Remote Junction Box (contd)
The remote junction box can be connected to a 4-channel voltage modedriver. Inside the remote junction box there are configuration switches(SW3, SW4, SW5, SW6) that select what channels are to be purged from itsremote purge input (for location see Figure 7). All positions of the switchshould be closed to purge the indicated engine’s output.
The remote junction box has the flexibility of assigning any of the fourtrigger inputs to any of the pattern controller’s eight trigger inputs. There isan 8-position switch (SW7, SW8, SW9, SW10) for each of the remotejunction box’s trigger inputs that is used to assign triggers.
The double-stack D-shell connectors (X8, X7, X1) are used to daisy-chaintheir signals to other remote junction boxes. The only exception is whenusing the 2 trigger/6 gun configuration. In which case, the second 9-pinD-shell connector is dedicated to gun signals E and F.

Refer to Gap.
The speed below which the glue application ceases.
This feature provides a nearly constant bead volume below a setline speed. When the production line is set to a user-selectedspeed, the control starts dividing each bead into shortersub-beads to prevent bead volume from increasing. The totalgun-on time to produce each divided bead remains the same asthe total gun-on time to produce the original solid bead, thereforethe bead volume remains the same.
Refer to Pitch.
Machine Speed Detector. Refer to Encoder.
Refer to Product Queuing.

Refer to Photosensor.
A device that detects products as they travel along theproduction line.
The distance from the start of one bead to the start of the nextbead or, in the case of custom bead types (stitched beads, dotbeads, or modulated beads), the distance from the start of onesub-bead to the start of the next sub-bead.
The ability of the pattern control to simultaneously track theposition of several products as they move from the trigger to theguns. This feature allows the user to install the sensor fartherfrom the guns, space products closer together, and run theproduction 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 theadhesive gun or nozzle, or of relieving system pressure byturning the gun (or guns) on.
A custom bead type that the pattern control can generate. Therandom-length feature allows the user to apply a continuousbead of adhesive to products of different length. If desired, set agap at the leading and trailing edges of the product whereadhesive will not be applied.
All of the pattern settings and associated parameters for applyingadhesive during a single production run. A program includes themeasurements that define a pattern set and may includevolume-control settings (if the run-up feature is purchased andinstalled), 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 toany of the four pattern-control outputs. Using this button andassociated DIP switches, one output or any combination of thefour outputs can be activated.
A pressure variation feature that varies pump output as linespeed changes to provide a consistent bead volume.
The glue gun stops when the machine stops, but will not startagain until the photocell detects a trigger to begin a new gluingcycle.
