System description
From this some simple rules derive, which enable a large degree of process security when abided
by:
•
Always care for good contact of the sensor with the material!
•
Use separate programs to measure different sheet thickness (and alloy)!
•
Adjust the switching thresholds as tight as possible!
Furthermore it is necessary that the control checks all status signals of the UDK20, also the
0-sheet signal. While measuring, only the 1-sheet signal may occur. If 0-sheet or 2-sheet occurs,
the measured sheet may not be transported on. In such cases, the sheet will usually be deposited,
re-picked and measured again.
•
The control needs to evaluate all status signals !
Checking-up through the 0-sheet signal is to assure that a sheet really is in front of the sensor
during measuring. If 0-sheet occurs while measuring, the measurement is not correct. For example,
a defective sensor holder might prevent the sensor from contacting the sheet. Monitoring the sheet
thickness would then only be performed apparently.
In case of double sheet fatal consequences could then result.
3.3
Control unit
The UDK20 is based on the product platform R1000.
Major features of the control unit:
•
Programmable for 255 different sheet thicknesses and materials
•
Fieldbus interface for the control, operation and data exchange with the PLC
•
Calibration by a Teach-In procedure
•
Digital display of sheet thickness and operating parameters
•
Monitoring of over gauge and under gauge limits
•
Monitoring of operating voltage and sensor gap
•
Optocoupler for direct I/O control via the PLC for fast measurement operations
•
Software firmware update
•
Data backup via fieldbus interface or serial interface

Parameters of the control unit
The UDK20 provides for extensive configuration. So, different customer requirements can be
served. Configuration is performed by setting system parameters and program parameters. System
parameters are set only once on commissioning, and will then remain unchanged. Program
parameters contain items which are material and job depending, and enable individual adaptation
to the measuring task.
