Elektronikon Atlas Copco 1900 0701 23 Controller

The Elektronikon Atlas Copco 1900 0701 23 is a high‑range regulator controller for extended air compressors, powered by 24 VAC (≈9 VA) with 250 VAC/10 A relay outputs and optional dual 7:10 A or 8:16 A contacts. Common failures include degraded power supply components, worn relay contacts causing intermittent operation, and loss of the embedded control program or firmware corruption. For a first‑check diagnosis verify the 24 VAC input voltage and continuity to the controller board, inspect the relay terminals for corrosion or mechanical wear, and review any displayed error codes or diagnostic LEDs on the panel.[oss-gpt-20b] Post Comment
