mix chamber sizes may be less.

** Cycle rate should be between 8 and 20 cycles per minute. Max flow rate is determined for continuous service at
120°F (39°C) at stated cpm and pressure. Higher cycle rates are possible at lower temperatures/pressures and
intermittant use. Lower cycle rates are possible, but should be tested under application conditions.

★

Dispense rate in excess of max flow and pressure may result in a machine shutdown due to elevated temperature
of the hydraulic system, resulting in a thermal shutdown (T4H1).
approved.

‡ The maximum fluid working pressure for the base machine without hoses is 3000 psi (20.7 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 (13.8 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 instruction manual 3A1276 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

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

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

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

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 ISO lube pump reservoir (if installed) filled
with IsoGuard Select™, part 24F516. The lubricant
creates a barrier between the ISO and the atmosphere.

•

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.

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.

3A2175A

A (Red) and B (Blue) Components

Changing Materials
•

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

•

Always clean the fluid inlet strainers after flushing.

•

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.
If one of the materials being used is moisture-sensitive, that material should always be in the A (Red)
side.
The B (Blue) side is intended for polyols, resins, and
bases.

For HFRS Systems:
The high volume material is typically the ISO and is
located on the A (Red) side. Some material chemistries
may have an ISO which is the low volume material. The
ISO must always be in the A (Red) side containing the
Isolube.
For HFRL Systems:
The high volume material will always be the B (Blue)
side.Typical Installation

Dispense Valve Overview

Dispense Valve Overview
The HFRL and HFRS systems will be provided exclusively with MD2 dispense valves.
The MD2 dispense valve is an example of a solenoid
controlled dispense valve. When the trigger is pulled the
signal requests the dispense to start. When the machine
sees the signal, fluid rises to dispensing pressure and
the valve is opened to begin dispensing. When the trigger is released, the solenoid signals that the dispense is
finished.

Setup

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 chart below shows the permissible magnitude and
duration of temporary over-voltage events:

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.
Power Line Test Steps with Multimeter
a. Set multimeter to “DC voltage”.
b.

Connect multimeter probes to supplied power
line.

Press “Min Max” successively to show the peak
positive and negative DC voltages.

d. Confirm readings do not exceed 400VDC
(Motor Control Module alarm issued at
420VDC).

Operation

2. Calibrate HFR
The HFR calibration procedure is a two step process.
The first step, Learn Mode, must be performed whenever the pump line is rebuilt or if any other maintenance
is performed that may affect the mechanical tolerances
in the pump line. If the machine does not appear to be
utilizing the full extent of the pump stroke, or if the
machine appears to be contacting the end of the
hydraulic cylinder, follow the Learn Mode procedure.
The Learn Mode procedure will teach the system the
mechanical limits of travel.
Learn Mode Procedure:
a. Navigate to the Calibration screen.
b.

Place a waste container below the dispense
valve. The next steps will cause the machine to
dispense material.

If the system is to be used in a Time or Volume Dispense Mode, system calibration is complete after the
Learn Mode procedure described above. However, if the
system is to be used in Weight Dispense mode and the
application requires that the dispense amount be accurate and consistent then the weight calibration procedure below must be followed.
Weight Calibration Procedure:
NOTE: Only perform Weight Calibration procedure if the
system will be run in Weight Dispense mode.
The Weight Calibration procedure must be run with the
system production-ready. Orifice sizes and hose lengths
must be finalized, material should be at temperature and
any conditioning zones that will be on during production
should be turned on. Any variation in system setup
between when this procedure is run and the production
environment will result in a decrease in system dispense
accuracy.

Flushing

•

To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of dispense
gun firmly to the side of a grounded metal pail, then
trigger gun.

Flush equipment only in a well-ventilated area. Do not
dispense flammable fluids. Do not turn on heaters
while flushing with flammable solvents.
•

Flush out old fluid with new fluid, or flush out old
fluid with a compatible solvent before introducing
new fluid.

•

Use the lowest possible pressure when flushing.

•

All fluid components are compatible with common
solvents. Use only moisture-free solvents. See
Accessories on page 91 for list of wetted components to verify compatibility of solvent with wetted
materials. See solvent manufacturers information for
material compatibility.

•

3A2175A

Operation

Adjusting Material Inlet Pressure
Using the Material Regulator

8. Place the pressure relief valve on the manifold into
the recirculation position.
9. Slowly increase the air pressure on the material regulator to allow material to flow though the pump and
out the bleed hose. The required material pressure
will vary depending on the material viscosity and
flow rate.

NOTICE
Care must be taken when applying pressure to systems equipped with a material pressure regulator
on the inlet assembly. Read both operation and service manuals for the pump/ram supply system and
the material pressure regulator prior to loading
material to the HFR system.

10. Once material is flowing from the bleed hose, slowly
decrease pressure on the material regulator until
flow stops.
11. Gradually increase pressure to the material regulator until material begins to flow again
12. When material begins to flow out of the bleed port,
close the pressure relief valve.

Use the following procedure to adjust the material pressure to the system. This process assumes that the supply system consisting of a supply pump and outlet hose
has already been loaded and primed and is ready to
provide material to the pump inlet.
1. Verify the air pressure is provided to the material
regulators and that the air gauge on both regulators
are functioning properly.
2. Adjust the air pressure on both material regulators
so that there is no air pressure on them and that the
regulator pressure gauge reads zero.
3. Verify that the material supply pump does not provide material pressure in excess of 3000 psi
(21 MPa, 207 bar).
NOTICE
Although the material regulator itself is rated for
5000 psi (35 MPa, 345 bar) (, the assembly provided is only rated for do not exceed 3000 psi
(21 MPa, 207 bar)

NOTE: Record the material pressure gauge reading.
Use this pressure as a starting point for adjusting the
material feed pressure to meet application requirements.
NOTE: As a general rule for high viscosity materials, the
dispense pressure must exceed the material inlet pressure by 2 to 3 times. Therefore, if the maximum dispense pressure is 2500 psi (17 MPa, 172 bar), the inlet
pressure should be no more than 1250 psi (9 MPa,
86 bar). For lower viscosity, flowable materials, the dispense pressure should exceed the inlet pressure by 3-4
times. Use only enough feed pressure to adequately
feed the HFR pumps.
NOTICE
The material pressure regulator is not self relieving.
Reducing the material pressure at the regulator will
not effect the pressure reading until the accumulated down stream pressure is relieved. Perform
Pressure Relief Procedure on page 38.

4. Verify that there is no pressure in the material supply pump.
5. Connect the feed hose from material supply system
to the inlet assembly and make sure all fittings are
fluid tight.
6. Gradually increase the air pressure to the supply
pump to provide no more than 3000 psi (21 MPa,
207 bar) material pressure to the inlet regulator
assembly.
7. Place a container at the outlet of the relief lines from
the manifold assembly and secure the lines in place.

Operation

Pressure Balancing Using the
Orifice Valve Assemblies

1. Before installing, insert the allen wrench into the hex
end of the orifice valve to adjust the needle position.
2. Verify the needle valve is in the fully open position
by turning counter-clockwise until rotation stops.
After installation, the needle valve can be turned
clockwise to further increase pressure.

The MD2 valve for HFRL and HFRS systems is provided
with orifice valve blocks on both of the inlet ports. The
orifice blocks are assembled at the factory with no orifices installed. An orifice kit is provided with a range of
orifice sizes to balance pressures. The orifice size is
etched on the side of the orifice body and there are two
orifices provided in each size. One of the orifices in each
size will be stamped on the hex end with an "A". Use the
orifices stamped with the "A" in the RED side orifice
block. The orifices with no letter etched on the hex end
are to be used on the BLUE side.

B ORIFICE

A ORIFICE
SIZE

LOCATION

NOTE: Always run the material first at the desired flow
rate with no orifice valves installed to evaluate the dispense pressures generated for each material.
NOTE: Appropriate orifice valve selection is essentially
done by trial. The following can help determine if it is
necessary to increase the outlet pressure and help
select an orifice.
a. The outlet pressure for heavy-paste viscosity
materials should be at least 2 times higher than
the z-pump feed pressure (as determined by the
material pressure regulator). Max outlet pressure is equal to 3000 psi (21 MPa, 207 bar) and
the feed pressure should be below 1500 psi
(10 MPa, 103 bar).
b.

The outlet pressure for lower viscosity-flowable
materials should be 3-4 times higher than the
z-pump feed pressure. Dispense pressures for
this viscosity range should be in the 750 psi
(5 MPa, 52 bar) to 1000 psi (7 MPa, 69 bar)
range.

The outlet pressures of both material hoses
should be as close as possible to each other
and within a suggested range of 10%. See System Screen 3, page 63.

3. Install orifice valves only if the outlet pressure needs
to be increased. See Maintenance starting on page
43 for details.
ADJUSTMENT

Orifices can be installed in one or both orifice blocks as
a tool to increase the outlet pressure in the corresponding material hose. The orifice valves are equipped with a
needle valve that can be adjusted with the provided
allen wrench.

3A2175A

4. If rule a and b above are met by both materials,
install an orifice valve in the lower pressure side,
only if required to balance the outlet pressures.
5. If neither rule a or rule above are met by either
material, install an orifice valve in both orifice blocks
to raise the pressure and allow pressure balancing.

Operation

NOTE: In general, the flow area ratio of the orifice
valves should be equal to the material ratio, but it will
also be influenced by differences between "A" and "B"
material viscosities and flow characteristics. For flowable materials, start with a smaller orifice combination to
increase pressure. For heavy viscosity, paste materials,
start with a larger orifice combination. It is desirable for
the orifice to do the majority of the pressure adjustment,
as this will result in the most stable system. Adjustments
of the needle valve (if used) will require periodic adjustment.
NOTICE
Not properly maintaining the pressure differential
between inlet and dispense pressures may cause
inconsistent pump output. Adjust the needle valves
periodically to maintain pressures.

FIG. 17. Fluid Inlet Strainer

Check the condition of the A (Red) pump IsoGuard
Select fluid daily. Change the fluid if it becomes a gel, its
color darkens, or it becomes diluted with isocyanate.
Gel formation is due to moisture absorption by the pump
IsoGuard Select fluid. The interval between changes
depends on the environment in which the equipment is
operating. The pump lubrication system minimizes
exposure to moisture, but some contamination is still
possible.
Fluid discoloration is due to continual seepage of small
amounts of isocyanate past the pump packings during
operation. If the packings are operating properly, IsoGuard Select fluid replacement due to discoloration
should not be necessary more often than every 3 or 4
weeks.
To change pump IsoGuard Select fluid:
1. Perform Pressure Relief Procedure on page 38.
2. Remove fittings from IsoGuard Select fluid cylinder
inlet and outlet ports. Keep supply tube (ST), return
tube (RT), and leak management tube (LT) connected to the fittings.
3. Carefully place ends of tubes with fittings still connected into an empty pail to drain IsoGuard Select
fluid.
4. Lift the IsoGuard Select fluid reservoir (LR) out of
the bracket (RB) and remove the container from the
cap. Holding the cap over a suitable container,
remove the inlet check valve and allow the IsoGuard
Select fluid to drain. Reattach the check valve to the
inlet hose. See FIG. 18.
5. Drain the reservoir and flush it with clean IsoGuard
Select fluid.
6. When the reservoir is flushed clean, fill with fresh
IsoGuard Select fluid.

3A2175A

Maintenance

7. Thread the reservoir onto the cap assembly and
place it in the bracket (RB).
8. Push the supply tube (ST) approximately 1/3 of the
way into the reservoir.
9. Push the return tube (RT) into the reservoir until it
reaches the bottom.
NOTE: The return tube must reach the bottom of the
reservoir, to ensure that isocyanate crystals will settle to
the bottom and not be siphoned into the supply tube and
returned to the pump.

5. With check valve arrow pointing away from the IsoGuard Select fluid cylinder, install check valve in end
of outlet tube.
6. Install tubes into reservoir and install reservoir into
holder.

Clean Orifice Valves
Only for MD2 Valve using Orifice Block Kit 24E505 and
an orifice.
NOTE: 24E505 does not come with an orifice.
1. Follow Pressure Relief Procedure in MD2 valve
manual.
2. Use 5/16 in. nut driver to remove orifices.
NOTICE
To prevent cross-contamination of the orifices, do not
interchange A component and B component parts.

Home Screen, Sequence Mode

Home Screen, Operator Mode

This mode allows the user to select one of five
sequences (A-E). The progress bar on the bottom of the
screen shows the progress of a shot dispensing from
the selected sequence. See Sequences Screen on
page 59 for information about editing sequence definitions.

This mode allows users to set a pressure or flow rate to
dispense material without using predefined shot information. Pressure or flow rate availability is dependent
on the Control Mode selection, see System Screen 2
on page 62.

To use a predefined sequence:
1. Ensure that the machine is in Sequence Mode.
2. Press the sequence letter/position selection button.
3. Use the left and right arrows to toggle between letter
and position selection. When selecting a sequence
letter (A-E), use the up and down arrow keys to
scroll through the available letters. When selecting a
sequence position, type in the desired position with
the numeric keypad. The system will reject invalid
letter/position selections.
4. Press the enter key to accept the sequence letter/position.

To edit the pressure or flow rate, press the
button.
The value to change will now be highlighted. Type the
new value then press the Enter button

to accept it.

The machine will begin dispensing at the set pressure or
flow rate when the dispense button is pressed and will
stop dispensing when it is pressed again. If a foot switch
is installed, the machine will dispense and continue to
dispense until the foot switch is released. If the foot
switch is used with a Mix Head installed a foot switch
press will start the pre-dispense timer and dispense
material when the timer expires. Another foot switch
press will terminate the dispense and start the post dispense timer.

5. Press the Dispense button to begin dispensing.

Appendix F - USB Operation
Overview

Download Log Files

There are 3 main uses for the USB on a GMS system

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

•

•
•

Ability to download a log of the past 50,000 errors
and events and a shot log that can contain over
250,000 snapshots of critical dispense information
Ability to download, modify, and upload custom language files
Ability to 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

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 (SETTINGS.TXT).
The status of the download will be shown in the Status
bar.

USB Options
The only options for USB on the ADM are in Advanced
Screen 2, see page 67.

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 recirculation,
shots, and operator modes.
The second option is the Erase icon which will reset the
last download date to a time where all logs can be
downloaded, 10/01/09. This will allow the user to download all the USB log entries, which may take over 2
hours if the log files are full. Currently the ADM does not
monitor the USB logs and alert the user when data may
be overwritten so 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.

Appendix F - USB Operation

Log Files, Folder Structure

FIG. 24: 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 downloaded or uploaded. In each DATAxxxx folder there is
two 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.

Transfer System Settings

Use the following process to transfer system settings
from one machine to another.
1. Insert a high-quality USB stick-drive into the 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.

NOTE: Before the update begins the ADM automatically
shuts down the system, aborting any in-progress dispensing. When the software is updating the system 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. Once this box appears it is safe to remove the
drive before cycling power.
6. When the software is done updating, remove the
USB stick-drive from the ADM USB port and install
in a computer.
7. 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 try to update the ADM.

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.

Appendix F - 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 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.

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
port the software will try to update the ADM.

2. Plug the USB stick-drive into a computer.
3. Navigate to the DOWNLOAD folder.
4. Copy the DISPTEXT.TXT file from the DOWNLOAD
to your computer.
5. Use any data processing software such as Excel to
edit the DISPTEXT.TXT file. When done editing
save the file as the “Unicode Text” format. See
Example DISPTEXT.TXT File on page 90.
a. In the first column, locate the string to change.
b.

In the second column of the same row, enter the
new string.

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
install 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 the system 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. Once this box appears it is safe to remove the
drive before cycling power.
8. When the software is done updating, remove the
USB stick-drive from the ADM USB port and install
in a computer.
9. Navigate to the UPLOAD folder and remove the
DISPTEXT.TXT file.
