Single output with advanced fault
detection*
Connection examples for semiconductor outputs
*Two loads may be connected to each safety output with advanced fault detection, even on
applications in accordance with EN IEC 62061, SIL CL 3. Prerequisite: Feedback loop is
connected, shorts across contacts and external power sources are excluded (e.g. through
separate multicore cables). Please note that, in the event of an error in the feedback loop,
the safety system switches to a safe condition and shuts down
all
the outputs.

Using the chip card
CAUTION!
The chip card contact is only guaranteed if the contact surface is clean and
undamaged. For this reason please protect the chip card's contact surface
from
– Contamination
– Contact
– Mechanical impact, such as scratches.
CAUTION!
Switch off the product before inserting or exchanging the chip card.
