4.1 ACTIVATION AND SHUT-DOWN

ALS

350

450

Unwind unit

– A loop forms in the loop space as a buffer between

the unwind unit and label dispensing,

ALS 350: [44 arrow], ALS 450: [45 arrow].

– A photoelectric sensor in the loop space monitors

the loop.

– If the loop becomes too large, the control system au-

tomatically slows the unwinding speed. The dis-

pensing speed does not change.

– ALS 450: The dancer arm swings approximately into

the centre position [45B].

Rewind unit

– The multiple deflections with the spring-loaded

dancer arm act as a buffer between the label output

and the rewind unit. During operation, the dancer

arm swings between the horizontal and its upper

end limit,

ALS 350: [44A], ALS 450: [45A].

– If necessary, the control system automatically slows

the rewinding speed. The dispensing speed is not

affected by this.

4.1.3 Stop/end the label dispensing

£ Press the ENTER key.

– The unwind unit, dispenser drive, and rewinding unit

shut down.

– „OFF“ appears on the operator panel [46].

– Start signals from the product sensor are ignored.
