Compliance for the MatGuard control unit is achieved with the requirements
of a category 3 per EN ISO 13856-1, PLd per ISO 13849-1, and SIL 2 per IEC 62061
regarding reliability and electrical faults and can be met for the associated part
of the machine control system. Compliance with the requirements of
EN ISO 13856-1 category 1 is achieved for the safety mat sensors.
The type of safeguarding system must be suitable for the application for which
it is intended. A documented process of risk assessment of the machinery or
process reveals the identity and nature of the hazards together with other
relevant information. The machinery manufacturer must conduct a risk
assessment to determine the PL or SIL requirements. The characteristics of the
safeguarding system must then be compared with the results of the risk
assessment to determine whether the risk can be reduced to an acceptable
level. On some applications, to achieve an acceptable level of risk, it can be
necessary to combine multiple types of safeguarding systems.
