11.2.8 SM114 Transfer unit does not leave home position
There are sensors that check the positions of this component. If one of these positions is not reached
or left in time a corresponding message will appear. These problems usually have some mechanical
cause which you will easily detect.
11.2.9 SM115 Transfer unit does not reach work position
There are sensors that check the positions of this component. If one of these positions is not reached
or left in time a corresponding message will appear. These problems usually have some mechanical
cause which you will easily detect.
11.2.10 SM116 Transfer unit does not leave work position
There are sensors that check the positions of this component. If one of these positions is not reached
or left in time a corresponding message will appear. These problems usually have some mechanical
cause which you will easily detect.
11.2.11 SM119 Label check Error after label feed
After dispensing a label there must be a label on the vacuum pad, detected by the integrated vacuum
control. In this case the control unit does not detect a vacuum which means that probably there is no
label on the pad. The reason for this may be a web break or a missing label on the web. Carry out a
visual check.
11.2.12 SM120 Label check Error after label transfer
After transferring a label there must not be a label on the pad anymore, detected by the integrated
vacuum control. In this case the control unit still detected a vacuum which means that probably there
is still a label on the vacuum pad. Carry out a visual check to determine the cause. Maybe this is even
a problem with the material to be labeled (the label could not stick to the product).
11.2.13 SM130 Error control prism air pressure low
This message appears if the operating pressure is set too low to control the prism. Increase the
operating pressure for the prism.
11.2.14 SM134 Printer fault
This message appears if there is some malfunction at the printer. Maybe an error of the electrical
connection (e. g. plug is loose, or foil is used up). Carry out a visual check.
11.2.15 SM141 Undefined movement of label web
The label sensor has signalized a level variation although there was no web transport. If the web has
not been moved manually the following may be the cause:
> Label sensor misadjusted
> If in position of rest, the label protrudes too much beyond the beak
> Web brakes have no effect
Remedy:
> Re-adjust label sensor:
– Check switching point of label sensor
