5.6 Functions of the outputs
SIRIUS 3RW30 / 3RW40
46 Manual, 10/2010, 535199502000 DS 03
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 110)).
The integral bypass co
ntacts 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.
