Activates the fan based on temperature. 4. How to Read the Full Wiring Diagram
A critical rule of the Elektronikon Mk5 wiring architecture is the strict physical and electrical separation between high-voltage power circuits and low-voltage control circuits. High-Voltage Control Circuits (115V – 230V AC)
Understanding the terminal blocks on the back of the Elektronikon Mk5 (or its auxiliary I/O modules) is the first step in decoding the full wiring schematic. While specific pinouts can vary slightly depending on whether the compressor is a GA, ZR, or ZT series, Atlas Copco follows a standard terminal categorization system. Power Supply Connections (24V DC / AC)
Atlas Copco Elektronikon Mk5 is a sophisticated compressor controller designed for advanced monitoring and system protection. Its wiring architecture typically consists of several standard sheets covering main power, control circuits, and sensor inputs.

The Mk5 features heavy-duty relay outputs used to switch inductive loads via interposing contactors. Energizes the main motor starter.
Includes the main drive motor connections, fan motors, star-delta starters, or Variable Speed Drive (VSD) inverters.
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 controller, was silent. Activates the fan based on temperature
Always ground the shielding braid of analog cables at the controller end only . Grounding both ends creates a ground loop, introducing electrical noise into sensor readings.
If your Elektronikon Mk5 displays a sensor fault, communication error, or fails to load, use this systematic approach alongside your full schematic: Step 1: Verify Input Power
Each I/O module (X1, X2, etc.) has:
This is perhaps the most critical output. When energized, it allows the compressor to load and produce air. When de-energized, the compressor runs in unload mode.
If equipped with a ComBox module, you will find terminals for A (-) , B (+) , and Shield . Proper shielding must be grounded at one point only to prevent ground loops. 5. Step-by-Step Troubleshooting Using the Wiring Diagram
Usually routed through a step-down transformer to provide safe control voltages. If equipped with a ComBox module
