5.4.3 Setting the Tamp Dwell with Auto-Retract ON
When configuring a PA/4000 system using auto-retract, set the tamp dwell
value as low as you can with no missed products. Note the air flow control
and psi setting instructions in Section 5.4.1. The auto-retract sensor cannot
detect an object farther away than ¼-inch.
To find the correct tamp dwell setting (assuming normal operating conditions):
• Determine the maximum distance the tamp pad will extend to the
product.
• Increase the tamp dwell setting until the tamp pad extends to the
maximum distance and reliably applies labels to all products (with
no missed products).
NOTE: Following this procedure will minimize the possibility of
damage to the PA/4000 or the product if the auto-retract does not
detect the product.
5.4.4 Setting the Product Delay with the Hand-Held Terminal
The product (input) delay value controls the amount of time after the
photosensor senses a product that the tamp pad delays before it extends to
apply a label to that product. The possible product delay settings are from 0
to 999. A product delay value of 0 will cause the tamp pad to extend as
soon as the photocell sees a product. Setting the product delay too low will
cause the tamp pad to extend before the product arrives, which could cause
the product to accidentally strike and damage the air cylinder/tamp pad
assembly. Typical product delay settings range anywhere from 300-700 .
As products pass in front of the photosensor, the tamp pad will extend and
apply a label to the product. The product delay value will control exactly
where on the product the label is applied. The product delay time should
be set so that the tamp pad extends when the area of the product where the
label should be arrives at the tamp assembly. The following table gives
delay values and their corresponding times (in milliseconds).
