System description
"Number of sensors"
Defines the number of connected sensors. Those sensors are then available for measuring.
At a 2-channel unit (UDK20-2PW...) max. 2 sensors can be connected, at a 1-channel system with
sensor-switch-box max. 4 sensors can be connected.
"FE-T-limit"
On teaching-in of FE material the deviation of the measured thickness from the nominal thickness
will be monitored. Certain ferromagnetic materials show larger deviations as usual. In these cases
the 33% / 142% setting makes sense. Default setting is 66% / 125%. Both values represent the
permitted relative range of measured to nominal thickness. If the measuring value is not within this
range, the Teach-In cannot be performed and will be aborted with an error message.
"Measuring mode"
Sets how the measuring is to be triggered. The following modes are available:
• Demo
The demo mode is only intended for test and demonstration purposes. In this mode
measuring is performed until the demo mode is switched off again. For doing so, another
mode must be selected. The repetition time of the measuring is 1 second for FE material, for
NE and LM material it is below 0.085 seconds.
• Ext. Single (default setting)
Here a single measuring is performed. For doing so, the signal "Measuring start" must be
externally fed. Another measuring requires a new flank of the "Measuring start" signal.
• Ext. Permanently
Here the measuring is maintained as long as the signal "Measuring start" is fed. The
repetition time of the measuring is 0.5 seconds for FE material, for NE and LM material it is
below 0.085 seconds.
"Hold 2-sheet"
Currently only "no" is possible.
"External Measurement start"
The signal "Measurement start" can be linked via 3 opto coupler inputs (Measuring start input
1,2,3). Possible configurations:
• IN0 (default setting)
• IN0 and IN1
• IN0 and IN1 and IN2
"Output 0-1-2"
Sets the logics voltage for outputs 0-,1-,2-sheet and "Warning". Default setting is 0 VDC.
"External Adjust"
Sets whether an external Teach-In / zero adjust is to be possible. If "yes" is set, the PLC can trigger
the procedure via the inputs "Teach-In 0-, 1-sheet". Default setting is "no".
• The external adjust may only be performed under supervision of an operator.
