HFR-Laminate (HFRL)

HFRL models are designed for use with low viscosity, unheated urethane laminating adhesives at flow rates of up to

30 cc/sec (4 lb/min).

* Full load amps with all devices operating at maximum capabilities. Fuse requirements at various flow rates and

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 pur-

chased without hoses and aftermarket hoses rated at or above 3000 psi are to be installed, see instruction man-

ual 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.

Isocyanate Conditions

Material Self-ignition

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 crystal-

lization 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 atmo-

sphere.

• 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 contam-

inated from the other side.

• Always lubricate threaded parts with ISO pump oil

or grease when reassembling.

Spraying or dispensing materials containing isocya-

nates 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 ventila-

tion 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 per-

sonal protective equipment, including chemically

impermeable gloves, boots, aprons, and goggles, is

also required for everyone in the work area.

Some materials may become self-igniting if applied

too thickly. Read material manufacturer’s warnings

and material MSDS.

Cross-contamination can result in cured material in

fluid lines which could cause serious injury or dam-

age equipment. To prevent cross-contamination of

the equipment’s wetted parts, never interchange

component A (Red) and component B (Blue) parts.

A (Red) and B (Blue) Components

3A2175A 15

Changing Materials

• When changing materials, flush the equipment mul-

tiple 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 follow-

ing 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-sensi-

tive, 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

28 3A2175A

Dispense Valve Overview

The HFRL and HFRS systems will be provided exclu-

sively 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 trig-

ger is released, the solenoid signals that the dispense is

finished.

Power Line Voltage Surges

Power conversion equipment can be sensitive to voltage

fluctuations on incoming power. The Motor Control Mod-

ule falls under the category of power conversion equip-

ment because energy is stored on a capacitive bus and

then modulated to control a brushless motor. Engi-

neered 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 hard-

ware.

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 equip-

ment. Reading should not regularly exceed approxi-

mately 400VDC to avoid tripping the 420VDC alarm

level in the Motor Control Module. If power quality is sus-

pect, 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.

c. 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).

The chart below shows the permissible magnitude and

duration of temporary over-voltage events:

2. Calibrate HFR

The HFR calibration procedure is a two step process.

The first step, Learn Mode, must be performed when-

ever 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.

c. Press the go right button and then the dis-

pense button . The pump will travel to the

right most extreme position.

d. After the pump stops moving, press the go left

button and then press the dispense

button . The pump will travel to the left most

extreme position.

e. After the pump stops moving, press the con-

tinue button to go on to the next step in the

calibration process or the page back button

to return to the main Calibration screen.

NOTE: During this process, the system learned the

mechanical limits of travel. If the pump did not reach

both the left and right extreme limits for any reason,

repeat the procedure.

If the system is to be used in a Time or Volume Dis-

pense 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 accu-

rate and consistent then the weight calibration proce-

dure 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.

a. Navigate to the Weight Calibration screen .

b. Navigate to the Cal. Setpoint text box then enter

the desired set point (pressure or flow, based on

selected Control Mode).

c. Press .

d. Put a waste container under the dispense valve.

e. Press or the footswitch to start the system

characterization process. The pump will start to

operate at the entered setpoint until it learns the

proper control parameters, then repeat the pro-

cess at 60% of that value. When it is complete,

the icon will change back to .

Flushing

• 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 compo-

nents to verify compatibility of solvent with wetted

materials. See solvent manufacturers information for

material compatibility.

• To flush feed hoses, pumps, and heaters separately

from heated hoses, set PRESSURE RELIEF/DIS-

PENSE valves (SA, SB) to PRESSURE

RELIEF/CIRCULATION . Flush through bleed

lines (N).

• To flush entire system, circulate through gun fluid

manifold (with manifold removed from gun).

• To prevent moisture from reacting with isocyanate,

always leave the system dry or filled with a mois-

ture-free plasticizer or oil. Do not use water. See

Important Two-Component Material Information

on page 14.

•Solvent pails used when flushing: follow your local

code. Use only metal pails, which are conductive,

placed on a grounded surface. Do not place pail on

a nonconductive surface, such as paper or card-

board, which interrupts grounding continuity.

•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.

Adjusting Material Inlet Pressure

Using the Material Regulator

Use the following procedure to adjust the material pres-

sure to the system. This process assumes that the sup-

ply 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 pro-

vide material pressure in excess of 3000 psi

(21 MPa, 207 bar).

4. Verify that there is no pressure in the material sup-

ply 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.

8. Place the pressure relief valve on the manifold into

the recirculation position.

9. Slowly increase the air pressure on the material reg-

ulator 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.

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 regula-

tor until material begins to flow again

12. When material begins to flow out of the bleed port,

close the pressure relief valve.

NOTE: Record the material pressure gauge reading.

Use this pressure as a starting point for adjusting the

material feed pressure to meet application require-

ments.

NOTE: As a general rule for high viscosity materials, the

dispense pressure must exceed the material inlet pres-

sure by 2 to 3 times. Therefore, if the maximum dis-

pense 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 dis-

pense pressure should exceed the inlet pressure by 3-4

times. Use only enough feed pressure to adequately

feed the HFR pumps.

NOTICE

Care must be taken when applying pressure to sys-

tems equipped with a material pressure regulator

on the inlet assembly. Read both operation and ser-

vice manuals for the pump/ram supply system and

the material pressure regulator prior to loading

material to the HFR system.

NOTICE

Although the material regulator itself is rated for

5000 psi (35 MPa, 345 bar) (, the assembly pro-

vided is only rated for do not exceed 3000 psi

(21 MPa, 207 bar)

NOTICE

The material pressure regulator is not self relieving.

Reducing the material pressure at the regulator will

not effect the pressure reading until the accumu-

lated down stream pressure is relieved. Perform

Pressure Relief Procedure on page 38.

Pressure Balancing Using the

Orifice Valve Assemblies

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 ori-

fices 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.

Orifices can be installed in one or both orifice blocks as

a tool to increase the outlet pressure in the correspond-

ing material hose. The orifice valves are equipped with a

needle valve that can be adjusted with the provided

allen wrench.

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.

NOTE: Always run the material first at the desired flow

rate with no orifice valves installed to evaluate the dis-

pense 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 pres-

sure 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.

c. The outlet pressures of both material hoses

should be as close as possible to each other

and within a suggested range of 10%. See Sys-

tem 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.

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

42 3A2175A

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 flow-

able 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 adjust-

ment.

* Item included in kit 24E250

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.

Fluid Inlet Strainer Screen

(Not included on HFRS systems)

The inlet strainers filter out particles that can plug the

pump inlet check valves. Inspect the screens daily as

part of the startup routine, and clean as required. The

standard strainer is 20 mesh.

Use clean chemicals and follow proper storage, transfer,

and operating procedures, to minimize contamination of

the A-side screen.

NOTE: Clean the A-side screen only during daily

startup. This minimizes moisture contamination by

immediately flushing out any isocyanate residue at the

start of dispensing operations.

1. Perform Pressure Relief Procedure on page 38.

2. Close the fluid inlet valve at the pump inlet and shut

off the appropriate feed pump. This prevents mate-

rial from being pumped while cleaning the screen.

3. Place a container under the strainer manifold (59d)

to catch fluid. Remove the strainer plug (59j).

4. Remove the screen (59g) from the strainer manifold.

Thoroughly flush the screen with compatible solvent

and shake it dry. Inspect the screen. If more than

25% of the mesh is blocked, replace the screen.

Inspect the gasket (59h) and replace as required.

5. Ensure the pipe plug (59k) is screwed into the

strainer plug (59j). Install the strainer plug with the

screen (59g) and gasket (59h) in place and tighten.

Do not overtighten. Let the gasket make the seal.

IsoGuard Select™ System

(Not included on HFRS systems)

NOTE: The IsoGuard Select system is included on all HFRL

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, Iso-

Guard 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) con-

nected to the fittings.

3. Carefully place ends of tubes with fittings still con-

nected 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.

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.

Prime IsoGuard Select Fluid Cylinder

Ensure that the IsoGuard Select fluid cylinder outlet

faces upward for air to exhaust.

1. Install IsoGuard Select fluid cylinder inlet fitting and

inlet tube into bottom of cylinder. The inlet tube is

the tube with a check valve installed in it which

points in the direction of flow towards the IsoGuard

Select fluid cylinder.

2. Install IsoGuard Select fluid cylinder outlet fitting

and outlet tube into top of cylinder. The outlet tube is

the tube with a check valve installed in it which

points in the direction of flow away from the Iso-

Guard Select fluid cylinder.

3. Remove check valve from end of outlet tube.

4. Use funnel to pour IsoGuard Select fluid into tube to

fill cylinder.

5. With check valve arrow pointing away from the Iso-

Guard 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.

3. Remove cap from orifice.

NOTE: The cap is held in place with reverse threads.

4. Remove needle from orifice. Thoroughly inspect all

o-rings and replace if necessary.

5. If necessary, use drill bit that is the same size as the

orifice to drill out the orifice. Orifice size is marked

on the orifice.

6. Liberally lubricate all o-rings.

7. Reassemble in reverse order. Torque orifices into

fluid housing to 20-30 in-lb (2.26-3.39 N•m).

brate HFR on page 36 for how and when to use this

screen to calibrate the machine.

System Screen 1

This screen allows the user to set important system set-

tings. Control Mode can be set to Pressure or Flow. With

Control Mode set to Pressure, the machine will adjust

dispense flow rate in order to maintain the requested

pressure. With Control Mode set to Flow, the machine

will dispense at a continuous flow rate regardless of

pressure fluctuations unless pressure alarm conditions

occur.

Dispense Mode can be set to Time, Volume, or Weight.

Dispense Mode controls how displayed amounts are

measured. If Dispense Mode is set to Weight, then the

machine dispenses until the desired weight of material

is dispensed. See Calibrate HFR on page 36 for more

information.

Pump sizes and inlet pressures must be entered on this

screen.

If pump sizes and inlet pressures are not entered prop-

erly, system performance will be affected. The inlet pres-

sure must be set to the maximum feed pressure that will

be seen by that side of the machine.

The maximum working pressure for the machine is dis-

played on this screen. The maximum working pressure

is dependent on the installed hoses and dispense valve.

The maximum working pressure is set to the lowest

rated system component. If 2000 psi hoses are installed

and the maximum working pressure displayed is not

2000 psi, see manual 313998 for instructions to set the

maximum working pressure for hoses. If the installed

dispense valve rating is below the maximum working

pressure shown here, verify the correct dispense valve

is selected on System Screen 2.

System Screen 2

This screen allows the user to set the Gel Timer proper-

ties and set which items are installed on the machine.

When enabling the Gel Timer, the user must select one

of the 100 available shot definitions to use as the Gel

Shot. This shot will be dispensed when the Idle Period

expires. The Idle Period will begin after a dispense is

completed. Any dispense operation in the middle of the

timer countdown will reset the Idle Period counter. The

system will generate an audible alarm based upon the

user Alarm setting. The alarm will sound the

user-entered number of seconds before the Idle Period

expires.

The hydraulic level sensor and hydraulic RTD for both

the pump line and mix head must be marked as enabled

when installed in the system. If the sensors are not

marked as enabled, they will be ignored by the machine

controls.

selection is critical to ensure proper operation of the

machine. When a mix head is selected, the Dispense

Valve Details button will become active. When

active, pressing this button will open a screen used to

define the mix head operating parameters. See the Mix

Head Operating Details Screen on page 62.

Selecting the dispense valve will limit the system maxi-

mum working pressure to the maximum working pres-

sure of the dispense valve. See System Screen 1 on

page 61.

Mix Head Operating Details Screen

This screen allows the user to define the mix head oper-

ating parameters.

•Low Pressure Circulation: The percentage of set-

point at which the system will run during low pres-

sure circulation.

•Pre-Dispense Circulation: The time for which the

system will circulate at high pressure prior to dis-

pensing when the dispense command is triggered

while the system is in low pressure circulation.

•Post-Dispense Circulation: The time duration that

the system will remain in high pressure circulation

after a dispense before dropping into low pressure

circulation.

•Idle Position: Applies to an L-Head only. The posi-

tion of the cleanout rod when the mix head is idle.

•Clean Out Open: Applies to an L-Head only. The

amount of time the cleanout rod will remain open

immediately after the completion of a dispense.

•Clean Out Closed: Applies to an L-Head in a Nor-

mally Open configuration only. The amount of time

the cleanout rod will remain closed when it closes

after the completion of a dispense (after the clean

out open time delay).

•Anti-Seize Delay: Applies to an L-Head in a Nor-

mally Closed configuration only. After a shot occurs

and the cleanout piston closes, the first anti-seize

delay will count down then the cleanout piston will

open and close to break loose from any curing

material. The second anti-seize timer will then begin

counting down and the cleanout piston will open and

close again to break loose from any remaining cur-

ing material. If a shot occurs before both anti-seize

timers elapse, the anti-seize timers restart.

Appendix C - ADM Run Screens Overview

Run screens are divided into five major sections: status,

errors, events, and maintenance. The following diagram

demonstrates the flow of the Run screens beginning

with the Home screen.

Home Screen

The Home screen is the first screen that displays in the

Run screens. It shows the current fluid pressure on the

A (Red) and B (Blue) fluid outlets of the pump and if

there are any active errors. If tanks are installed in the

system, the fill level is shown on each tank.

To select an operating mode, press the Select Mode

button repeatedly until the desired mode is shown

then press the Enter button to select the mode.

Alternately, press the Select Mode button and use the

up and down arrow keys until the desired mode is

shown, then press the Enter button to select the

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 let-

ter/position.

5. Press the Dispense button to begin dispensing.

Home Screen, Operator Mode

This mode allows users to set a pressure or flow rate to

dispense material without using predefined shot infor-

mation. Pressure or flow rate availability is dependent

on the Control Mode selection, see System Screen 2

on page 62.

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 dis-

pense timer.

Appendix F - USB Operation

Overview

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

• 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 lan-

guage files

• Ability to download and upload system configura-

tions

• 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

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 down-

load 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.

Download Log Files

If the “Enable Downloading of USB Logs” is checked,

the user can use a USB stick-drive 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 (DISP-

TEXT.TXT) and the system settings (SETTINGS.TXT).

The status of the download will be shown in the Status

bar.

Appendix F - USB Operation

86 3A2175A

Log Files, Folder Structure

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 down-

loaded or uploaded. In each DATAxxxx folder there is

two log files. They are formatted as .csv (comma sepa-

rated 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 trans-

ferred. Once the download is complete the SET-

TINGS.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 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 dis-

pensing. 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 pre-

vent 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.

NOTICE

The user should never attempt to modify the SET-

TINGS.TXT file in any way. Graco is not responsible

for damages caused by an improperly modified

setup file.

Update Custom Language

Use the following process to customize the text on the

ADM. The language file DISPTEXT.TXT can be modi-

fied 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 trans-

ferred. Once the download is complete the DISP-

TEXT.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

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.

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

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 dis-

pensing. 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.

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.
