Atlas Copco Compressor Fault Code 1554 File

The emergency stop circuit on an Atlas Copco compressor is a "closed loop" design. This means a continuous 24V DC (or 110V AC, depending on model) signal must flow through the entire safety chain. If that signal breaks anywhere, the compressor triggers fault 1554.

If you are operating an Atlas Copco GA (or similar oil-injected screw compressor) and the display suddenly shows Fault Code 1554 , your machine has likely tripped due to an Element Outlet Temperature that is too high . This is a critical safety shutdown designed to prevent damage to the airend (screw element). atlas copco compressor fault code 1554

: Once the maintenance is performed, the service counter must be reset in the controller (like the Elektronikon or XC4004 ) to clear the 1554 alert.

If you have replaced the oil, filters, and cleaned the cooler and the code persists, the Airend (screw element) may be failing mechanically (worn bearings causing internal friction). Contact a certified Atlas Copco service technician for a vibration analysis. If you are operating an Atlas Copco GA

While the definition of the code is straightforward (safety circuit open), finding where the circuit is open can be challenging. Here are the most frequent culprits:

Once the necessary maintenance is performed, the code must be cleared through the controller interface. For many Atlas Copco models:
