Ok, I'm at wits end with an ATS that I'm trouble shooting...
-Briggs and Stratton 200 Amp ATS with Service Disconnect and AC Control Module
connected to a 12 kw B & S Generator
- Utility power fails and switchs to gen and all is well, problem is Utility returns and ATS will not switch back to Utility. Control board LEDs indicate that both utility and gen power is present. Once Utility is restored the only way it will transfer back is shut Gen breaker of and it will switch back to Utility, other wise it will run Gen until fuel runs out
History- I got involved after a surge hit ATS and this started...I replaced control board and transfering mechanism (solenoids and all) due to obvious burn marks on both...only parts left were fuses and breakers and ct's...generator and 240 volt sensing circuit check out fine
I also installed a surge suppressor to help prevent future attacks from mother nature and the poco
What am I missing???
