Grounding  
Pump shaft, polyethylene (PE) tank lid, and PE tank lid  
gasket are coated with Krytox grease. Wear protective  
gloves and cover exposed skin to avoid possible skin  
irritation on contact. Read Krytox MSDS to know the  
specific hazards, and follow manufacturer’s warnings.  
The equipment must be grounded to reduce the risk of  
static sparking and electric shock. Electric or static  
sparking can cause fumes to ignite or explode.  
Improper grounding can cause electric shock.  
Grounding provides an escape wire for the electric  
current.  
Locate Machine  
1. Locate a bench top or open floor area to mechani-  
cally mount the machine. Ensure the location has  
access to compressed air and AC power and is well  
ventilated.  
General Grounding Guidelines  
Pump: use ground wire and clamp (P). Refer to page 6  
for component identification. Connect ground wire and  
clamp to a true earth ground.  
2. Place the machine on the designated location. Allow  
the machine to rest on the rubber feet provided.  
Mount Machine, if Needed  
Fluid hoses: use only electrically conductive hoses.  
3. Remove the shield locking screws on both sides,  
then remove the protective shield.  
Dispense Valve: ground through a proper connection to  
a fluid hose and grounded pump.  
4. Attach the frame to the selected location by install-  
ing fasteners (not provided with unit) through the  
two mounting holes. See FIG. 3.  
Fluid supply container: follow local codes.  
Object being sprayed: follow local codes.  
10 in.  
(254 mm)  
Solvent pails used when flushing: follow local code.  
Use only conductive metal pails, placed on a grounded  
surface. Do not place the pail on a nonconductive sur-  
face, such as paper or cardboard, which interrupts  
grounding continuity.

8. Install an air inlet bleeding ball valve and air filter kit  
(not provided with unit, but available as kit 24R707)  
at the 1/4 NPT female air inlet.  
NOTICE  
The system must have a bleed-type ball valve that  
bleeds pressure downstream when closed. Other-  
wise, the supplied air will need to be disconnected  
from the system whenever the pressure is relieved.  
NOTE: The system must use an air filter with a minimum  
flow rate of 30 scfm.  
9. Close the ball valve.  
NOTE: Air supply pressure must be between 80 psi (550  
kPa, 5.5 bar) and 100 psi (690 kPa, 6.9 bar). Recom-  
mended pressure is 100 psi (690 kPa, 6.9 bar).  
Ground System  
The equipment must be grounded to reduce the risk of  
static sparking. Static sparking can cause fumes to  
ignite or explode. Grounding provides an escape wire  
for the electric current.

positive.  
When the machine executes a shot, materials from  
Tank A and Tank B enter the static mixer where they are  
mixed and then dispensed. In order for the materials to  
mix at the desired ratio, both materials must enter the  
static mixer at the same time. The timing of the materials  
entering the static mixer is dependent on the adjustment  
of the phase adjustment screw for each piston.

Setup  
Adjust Dispense Valve Snuff  
Back  
At the end of a shot, a small amount of material is drawn  
back into the static mixer to prevent extra material from  
being dispensed. If too much snuff back occurs, air will  
enter the static mixer and can travel up into the dispense  
valve. If too little snuff back occurs, the materials may  
drip out of the static mixer and affect dispense quantity.  
It is most efficient to adjust the snuff back while material  
is dispensing, but it can also be adjusted when there is  
no air pressure in the system.  
1. Navigate to the Shot Mode Screen or Operator  
2. Select a small size shot.  
3. If a static mixer is not in place, install one, then  
prime the machine. See Prime the Dispense Head,  
page 28.  
4. Place a waste container under static mixer.  
5. Press the Dispense Request button (  
).  
6. Inspect the tip of the static mixer for dripping mate-  
rial or for air bubbles traveling up the mixer.  
7. Perform another shot and, while dispensing, adjust  
the snuff-back adjustment knob as follows.  
If an air bubble is moving up the mixer, turn the  
knob clockwise to decrease snuff back.  
If material is hanging from the tip of the mixer,  
turn the knob counterclockwise to increase  
snuff back.  
8. Repeat step 7 until snuff back is adjusted as  
desired.

Setup  
If a high positive number is entered for ODV timing, such  
as 6.0 mm, the dispense valve may not open resulting in  
the fluid stalling against the dispense valve. The fluid in  
the hose lines will remain under pressure until the piston  
is manually retracted using the Manual screen, see  
Adjust Open Dispense  
Valve (ODV) Timing  
When a shot is performed, the dispense valve needs to  
open at a precise time for material to be dispensed  
properly. If the dispense valve opens too early, material  
may drain from the static mixer before the shot starts. If  
the dispense valve opens too late, pressure may build in  
the machine before the dispense valve opens, causing  
material to forcefully spray out of the mixer.  
The Open Dispense Valve Timing should also be  
adjusted for material viscosity. Thicker materials should  
have the dispense valve open earlier and thinner materi-  
als should have the dispense valve open later.  
FIG. 8: Open Dispense Valve Position Calibration  
A positive value for Open Dispense Valve Timing indi-  
cates the dispense valve will open after the piston is  
engaged in the cylinder. A negative value indicates the  
dispense valve will open before the piston is engaged in  
the cylinder.  
2. Press the Dispense Valve Open Position Adjust but-

Splash Screen  
Operator Mode Screen  
This screen is activated during a boot up condition. The  
splash screen will only be present approximately for five  
seconds.  
This mode is the dispensing mode where the dispense  
amount is dictated by the duration the user is requesting  
the dispense. To dispense in this mode, the user can  
either press and hold the dispense key, or press and  
hold an optional footswitch. If the user releases the  
footswitch or dispense key, the dispense operation will  
terminate, and the pump will return to the retract  
position unconditionally.  
Disable Mode Screen  
Mode Selection Programming Screen  
When the system is in this mode, all outputs are dis-  
abled. This mode is activated in the bootup situation, or  
if the user presses the System Shut-Down Key. To exit  
this mode, the user simply needs to press the Power On  
icon softkey.  
This programming mode is entered by pressing the  
mode select designation soft key option, from any of the  
three possible run mode screens. When activated, the  
user can select between Shot, Manual and Maintenance  
modes. The highlighted graphics in the top left portion of  
the display will indicate the current selection.  
Shot Mode Screen  
This mode is the dispensing mode where the user can  
define a shot amount by defining the percentage of  
stroke for the dispense operation. When dispensing in  
this mode, the machine will produce the same amount of  
material for each dispense. To dispense out of this  
mode, the user needs to momentarily press the dis-  
pense key, or press an optional footswitch.

Maintenance Mode Run Screen  
Error Code Acknowledgement Screen  
Used for machine testing. The user will be able to  
extend or retract the pump, or open and close the dis-  
pense valve from this screen. Once the user has navi-  
gated to function to be implemented, the user simply  
needs to press the dispense request key to issue the  
request.  
This screen will be generated if an error condition  
becomes active. The screen will contain the code for  
the condition, a graphic describing the condition, the  
standard Graco alarm bell, and a soft key prompting the  
user to acknowledge the condition. Once the condition  
has been acknowledged by the user, the screen will  
return to the main run screen. If the condition is still  
present after acknowledgement, the code previously  
presented to the user will be displayed on the bottom left  
hand corner of the main run screen. Once the condition  
is corrected, the code displayed will be removed.  
Shot Amount or Stroke % Adjust Screen  
If in shot mode, and the user has enabled this run  
screen adjustment (via a setup screen option), the user  
can adjust the shot amount by simply pressing the Up or  
Down arrow keys, then pressing the accept user entry  
softkey. The minimum percent required is 15 percent.  
Run Screen while Dispensing  
Additional information is provided during a dispense  
operation, consisting of a progress bar representing the  
current % complete of the dispense operation (shot  
mode only), and the amount of time elapsed for a dis-  
pense. During a dispense, the run screen programming  
options are no longer available. Once the dispense is  
completed, the screen will return to the main home run  
screen.

Screen  
If a password is programmed into the LCM, the user will  
be prompted to enter a password. If no password has  
been entered (all 0's on the password set/ clear setup  
screen), this screen will be bypassed.  
This screen is to set or view the position with reference  
to the metering tube entrance where the dispense valve  
is opened during the forward stoke of the pump.  
Position Calibration Screen  
Dispense Amount Prohibit and View Cycle  
Counter Screen  
This screens is used to set or observe the proper posi-  
tions on the linear position sensor for full extend, retract  
and entrance into the metering tube. All valid entries  
must be present for the machine to operate. The extend  
position must be greater than the metering tube posi-  
tion, which must be greater than the retract position.  
When the position is accepted, the real time position  
sensor reading in the middle of the screen will be trans-  
ferred to above the graphic for the corresponding posi-  
tion. The process needs repeated for all three  
positions.  
This screen will enable the user to lock out or enable the  
operator to change stroke percentage for the shot mode  
run screen. The user will also be able to view the  
machine cycle counter.  
Setup Screen Password Set/Clear Screen  
Phasing Shot Calibration Screen  
This screen will allow the user to view, set or clear (by  
entering four 0's) the password. Setting a new password  
or clearing the password feature is identical to the  
method used to enter the setup screen, if a non-zero  
password is present.  
This screen is to instigate a phasing shot, and to define  
the percentage of stroke for a phasing shot.
