4.5.2 Electronic transmission ratio
of the RPM transmitter (EGRA)
– Required compensation factor, in the event that an
RPM transmitter with a resolution other than
0.157 mm/pulse is used.
Setting the compensation factor
£ Calculate the setting value for EGRA:
A = resolution of the RPM transmitter used in mm/pulse
– Possible settings:100 ... 1,000, corresponds to res-
olutions from 0.10 ... 1 mm/pulse
£ In the extended menu, call the EGRA function.
£ 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 (optional) at the dis-
pensing 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.
