Forced dynamisation:
When monitoring sensors with square output signals (TTL, HTL) or safe sensors, the axis
must be moved within 8 hours so that the signal changes on all the connected tracks.
If forced dynamisation of the signals cannot be carried out every 8 hours, then the average
frequency of a dangerous failure (PFH) is increased.
If the forced dynamisation time is increased, the stated PFH value must be multiplied by the
following correction factors:
Forced dynamisation within 4 weeks → Correction factor 1.01
Forced dynamisation within 8 weeks → Correction factor 1.02
