System description
"Measurement operation"
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
NF 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 NF and LM material it is
below 0.085 seconds.
"FE Measuring fast/normal"
For time-critical applications the measuring time can be slightly shortened for measuring FE
material. If "fast" is selected and double sheet occurs, the measuring is terminated on reaching the
upper switch limit, and the information "2-sheet" is released. If "normal" is selected, the measuring
will be executed to the end and the measured thickness will be displayed.
"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.
"CLR parameter (Clear Program Parameter)"
Deletes all program parameters. For doing so, the parameter needs to be set to "yes". Executing
the command requires several minutes, since the program memory will completely cleared. All
program parameters will be reset to the default values and existing Teach-In data will be deleted.
Using this function only makes sense if a unit is to be newly used for another machine.
"Password yes/no"
Switches the password request on/off. If the password request is set "on", the system / program
parameters can only be changed after the password has been entered.
"External Alignment"
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 alignment may only be performed under supervision of an operator.
