Intended use
Intended use
The ultrasonic industrial sensor USi is designed for industrial use in the medium air.
It is comprised of the Evaluation Unit and up to 2 sensors (ultrasonic transducers).
It can be used to achieve the following functions:

ex barriers and Analog distance detection are possible us-
ing stand-alone (i.e. without parameter assignment software) master or slave units.
2 sensors (ultrasonic transducers) are required for the sonic barriers; several syn-
chronised USi (1 several slaves) are required to be multisensory.
Limits
r
Safety-related tasks are not possible with the product.
r
The use of the product in potentially explosive environments (ATEX) is not
possible. The product is not authorised for use in these areas.
r
Objects with a highly sound-absorbing surface such as open-pore foam, cordu-
roy, etc., cannot be reliably detected.
r
Objects with an extreme sound-dividing shape such as cone tip, or similar can-
not be reliably detected.
r
Strong
fl
uctuations in temperature within very short periods of time cannot
counter balance the integrated temperature compensation.
Safety instructions
Ä
Do not open sensors (ultrasonic transducer)
Never open, manipulate or alter the sensors.
Ä
Do not squeeze the sensors
Avoid applying increased mechanical loads to the enclosure and the active
surface of the sensor (ultrasonic transducer).
Ä
Check supply voltage
Check supply voltage. It must correspond with the connecting voltage U
S
speci-
fi
ed on the type plate.
Ä
Observe protection class
The Evaluation Unit only has protection class IP65 with carefully screwed on
screw plug and carefully
fi
tted lid.
Ä
Protect from sunlight
In the case of surface installation, ensure that the Evaluation Unit is protected
from direct sunlight.
