4 OPERATION 4.4 SETTINGS IN THE EXTENDED MENU 4.4.12 Number of unlabelled products (MLAB) If products do not get labelled, the operator receives the warning message W_0 at the operator panel. If too many products in a row do not get labelled, the machine stops. The error message E_11 appears at the operator panel. Using the MLAB function, you can determine how many products in a row are allowed to be unlabelled before the machine stops. Example [84]: MLAB is set to value 2.

4 OPERATION 4.4 SETTINGS IN THE EXTENDED MENU 4.4.14 Advance print start ALS 350 450 (PDT) When using a printer (optional): The printing process can be started even in the final phase of the label feed. In so doing, the printer stamp is already moving toward the label ribbon, even before the label has come to a standstill - this shortens the printing process. Using the PDT function, you can determine when (after how many motor strokes before label stop) the printing process will be started.

4 OPERATION 4.5 AUTOMATIC DISPENSING SPEED (APSF) 4.5 ALS 350 450 AUTOMATIC DISPENSING SPEED (APSF) 4.5.1 Principle of operation A [86] A RPM transmitter (speed sensor) on the conveyor line Conveyor belt and label dispenser are operating in perfect synchronisation. As a prerequisite for this, the RPM transmitter must be correctly adjusted. Depending on the operating conditions, the relationship between the dispensing speed and the conveyor belt speed must be finely adjusted (EGRA function).
