There might be two reasons for the failure of generator auto start.
1. It is the ATS automatic conversion control device that does not issue the start generator command after the mains power failure or phase loss operation, or the self-starting relay failure, which causes the generator to not start itself. This situation is relatively rare.
2. It is the generator start battery failure, and this kind of situation is relatively more.

I would think the coolant level safety feature triggers the fault and /or parameters set up or programming.
