12.9 Functions of the outputs
12.9.1 Functions of the BYPASSED and ON / RUN outputs
BYPASSED output contact
The BYPASSED output at terminal 23 / 24 closes as soon as the SIRIUS 3RW40 soft starter
detects that the motor has started up (refer to chapter Ramp-up detection [Page 104]). The
integral bypass contacts simultaneously close and the thyristors are bridged. The integral
bypass contacts and output 23 / 24 open again as soon as the start input IN is removed.
ON / RUN output contact
ON function set: The potential-free output contact at terminal 13/14 (ON) closes if a signal is
present at terminal 1 (IN); it remains closed until the start command is removed (factory
default). The ON function can be used, for instance, as a latching contact if you selected
pushbutton control (refer to chapter Control by pushbutton [Page 168]).
Reparameterizing the output of the ON function (factory default) to RUN
You can reparameterize the output function from ON to RUN by simultaneously pressing two
buttons (refer to chapter Parameterizing the 3RW40 outputs [Page 110]).
RUN function set: The potential-free output contact at terminal 13/14 closes if a signal is
present at terminal 1 (IN); it remains closed until the start command is removed and after that
until the set ramp-down time has elapsed.
If the RUN function is set, you can control a line contactor during the startup process,
operation, or the set soft stop (refer to chapter Control with an optional main / line contactor
