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.

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
.

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.

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.
