Fine tuning of the dwell time (APT4)
When using an applicator in combination with the auto-
matic speed adjustment (APSF):
– Optimise the accuracy of the label position on the
product by fine tuning the dwell time for the applica-
tor.
Standard values:
– Blowing applicators: approx. 25 ms
– EP applicators: 60 ms ... 100 ms, depending on the
length of the stroke
Prerequisite:
– External RPM transmitter is calibrated (EGRA func-
tion)
Determining and setting the exact value [88]:
£ Call up the APT4 function in the extended menu.
£ Set the setting value for APT4 to 1.
£ Allow the conveyor belt (with products) to run slowly.
– Speed v
N
= 10 m/min
£ Document the position of the label on the product:
Value: POS
N
in mm
£ Increase speed of the conveyor belt to approx.
25 m/min (value v

).
£ Document the position of the label on the product:
Value: POS
H
in mm
£ Calculating the setting value for APT4:
£ Input the calculated setting value.
£ Confirm the value using the ENTER key and exit the
function.
Test the setting:
£ Test the labelling accuracy at different conveyor belt
speeds.
£ If necessary, correct the setting value for APT4:
– The greater the value for APT4, the farther forward
the label is applied.
– The smaller the value for APT4, the farther to the
rear the label is applied.
