The function of the safety unit meets the requirements of the following standards:
ƒ Category 4 and PL e according to EN ISO 13849-1
– To comply with category 4, the external wiring and the cable monitoring must
meet the requirements of category 4.
– Ensure that short circuits cannot occur in the external wiring.
ƒ SIL 3 according to IEC 61508
– The safety unit does not contribute to the probability of failure on demand (PFD)
and probability of failure per hour (PFH) of IEC 61508.
