Compensation
- Compensation is a number that functions within a formula to reduce the Label Placement
value based on the encoder velocity. When products move faster on the conveyor, the label dispense must
begin sooner to compensate for the acceleration time of the label to the product. The following explains
how to setup compensation for the different applicators.
Air Blow and Tamp Compensation Setup
When selecting a value for rate compensation, start at 0.017. Apply labels to the product at a slower speed.
Then run the product at production speeds or faster. If the labels are applied in the same place, the
compensation is correct. If the labels move back at higher speeds,
INCREASE THE COMPENSATION .
If the labels move forward, DECREASE THE COMPENSATION. Whenever the rate compensation
value is adjusted, it is advisable to re-run the product at various speeds to make sure that the labels are
applied in the same position.
Merge Compensation Setup
When selecting a value for rate compensation, start at 0.008. Apply labels to the product at a slower speed.
Then run the product at production speeds or faster. If the labels are applied in the same place, the
compensation is correct. If the labels move back at higher speeds,
INCREASE THE RATE
COMPENSATION . If the labels move forward, DECREASE THE RATE COMPENSATION.
Whenever the rate compensation value is adjusted, you should re-run the product at slower and faster
speeds to make sure that the labels are applied in the same position.
Notes: 1) Label Placement units with the Encoder Option on are in inches, not seconds.
2) The Encoder Option will not be accurate with a Normal Tamp Applicator.
3) It’s important to make sure that the Applicator is setup properly so labels are dispensed
consistently.
4) If product speeds are too fast causing the compensated Label Placement to lag behind the
current Label Placement, a warning will be given to raise the label placement value.
5) If the Encoder Option is turned off, all of the Encoder-Based Options will also turn off
automatically. This is shown on the Display when the Help Key is pressed.
