DBX108.7 NC Ready
Edge evaluation: no
Signal state 1 or The control system is ready.
edge change 0 → 1
This interface signal is an image of the relay contact "NC Ready".
This signal is set if:
•
•
•
Signal state 0 or The control is not ready. The relay contact "NC Ready" is open.
edge change 1 → 0
The following faults will cause NC Ready to be canceled:
•
•
•
If the signal "NC Ready" goes to 0 the following measures are introduced by the control if they are
still possible:
•
•
