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.
