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.
