Typical Timing Diagram
Fig. 114: Timing diagram for SF_MutingSeq with S_StartReset = TRUE
The FB detects the following error conditions:
n Muting sensors MutingSwitch11, MutingSwitch12, MutingSwitch21, and MutingSwitch22 are activated in
the wrong order.
n Muting sequence starts without being enabled by MutingEnable
n A faulty muting lamp is indicated by S_MutingLamp = FALSE.
n A static Reset condition.
n MaxMutingTime has been set to a value less than T#0s or greater than T#10min.
n The muting function (S_MutingActive = TRUE) exceeds the maximum muting time MaxMutingTime.
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.
