Glossary
Refer to Modulated Bead Type.
A feature of the pattern control that allows the user to determine
the encoder gearing ratio without any calculations. There are
three different methods of autoscaling: product-length method,
line-jog length method, and line-speed method. There is also an
option of entering the value for the encoder gearing ratio if it is
known.
A setting that automatically places the pattern control in the run
mode when power is applied.
A continuous line of adhesive or, in the case of a custom bead (a
stitched, modulated, or dot bead), a line of adhesive that has
been divided into sub-beads. Refer also to Sub-Bead.
Refer to Duration.
Refer to Delay.
A setting that allows the user to select one of five different bead
types.
A setting that inhibits the pattern output if the product length
measured by the photosensor is shorter than the programmed
pattern for a specific channel. If the short product is in product
queue and has not been initiated, it will be removed from the
queue. When pattern clipping is detected a warning is displayed
in the Warnings screen and the warning relay is activated.
When gluing starts or stops at a user specified line speed.
Refer to Minimum Operational Line Speed.
The distance from the leading edge of the product to the
beginning of the bead. Refer also to Leading Edge.
This feature produces patterns of constant-weight
(constant-volume) dots of adhesive spaced apart by a
user-determined distance. Specifying the gun-on time can
control the dot weight. Specifying the dot-interval distance can
control the distance between dots. A constant dot weight and
interval can be produced over the entire range of line speed
without using external run-up equipment.
The repeat distance between the center of one spot and the
center of the next spot.
Controls the gun opening time, which directs the size of the glue
spot.

The distance from the start of the bead to the end of the bead.
The distance from the start of the bead to the end of the bead.
The edge parameter sets the photosensor to sense either the
leading edge or the trailing edge of the product as a trigger.
A device that tracks line position. Using the pulse count from an
encoder, the pattern control can generate highly accurate pattern
sets as line speed varies.
The ratio of encoder shaft rotation to line travel. Encoder shaft
rotation is measured in pulses per revolution and line travel is
measured in millimeters or inches. The encoder gearing ratio is
expressed in pulses per millimeter or inch.
Notification that a serious defect or problem has occurred in the
pattern control system. When a fault occurs, and if the system
is running, the pattern control will stop generating patterns.
Faults need to be cleared manually, or else the problem causing
the fault will not be fixed.
Refer to Purge.
An area at either end of the product where adhesive is not
applied when generating random-length beads. The size of the
margin a can be independently set t both the leading and trailing
edges of the product. Refer also to Random-Length Bead Type.
Refer to Minimum Operational Line Speed.
Gun-to-Trigger Offset. It is the distance from the center line of
the gun nozzle to the centerline of the trigger lens.
The device that opens and closes the gun. A gun actuator can
be a pneumatic solenoid valve or an electric gun driver,
depending upon the type of guns you use in your production
facility.
The ability of the pattern control to produce accurate patterns by
compensating for the delay, large or small, in gun-response time.
Refer to On Compensation.
Refer to Off Compensation.
A button on the main control board that allows you to test-fire the
gun connected to any of the four pattern-control outputs. Using
this button and associated DIP switches, you can activate one
output or any combination of the four outputs.
The dispensing device that applies adhesive to the products.
Sometimes called a head or an applicator, a gun can have a
single dispensing module or it can have multiple modules. Refer
also to Gun Actuator.
