Dispense speed __________________________________________________VELO
The speed value VELO displays the dispensing speed in 0.1 m/min. The product conveyor
speed has to be constant to assure accurate labelling. A change of the product speed causes a
different position of the label on the product. In case of inaccurate labelling, it should be
verified, if the speed of 720 and your product match together. This is done automatically if the
optional automatic speed follower (APSF) is installed.
If the 720 is equipped with an applicator, two parameters in the standard menu can be
changed. The delay time which specifies the moment when the applicator must put the label
onto the product and the blow time - how long the applying of the label should take.
Start delay ______________________________________________________STAD
By the aid of the parameter STAD the period of time between the recognition by the product
sensor and the dispensing of the label onto the product is determined. The time units are ms,
the time is adjusted by the keys FUNCTION.
Blow on time ___________________________________________________ BLOW
The labelling time BLOW indicates, for how long the applicator should apply the label onto the
product. This time is displayed in ms also. BLOW is equivalent to APT2 which is found in the
extended menu.
Product menu____________________________________________________ PD0n
This menu can be used for storing data for different labels and products. 9 different sets of
product data can be programmed.
If you want to switch to another product, select the respective product number by pressing
NEXT and PRIOR, then press ENTER. Now the new product data are activated.
To change the labelling parameters you can call the extended menu. After leaving this menu
your product data will be automatically updated.
720 carries out the labelling of your products completely automatically.
Check now and then:
y
if there is still enough labelling material on the unwind roll
y
if an error has been displayed and 720 no longer effects labelling
y
if the label is placed correctly onto the product. If this is not the case, correct the respective
parameter in the standard menu.
Control is even more simple if you use an OD-control, which measures the diameter of the
material roll and indicates a warning message W__5 as the label roll diameter gets too small,
i.e. there are only a few labels left on the label roll. To the warning output you may connect an
alarm indicator, an optical or acoustic signal can be triggered.
