Operation
Operating Mode Window
The operating mode Window can be exclusively selected via the parameter assign-
ment software (optional).
SP1: > 1 cm
SP2: > (SP1 + 1 cm)
In contrast to
operating mode 2 ranges,
here the detection
fi
eld that is sensor-
proximal will not be visible. The detection
fi
eld that is sensor-distant still remains.
It extends from switch point
SP1 to switch point SP2. If an object penetrates the
detection
fi
eld far that is sensor-distant, the outputs (preset as normally open con-
tacts) “OUT
X.1” and “OUT
X.2” will be closed. If the object enters into the sensor-
proximal detection
fi
eld, the outputs “OUT X.1” and “OUT X.2” will be opened.
If the object laterally penetrates the sensor-proximal detection
fi
eld, the outputs
“OUT X.1” and “OUT X.2” will remain open.
Measuring – the USi as a Sensor (analog)
The measuring function is only available for USi with analog output. The 2 possible
operating modes are:
Operating Mode 1 Range
Operating mode 1 Range is the preset standard operating mode.
SP1: 1 cm
SP2: 200 cm
Since switch point SP1 complies with the minimum switching distance of only 1 cm,
detection is effectively from the active surface to the switch point SP2. If an object
penetrates the detection
fi
eld, the outputs (preset as normally open contacts) “OUT
X.2” are closed. The distance from the detected object is converted to an analog
value and made available at the analog output “OUT1.1”:
OUT 1.1

The characteristic curve can also be inverted via the parameter assignment soft-
ware (optional).
Information: Upper limit in the blind zone.
The USi has a blind zone of 10 cm
as a sensor. However, the switch point SP1 is preset to 1 cm, so that the full co-
verage range is simultaneously available to the USi as a scanner. Therefore, the
analog value for 10 cm
is indicated on the analog output “OUT 1.1” for the
range
up to 10 cm.
