2.2 Operating modes
The static transfer switch STS is designed for the operating modes “inverter priority” and
“mains priority” alternatively. The consumer load is energized by the priority source as long as that
source works faultlessly.
REMARK: The unit's default setting is "Inverter priority".
The priority source is programmable using "service menu 2" (only available on request for qualified and
skilled service personnel).
2.2.1 "Inverter priority" (default setting)
At the operating mode “inverter priority” the load is switched on inverters during normal operation.
Source “Mains” only is required to energize the
consumer load if source “Inverter” fails or is overloaded
(i. e. distortions by short circuit behaviour or overload).
2.2.2 "Mains priority"
At the operating mode “mains priority” AC mains works as priority source and the inverter
(
as “substitute mains”) as source 2. The STS only switches to inverter(s) when mains failes.
