8.6 Manual start circuit
▶
Connect S34 to A1 via a button or an enabling contact or use a PLC out-
put for control.
Monitoring of input S34 prevents the enabling current paths from closing in
the following situations:
•
Digital input S34 at HIGH level when switching on the power supply.
•
Digital input S34 does not switch to LOW level on demand and before
the set delay time has elapsed.
•
Digital input S34 at HIGH level when closing the emergency stop cir-
cuits.
•
Manual and automatic start circuit simultaneously at HIGH level.
Figure 15: Manual start circuit
￫
After the emergency stop, the enabling current paths close
automatically when the emergency stop circuits are closed.
This also applies if the emergency stop circuits are closed
before the delay time has elapsed.
