ComAp controllers show this as a text alarm on the display, not as a numbered code.
The ComAp controller has attempted to start the engine the configured number of times but the engine has not reached running speed. Further start attempts are locked out until the fault is cleared.

The default is typically 3 start attempts with a configurable pause between attempts. This can be changed in InteliConfig but should not exceed engine manufacturer recommendations.
If the engine cranks but doesn't start, check fuel delivery and speed sensor. The speed sensor must detect engine rotation for the controller to recognize a running engine.
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.
