Fig. 105: Timing diagram for SF_MutingPar
The FB detects the following error conditions:
● DiscTime11_12 and DiscTime21_22 have been set to values less than T#0s or greater than
T#4s.
● MaxMutingTime has been set to a value less than T#0s or greater than T#10min.
● The discrepancy time for the MutingSwitch11/MutingSwitch12 or MutingSwitch21/MutingS-
witch22 sensor pairs has been exceeded.
● The muting function (S_MutingActive = TRUE) exceeds the maximum muting time
MaxMutingTime.
● Muting sensors MutingSwitch11, MutingSwitch12, MutingSwitch21, and MutingSwitch22 are
activated in the wrong order.
● Muting sequence starts without being enabled by MutingEnable.
● A faulty muting lamp is indicated by S_MutingLamp = FALSE.
● A static Reset condition is detected in states 8001 and 8003.
Error behavior In the event of an error, the S_AOPD_Out and S_MutingActive outputs are set to FALSE. The
DiagCode output indicates the relevant error code and the Error output is set to TRUE.
A restart is inhibited until the error conditions are cleared and the safe state is acknowledged
with Reset by the operator.
