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.

Refer to Spike TIme.
Refer to Pitch.
This feature activates a warning when a photosensor is active
longer than the user defined product length. Select Jam Detect
on, then press the product length text box, enter a value greater
than the product length being glued.
Liquid Crystal Display.
Refer to GTO.
The edge or face of the product that the trigger senses first on
the production line. Leading edge is also used as the starting
point for the delay measurement. Refer also to Trailing Edge
and Delay.
Light Emitting Diode.
Refer to Duration.
Refer to Trigger Mask.
Refer to Gap.
This length setting is used when the boxes contain holes or
cutouts which the photosensors are programmed ignore.
The speed below which the glue application ceases.
This feature provides a nearly constant bead volume below a set
line speed. When the production line is set to a user-selected
speed, the control starts dividing each bead into shorter
sub-beads to prevent bead volume from increasing. The total
gun-on time to produce each divided bead remains the same as
the total gun-on time to produce the original solid bead, therefore
the bead volume remains the same.
Refer to Pitch.
Machine Speed Detector. Refer to Encoder.
Refer to Product Queuing.
Represents the off response time of the gun, and is needed to
keep the line end position consistent. The value is dependent on
several variables including glue viscosity, nozzle size, and height
of the gun above the product surface.

keep the line start position consistent. The value is dependent

A feature of the pattern control that handles pallet-stabilization
applications. Use this feature to set the number of consecutive
products that receive adhesive and the number of consecutive
products that are skipped before pattern generation starts again.
All of the beads produced by a single gun.
Refer to Photosensor.
A device that detects products as they travel along the
production line.
The distance from the start of one bead to the start of the next
bead or, in the case of custom bead types (stitched beads, dot
beads, or modulated beads), the distance from the start of one
sub-bead to the start of the next sub-bead
.
The ability of the pattern control to simultaneously track the
position of several products as they move from the trigger to the
guns. This feature allows the user to install the sensor farther
from the guns, space products closer together, and run the
production line faster.
Refer to Recipe.
Test value for pressure.
Preset run-up value that automatically engages when purging.
The process of removing trapped air or material from the
adhesive gun or nozzle, or of relieving system pressure by
turning the gun (or guns) on.
A custom bead type that the pattern control can generate. The
random-length feature allows the user to apply a continuous
bead of adhesive to products of different length. If desired, set a
gap at the leading and trailing edges of the product where
adhesive will not be applied.
All of the pattern settings and associated parameters for applying
adhesive during a single production run. A program includes the
measurements that define a pattern set and may include
volume-control settings (if the run-up feature is purchased and
installed), optional settings such as the low-line-speed warning,
and custom bead settings such as stitching or modulation.
A feature that allows the user to test-fire the gun connected to
any of the four pattern-control outputs. Using this button and
associated DIP switches, one output or any combination of the
four outputs can be activated.
A pressure variation feature that varies pump output as line
speed changes to provide a consistent bead volume.
The glue gun stops when the machine stops, but will not start
again until the photocell detects a trigger to begin a new gluing
cycle
