Atlas Copco Elektronikon Mk5 Wiring Diagram Full [upd]
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.
Reverse the A and B data lines to check for polarity issues. Check for 120-ohm resistance across the unpowered bus. Open circuit in the safety loop.
Wiring typically involves a 2-wire or 3-wire configuration connecting the discharge pressure sensor and element outlet pressure sensor to the dedicated analog input channels.
The MK5 digital output (e.g., DO1 on connector CON2, pin 6) sends a 24V DC signal to the coil of K1. The return path goes through the overload relay’s normally closed (NC) auxiliary contact (terminals 95-96). atlas copco elektronikon mk5 wiring diagram full
The Elektronikon Mk5 is powered by low voltage to protect its internal circuitry.
This approach ensures you get the accurate and safe information required for your specific equipment.
While not always industry-standard, official full diagrams include wire colour codes (e.g., BK=black, BU=blue, RD=red) and cross-sectional area (e.g., 0.75 mm², 1.5 mm²). This is critical when repairing cut or burnt wires. This section connects the Main Motor and Fan
