Luxury 88290021-398 EC2000 Main Controller Panel For Sullair Screw Compressor

Product Introduction

Complete machine intelligence and operator control live in one dependable panel. 88290021-398 is an EC2000 deluxe controller panel for Sullair rotary screw air compressors. It runs start/stop and load/unload logic, displays pressure, temperature, run hours and fault history on a backlit LCD with keypad, handles safety interlocks, maintenance reminders, and supports Modbus/RS-485 multi-unit sequencing.

A failing panel shows blank screen, unresponsive keys, lost parameters after power cycle, false overtemp/overload alarms, or no-start. Surges, humidity, or wiped firmware are typical causes. During replacement: cut main power, photo and label all terminals, swap the old 88290021-398, restore wiring exactly, power on, load machine-specific firmware/parameters (supplier usually preloads by nameplate), and verify live readings. Always send machine serial + nameplate before shipping — not fully plug-and-play.

Also called computer board, PLC controller, HMI panel, EC2000 brain.
