System Overview
Power Supply
The EPC-15 pattern control requires an external power supply to convert
from AC to DC power. Nordson offers two different power supplies:
S a 2.5 A power supply in an IP54 sealed enclosure
S a 2.5 A power supply in an unsealed enclosure
Both are autoranging units that can accept power from 90 to 135 VAC or
from 175 to 264 VAC and convert it to a regulated 24 VDC.
The power supply must be sized to handle the total load of all guns plus
the load of the EPC-15 pattern control. For information on selecting a
power supply for your system, refer to System Design in Installation.
Gun
The EPC-15 pattern control operates one or more adhesive-dispensing
guns, up to four guns total. Use either pneumatic solenoid valves or
electric gun drivers, depending on the type of guns used.

System Overview
Autoscaling
The EPC-15 pattern control’s autoscaling feature determines the line
speed based on a product’s length. The pattern can then be entered in
terms of distance instead of time. This saves setup time by avoiding a
manual computation of line speed.
Quick Pattern Definition
Measure the length of each bead and the distance from the leading edge
of the product to the start of the bead. Then select the beads by gun and
bead number, and enter the measurements in either time (default option),
millimeters, or inches to define patterns.
The following figure shows a typical bead (bead 2 from gun 1) and the
measurements required to define it.
S bead offset 120 mm (4.7 in.)
S bead length 30 mm (1.2 in.)

Explanation
At least one trigger is required and up to three can be used for
more complex pattern sets.
The EPC-15 provides four individually controlled outputs for
operating either pneumatic solenoid valves or electric gun
drivers. The unit can support gun loads of 1.10 A per output.
However, the total gun load must not exceed what the power
supply (or supplies) can support. Refer to External power supply
below.
The power supply must supply enough power to support the
controller (0.5 A), plus the total gun load, plus the load of the
photoeyes. Provide a power supply or choose from the two
power supplies that Nordson offers:
S
PS-40 (2.5 A)
S
EPS-20 (2.5 A)
NOTE: The EPS-20 power supply must be mounted inside an

The type of trigger to be installed determines the procedure to be
followed. A limit switch can be installed, or any of the following types of
photosensors can be used as a trigger:
S a retroreflective sensor (with standard lens)
S a retroreflective sensor (with polarized lens)
S a diffuse reflective (proximity) sensor
1. Select a location for the trigger as directed by the objectives in the
following table.
Objective
Recommendation or
Requirement
Protect trigger from water and dust
Choose a suitable place for the
IP54 enclosure (which is splash
and dust resistant).
Ensure good product sensing
Make sure the distance between
the trigger lens and the target is
within recommended range:
NOTE: The sensor should be
placed 2 in. from product. This
prevents outside sources from
triggering the sensor (false
triggering).
S
Diffuse reflective (proximity)
type: 51−381 mm (2−15 in.)
S
Retroreflective type (polarized
lens): 51−2130 mm (2−84 in.)
S
Retroreflective type
(non-polarized lens):
51−4500 mm (2−180 in.)
Avoid exceeding the controller
queuing capability
Choose a location that will not
permit more than four products
between the trigger and guns at
any time.
Ensure proper operation of pattern
control
Make sure the time between the
trigger and the first bead of each
gun is greater than 2
milliseconds plus the time for
gun to fire adhesive.
NOTE: For random-length
operation, the trigger must be
farther from the gun than the
longest pattern length (i.e.,
the distance from trigger to
gun is greater than the
distance from the start of the
box to the end of the last
bead).

WARNING: Risk of electrical shock. The base-panel ground
lug must be connected to a reliable earth ground. Failure to do
so can result in personal injury or death.
CAUTION: Do not connect AC lines to the unit or any DC lines
that exceed 30 VDC. The EPC-15 pattern control unit is
designed for 24 VDC inputs, outputs, and contact closures.
Powering the unit with too much voltage applied can blow fuses
and/or damage the unit.
CAUTION: Do not reverse the two wires that supply power to
the unit at positions 1 and 2 of X1. Reversing the voltage to the
unit can blow fuses and/or damage the unit. Position 1 is the
positive input and position 2 is the common input.
NOTE: The maximum wire size that can be used to connect to the
terminal blocks on the main control board is 1.5 mm@ (16 AWG).
2. Clip off or tape back the current-sourcing output (PNP) wire on the
trigger cable.
NOTE: Only current-sinking (NPN) sensor outputs will work with the
EPC-15 pattern control. Nordson provides a trigger conversion
service kit for triggers with only a sourcing output or voltage other
than 24 VDC. Refer to the Parts section.

Stitched Bead Patterns
Stitched bead patterns provide a way to reduce adhesive usage and
increase bond strength. Enter the percentage of glue savings desired
and a stitch interval. The controller automatically determines the stitch
pattern that will provide the desired savings. It does this by dividing each
original solid bead of a pattern into sub-beads with spaces between
them.
For example, if the adhesive savings for a bead pattern is set to 30
percent, the stitched beads will be produced with 70 percent of the
adhesive used to produce the original non-stitched beads. The pattern
control always places a sub-bead at the beginning of the original solid
bead and at every interval thereafter. Sub beads may not line up with the
end of the original bead, but it will never go past it.
Control the amount of adhesive used by entering the gun savings and
gun interval savings explained in the table on page 4-19. If the resulting
pattern does not have sufficient bond strength, a quick adjustment to the
percentage savings can be made. Adjust the percentage to the
maximum possible adhesive savings without loss of bond strength.
Trigger Minimum
Set the minimum allowable distance (generally the product length)
between trigger events for trigger 1 and (if used) triggers 2 and 3. This
feature is used to ignore unwanted triggers from the product.
This feature is not needed unless the product has gaps in it, resulting in
multiple triggers per box.
Speed
Set the speed of the production line. If speed is known, enter it directly.
Otherwise, use the autoscaling procedure.
Autoscaling
Automatically determine the line speed, given a known product length.
Provide to the EPC-15 pattern control the length of the pattern that
passes under trigger 1, and the system will compute the required speed.
Refer to the following figure for an example of using this procedure.
NOTE: If the COMPUTATION or RUNNING error messages are shown,
refer to Troubleshooting for details.

Single Gun (contd)
Observation
Conclusion
Recommended Action
Gun dispersed adhesive and LED
turned on
The gun, gun actuator, and gun
circuitry are working properly
Look for the cause of the problem in
other parts of the system. Refer to
Single Pattern Missing (One Gun
Not Firing) in this section.
Gun failed to dispense adhesive,
but LED turned on
Problem is in gun actuator
(pneumatic solenoid valve or
electric gun driver), in gun circuit
wiring, in melter, or in gun itself
Refer to troubleshooting for these
parts of the system in Single Pattern
Missing (One Gun Not Firing) in this
section.
Gun failed to dispense adhesive
and LED failed to turn on
24 VDC power is not being sent to
gun, gun is drawing too much
power, or short has occurred in gun
circuit
Unwire solenoid valve. Repurge the
gun. If LED comes on, there is a
short. Check terminal connections
with a DC voltmeter. Refer to Test
Voltages in the Troubleshooting
Checks and Tests section.
Checking Trigger Operation
Use this procedure to check for proper trigger operation. The system
may be equipped with one, two, or three triggers (photosensors).
1. Verify that the control is receiving an input signal from the trigger as
follows:
a. Remove the terminal block cover from the EPC-15 pattern control.
b. Locate the LEDs for trigger 1 (DS3), trigger two (DS4), and trigger
three (DS5) between terminal blocks X1 and X2.
c. Run a product past the suspect trigger.
d. Note whether the LED is turning on and off (or off and on).
e. If the LED is transitioning, the trigger is signalling. This indicates
that the trigger is probably installed correctly and is not defective
(refer to the following note). If the LED is not transitioning, continue
with step 2.
NOTE: Even if the trigger is signalling, the signal might be
intermittent if the alignment or sensitivity setting is marginal. If the
EPC-15 pattern control is not consistently generating a pattern set on
every product, refer to All Patterns Missing on Some Products in this
section.

2. Check the lens on the trigger and clean if necessary.
3. Check the alignment and sensitivity setting of the trigger. Refer to
Adjusting a Trigger in Installation and correct as necessary.
4. Check the continuity of the trigger wiring and correct. Refer to
Connecting Inputs and Outputs to Main Control Board in Installation.
5. Check for proper trigger voltage. Refer to Test Voltages in this
section.
6. If the trigger is still not sending an input signal, replace the trigger or
try another type of trigger. The trigger may be having difficulty
sensing product, especially if there is little difference in reflectivity
between products and the background.
7. If the LEDs do not transition with the new trigger installed, replace the
unit.

Nordson Glossary
Use this glossary for explanations of the technical and specialized terms
found in this manual.
Autoscaling
A feature of the EPC-15 pattern control that determines the line speed
given a known product length.
Auto Start
An optional setting that automatically places the EPC-15 in Run mode
when power is applied, and begins generating patterns when the first
product sensed by the trigger reaches the guns. If the auto start setting
is not activated, manually press the RUN key to start the generation of
pattern sets.
Bead
A continuous line of adhesive from one gun.
Bead Length
The distance, in millimeters, milliseconds, or inches (measured to the
nearest 0.1 in.), from the start to the end of the bead.
Bead Offset
The distance from the leading edge of the product to the beginning of the
bead. Refer also to Leading Edge.
Disable Status
Pattern generation is disabled by the remote inputs. When remote inputs
enable the system, the status will become RUN.
Display
The area on the operator panel that shows information for setting up,
operating, and monitoring the EPC-15.
Fault
Notification that a defect or problem has occurred in the EPC-15. When
a fault occurs, the word Fault and a fault code appear on the display. If
the system is running, the EPC-15 will stop generating patterns. Faults
cannot be cleared until the cause of the fault is corrected.
GTO
Gun-To-Trigger offset. The distance from the centerline of the gun nozzle
to the centerline of the trigger lens. The GTO for random length
programs must be manually entered.
Gun
The device that dispenses adhesive onto products. Also 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 and Output.

Glossary
Gun Actuator
The devise that opens and closes the gun. A gun actuator can be a
pneumatic solenoid valve or an electric gun driver, depending on the type
of guns used in the production facility.
Gun-to-Trigger Offset
Refer to GTO.
Interval
The distance from the start of one bead to the start of the next bead or, in
the case of stitched beads, the distance from the start of one sub-bead to
the start of the next sub-bead.
Leading Edge
The edge or face of the product that the trigger senses first on the
production line. This edge is also used as the starting point for the
bead-offset measurement. Refer also to Trailing Edge and Bead Offset.
Length
Refer to Bead Length.
Main Control Unit
The EPC-15 pattern control, which includes the main engine board, an
integral operator panel, and the enclosure.
Multiple Pattern Processing
The ability of the EPC-15 to remember up to four new products while
gluing another.
Normal Pattern Type
A pattern type generated by the EPC-15. The beads are placed off of the
leading edge of the product only.
Offset
Refer to Bead Offset or GTO.
Online Pattern Adjustment
A feature that provides quick adjustments to a pattern set as products run
on the production line. The feature also provides faster set ups for
patterns and corrects, on the spot, irregular patterns caused by machine
or product variations.
Operator Panel
The primary method of user interaction, including the display and keypad.
Output
A current or voltage sent from the EPC-15 pattern control that operates a
gun actuator. The EPC-15 pattern control has four independent outputs
for operating gun actuators.
Pattern
All the beads produced by a single gun. Enter settings for up to 8 beads
per pattern. Refer also to Pattern Set.
Pattern Set
All the patterns generated by a single program. Because the EPC-15
pattern control has four outputs for controlling gun operation, up to four
different patterns on any product can be generated.
Pattern Type
The EPC-15 can place three types of patterns: normal, random-length,
and stitched bead. Refer to Normal Pattern Type, Random-Length
Pattern Type, and Stitched Bead Pattern Type.

PLC
Programmable Logic Controller.
Power Supply
Equipment that converts a plant’s AC line voltage to DC voltage and
supplies it to the EPC-15 pattern control. The power supply is external to
the EPC-15 pattern control and is connected to it by wiring.
Product
Any item onto which adhesive is applied.
Program
All of the pattern settings and parameters for applying adhesive during a
single production run. Each program is identified by a program number
and stored in the controller memory. A program includes all settings in
both the Pattern mode and the Options mode (pattern type, trig min,
speed).
Program settings vary from one product to the next. However, system
settings are global and do not change from product to product.
Purge
The process of removing trapped air or debris from the melter or of
relieving system pressure by turning the gun(s) on. One or more guns
can be purged by pressing the PURGE key and the ENTER key on the
operator panel of the EPC-15 pattern control.
Quick Keys
DELETE, COPY, and PASTE keys. By pressing the SHIFT key and one
of these keys, use different shortcuts when entering or revising pattern
settings. The DELETE key is also used to clear trigger counts and
values.
Random Length Pattern Type
A pattern type generated by the EPC-15 pattern control. Random-length
places the pattern on the leading edge and a mirror image on the trailing
edge of the product.
Remote Inputs
The three inputs that may be used for remote program recall, or as
enable, disable, and lockout.
RUN Status
The operating mode used to start pattern generation. Place the controller
in the RUN mode by manually pressing the RUN key or by applying
power to the unit when the auto start feature is enabled.
Sensor
See Trigger.
Speed
The speed of the production line. In metric or English units, it converts
the distance values entered into time values that produce the pattern.
Stitched Bead Pattern Type
A pattern type generated by the EPC-15 pattern control. The stitching
feature reduces adhesive use by a percentage entered by the user. The
pattern control then determines the correct length and spacing of the
sub-beads in the bead pattern. Also available is the option of setting a
sub-bead interval (the distance from the start of one sub-bead to the
next). Refer also to Sub-Bead.

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
stitched beads.
Stop Status
The operating mode used to stop pattern generation. Place the controller
in the STOP mode by manually pressing the RUN key.
System Settings
All settings in the system mode. These are global to the unit and
therefore affect all programs.
Trailing Edge
The product edge that causes the trigger to stop sensing the product as it
passes by the trigger. It provides information that the EPC-15 pattern
control uses to perform such functions as generating random-length
patterns and auto scaling. Refer also to Leading Edge.
Trigger
A photosensor or switch that detects products travelling along the
production line. The EPC-15 pattern control can be equipped with one,
two, or three triggers depending upon application requirements.
