SIDOOR ATD410W/ATD420W/ATD430W
The system responds to faults according to the sequential control (see Image 6-33
Sequential control state graph (Page 216)). After acknowledgement, the controller
automatically triggers a reset after a protection time of 5 s.
Fault acknowledgment
Fault acknowledgement can take place in relation to one of the following three possibilities:
●
Corresponding terminal input prompt
●
FBLOCK "fault acknowledgement" *
●
Corresponding acknowledgment bit (bit 7) in STW1 (see Section TSW1 - technology
control word 1 (Page 206)) *
