Safety information
2.1
Intended use
The DT35S safety-related distance sensor (also referred to as “device’ in the further
course) is an optoelectronic sensor intended for non-contact distance measurement of
objects.
The device is intended for use in protective devices, in mobile applications on electri‐
cally operated autonomous platforms, and in stationary applications for access protec‐
tion and presence monitoring for objects.
The safety-related distance sensor must only be used within the limits of the prescribed
and specified technical data (
see "Safety-related parameters", page 59
) and operating
conditions at all times.
Use inconsistent with the intended use, operation beyond the technical limits, improper
modification of, or manipulation of the device, will invalidate any warranty from SICK;
in addition, any responsibility and liability of SICK AG for damage and consequential
damage caused by this is excluded.
2.1.1
Reasonably foreseeable misuse
WARNING
Risk of ineffectiveness of the protective device!
The objects to be protected may not be recognized in case of non-observance.
The device works as an indirect protective measure and cannot provide protection from
pieces thrown from the application nor from emitted radiation. Objects within the blind
zone and outside of the safety-related detection zone as well as transparent objects will
not be detected.
•
You must only use the device as an indirect protective measure.
The device is
not
suitable for the following applications (this list is not exhaustive):
•
Outdoors
•
Underwater
•
In explosion-hazardous areas
•
Use beyond the technical specifications
As a safety-related sensor, the device with performance level b (PL b), Category
B (according to EN ISO 13849-1:2015) and performance class B (according to
IEC TS 62998-1:2019) is only intended to perform part of the safety function (partial
safety function). In its safety function, it provides sensor information to a downstream
logic unit for further processing.
The safety function arises only in context with the target application, for example
machine tools, a mobile platform, or a service robot.
Requirements and features of the application may differ from the features and char‐
acteristic values of the product and must be evaluated within the scope of project
planning.
2.2
Improper use
Any use outside of the stated areas, in particular use outside of the technical specifica‐
tions and the requirements for intended use, will be deemed to be incorrect use.
•
The device must not be used in explosion-hazardous areas, in corrosive environ‐
ments or under extreme environmental conditions.
