5.6 Functions of the outputs
5.6.1 3RW30: Output terminal 13 / 14 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.
The output can be used, for instance, to control a line contactor connected upstream or to
implement latching if you selected pushbutton control. For recommended circuits, refer to
chapter Typical circuit diagrams (Page 175).

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 105)).
