4.2.2 Monitoring functions
While in dispensing mode, an electronic controller
monitors the following functions:
Material end / Roll diameter
(OD = outer diameter)
To enable a quick renewal of the material roll, the
machine can alarm the operator before the end of the
material roll is reached. This provides the OD-control,
which is available in two versions:
– Internal OD-control
The machine control elaborates the signals coming
from two sensors, which are integrated into the
material unwinder.
– External OD-control (accessory)
A light barrier attached to the material unwinder is
triggered, if the roll OD falls below a certain value.
Depending on the configuration and setting of the
machine, different messages appear in case of material
end or the roll diameter falling below the critical value:
[59] Messages for monitoring label stock.
1) If no rotation of the unwinder was registered during 600mm of material
feeding.
2) If MACHINE SETUP > Materialend err = „Mat.diam < x mm“
3) If MACHINE SETUP > Ext. OD sensor = „Warning“
4) If MACHINE SETUP > Ext. OD sensor = „Error“
If a warning occurs:
– Labelling operation is continued.
 Press the button, to delete the warning.
 Prepare for inserting a new material roll.
