In the measuring mode, the measured value is shown on the display. The comparison of the measured value
with the adjusted thresholds is done automatically by the control unit.The result is transmitted via the
interface to the PLC and also to the front panel LED's.
During the normal measurement process no further actions on the control units are necessary with the
following few exceptions. The following situations require action directly at the control unit:
•
Clear fault and error messages (see to chapter 9. "Fault messages, causes and remedies")
•
Teaching of new types of metal and sheet metal thicknesses
(see section 7.7 "Configuration of program parameters")
•
Clearing a 2-sheet condition (in preparation)
The following notes for measuring operations should be observed:
Note: If the measured value fluctuates and deviates substantially from nominal
value during normal operation then an air gap between sensor and sheet surface is
the most likely cause. A renewed Teach-In cannot solve this problem.
Note: With non-ferrous materials (e.g. aluminum) changes in the electrical conductivity
can occur requiring a teach-in.
Note: Do not adjust the upper threshold above 120 %.
