10.2
Fault management
Faults
Faults are all arising system faults that need acknowledgement.
You will find a list of faults in the Section Operating state display (Page 273).
SIDOOR ATD410W/ATD420W/ATD430W
The system responds to faults according to the sequential control (see Figure 4-4 Sequential
control state graph (Page 149)). 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 287)) *
* SIDOOR ATD410W/ATD420W/ATD430W
