is connected. The analog output OUT°1.1 can also be assigned an inverted output
signal via the parameter assignment software (optional). (
cf. Output, OUT)
Output digital
Semi-conductor of type PNP. Each output can be an NO contact, an NC contact or
Off. The digital output is preset as NO contact in delivery condition. A changeover
is implemented, e.g., by de
fi
ning output 1.1 as a normally open contact and output
1.2 as a normally closed contact. The digital outputs are de
fi
ned via the parameter
assignment software (optional) (cf. Output, OUT, PNP)
Parameter assignment
software
Optional software, with which all
USi
parameters can be changed via a Windows
®
interface and transmitted via USB interface to the USi. The parameter assignment
software allocates the three modes
Standard
,
Expert mode
and
Diagnosis
.
PNP
Transistor
output
Type PNP.
Proximity switch
Position switch, which is activated without mechanical contact with the moving
object. [IEC
60947-5-2, 2.1.1] (cf.
Ultrasonic proximity switch
)
Real switching distance
Switching distance
of an individual
proximity switch
, which is measured at speci
fi
c
temperature, voltage and installation conditions. [IEC
60947-5-2, 2.3.1.5]
Reference axis
Axis, which runs perpendicularly to the
active surface
and through its centre.
[IEC
60947-5-2, 2.2.2.1] (cf.
Opening angle
)
Reference object
Speci
fi
ed part, which is used for comparative measurements of the
switch points
and the
detection fields
. Synonymous with
measurement object
.
Re
fl
ex barrier
Extended function of an
ultrasonic proximity switch
. The
USi
monitors the area
between
switch point SP1
and a taught-in re
fl
ector. Each change results in signal
change at the
output
. (cf.
Sonic barrier
)
Re
fl
ex switch
Basic function of an
ultrasonic proximity switch
.
Objects
in the
detection
fi
eld
will
be detected, meaning sensed using the
sonic lobe
.
Repeatability
Make a change to the
real switching point
under predetermined conditions.
[IEC
60947-5-2, 2.3.4] Indicates the accuracy of measurement results, which have
passed through the same
switch point
with predetermined conditions. Synonymous
with reproducibility.
RESET
Function with which the
USi
is set back to the
delivery condition.
Subsequently,
the
USi
will start with the
factory settings
.
Resolution
Smallest unit of length, which can be differentiated by a
proximity switch
. Resolu-
tion of the USi: 1
mm. (cf.
Measurement
resolution
)
Secondary object
Object
in the
detection field
, which is not an
object
to be detected. Examples:
machine parts, shelves, columns, etc. In order to prevent malfunctions, the
USi
will
be subjected to a
Teach
In
of the environment incl. all secondary objects.
