Logic programming – Function blocks
 When an override input is configured, test pulse outputs may not be used for the
configuration of the safety inputs.
 Separate lines have to be used for the sensor signals A1 and A2 (B1 and B2).
 A line that is independent of other input signals has to be used for the signals for
Reset and Reset required in order to exclude unintentional resetting of the system.
The line must furthermore be laid protected.
 The total muting time cannot be set to indefinite (inactive) without additional
precautions being taken. If the total muting time is set to indefinite, additional
measures have to be taken to ensure that no one can access the hazardous area
while muting is activated.
