OFF-DELAY FUNCTION
After the supply voltage is applied to terminals A1/A2 and the
safety inputs are closed, the enabling current paths (NO contacts)
are closed automatically or by pressing the reset button (manual
start). When the safety inputs are opened/de-energized the
enabling current paths (NO contacts are opened immediately or
with a delay).
• Automatic start – Reset input S14 is connected to safety input
S12. To monitor external contact blocks (EDM), their NC contacts
must be connected in series between S34 and S12.
• Manual start without monitoring – Reset input S14 is connected to safety input S12 via a reset button. To monitor external
contact blocks (EDM), their NC contacts must be connected in
series to the reset button.
• Manual start with monitoring – Reset input S34 is connected to
safety input S11 via a reset button. To monitor external contact
blocks (EDM), their NC contacts must be connected in series to
the reset button.
