat and introduce intermittent logic faults.

This section connects the Main Motor and Fan Motor to the contactors/soft starter. The Mk5 controller usually provides the to the coils of these main contactors, but it does not handle the high voltage (e.g., 380V–480V) directly.

The Mk5 microprocessors are highly sensitive to static electricity. Ground yourself before touching terminal blocks or internal circuit cards.

Optional expansion boards (like the i01 and i02 modules) that scale up the number of connectable sensors and relays.

The is the current generation of compressor controllers, featuring advanced monitoring, energy-saving algorithms, and integrated connectivity via Smartlink , Modbus , and Profibus .
