◆ Flow rate is independent of frequency 50/60 Hz.

❖ Flow rate increases with flow meters removed.

‡ The maximum fluid working pressure for the base machine without hoses is 3000 psi (21 MPa, 207 bar). If hoses

rated at less than 3000 psi are installed, the system maximum fluid working pressure becomes the rating of the
hoses. If 2000 psi hoses were purchased and installed by Graco, the working pressure for the machine is already
setup for the lower 2000 psi (14 MPa, 138 bar) working pressure by Graco. If the machine was purchased without
hoses and aftermarket hoses rated at or above 3000 psi are to be installed, see Adjust Motor Control Module
Selector Switch on page 27 for the procedure to setup the machine for higher rated hoses. The change in work­ing pressure is made by changing a rotary switch setting in the Motor Control Module. The minimum pressure rat­ing for hoses is 2000 psi. Do not install hoses with a pressure rating lower than 2000 psi.

Important Two-Component Material Information

WARNING

BURN HAZARD

Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe
burns:

• Do not touch hot fluid or equipment.

SPLATTER HAZARD

Hot or toxic fluid can cause serious injury if splashed in the eyes or on skin. During blow off of platen,
splatter may occur.

• Use minimum air pressure when removing platen from drum.

Important Two-Component Material Information

Isocyanate Conditions

Spraying or dispensing materials containing isocya­nates creates potentially harmful mists, vapors, and
atomized particulates.

Read material manufacturer’s warnings and material
MSDS to know specific hazards and precautions
related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufficient ventila­tion in the work area. If sufficient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.

To prevent contact with isocyanates, appropriate per­sonal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.

Material Self-ignition

Keep Components A (Red) and B(Blue) Separate

Cross-contamination can result in cured material in
fluid lines which could cause serious injury or dam­age equipment. To prevent cross-contamination of
the equipment’s wetted parts, never interchange
component A (Red) and component B (Blue) parts.

Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.

313875J 7

A (Red) and B (Blue) Components

Moisture Sensitivity of Isocyanates

Isocyanates (ISO) are catalysts used in two component
foam and polyurea coatings. ISO will react with moisture
(such as humidity) to form small, hard, abrasive crystals,
which become suspended in the fluid. Eventually a film
will form on the surface and the ISO will begin to gel,
increasing in viscosity. If used, this partially cured ISO
will reduce performance and the life of all wetted parts.

NOTE: The amount of film formation and rate of crystal­lization varies depending on the blend of ISO, the
humidity, and the temperature.

To prevent exposing ISO to moisture:

• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere. Never
store ISO in an open container.

• Keep the pump wet cups filled with IsoGuard

rier between the ISO and the atmosphere.

, part 24F516. The lubricant creates a bar-

• Use moisture-proof hoses specifically designed for
ISO, such as those supplied with your system.

• Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.

• Never use solvent on one side if it has been contam­inated from the other side.

• Always lubricate threaded parts with ISO pump oil
or grease when reassembling.

Changing Materials

• When changing materials, flush the equipment mul­tiple times to ensure it is thoroughly clean.

• Check with your material manufacturer for chemical
compatibility.

• Most materials use ISO on the A (Red) side, but
some use ISO on the B (Blue) side. See the follow­ing section.

A (Red) and B (Blue) Components

IMPORTANT!

Material suppliers can vary in how they refer to plural
component materials.

Be aware that when standing in front of the manifold on
proportioner:

• Component A (Red) is on the left side.

• Component B (Blue) is on the right side.

For all machines:

• The A (Red) side is intended for ISO, hardeners,
and catalysts.

• The B (Blue) side is intended for polyols, resins, and
bases.

NOTE: For machines with material volume ratios other
than 1:1, the higher volume side is typically the B (Blue)
side.

Power Line Voltage Surges

Power conversion equipment can be sensitive to voltage
fluctuations on incoming power. The Motor Control Mod­ule falls under the category of power conversion equip­ment because energy is stored on a capacitive bus and
then modulated to control a brushless motor. Engi­neered design takes this into account and withstands a
wide range of conditions, but it is possible for supplied
power to occasionally fall outside the tolerable range in
industrial plants with high-amperage reactive pulsed
loads such as welding equipment. If the tolerable range
is exceeded, an overvoltage condition is flagged and the
system will shut down in an alarm state to protect itself
and alert the user of unstable power. Excessive or
repeated overvoltage may permanently damage hard­ware.

The MAX-HOLD feature on a multimeter can be used to
determine peak DC voltage on the line. DC is the proper
setting, as opposed to AC, because peak voltage is the
critical parameter that affects the DC voltage level
stored on the capacitive bus in power conversion equip­ment. Reading should not regularly exceed approxi­mately 400VDC to avoid tripping the 420VDC alarm
level in the Motor Control Module. If power quality is sus­pect, power conditioning or isolation of the device(s)
causing poor power quality is recommended. Consult a
qualified electrician if there are any concerns about the
available power supply.

Adjust Motor Control Module Selector Switch

NOTICE

If the Motor Control Module is replaced, the selector
switch must be set prior to initial startup of the
Motor Control Module or damage may occur.

The Motor Control Module uses an 8-position selector
switch (S) to set system maximum working pressure.
See F

IG. 13.

The system can be configured to run in two pressure
ranges:

• 0-3000 psi (0-20.7 MPa, 0-207 bar): For systems
with all components rated to 3000 psi maximum
working pressure or higher.

• Do not install components rated to less than the
highest pressure in the selected pressure range.
For example, if the 0-2000 psi range is selected do
not install items rated less than 2000 psi. If the
0-3000 psi range is selected do not install items
rated less than 3000 psi. Doing so may lead to
overpressurization and ruptured components.

• High-pressure fluid from ruptured components will
pierce skin. This may look like just a cut, but it is a
serious injury that can result in amputation. Get
immediate surgical treatment.

Setup

• 0-2000 psi (0-13.8 MPa, 0-138 bar): For systems
with one or more component rated less than
3000 psi maximum working pressure. For example,
if the hoses are rated to 2500 psi, then the
0-2000 psi range must be used.

See the following table for MCM selector switch (S) posi­tion setting for each maximum working pressure.

Switch Position

MCM

2000 psi MWP 3000 psi MWP

B (Blue) 1 3

A (Red) 2 4

The factory setting for the Motor Control Module selector
switch is 2000 psi if the machine is shipped with no
hoses or hoses rated to 2000 psi maximum working
pressure. If the machine is shipped with hoses rated to
3000 psi maximum working pressure or higher then the
factory setting for the selector switch is 3000 psi.

The selector switch position will be properly set at the
factory for new systems. When a motor control module
is replaced, the selector switch must be set to the cor­rect setting by the user prior to initial startup.

To set the Motor Control Module selector switch:

1. Turn machine power off.

2. Remove the access cover (D). See F

IG. 13.

3. Set the selector switch (S).

4. Install access cover (D).

IG. 13

To change the maximum working pressure rating of the
system in the field, all outlet components including
hoses and dispense valve must be rated at or above the
new system maximum working pressure rating. For
example, if the new system rating will be 3000 psi, all
system components must be rated to at least 3000 psi
maximum working pressure.

Machine Operation Overview

Operation

Ramp Up Feature

The purpose of the ramp up feature is to enable dis­pensing at the correct ratio but at a reduced flow rate
when materials are too thick to dispense at the correct
flow rate. As the fluid warms up due to the friction of
moving through the system, the Ramp Up feature will
slowly increase the flow rate until the desired flow rate is
achieved. After a period of idle time the system will cool
down and the fluids will not be as warm while dispens­ing, which may result in the Ramp Up feature being acti­vated.

While the system is dispensing, the ramp up feature
monitors the torque supplied to the B (Blue) pump to
verify it does not apply more torque than the pump can
handle. If it does, it will reduce the flow rate in both
pumps to maintain the required dispense ratio. As the
system warms up and material thickness decreases, the
ramp up feature will increase the flow rate until the
desired flow rate is achieved.

NOTE: Because the B (Blue) side is the high volume
side, it is closer to its maximum flow rate capacity than
the A (Red) side pump.

Learning Mode

When a flow rate or dispense ratio is requested that the
machine has not learned, the system will use the pump
volume of each pump to estimate the pump velocities
needed then Learn mode will be used to adjust them to
the correct flow rates. The system will begin dispensing
at the estimated pump velocity and each stroke per­formed will be used to gather information and adjust the
velocity. After a number of strokes, the system will have
sufficient data to accurately dispense at the desired set­point and Learning mode will be exited.

When Learn mode is active, a “Learning New Set Point”
advisory is generated and the yellow light on the light
tower is illuminated. After Learn mode is complete, the
advisory is cleared.

Because a base purge is done before the system is shut
down, the first dispense after the system is turned on is
always initiated at a reduced flow rate. The ramp up fea­ture will then increase the flow rate as described in the
previous paragraph. Also, after ten minutes of idle time
the first dispense will be at a reduced flow rate followed
by the flow rate ramp up.

When the ramp up feature reduces the flow rate, a “Sys­tem Dispensing Below Requested Set Point” advisory is
generated and the yellow advisory lamp on the light
tower is illuminated. If the system is able to achieve the
desired flow rate the advisory is cleared.

to be decreased. For most materials at 68°F (20°C) at a
2:1 to 3:1 ratio, a maximum flow rate of 335 g/s or 335
cc/s can be expected. The machine should not be oper­ated much below 120 g/s or 120 cc/s at a 2:1 to 3:1 ratio.

Operation

41. Weigh the two buckets and use the net weight of
each dispensed material to calculate the actual ratio
of the dispensed material.

42. If the calculated ratio of the weighed materials does
not match the ratios displayed on the ADM, go to
step 1 to re-calibrate the flow meters.

43. If the calculated ratio of the weighed materials
matches the ratio displayed on the ADM, then navi­gate to the System 3 screen and change the ratio
alarm percentage to the desired percentage.

44. If at any point in the future the ratio, flow rate, or
ambient temperature changes from what was used
while performing this procedure, go to step 1.

NOTE: If the ratio or flow rate is changed to a ratio or
flow rate that has not been calibrated by performing this
procedure, the system will generate a “Learning New
Setpoint” advisory. The system usually produces a good
dispense ratio during the learning process however the
advisory is generated to inform the user of the condition.
The system can store calibration data in its memory for
up to five different flow rates and ratios.

NOTE: If the ambient temperature changes significantly
from the ambient temperature seen while performing
this calibration procedure, the system will need to
“learn” the new temperature and the flow rate may need
to be decreased. If the original flow rate was 325 g/s at
68°F (20°C) and the temperature is now 46°F (8°C), the
user may want to select a flow rate of 150 g/s or
150 cc/s. The machine will not automatically be aware of
the temperature change but it will try to find the correct
dispensing properties to compensate for the new tem­perature. If the ambient temperature changes signifi­cantly, go to step 1. It is important for the system to learn
the new temperature because typical paste materials
increase viscosity significantly as the temperature
decreases below 68°F (20°C).

Acceptable Size and Duration of Power Line Voltage Fluctuations

The Motor Control Module is designed to withstand volt­age fluctuations from the incoming power supply. If the
incoming power supply goes outside of the tolerable
range, an over-voltage condition is flagged and the sys­tem shuts down in an alarm state. Excessive or
repeated over-voltage may permanently damage hard­ware. The chart below shows the permissible magnitude
and duration of temporary over-voltage events. Consult
a qualified electrician if there are any concerns about
the available power supply.

Appendix E - USB Operation

NOTICE

Low-quality USB stick drives may lead to burning
out the USB port on the ADM. Use only high-quality
USB stick-drives.

Overview

There are 3 main uses for the USB.

• Ability to download a log of up to the past 50,000
errors, events, or jobs that can contain over 150,000
snapshots of critical dipsense information.

• Download, modify, and upload custom language
files

• Download and upload system configurations

• This data includes most user-selectable and

user-configurable settings.

• This data does not include pump counters, error

and event logs, shot and sequence counters

USB Options

The only options for USB on the ADM are in Advanced
#4, see page 64.

The second option is the Erase icon which will reset the
last download date to a time where all logs can be
downloaded. This will allow the user to download all
USB log entries, which may take over 2 hours if the log
files are full. The ADM does not monitor the USB logs to
alert the user when data may be overwritten. In order to
minimize download times and the risk of losing data it is
recommended that the user download the logs every 2
weeks or more often if the machine is used during more
than one full shift a day.

Download Log Files

If the “Enable Downloading of USB Logs” option is
checked, a USB stick-drive can be used to download the
log files.

To download the log files, insert a high-quality USB
stick-drive into the USB port in the bottom of the ADM.
The ADM will automatically begin downloading the log
files as well as the custom language file (DISP­TEXT.TXT) and the system settings file (SET­TINGS.TXT). The status of the download will be shown
in the Status bar. If an error occurs during download,
remove the USB stick-drive then re-insert.

The first option is a checkbox that enables or disables
the downloading of the Error Event and Shot Data log
files. The Shot Data log runs during all operating modes.

Log Files, Folder Structure

Appendix E - USB Operation

F

IG. 19: DOWNLOAD, DATAxxxx Folders

Each time a stick-drive is inserted into the ADM USB port, a new folder named DATAxxxx is created. The number at
the end of the folder name is incremented each time a stick-drive is inserted and data is transferred through the USB.
In each DATAxxxx folder there are three log files. They are formatted as .csv (comma separated value) files and can
be opened by most text editors or data processing programs such as Excel.

Example 1-ERROR File

The 1-ERROR file is the Errors and Events log file.

Transfer System Settings

Appendix E - USB Operation

Use the following process to transfer system settings
from one machine to another.

1. Insert a high-quality USB stick-drive into the ADM
USB port on the system with the settings to be
transferred. Once the download is complete the
SETTINGS.TXT file will be located in the “DOWN­LOAD” folder.

NOTICE

The user should never attempt to modify the SET­TINGS.TXT file in any way. Graco is not responsible
for damages caused by an improperly modified
setup file.

2. Plug the USB stick-drive into a computer.

3. Navigate to the DOWNLOAD folder.

4. Copy the SETTINGS.TXT file from the DOWNLOAD
folder into the UPLOAD folder.

5. Remove the USB stick-drive from the computer and
install it into the ADM USB port for the second
machine. The software will automatically begin
updating.

NOTE: Before the update begins the ADM automatically
shuts down the system, aborting any in-progress dis­pensing. When the software is updating a pop-up box
will appear to inform the user of the update and the sys­tem will lock. Once the update is complete the ADM will
tell the user to cycle power to apply the updates.

6. When the software is done updating, remove the
USB stick-drive.

7. Turn the Main Power Switch to the OFF position
then back to the ON position.

8. Plug the USB stick-drive into a computer.

9. Navigate to the UPLOAD folder and remove the
SETTINGS.TXT file.

NOTE: Immediately after uploading the settings, remove
the SETTINGS.TXT file from the UPLOAD folder to pre­vent accidental loss of data the next time the USB
stick-drive is inserted into the ADM USB port. If there is
a SETTINGS.TXT file in the UPLOAD folder when the
USB stick-drive is inserted into the ADM USB port the
software will automatically begin updating.

Appendix E - USB Operation

Update Custom Language

Use the following process to customize the text on the
ADM. The language file DISPTEXT.TXT can be modi­fied in Excel but must be saved as a Unicode Text file
with the extension .TXT in order for it to properly import.

1. Insert a high-quality USB stick-drive into the ADM
USB port on the system with the settings to be
transferred. Once the download is complete the
DISPTEXT.TXT file will be located in the “DOWN­LOAD” folder.

2. Plug the USB stick-drive into a computer.

3. Navigate to the DOWNLOAD folder.

4. Copy the DISPTEXT.TXT file from the DOWNLOAD
folder to your computer.

5. Use any data processing software such as Excel to
edit the DISPTEXT.TXT file.

a. In the first column, locate the string to change.

b. In the second column of the same row, enter the

new string.

NOTE: Immediately following uploading the language
file, remove the DISPTEXT.TXT file from the UPLOAD
folder to prevent accidental loss of data the next time the
USB stick-drive is inserted into the ADM USB port. If
there is a DISPTEXT.TXT file in the UPLOAD folder
when the USB stick-drive is inserted into the ADM USB
the software will automatically begin updating.

c. Save the file as a Unicode Text file. The name

must remain “DISPTEXT.TXT”.

6. Copy the edited DISPTEXT.TXT file into the
UPLOAD folder.

7. Remove the USB stick-drive from the computer and
insert it into the ADM USB port. The software will
automatically begin updating.

NOTE: Before the update begins the ADM automatically
shuts down the system, aborting any in-progress dis­pensing. When the software is updating a pop-up box
will appear to inform the user of the update and the sys­tem will lock. Once the update is complete the ADM will
tell the user to cycle power to apply the updates.

8. When the software is done updating, remove the
USB stick-drive.

9. Turn the Main Power Switch to the OFF position
then back to the ON position.

10. Plug the USB stick-drive into a computer.

11. Navigate to the UPLOAD folder and remove the
DISPTEXT.TXT file.
