MaxMutingTime input

Specification of the maximum permissible time for the entire muting operation. If the muting operation is not completed within this time, the S_AOPD_Out output is switched to the defined safe state SAFEFALSE and the function block signals an error (Error switches to TRUE).

Data type: TIME
Initial value: #0ms

Connection: Connect this input to a time literal, i.e., to a constant of the data type TIME.

The following is valid for a material flow direction from left to right:

This timer starts when at least one muting sensor of the first parallel sensor pair (in this case, input S_MutingSwitch11 or S_MutingSwitch12, sensor located before the safety-related equipment) provides a SAFETRUE signal (i.e., there is an object inside the detection area of the sensor).
The muting operation is complete when at least one muting sensor of the second parallel sensor pair (S_MutingSwitch21 or S_MutingSwitch22, sensor located behind the safety-related equipment) provides SAFEFALSE again.

WARNUNG

Non-conformance to safety function requirements

Verify that the time value set at MaxMutingTime corresponds to your risk analysis.

Be sure that your risk analysis includes an evaluation for incorrectly setting the time value for the MaxMutingTime parameter.

Validate the overall safety-related function with regard to the set MaxMutingTime value and thoroughly test the application.
