Atlas Copco Elektronikon Mk5 Wiring | Diagram

For external communication, the Gateway acts as a "proxy," giving each compressor a unique address for data exchange.

MK5 allows pin reassignment via . The printed wiring diagram shows default assignments. If the controller was reconfigured, the diagram may be wrong.

The main contactor coil (A1/A2) must be wired in series with any external safety chain (e.g., door interlock, phase monitor). The diagram will show this interlocking clearly. atlas copco elektronikon mk5 wiring diagram

The Elektronikon Mk5 system typically consists of several interconnected circuits detailed in official service diagrams: For external communication, the Gateway acts as a

Distributes main power to the primary motor (M1) and the dryer (A1).

Contactor pulls in, motor runs for 0.5 seconds, then entire compressor goes dark. If the controller was reconfigured, the diagram may be wrong

+24V (X4.1) ---[Transmitter +]---[Transmitter -]---(X4.2) 4-20mA input to MK5

Digital inputs are typically on terminals . Each input expects a dry contact (voltage-free) signal.
