Onan RSS 200 Amp Automatic Transfer Switch: Click Here for Specification Sheet Click Here for Owners Manual LED lights indicate system status Start time delay: Three seconds (prevents nuisance generator set starts during momentary utility power variations) Transfer time delay: Three seconds (allows generator set to stabilize before load is applied) Retransfer time delay: Adjustable or Ten minutes (prevents needless power interruption if return of utility power is momentary Stop time delay: Adjustable 0-30 minutes, default 10 minutes (allows gradual generator set cool down) Undervoltage sensing: All phases on the normal source and single phase on generator source. Normal source pickup: adjustable 70-90% of normal voltage; Generator source pickup: 90%, dropout: 75% of normal voltage.   Integrated 6 amp automatic battery charger Includes selectable 7, 14, 21 or 28 day exerciser clock (factory set at 28 days) Push buttons allow for operation from ATS control panel Two poles Voltage: 120/240V, 1 ph UL 1008 listed/CSA certified
