Following SOP of CNS 2901, CNS 10204.
Approval criteria apply to fire services emergency generator 3 ,440 Vac Max., 60Hz, 1750Kva Max.
 
Automatic start test is according to CNS 10204-780622 version sec 2.5.
 
Operation method: Using moving-head switch simulation for a signal of ATS start, turn auto position on control panel. Turn on moving-head switch to count up the built-in time between receiving signal and boosting voltage up.
