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.
Represents the on response time of the gun, and is needed to
keep the line start position consistent. The value is dependent
on several variables including glue viscosity, nozzle size, and

Issued 12/06
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

Refer to Trigger.
The glue gun stops when the machine stops, and resumes to
complete the current gluing cycle when the machine restarts.
The duration of high voltage or current spike at the initiation of an
electric gun firing.
Refer to Dot Bead Type.
Refer to Dot Pitch.
Refer to Dot Time.
Refer to Modulated Bead Type.
This feature allows the reduction of adhesive usage by entering
the percentage of glue savings. The pattern control
automatically determines the correct length and spacing of the
sub-beads in the bead pattern. Refer also to Sub-Bead.
A bead that results when the pattern control divides a continuous
bead into smaller spaced beads. Sub-beads are used in the
generation of custom bead types (stitched beads, dot beads, and
modulated beads).
The product edge that causes the trigger to stop sensing the
product as the product passes by the trigger. Refer also to
Leading Edge.
A device that receives an analog current signal from the pattern
control and uses it to regulate air pressure. A transducer is used
only in systems equipped for run-up control. Refer also to
Run-Up Control.
A photosensor that detects products as they travel along the
production line. The pattern control can be equipped with one or
two triggers, depending upon the requirements of the DC
application.
Distance that a photosensor passes from the trigger edge to the
other edge of the product. The photosensor is disabled for the
distance entered for the lockout value, thereby preventing
unwanted triggering caused by any holes or contrasting colors on
the product.
A user-determined setting (T-MEM) that allows the user to either
apply or not apply adhesive to products between the trigger and
the guns when line speed recovers after falling below the
minimum-speed setting. If a minimum speed is set, the pattern
control will stop generating patterns whenever the line speed falls
below this speed.
