Section 13—The Learn Function MCP-25/MS
Valco Cincinnati 13-6
To learn the glue-pattern position, follow these steps:
1. At the “Learn data” screen (Figure 13-17) press
F4 (Pattern). The screen in Figure 13-18
displays.
2. Start the machine and gluing.
3. Press F2 (Yes). The measuring cycle starts and
the “Measuring glue-pattern values...please
wait” message displays (Figure 13-19).
Note!
If the machine speed is increased, the
glue line will move back, which will
cause faults to occur. If you change the
pressure, the glue-volume learn function
must be repeated!
Note! The glue-pattern-edit screen values will
not match the actual inspected values. If
the values in the glue-pattern-edit screen
are changed, the learned values will be
overwritten.

Learning Glue-Pattern Positions
If all the data (ratio comp and/or valve comp) in the setup screen is correct, it should not be necessary to teach the
glue-pattern position. However, if these settings are incorrect when the machine speed is increased, the glue line
will move back, which will cause faults to occur. It is then necessary to adjust the glue-pattern position by using the
learn function.
It can also happen that, at a certain speed, the glue position does not match up with the values on the glue-pattern-
edit screen. Then, the measured length /position won’t be right and the product will be considered a fault.
If the situation cannot be corrected by adjusting the ratio compensation and valve compensations, the glue-pattern
learn function can be used to “capture” the glue pattern which is correct. After the pattern has been captured, all
boxes will be compared with the position of the “learned” box.
