: Energizes to open or close the inlet valve mechanism, switching the physical compressor state from "unload" to "load".

Relays and Contactors (Main motor, loading, fan, etc.). P1: Pressure Sensor/Transducer. Y1 / Y2: Solenoid Valves (Loading/Unloading, Drain Valves). B1 / B2: Temperature Sensors. 3. Elektronikon Mk5 Pinout and Input/Output Mapping

Always isolate and lock out the main power supply to the compressor before opening any electrical enclosure.

Never touch terminals without verifying with a multimeter that the system is de-energized. atlas copco elektronikon mk5 wiring diagram full

Start with the power source (3-phase input), through the main circuit breaker (Q1), to the main motor contactors ( KMcap K sub cap M

This indicates a network communication issue. Begin by visually inspecting all network cables and connectors for damage. Check for loose connections at the controller and any gateway modules. If the issue persists, an authorized technician should test the integrity of the network.

Ensure you understand the symbols for motor contactors, thermistors, and safety switches. 4. Common Troubleshooting Scenarios Using the Diagram

The Elektronikon MK5 is a microprocessor-based controller designed to manage and monitor the operation of Atlas Copco compressors. Its primary functions include: This public link is valid for 7 days

Monitor the lubrication circuit health. Digital Inputs (Status & Interlocks)

X1:3 → -Y1 means terminal 3 on I/O module X1 connects to solenoid valve Y1.

Tied to specific communication terminals labeled A (+), B (-), and COM.

The overload trip signal is sent to the MK5 digital input DI3 (e.g., CON3, pin 2). On the diagram, you will see a dashed line indicating that the overload relay’s NC contact is wired between the MK5’s 24V out (COM) and DI3. Can’t copy the link right now

Whether you are a seasoned field service engineer or a plant maintenance technician, treat the MK5 full wiring diagram as you would a treasure map. Follow it precisely, respect the voltage markings, and your Atlas Copco compressor will deliver reliable performance for years to come.

When working with the Elektronikon MK5 wiring diagram, it is essential to follow proper safety procedures to avoid injury or damage to equipment:

Critical for safety; measures the air temperature leaving the compressor element.

Check if the Elektronikon display status reads "Loaded". If yes, measure the voltage at the output terminal leading to Y1.

Connects to the regulated AC control voltage (typically 24V AC or 115V/230V AC depending on the specific module variants). Neutral (N): The return path for the AC supply.
