1)
Discrepancy time activated: The discrepancy timer starts on the first signal change that leads to a discrepant status.
Discrepancy time deactivated: The discrepancy timer is inactive. No timeout ever occurs.
2)
Unchanged = the last status is retained.
3)
If the dual-channel element adheres to the correct sequence.
Sequence error
A dual-c
hannel evaluation can only switch to Active (input changes in the logic from 0 to
1) if the following conditions are met:
•
The status was set to Deactivated at least once since it was last Active, i.e., it is
not possible to switch from Active to Discrepant and then back to Active.
•
The discrepancy time has either not yet elapsed or is deactivated.
If the correct sequence for achieving the Active status has not been observed, the
safety controller indicates a sequence error within a maximum of 100 ms.
Complementary information
Value range: 0 ms … 60 s
•
W
hen Discrepancy time is deactivated, the value is set to infinite.
•
If signals from tested sensors are connected, the discrepancy time must be
greater than the test pulse duration (ms) + the max. tolerated test pulse delay
(ms) of the safety capable input used.
•
A discrepancy error (timeout) is reset when the Disabled status is achieved.
