02250071-151 Controller Panel For Sullair Air Compressor

The Sullair Controller, part number 02250071-151, is a critical Genuine OEM component belonging to the advanced V-Plus (Versatility) control platform. Designed as the central command unit for Sullair rotary screw air compressors, this controller manages all critical logic, including modulation control, safety shutdowns, and system diagnostics.

Engineered for the high-demand LS series compressors, the 02250071-151 replaces outdated or failed control boards, instantly restoring the compressor's ability to communicate with operators and optimize energy usage.

Enhanced Diagnostics: The V-Plus platform provides sophisticated fault detection, identifying issues ranging from minor warnings to critical shutdowns, which simplifies troubleshooting for technicians.

Energy Efficiency: Optimizes the compressor's loading and unloading cycles (or dual-control modes) to reduce energy waste, providing cost savings for the end-user.

User-Friendly Interface: Features a clear, logical display (depending on the specific assembly) that allows operators to easily navigate menus, adjust pressure setpoints, and view maintenance timers.

Durability: Built to withstand the electrical noise and thermal stress typical of compressor rooms, ensuring a long service life and reducing replacement frequency.

Direct Replacement: Ideally suited for Sullair LS-10, LS-12, LS-16, and LS-20 series stationary rotary screw compressors (commonly 150HP, 175HP, 185HP, 200HP, and 250HP models).

Industrial Manufacturing: Maintaining precise air pressure control for automated assembly lines, metal fabrication, and general plant air systems.

Heavy Duty & Construction: Suitable for harsh industrial environments where robust electronic control is required to withstand heat and vibration.

Safety Warning: Installation involves handling sensitive electronics. Always disconnect the main power supply and verify zero voltage (Lockout/Tagout) before opening the control cabinet.

Preparation:

Access the compressor electrical control panel.

If the old controller is still functional, record the critical settings (e.g., Pressure Setpoints, Language, Auto-Off Timer) from the display.

Label all wires and connector plugs to ensure accurate reconnection.

Removal of Old Unit:

Carefully disconnect the ribbon cables and terminal blocks from the existing V-Plus controller.

Remove the mounting screws/clips securing the unit to the backplate or cabinet door.

Remove the old controller carefully.

Installation of New Controller (02250071-151):

Mount the new controller into the control panel door or backplate.

Reconnect all wiring harnesses, ensuring the connectors are fully seated and locked.

Grounding: Verify that the grounding strap or screw is tightly connected to prevent Electrostatic Discharge (ESD) damage to the new board.

Configuration & Start-up:

Restore power to the compressor.

The controller will perform a self-test upon boot-up. The screen should illuminate.

Parameter Entry: Enter the "Settings" menu (password protected). Input the specific parameters required for the compressor model (e.g., Load Pressure, Unload Pressure, Dual Control settings).

Date & Time: Set the current time to ensure accurate maintenance logs.

Final Verification:

Run the compressor and monitor the display for correct pressure and temperature readings.

Simulate a fault condition (if safe) or observe a load cycle to ensure the control logic responds correctly.

Check for any active error codes.
