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 110)). The
integral bypass contac
ts 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 176)).
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 116)).
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.
