Option: Automatic Transfer Switch(ATS)
ATS automatic control panel include mains power indicator, generator operation indicator, auto-mode status indicator and fault alarm indicator.
When the ATS detects that the mains power is cut off, the generator set automatically self-starts and the ATS closes generator circuit (loads powered by generator). When ATS detects mains recovery, generator enters cooldown shutdown (30-60 min delay) and ATS opens generator circuit (loads transferred to mains).
