Expansions are easily possible through the subsequent
adding of modules. The innovative plug-in technology also
does away with the wiring needed up to now. Through the hot
swapping function (disconnection and connection during
operation) a motor starter can be replaced within seconds if
necessary, without having to shut down the ET 200pro station
and with it the process in the plant. The motor starters are
therefore recommendable in particular for applications with
special demands on availability. Storage costs are also opti-
mized by the low level of variance (two units up to 5.5 kW).
With four locally acting inputs available on the High Feature mo-
tor starter it is possible to realize autonomous special functions
that work independently of the bus and the higher level control
system, e.g. as a quick stop on gate valve controls or limit posi-
tion disconnectors. In parallel with this, the states of these inputs
are signaled to the control system.
