Upgraded 1900071271 Elektronikon I Plus Controller Panel For Atlas Copco Screw Compressor

Product Introduction

Smart start-stop logic and clear machine diagnostics live in one compact brain. 1900071271 (1900-0712-71, Elektronikon I+) is a main controller panel for Atlas Copco small-to-mid screw air compressors. It manages motor start/stop, load/unload pressure bands, monitors discharge temperature and system pressure, logs faults and service hours, and supports RS485 plant communication with optional SMARTLINK remote view.

Aging or wrong-firmware units cause blank LCD, stuck keys, lost parameters, false alarms, or no-start. During replacement: cut control power, photo all connectors, swap the old 1900071271, restore wiring exactly, power on, load correct GA/GX program by machine serial and pressure setting, verify readings. Supplier must preload software before shipping — not plug-and-play across all variants.

Also called regulator, computer board, HMI controller, Elektronikon I+ panel, compressor brain.
