DSE controllers show this as a text alarm on the display, not as a numbered code.
Engine oil pressure has dropped below the shutdown threshold and the DSE controller has stopped the engine to prevent damage. This is a critical protection fault. Do not attempt to restart until the oil pressure issue is diagnosed and resolved.

Do not restart until diagnosed. Check oil level first and add if needed. If oil level is correct, the sensor may be faulty - verify with a mechanical gauge before condemning the engine.
Typical diesel generators should maintain 30-60 PSI (2-4 bar) at operating temperature. DSE shutdown threshold is usually set around 10-15 PSI (0.7-1.0 bar).
Send us the code or alarm and what the generator is doing, and one of our engineers will help you diagnose it.

A fault code names a symptom, not a cause. Our engineers have written the diagnostic sequence they use on site for this class of fault — ranked causes, ordered steps with the reading expected at each one, and the point at which to stop and call someone.
