ALS 230

Start delay ______________________________________________________STAD

Function: Delay time for the dispensing by means of an applicator after the product has passed the product sensor. This value influences the position of the label on the product.

Only available if applicator is used. Range: 1 to 9999 ms

Dispensing speed ________________________________________________VELO

Function: The labelling speed may be adjusted with the parameter VELO. Values between 0.2 and 30.0 m/min are possible. The speed has to be adjusted so that it matches the product speed.

When an applicator is fitted to the machine, this parameter defines how fast the label will be dispensed on to the applicator.

EGRA value check ________________________________________________ STST

Use this function to adjust the EGRA value. If the drive-roller speed is higher than that of the conveyor then increase the EGRA value, if it is lower decrease the EGRA value so that the conveyor speed and drive-roller speed match.

Slew speed _____________________________________________________ SLEW

Function: For some situations the labeller can run with a different, higher speed. This occurs during compensation of a missing label on the web, positioning the label at the dispensing edge during initialisation or after pressing the feed button if the APSF-mode is selected. The resulting speed depends on the selection (FAST or SLOW) and the APSF-mode.

SLEW setting	FAST	SLOW
APSF off	Max speed	VELO
APSF on	Max speed	12 m/min

Electronic gear ratio adjustment ___________________________________ EGRA

The parameter EGRA appears in the extended menu only after the APSF function has been switched on.

The range of the EGRA parameter is 100 to 500, representing from 1 to 5 encoder pulses per millimetre of conveyor movement. The full EGRA range can be used up to 30 m/min conveyor speed.

With an applicator there is no realistic limit to the conveyor speed and at very high-speeds an EGRA value at the lower end of the range should be used.

Dwell time _______________________________________________________ APT1

Function: Only used when an EP- applicator is necessary. It defines for how long the pneumatic cylinder is switched on.

Available only with applicator. Range: 1 ... 7500 ms
