ComAp controllers show this as a text alarm on the display, not as a numbered code.
Engine coolant temperature has reached the shutdown threshold. The ComAp controller has stopped the engine to prevent heat damage. Do not restart until the cooling system has been inspected and the cause determined.

Default high temperature shutdown is typically 100-105 deg C. Warning level is usually set 5-10 degrees below shutdown. Both are configurable in InteliConfig.
Fix the cooling issue first, then clear the alarm using the controller buttons or InteliMonitor software. The engine must be allowed to cool before resetting.
Send us the code or alarm and what the generator is doing, and one of our engineers will help you diagnose it.
