Important:
Ì The user is responsible for the integration of the device into a safe overall
system. For this purpose, the overall system must be validated, e.g. in ac-
cordance with EN ISO 13849-2.
Ì Correct use requires observing the permissible operating parameters (see
Technical data).
Ì If a product data sheet is included with the product, the information on the
data sheet applies in case of discrepancies with the operating instructions.
Ì In the estimation of the PL for the overall system, a maximum value of
100 years can be assumed for the MTTF
d
according to the limit value in
EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum
value for the PFH
d
of 2.47 x 10 -8 /h. When up to 11 devices are connected
in series, these limit values can be assumed for the entire switch chain as a
subsystem. As a subsystem, this switch chain achieves PL e. If more than
11 devices are connected in series, the PFHd can be calculated using one of
the methods stated in EN ISO 13849-1:2008, Section 4.5.1.
Ì If the simplified method according to Section 6.3 of EN ISO 13849:2008-12
is used for validation, the Performance Level (PL) might be reduced when
more than 11 devices are connected in series.
Ì It is only allowed to use components that are permissible in accordance with
the table below.
