How the PrecisionMix II 3K Works
Usage
The standard Graco PrecisionMix II 3K can blend most
two and three component epoxy or polyurethane
paints. The PrecisionMix is not for use with “quick-setting” paints (those with a pot life of less than 15 minutes). For information on handling quick-setting paints
or abrasive fluids, contact your Graco distributor.
Fluid Supply
The system can be set up to mix components supplied
from pressure tanks or feed pumps. The materials can
be transferred from their original containers or from a
central paint recirculating line.
The standard PrecisionMix II 3K is designed to operate
an air spray or air-assisted system with a capacity of
up to 2000 cc/min.
Adaptive Overrun Correction
The actual volume of fluid dispensed each cycle can
vary slightly from the calculated target. However, the
controller monitors this variance and continuously
makes adjustments to keep the ratio of Component A
to Component B and the ratio of Component C to
Component B within the user specified tolerance.
Other inputs and outputs are provided to control the
purging process, signal an alarm, and interface with
the operator. Refer to Fig. 3.21, page 3–29.
The order in which the three components are mixed
depends on the characteristics of the materials being
used. In the standard configuration, Component A is
mixed with Component C first, then the blend of A and
C is mixed with Component B. The instructions in this
manual correspond with this mixing order.
To convert the PrecisionMix II 3K to a configuration
where Component A is mixed with Component B
before Component C is added, refer to Changing the
Mixing Order, on page 2–10.
The following is a typical ratio cycle:
Figures 2.2, 2.3, and 2.4 show the flow of fluid through
component lines A, B, and C during this cycle.
1. To begin operation, the operator enters the desired
ratio and other parameters through the User
Interface (BB) and turns the operator switch (AA)
to MIX .
Operating Cycle
The 3K fluid manifold consists of four separate fluid
supply lines for Component A, B, C, and the flushing
material. The Component A, B, and C supply lines
have the following parts to individually control the flow
of the three materials. Refer to Fig. 2.2.
Fluid filters (DA, DB, DC)
Check valves (EA, EB, EC)
Flow meters (FA, FB, FC)
Dispense valves (GA, GB, GC)
The dispense valves control the entry of the components into the integrator chambers. The flow meters
monitor the exact fluid volumes being dispensed and
send electrical pulses to the controller. The controller
monitors these pulses and signals the solenoids to turn
the dispense valves on or off accordingly (based on
the target volumes calculated by the controller).
Fig. 2.1
AA BB
2. When the operator triggers the spray gun, the
controller sends a signal to activate the solenoid
valve for the component A dispense valve (GA).
See Fig. 2.2.
3. The component A dispense valve (GA) opens and
Component A begins to flow into the first integrator
chamber (L). When the correct quantity is dispensed (based on the calculated target value), the
component A dispense valve closes. See Fig. 2.2.

9. The three components continue to be alternately
fed into the integrators as long as the gun is triggered. Output from the mixer tube to the spray gun
may be controlled by a fluid pressure regulator (Q).
After the trigger is released, if the gun is not triggered again within four minutes, the system will go
to an idle mode, which closes off the mix manifold.
When the gun is triggered again, the system will
continue the process where it left off. Operation
can be stopped at any time by energizing the
standby input or shutting off the main power
switch.

Changing the Mixing Order
The order in which the three components are mixed
depends on the characteristics of the materials being
used. In the standard configuration, Component A is
mixed with Component C first, then the blend of A and
C is mixed with Component B. The instructions in this
manual correspond with this mixing order.
To convert the PrecisionMix II 3K to a configuration
where Component A is mixed with Component B
before Component C is added, perform the following
steps.

Flow Control Overview
Flow Control is used to limit the flow of material to the
air spray gun to help avoid sags and runs in the finish
due to coatings being applied too thick or quickly and
to assure adequate coverage. Flow control can be
configured for use with a manual or automatic air spray
gun. Refer to Flow Control Setup, page 8–16.
The flow control module uses flow meters, fluid regulator, current to pressure (I/P) transducer, and the PrecisionMix II 3K controller to adjust and maintain the flow
of material to the air spray gun.
Flow control is an optional feature of the PrecisionMix 3K system. Your system must be
configured with flow control hardware and
software in order to use flow control. Detailed
information on using flow control is in other
sections of this manual.
Flow control is NOT for use with air-assisted or
airless spray guns.
System Requirements
The fluid feed system must have adequate volume and
pressure to supply the air spray gun. The Component
A, B and C fluid supply pressures need to be balanced. The fluid feed hose, gun nozzle and needle
size and travel must be sized and adjusted properly to
keep the flow control operating at its maximum efficiency.
General Operation Sequence
1. When the controller is first turned on, a pre-configured pilot air pressure is applied to the fluid regulator.
2. When the air spray gun is triggered, the controller
waits for the set delay time to elapse before it
starts monitoring the flow and making any necessary adjustments. The delay time is user selectable (typically 1–2 seconds) and helps assure the
fluid is moving at a normal rate before flow rate
adjustments occur.
3. When the fluid moves through the fluid lines, the
flow meter(s) monitors the flow and sends meter
pulses to the controller. These pulses are converted into flow measurements and checked
against the set values in the controller.
Flow Control Features
Ability to control one manual or automatic air
spray gun
Programmable maximum flow setpoint
Programmable lower flow control start value for
manual gun
Delayed activation of flow control after the gun is
triggered
Manual flow rate reset function, which can be
initiated from the in-booth Flow Control Station
An indicator light on the Flow Control Station to
show when the flow rate is resetting for manual gun
operation.
4. If the fluid flow falls outside the set values, the
controller sends a signal to adjust the fluid regulator to correct the flow. The flow is raised or lowered by the pilot air pressure from the current to
pressure (I/P) transducer. The greater the pilot air
pressure to the fluid regulator, the higher the fluid
pressure and the greater the fluid flow.
5. When the air spray gun is turned off, the flow
control holds the pilot air pressure value and does
not attempt to adjust fluid flow until the gun is
triggered again.
6. When the gun is triggered, the process of controlling the fluid flow continues.

One Gun Flow Control Using a Flow Meter in the Mixed Material Line
Fig. 2.7 shows a one gun system that is using a flow meter, installed in the mixed material line, to monitor fluid flow
to the gun. Using a flow meter in the mixed material line, rather than monitoring fluid flow with the component A, B,
and C flow meters, provides a faster response to changes in the flow rate setpoint.

Flow Control Overview
Flow Control Components
(Refer to Fig. 2.7)
Flow Meter
Digital pulses are sent by the flow meters to the controller to provide fluid flow rate information.
Fluid Regulator
The flow control regulates the fluid flow to a pre-programmed flow rate by adjusting the fluid regulator. The
fluid regulator uses a pneumatic pilot pressure from a
current to pressure (I/P) transducer to open and close
the regulator needle.
Current to Pressure (I/P) Transducer
An adjustable pneumatic signal is required for the
controller to regulate the fluid flow. The current to
pressure transducer provides this signal. The controller
outputs an analog current signal that varies from 4
milli-amps to 20 milli-amps and the transducer
changes the milli-amp signal to a 1–100 psi (7–700
kPa, 0.1–7 bar) pneumatic signal. The pneumatic
pressure signal is applied to a fluid pressure regulator,
which controls the output fluid pressure to the air spray
gun.
Flow Control Station
The Flow Control Station consists of a Flow Control
Reset/Warning light and Flow Control Reset button,
which are used with manual air spray guns to manually
initiate flow control reset.
Flow Control Reset Button
Pressing the reset button will cause the flow control
system to calibrate the flow rate to the current setpoint.
Flow Control Reset/Warning Light
The controller activates the Reset/Warning light when
the flow control system is resetting flow rate (solid
light) or when a flow control alarm condition occurs
(flashing light––flow rate is outside the set tolerance).
Flow Rate Alarms
Wait for the system to automatically calibrate the flow
rate or manually reset the flow rate by pressing the
reset button.
Flow Control Reset/
Warning Light
PrecisionMix II 3K Controller
The controller can be configured to control and display
the fluid control information, including setpoint, actual
flow, milli-amp output values to the I/P transducer,
system parameter, and I/O conditions. The controller
will indicate when the system is operating within flow
control tolerance and when it is not.

Overview
Flow Control Overview
Flow Control Parameters (Refer to Fig. 2.9)
The following flow control parameters are entered from
either the User Interface or from digital input:
Setpoint Source – Specifies the source of the
flow limit value as User Interface, network or analog
input (refer to page 8–18).
Analog Scaling – If analog is the source of input,
the scaling for analog input must be set. The setting
is used to calculate the relationship between the
flow rate and a 4–20 mA input signal (refer to page
8–18).
Flow Rate Setpoint – Sets the value for the
desired flow rate. Flow control monitors and calibrates flow rate based on this value and the other
parameters (refer to page 9–9 or 9–16).
Delay Time – Sets the time that flow control waits
after the gun is triggered before starting to monitor
the flow rate. This allows time for the fluid to quickly
reach the setpoint and avoid unnecessary alarms or
corrections (refer to page 8–19).
Flow Control Low Limit – This value is only used
with manual guns and is always entered from the
User Interface (refer to page 9–9). The flow control
stops making adjustment if the flow rate falls below
the difference of setpoint and the “Low Limit”
volume. The warning alarm output will be on when
the actual flow rate falls out of this tolerance for 5
seconds. This helps the system allow for periodic
partial triggering (feathering) of a hand gun without
adjusting the flow rate.
If the setpoint is changed, the low limit will change
accordingly.
Example – If the setpoint is 500 cc/min. and the low
limit is 100 cc/min.:
The flow control will stop making adjustments
when the flow rate falls below 400 cc/min.
Changing the setpoint to 300 cc/min. will

Using Recipes/Color Change
There are three modes of operation relating to the
changing of recipes: No Color Change, Integrated
Color Change, and Integrated Color Change with
Queue. Refer to page 8–22. The controller logic
decides whether or not to allow a chosen recipe
change to occur. The criteria for allowing a recipe
change are as follows:
1. The new recipe must contain valid data for the
desired ratio, flow meter K-factors, tolerance, and
pot life times.
2. An active alarm must not exist in the system.
3. An Integrated Color Change can not already be in
progress.
4. The recipe number must not be greater than the
number of recipes configured to run on the system.
5. The input device used to change the recipe value
must be configured as the recipe input device
(User Interface, Network, I/O, or Operator Station).
6. When “No Color Change” is selected, the operator
switch on the Operator Station must be in the
A color change may be performed with the operator
switch in the Mix or Standby position. If the
operator switch is in the Mix position, the system
will be ready for immediate spraying after a color
change. The green light on the Operator Station will
blink while a color change is in operation. The green
light indicates that the system is busy and is not ready
for spraying.
Mix/Load Volumes
If mix/load volumes are configured for the system, the
fill portion of the color change may continue after the
color change has timed out. This feature may be used
in conjunction with a gun flush box to make sure that
the desired volume of material is loaded into the system. The system keeps track of the volume that is
mixed during the fill portion of the color change. If the
mix/load volume is not reached, then the system will
continue to fill until the volume is reached (the operator
switch needs to be in the Mix position for this to
occur automatically). Setting the mix/load volume to
zero will disable the mix/load volume feature.
Standby
position.
No Color Change
The system will boot up for the first time with color
change turned off. In this mode, color changes are
performed manually. The recipe number is changed
through the User Interface, Network, I/O, or Operator
Station. The operator must manually dump and purge
the old material from the system and then load the new
material into the system.
Integrated Color Change
The Integrated Color Change mode of operation
automatically performs the tasks necessary to execute
a color change. This is a time-based mode that is
configurable by the user. Refer to page 8–21. The
timing of the color change is configured in one of four
color change sequences. The color change
sequences contain start times and timer duration for
the devices that are controlled during a color change.
Each recipe is then assigned one of the four color
change sequences for its operation.
Recipe Zero
Recipe zero is considered the “Purge Down” recipe.
The purpose of this recipe is to allow the user to purge
out the material lines and the mixed material lines
without loading a new color. A typical use for recipe
zero is at the end of a shift. The operator performs a
color change to recipe zero and the lines are cleaned
out to prevent hardening of catalyzed material between
shifts. Multiple Purge Downs may also be performed if
the lines are not sufficiently clean. Another Purge
Down is triggered by pressing the Enter key on the
Operator Station or by setting the the color change bit
on the I/O high.
NOTE: Recipe 0 has a unique Purge Sequence 0 to
allow for end of shift or production shutdown. If you are
using a solvent meter, any additional solvent used in
the recipe 0 purge cycle will not be included in the
solvent totals. It is important to configure Purge Sequence 0 to flush all materials clean in one purge
cycle, to maintain accurate solvent use records.
Continued on the next page.

Overview
Using Recipes/Color Change
Integrated Color Change – continued
The devices that are controlled by the Integrated Color
Change Sequences are as follows.
Purge Valves: The Integrated Color Change
Sequence typically starts by purging out the old mixed
material. The purge can be further defined by setting
the total purge time, the purge time for the first cycle,
the purge time for the last cycle, and the individual
purge times for the three possible purge valves. The
beginning of the purge can be delayed to allow time for
the gun triggers to activate. Refer to page 8–23.
Mix Valves: The sequence fills the hoses with the new
mixed material after the system has finished purging.
The target mix parameters are calculated after the
purge is completed, before the mix begins. The user
defines the mix (fill) time duration for the Color Change
Sequence. Refer to page 8–23.
Dump Valves: The dump valves open immediately
when the Color Change Sequence begins. The user
then configures how long these valves stay open. The
purpose of these valves is to allow the unmixed A, B,
and C component materials to dump from the system
before entering the mix manifold. Refer to page 8–24
and 8–26.
Special Outputs 1, 2, 5, and 6: The special outputs
are optional outputs that the user can configure for
their particular application. Each of these valves can
be turned on and off up to four times during a color
change sequence. Refer to page 8–28.
Specials 1 and 2 are pneumatic outputs, while Specials 5 and 6 are electrical outputs.
Integrated Color Change with Queue
The Integrated Color Change with Queue mode of
operation runs in a similar fashion to the standard
Integrated Color Change mode. The difference
between the two modes is that the Queue parameters
override the normal color change parameters during
the color change. Five data sets can be set up in a
queue and sent to the controller individually. Refer to
page 6–7. A queue data set consists of the following
five parameters.
1. Sequence Number – The number for the color
change sequence that will be used for the new
color.
2. Recipe Number – The recipe number that will be
used for the new color.
3. Color Valve Component A (Resin) – The number
corresponding to the component A color valve
chosen for the new color.
Solvent Valves: The Solvent valves open immediately
when the Color Change Sequence begins. The user
then configures how long these valves stay open. The
purpose of these valves is to push the unmixed A, B,
and C component materials through the dump valves
and clean the hoses for the next material. Refer to
page 8–24 and 8–26.
Gun Triggers 1–2: The gun triggers are electrical
outputs that can be configured to turn on and off up to
two times. These outputs are typically wired to the
spray guns triggers to allow automatic purging and
filling. Refer to page 8–27.
4. Color Valve Component B (Catalyst) – The
number corresponding to the component B color
valve chosen for the new color.
5. Color Valve Component C (Reducer) – The
number corresponding to the component C color
valve chosen for the new color.
A Queue Color Change is triggered by pressing the
Enter key on the Operator Station or by setting the
Color Change Bit on the I/O of the controller. The data
set values on the top of the queue will be used for the
Color Change. When color change is complete, the
top level of the queue is erased and all of the other
data sets move up one level on the queue.

Using Recipes/Color Change
Color Change Sequences
There are four color change sequences that can be set
up to control how a color change will operate. These
sequences can be viewed on the User Interface in a
graphical fashion. A typical color change sequence
looks as follows.

Sequence 1:
Purge time = 20 Seconds
Mix time = 20 seconds
Component A Dump time = 7 seconds
Component A Solvent time = 5 seconds
Gun 1 time = 40 seconds
Total Sequence Time = 40 seconds
The color change sequence begins by closing all of the
color change valves. Then the dump valve for Component A (resin) will immediately open, as well as the
solvent valve on the color stack. This will allow solvent
to flow into the fluid lines, through the flow meter, and
out through the dump valve.
The color change solvent valve stays open for 5 seconds, then it closes and the new color valve, associated with the new recipe, will open. The dump valve
remains open for two seconds after the new color
valve is opened, to allow the new color to fill the fluid
line and flush out the remaining solvent. The dump
valve is open for a total of 7 seconds.
In parallel with the dumping and filling of the fluid lines,
a purge is occurring through the mix manifold and
mixed material lines. The purge always starts at the
beginning of a color change sequence. The above
sequence triggers Gun 1 for the entire sequence. This
allows the purge to flush solvent through the mix
manifold and mixed material lines and out through the
gun. After 20 seconds, the purge is complete.
The system then begins to mix new material. The
system mixes for 20 seconds until the mix manifold
and the mixed material lines are full of new material.
This sequence is a 40 second long operation.
NOTE: When using automatic spray guns or gun flush
boxes, you must specify trigger times for each gun.
The screen shown above reflects the use of manually
triggered spray guns.

Overview
Using Recipes/Color Change
Changing from One Color Change
Sequence to Another
It is possible to perform a color change from a recipe
associated with one color change sequence to a recipe
that is associated with another color change sequence.
In this case the system automatically uses the old
sequence for dumping and purging and the new
sequence for loading and mixing. This type of color
change is useful in applications where one material
tends to purge and load more quickly than another.
When switching from one sequence to another, there
are two transition points that determine which
sequence is being used at a given time. The first
transition point occurs when the solvent valve for the
color change stack closes. The second transition point
is when the purge is complete. The table at right lists
the outputs associated with the transition points.
An example of a color change from one sequence to another is as follows.

Fluid Supply Requirements
Common fluid supplies include pressure tanks, circulating lines, and pail or drum pumps. The fluid supply
should be capable of supplying enough pressure to
deliver a flow rate 1.5 times the maximum desired flow
rate.
If the Flow Control system is installed, it is very important to balance the fluid pressures of the Component
A, B and C fluid supplies to be within 2 psi (14 kPa, 0.1
bar) of each other at the fluid outlet.
The fluid supply must be free of pressure spikes, which
are commonly caused by a pump stroke changeover.
If necessary, install pressure regulators on the fluid
inlets to the PrecisionMix II 3K to reduce the fluid
supply pressure. Contact your Graco distributor for
information on fluid pressure regulators.
Circulating Lines
For maintenance and safety, you must install a ball
valve between each supply line and the
PrecisionMix 3K.

Ground the System
See Fig. 3.22.
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
To reduce the risk of fire, explosion, or
electric shock:
The PrecisionMix II 3K system must
be electrically connected to a true
earth ground; the ground in the electrical system is not sufficient.
All wires used for grounding must be
10 gauge minimum.
A qualified electrician must complete all ground-
ing and wiring connections and check the
resistance as instructed on page 3–31.
Refer to your local code for the requirements for
a “true earth ground” in your area.
Also read and follow the warnings on page 1–3.
Ground the PrecisionMix II 3K system as instructed
here and in the individual component manuals. A
ground wire and clamp, part no. 222–011, is available
from Graco. Grounding instructions are continued on
page 3–31.
Controller
Connect the controller’s green-yellow ground terminal
block to the NEMA enclosure’s grounding lug. Connect
a ground wire from the enclosure to a true earth
ground. The controller enclosure and the manifold
mounting surface must be connected to the same true
earth ground point.
PrecisionMix II 3K Manifold
The mounting surface for the PrecisionMix II 3K manifold must be electrically connected to the same true
earth ground point as the controller enclosure. Different ground points may cause current to flow through
the meter cables, causing incorrect signals.
Color Change Panel
The mounting surface for the color change valves and
solenoids must be electrically connected to the same
true earth ground point as the controller enclosure.
Different ground points may cause current to flow
through the network cables, causing incorrect signals.
Operator Station
Ground the operator station to a true earth ground.
Flow Control Station
Ground the flow control stations to a true earth ground.
Gun Flush Boxes
Ground the gun flush boxes to a true earth ground.
Gun Flush Solenoid Boxes
Ground the gun flush solenoid boxes to a true earth
ground, or mount them on a grounded surface.
Flow Meters
Connect the meter cables as instructed in the manual
for your flow meter. Failure to properly connect the
grounded conductor and shield may cause incorrect
signals.
Feed Pumps or Pressure Pots
Use a ground wire and clamp to electrically connect
the pumps or pots to a true earth ground. See your
separate pump or pressure pot manual.
Air and Fluid Hoses:
Use grounded hoses only.
Spray Gun
Follow the spray gun manufacturer’s grounding
instructions.
Fluid Supply Container
Ground the container according to your local code.
Object Being Sprayed
Ground the object according to your local code.
All Solvent Pails Used When Purging
Ground the solvent pails according to your local code.
Use only metal pails, which are conductive, placed on
a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which
interrupts the grounding continuity.
Maintain Grounding Continuity When Purging Or
Relieving Pressure
Follow the instructions in your separate gun manual for
safely grounding your gun while purging.

WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
To reduce the risk of fire, explosion, or
electric shock the resistance between
the PrecisionMix II 3K components and
true earth ground must be less than 1
ohm.
TI0163
Have a qualified electrician check the resistance
between each PrecisionMix II 3K component and the
true earth ground. The resistance must be less than 1
ohm. If the resistance is greater than 1 ohm, a different
ground site may be required. Do not operate the
system until the problem is corrected.

Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
install or clean the spray tip.
1. Set the operator switch to STANDBY .
2. Relieve fluid and air pressure at the component
and solvent feed pumps or pressure pots, as
explained in their separate instruction manuals.
3. Set the operator switch to MIX .
4. If using an electrostatic gun, make sure the electrostatic power is turned off.
5. Hold a metal part of the spray gun firmly to the
side of a grounded metal pail, and trigger the gun
to relieve fluid pressure.
6. Set the operator switch to STANDBY .
Stop production at any time by setting the operator
switch to STANDBY. If your stop time will not exceed
the pot life of Component A, B, or C, no additional
action is needed, except to relieve the system pressure. If your stop time will exceed the pot life, you must
purge the mixing system.

Operation
Purging the PrecisionMix II 3K System
WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of fire, explosion and
serious injury when purging the PrecisionMix II 3K:
Be sure the entire system and flush-
ing pails are properly grounded.
Follow the instructions in your separate gun
manual for safely grounding your gun while
purging.
WARNING
INJECTION HAZARD
To reduce the risk of a serious injury
from injection or splashing fluid:
Follow the Pressure Relief Proce-
dure on page 4–3 whenever you
are instructed to relieve the pressure.
If you are using a high pressure gun*, remove
the spray tip before purging. Relieve pressure
before removing the spray tip.
Wear protective eyewear.
Use the lowest possible fluid pressure when
purging.
Purge the system during initial startup, at the end of
each workday, and before any break longer than the
pot life of the fluid.
Solvent may be used to purge all three components,
but this will result in longer purge sequences and high
solvent usage. Call your Graco distributor before
choosing this option.
Recipe Zero
If you are using integrated color change, you
can use Recipe 0 to also purge the color
change stacks. Refer to page 9–4.
Recipe zero is considered the “Purge Down”
recipe. The purpose of this recipe is to allow
the user to purge out the material lines and the
mixed material lines without loading a new
color.
A typical use for recipe zero is at the end of a
shift. The operator performs a color change to
recipe zero and the lines are cleaned out to
prevent hardening of catalyzed material
between shifts.
Multiple Purge Downs may also be performed if
the lines are not sufficiently clean. Another
Purge Down is triggered by pressing the Enter
key on the Operator Station or by setting the
the color change bit on the I/O high.

e. Set the operator switch to Mix to spray.
9. Adjust the flow rate.
If a flow control system is installed, see page 8–16
for flow control setup instructions and page 4–15
for flow control operation.
b. Check the air pressure regulators on the fluid
supply tanks. The fluid flow rate at the spray
gun should be the same regardless of whether
the Component A, B, or C dispense valves are
open. The pressure adjustments of each
component will vary with each components
viscosity.
c. Check or reset the air regulator in the atomiz-
ing air line.
10. Operation of the PrecisionMix II 3K is controlled by
the operation of the spray gun. When the gun is
triggered and the Operator Station switch is set to
Mix , the dispense valves cycle and allow
Components A, B, and C to enter the mix manifold
and be mixed and dispensed to the gun.
NOTES:
If required, switch on the supply tank agitators
briefly whenever the fluid needs stirring. Over-agitating can cause air entrainment.
Periodically check the fluid level in the fluid supply
tanks.
For a system without flow control:
a. If the fluid output is too low, increase the
regulated fluid pressure. If the fluid output is
too high, adjust the fluid pressure regulator.
For fine adjustment, close the dispense valves
further.
Operation 4–13
Never allow the fluid supply tanks to empty completely while the PrecisionMix II 3K is operating. Fill
them periodically, as needed. Failure to fill the tanks
when they are low may cause the metering ratios to
be incorrect without an alarm occurring.

initial flow rate reading after the gun is triggered.
Flow Control Tips
Always keep a balanced fluid inlet pressure be-
tween component A, component B, and component
C. This will prevent the fluid pressure regulator from
opening or closing every time the PrecisionMix
system switched from A valve to B valve to C valve.
Do this by adding a manual fluid regulator for each
of the fluid supply inlet. Also, try to adjust the
dispense valve opening. Refer to the Plural Component Mix Manifold manual 308288.
Keep the gun trigger on as long as possible during
spraying. This will give the PrecisionMix system
more time to adjust the fluid regulator to get to the
flow rate setpoint. If the gun delay time is set at 1.0
second, and the gun trigger is on for 2.0 seconds,
then the PrecisionMix system has only one second
to do any flow control.
Add an inline flow meter with high–resolution pulse
output in the mixed material stream. Note that any
flow meter installed in the mixed material stream
may experience a flushing/clearing problem.

WARNING
INJECTION HAZARD
To reduce the risk of a serious injury,
follow the Pressure Relief Procedure
on page 4–3 whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
install or clean the spray tip.
1. If using an electrostatic gun, turn off the electrostatics.
WARNING
FIRE AND EXPLOSION HAZARD
For Electrostatic Guns: To reduce the
risk of fire, explosion, or electric shock,
always turn off the electrostatics on an
electrostatic gun before placing the gun
in the Gun Flush Box.
Multiple Gun Flush Box Operation
NOTE:
Guns will be loaded and purged in sequential order.
The sequence depends on which guns are in their
box at the start of a fill cycle.
During the automatic purge cycle, only guns with
mixed material loaded will be purged.
Automatic purge will not start until all guns with
loaded material are in their box. Operators should
put the guns in their box with the door closed
whenever they finish spraying.
If a gun or guns are being taken out of the line for
service (by valve shutoff or other means), one of
the following things must occur to prevent the gun
flush box controller from trying to fill these guns
during the mix/fill mode.
Leave the gun in the box, but leave the door
partially open or
Take the gun out of the box completely.
2. Place the gun in the Gun Flush Box and close the
door.
3. Set the Operator Station switch to Standby or
Mix .
4. Select the new Recipe.
5. When the color change indicator light stops flashing or the color change popup screen stops displaying on the User Interface, the color change is
complete.
6. When ready to spray, remove the gun from the
Gun Flush Box and close its door.
NOTE: The Gun Flush Box door must be closed for
the atomizing air valve to open.
7. Set the Operator Station switch Mix to start
spraying.
NOTE: The first three PrecisionMix II 3K alarms will be
reset by the controller to prevent nuisance alarms
during flushing and loading.
Purge the gun(s) before taking them out of the
line for service.

System Idle Time Remaining: 00 min
Flow rate is a real time display of how much flow is
going through the system. It updates every two
seconds and is a weighted average of the previous
flow rate displays. The readings are taken by the
Component A, B, and C fluid meters. The flow rate
display can be altered in the setup program to read in
ounces per minute. See page 8–6.
Potlife Time Remaining
Potlife time remaining displays the time remaining
before a potlife alarm will occur. The timer does not
start until the controller detects mixed material is in the
lines.
System Idle Time Remaining
System Idle Time uses a 4 minute clock that counts
down the time that the spray device is not in use. After
4 minutes of not triggering the spray device, the mix
manifold closes and the screen changes to the System
Idle screen. When the spray device is triggered with
the operator switch set to mix, the PrecisionMix will
start again where it left off.
The potlife timer values will appear for the
