The short answer
Two signals and one power rule decide how the feeder behaves on your line. The yellow wire carries the material signal: with it connected, the feeder tells the placement machine whether labels are present. The green wire carries the feeding signal: with it connected, the machine decides when a label is fed. If you switch the feeding signal off in the feeder menu, the unit feeds by itself whenever the label table is empty, and the machine needs no wiring change at all.
Power the feeder from a 24 V DC supply rated above 2 A. The 80 mA average and 1 A peak figures on the specification sheet describe what the feeder draws, not what your supply has to deliver.
Why the two power numbers get confused
A label feeder is servo-driven. The motor is idle most of the cycle, so average current stays low; the instantaneous draw at the start of a feed is far higher. A supply sized on the average figure will brown out on every feed, and the symptom looks like a feeding fault rather than a power fault.
The same logic applies to speed. The published feeding speed range is 1 to 100, but when you are not chasing placement speed a setting of 30 to 50 holds the label steadier at the pickup point. Positioning accuracy of ±0.2 mm and angle accuracy of ±0.5° are quoted at the discharge point, and they assume the label is presented squarely.
What to set, and in what order
Each step depends on the one before it.
- Fibre sensor setpoint. Set the amplifier working value roughly 200 above the reading you get with no material in the sensing gap. The lamp lights when material is present. If the working value sits below the sensed value, the feeder reports an empty condition.
- Display mode. Auto is the production mode. Manual stops feeding and is used for loading and re-threading.
- Feeding position. If labels do not reach the pickup point, increase it. If they overhang or curl upward, it is too large.
- Feeding speed. Change it only after the strip is clean, then re-trim the feeding position.
- Feeding delay. The unit is 0.1 s. Add delay when the nozzle is slower than the feed.
- Signal selection. Turn the material signal on if the machine needs a present-or-absent signal. Turn the feeding signal on if the machine drives feeding; the machine then supplies a 0 V signal to the green wire. Leave it off for standalone operation.
Threading the material
The path is fixed: reel on the mounting sleeve, through the winding shaft, past the width guide block, under the press plate, out at the discharge table, with the spent backing collected on the waste take-up sleeve.
Loosen the guide block screw and set it to the label width. Adjust the press plate height with its four set screws to suit the label thickness. Hard-to-peel small labels usually respond to flipping the stripping blade to its shallower angle.
Two details that prevent most threading problems: keep the tape running straight rather than at an angle, and for large or easily released labels you can bypass the spring winding shaft so the label does not peel early.
What the feeder needs from you
One feeder slot on the placement platform, a 24 V DC supply able to deliver more than 2 A, and — if you want the machine to drive the feed — one signal line. Nothing else on the placement machine changes.
