and fault signals [Page 44].
5.6.2 3RW40: Output terminals 13 / 14 ON / RUN and 23 / 24 BYPASSED
ON
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.
Reparameterizing from ON to RUN
You can reparameterize the function of the ON output on the 3RW40 to RUN by
simultaneously pressing the RESET TEST and RESET MODE buttons (refer to chapter
Commissioning the 3RW40 [Page 98]).
RUN
The RUN output remains closed as long as the motor is controlled by the soft starter, in other
words during the startup phase, in bypass mode, and during the soft stop (if set). This output
function can be used, for instance, if a line contactor connected upstream must be controlled
by the soft starter, especially if the soft stop function is set.
BYPASSED
The BYPASSED function can be used, for instance, to indicate that the motor has started up
successfully.
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.
