Performance Level, design examinations etc.
The safety structure and functionality of the PROTECT-PSC system complies with
PL e, Category 4 to ISO 13849-1.
In accordance with the above requirements a prototype test was performed for the
PROTECT-PSC system by the Institut für Arbeitsschutzder Deutschen Gesetzli-
chen Unfallversicherung, IFA, St. Augustin/Germany (Institute for Occupational
Safety).
By way of information:
The above prototype test confirms a degree of safety for the PROTECT-PSC
system comparable with PLe, Category. 4 to ISO 13849-1, also for emergency
actions within the meaning of IEC 60204-1 point 9.2.5.4. Refer also to chapter
2.2.5
The ISO 13849-1 is a standard within the meaning of MRL article 5 point 1 para-
graph 2. See also chapter 2.2.3.
Use of electronic equipment for safety functions.
“. This means that when using
electronic equipment the so-called presumed effect of harmonised standards is not
completely available.
In Germany, there should not be any problems with employer’s liability insurance
associations, technical inspectors or technical supervisory agencies with regard to
the use of electronic equipment with safety functions. The same applies to the
majority of other EU member states.
However, it cannot completely be ruled out at the present time that there may be
acceptance problems in isolated cases with respect to the use of electronic
equipment for safety functions. Please consult us if this is the case. Refer also to
chapter 2.2.5
The internal structure of the PROTECT-PSC system corresponds to PL e,
Category 4 according ISO 13849-1 (see above). However, the performance level
actually achieved in the entire safety circuit (refer to figure below) and thus the
degree of safety attained will similarly depend on the structure of the input and
output circuitry.
