1.3 Functional principle
The Safet evaluation unit monitors connected sensors that are equipped
with a NO contact and NC contact. The switching sequence of the contacts
does not matter.
The Safet evaluation unit switches a safet output in accordance with the
operating statuses of the connected sensors and the connected external
contactors.
In the following situations, the Safet evaluation unit switches off the safet
output:
• The sensors are correctl actuated.
• The feedback contacts of the external contactors are closed.
In the following situations, the safet evaluation unit switches off the safet
output:
• An NO contact of a connected sensor is open.
• An NC contact of a connected sensor is closed.
• A fault is pending (the safet evaluation unit or a connected sensor is de-
fective).
1.3.1 Intended use
The safet evaluation unit is part of the overall s stem or machine and is for
the purpose of assuming safet -related functions. In order to do so, the s s-
tem monitors signals from magnetic safet sensors. This means that the out-
put is opened or closed depending on the status of the safet sensors.
The product must be used onl in accordance with the descriptions below
for protection against dangers.

1. User information EN
12.7.23 V2.1 5 / 24
Observe all applicable health and safet conditions, laws and directives of
the respective machine. There are no known residual risks, if all of the infor-
mation contained in this operating manual is complied with.
Ever non-intended use and all activities performed that are not described
in this manual represent a prohibited, incorrect use outside the legal limits
of liabilit of the manufacturer.
1.3.2 Foreseeable misuse
The following operating conditions are classified as misuse:
• Use in potentiall explosive areas,
• use in aeronautical and aerospace applications, nuclear and militar ap-
plications,
• operation without fuse,
• non-compliance with the technical data.
Operation contrar to the intended use will void the warrant .
WARNUNG!
