2.5. Service monitor
2.5.1. Valuation of label parameters
In function menu "Parameter of label photocell" you will find the service monitor, by which the
photocells can be checked res. adjusted.
When measuring the labels the values will be displayed in the first line, thereby the following
measured voltages are shown:
A:
absolute minimum (measured on backing-paper)
B:
smallest maximum (measured on label)
C:
upper switching level
D:
lower switching level
E:
highest voltage measured (mostly ~5 V)
The sketch illustrates the voltage wave form of the label photocell while measuring the labels.
The difference between "A" and "B" should be at least 1,5 V.
