SICK DT35S - Alarm Function - Clamp; Non-Safety-Related Functions; Normalized Measurement Function (Decreasing Behavior)

of the “Clamp” behavior when no measurement provides a result within the measuring
range. The “Hold” setting is not recommended for safety-related use as there is no
immediate detection of an error condition.
Status IO-Link process data
Operational status Measured values in the valid range
Safety-related state No measured values (measured value 0) are
transmitted
3.7.8 Alarm function - clamp
In the case of the alarm function with the “Clamp” setting, a defined state is assumed
in the event of a measurement without a result, thus signaling that no target is currently
available or that no measurement is possible for other reasons. This function can
be used with the IO-Link interface as well as the analog current output, whereby the
following states are assumed in the event of an error.
Interfaces Safety-related state
IO-Link Measured value 0
Analog current output Measured value ≤ 3.5mA

Measurement successful or measured value determined: Output measured values

No measured value determined: Output substitute value
3.8 Non-safety-related functions
In addition to the safety-related functions, the device also has non-safety-related func‐
tions that can be used for diagnostic purposes and to generate additional application-
specific information.
3.8.1 Normalized measurement function (decreasing behavior)
The analog current output provides a continuous output of current values representing
a measured value within a defined distance range. The scaling can be configured in
the range from 4mA to 20mA. The falling decreasing must only be used for non
safety-related purposes.
