4.5 AUTOMATIC DISPENSING SPEED (APSF)

ALS

380

4.5.1 Electronic transmission ratio

of the RPM transmitter (EGRA)

– Required compensation factor for the RPM trans-

mitter

– For ALS 380 HS, refer to the Service Guide

Setting the compensation factor

➔ Calculate the setting value for EGRA:

A= resolution of the RPM transmitter used in mm/pulse

– Possible settings: 100 ... 650 (factory setting: 600),

corresponds to resolutions from 0.10 ... 0.154 mm/

pulse

➔ Call up the EGRA function in the extended menu.

➔ Input the calculated setting value and exit the EGRA

function.

The setting of the electronic transmission ratio

affects the dispensing speed:

– The smaller the EGRA compensation factor,

the greater the dispensing speed.

– When the EGRA has a low setting value and

a high conveyor belt speed, the allowable

dispensing speed can be exceeded.

– If the dispensing speed is too great, the

warning message W__4 appears.

Test the setting:

➔ Remove the pressure roller unit at the dispensing

edge.

➔ Start the system.

– The labelling speed is too low if the product pulls the

label away from the backing material.

– The labelling speed is too high if the label on the

product has folds in it.
