Feedback loop/delay time

Terminals Y6 and Y7 are used to connect the feedback loops and also to define the delay
time of safety output 24.
Connect feedback loop:
The unit has two feedback loop inputs, one (Y6) for safety output 14 and one (Y7) for safety
output 24:
}
Safety output 14 (instantaneous):
Connect the contacts from external contactors to terminal Y6.
}
Safety output 24 (delayed):
Connect the contacts from external contactors to terminal Y7.
}
Both safety outputs instantaneous or both safety outputs delayed:
Connect the contacts from both external contactors in series to terminal Y6 or Y7.
}
Feedback loop unconnected:
If you do not wish to connect any contacts to the feedback loop, Y6 and Y7 must be
connected to A1 or S11/S21, depending on the required delay time.

21236-EN-06
Automatic start
NOTICE
With a delayed safety output 24, operation of the start button is saved.
If the safety function is cancelled while the delay time is running (e.g. safety
gate closed) and the start button is operated, then the unit will be active im-
mediately once the delay time has elapsed.
NOTICE
With automatic start
The unit starts up automatically when the safeguard is reset, e.g. when the
E-STOP pushbutton is released. Use external circuit measures to prevent
an unexpected restart.
