6.2 Additional sensor installation guidance
The surface temperature of the sensor depends on the operating mode, the parameter selection and the
thermal exposure of the sensor to the environment.
Make sure that the sensor complies with the following requirement:
The surface temperature for easily accessible surfaces may be max. 25 °C higher than the ambient
temperature (to IEC 61010-2-201).
The following diagrams contain typical warning limits as a reference for the installer.
The diagrams are valid for the following operating modes:
●
Low [1 exposure]
●
Moderate [2 exposures]
●
High [3 exposures]
In the event of moderate and high exposures the typical warning limits must be determined via the
sum of the exposure times. The exposure times are indicated in the software ifm Vision Assistant.
Follow one of the instructions if the warning limits are exceeded:
►
Reduce surface temperature
.
►
Mount the sensor in a location or housing that provides protection from the heat source but maintains
air circulation around the sensor.
> An increase in the surface temperature of the sensor should be prevented.
The parameter "Max. background distance" is set in the ifm Vision Assistant. In the diagrams the
warning limits of the parameter are shown with dashed and continuous lines.
If the sensor is in one of the dotted areas, the surface temperature must be reduced
. If
the warning limit is exceeded despite a heat-dissipating installation, it is possible to additionally
mount the contact protection.
If you stay below the typical warning limits in case of normal installation, no measures need to be taken.
