Note The uncorrected thickness (thickness taken from the curve) is issued via
the process channel. Should the thickness deviate more then 10 percent
(exceptions 20 percent) from the nominal thickness then the cause for
this deviation must be investigated. This could be: wrong sheet, wrong
thickness, bowed sheet, air gap between sensor and sheet.
Note The measured timing periods were determined with 12 Mbit- Profibus.
These timing periods can vary with different transmission rates and bus
systems. The cycle time of the PLC has not been taken into account.
Note According to the setting in the configuration menu, item 12
"Sensor selection" the Teach-In causes following:
- external:
the selected sensor in "selection A/B" is teached.
- Program:
the selected sensors in the active program are teached.
