Protection of operating personnel and the system is only
ensured if the AS-Interface safety slave is used in
accordance with the usage for which it is properly intended.
The device can only be operated by trained professionals in
accordance with the available instruction manual.
It must only be used as a safety-oriented slave on an AS-
Interface line with a corresponding AS-Interface safety
monitor in accordance with the intended purpose.
The requirements for external cabling and selection of
connected sensors are based on both the functionality to be
fulfilled and the required category (EN 954-1/ISO 13849-1).
This category is determined either with the aid of risk
analysis (for example in accordance with EN 1050) or from
a C standard. The category of the safety monitor must
correspond at least to the category required by the
application.
The correct design of the desired safety function also
depends on the circuitry and programming of the safety
monitor. This also applies to the desired safety response
after a code malfunction or failure. See also the
documentation for the safety monitor and the section of
connection assignment. The safety function (including all
safety-related sensors) must be verified before the unit is
placed in service for the first time.
