2-channel selection shown by way of example
of a guard monitoring with two position
switches, of which at least one is positively
opening; with external reset button J.
Power level: 2-channel selection control,
suitable for contact amplification or contact
multiplication by means of contactor or relay
with positive driven contacts.
Wire breaks, earth leakages and cross-shorts
in the monitoring circuits are detected.

Safety function
The safety function is defined as follows: The
enabling outputs 13-14/23-24 is open, when
the inputs S11-S12 and/or S21-S22 opens.
The safety related current path with the output
contacts 13-14 fulfil in consideration with a
B -value view the following requirements
10d
(refer also to "Information within the meaning
of DIN EN ISO 13 849-1"):
•
category 4 – PL e
acc. DIN EN ISO 13 849-1:2007
• is equivalent to SIL 3
acc. DIN EN 61 508-2:2002
• is equivalent to SILCL3
acc. DIN EN 62 061:2005
(is equivalent to control category 4
acc. DIN EN 954-1:1997)
For designation of the performance level (PL)
acc. DIN EN ISO 13 849-1:2007 of the whole
safety function (e.g. sensor, logic, actor) a view
to all relevant components is necessary.
