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.

Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
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.

•

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.

Material Self-ignition

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

Keep Components A and B
Separate

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.

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 (resin) and component B (isocyanate)
parts.

Fluid Supply
•

Requirements

• Do not exceed the pressure rating of the lowest
rated component. See the identification label.
• To reduce the risk of injury, including fluid
injection, you must install a shutoff valve between
each fluid supply line and the mix manifold. Use
the valves to shut off fluid during maintenance
and service.

NOTE: Solvent supplied by a single source can cause
cross contamination and damage to the system. Install
check valves or use separate solvent sources.
NOTE: Paint Recirculating System Only
•

ProMix 2KE models are available to operate air spray or
air-assisted systems with a capacity of up to 3800
cc/min.
•

Fluid supply pressure tanks, feed pumps, or circulating systems can be used.

•

Materials can be transferred from their original containers or from a central paint recirculating line.

•

See manual 313599 for Coriolis meter installation
and operation instructions.

Multiple color system: connect supply lines to the
component A2 and A3 dose valve inlets (DVA2,
DVA3). See FIG. 6.

If you are recirculating paint, use the standard inlet
on Dose Valve A1 (A2, A3) or Dose Valve B.
Remove the plug directly opposite it on the dose
valve for the recirculation outlet. The second port is
on the back of the valve and must be reached from
inside the control box.
Second port

NOTE: The Coriolis meter can be used only on non-IS
systems 24F080-24F083. When installed on these systems, the meter’s hazardous location intrinsically safe
status is voided.
•

If you are using dynamic dosing, see Fluid Connections, this page. See also Set Up the Fluid Manifold for Dynamic Dosing, page 16.

NOTE: The fluid supply must be free of pressure spikes,
which are commonly caused by pump stroke changeover. If necessary, install pressure regulators or a surge
tank on the ProMix 2KE fluid inlets to reduce pulsation.
Contact your Graco distributor for additional information.

Fluid Connections
1. See FIG. 6. Connect the solvent supply line to the
1/4 npt(f) solvent valve inlets (SVA and SVB).
2. Connect the component A supply line(s).
•

Single color system: connect component supply
line to the component A1 dose valve inlet (DVA1).

ti16338a

FIG. 5. Paint Recirculation Port
•

Another option is to use a tee fitting to
recirculate.

NOTE: Verify that all unused fluid ports on the color
change valve stack are plugged before operation. An
open port will leak fluid.
3. Connect the component B line to the component B
dose valve inlet (DVB).
NOTE: The component A and B fluid meter inlets have
fluid check valves to prevent backflow from fluid supply
pressure fluctuations. Backflow can cause ratio inaccuracies.
4. Connect the gun fluid supply line between the static
mixer (SM) outlet and the gun fluid inlet.

Grounding

Feed Pumps or Pressure Pots
Connect a ground wire and clamp from a true earth
ground to the pumps or pots. See pump or pressure pot
manual.

The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical current
due to static build up or in the event of a short circuit.
Connect the ProMix 2KE ground wire to the ground
screw. Connect the clamp to a true earth ground. If wall
power is used to power controls, ground electrical connection according to local codes.

TI15712a

FIG. 11. Ground Screw and Power Switch

Gun Flush Box
Connect a ground wire from the Gun Flush Box ground
lug to a true earth ground.

Follow local code. Use only conductive metal pails/containers placed on a grounded surface. Do not place the
pail/container on a nonconductive surface, such as
paper or cardboard, which interrupts the grounding continuity.

Check Resistance

Flow Meters
Verify that the meter cables are connected as shown in
the Hazardous Location Electrical Schematic on
page 74-75. Failure to properly connect the shield may
cause incorrect signals.

To ensure proper grounding, resistance between
components and true earth ground must be less than
1 ohm.

NOTE: The Coriolis meter can be used only on non-IS
systems 24F080-24F083. When installed on these systems, the meter’s hazardous location intrinsically safe
status is voided.

FIG. 21. Flow Rate Display
If the fluid flow rate is too low: increase air pressure to component A and B fluid supplies or
increase the regulated fluid pressure of mixed
material.
If the fluid flow rate is too high: reduce the air
pressure to component A and B fluid supplies,
close the dose valves further, or decrease the regulated fluid pressure of mixed material.
4. Turn on atomizing air to the gun. Check the spray
pattern as instructed in your spray gun manual.
NOTE:
•

Pressure adjustments of each component will vary
with fluid viscosity. Start with the same fluid pressure for component A and B, then adjust as needed.

•

Do not use the first 4-5 oz. (120-150 cc) of material
as it may not be thoroughly mixed due to errors
while priming the system.
NOTICE
Do not allow a fluid supply tank to run empty. It is possible for air flow in the supply line to turn gear meters
in the same manner as fluid. This can damage the
meters and lead to the proportioning of fluid and air
that meets the ratio and tolerance settings of the
equipment. This can further result in spraying
uncatalyzed or poorly catalyzed material.

Color Change
Color Change Sequence
Step 1. Color Purge. The system flushes out the color
with solvent. The selected color change solvent valve
opens during Purge Time and closes when the time
expires.
Step 2. Catalyst Purge. The system flushes out the
catalyst with solvent. The catalyst change solvent valve
opens during Purge Time and closes when the time
expires.
Step 3. Final Purge. The system fills the line with the
selected purge media (usually solvent). The selected
purge valve opens during the Final Purge Time and
closes when the time expires.
Step 4. Catalyst Fill. The system fills the line with new
catalyst. The new catalyst valve opens during the Fill
Time and closes when the fill volume is reached.
Step 5. Color Fill. The system fills the line with new
color. The new color valve opens during the Fill Time
and closes when the fill volume is reached.
Step 6. Mixed Material Fill. The system fills the line
with mixed material. The system begins mixing components A and B until the fill volume expires.

Color Change Procedures

the gun into a grounded metal pail
until the color change sequence is
complete. If your system has two
guns, trigger both guns at the same
time.
NOTE: The color change timer does not start until
the gun is triggered and fluid flow is detected. If no
flow is detected within 2 minutes, the color change
operation aborts. The Display Module enters
Standby

mode at the previous color.

Error SG occurs if the gun flush box is open.
Error SAD1 or SAD2 occurs if the AFS is on.
5. Trigger the gun (or guns) while the system flushes
the current color, purges with solvent, and loads the
new color.
NOTE: If your system uses 2 guns, you must trigger
both guns simultaneously during the entire color purge,
solvent purge, and load color sequence.
NOTE: If you do not see clear solvent flow, the system
did not flush successfully. Stop the color change. Look
for a clog in the line or increase the flush time.
6. During color change, the Recipe icon blinks on and
off, and you’ll see the number of the current color
and the new color. When the color change is complete, Standby is highlighted.
7. When you are ready to spray, remove the gun from
the gun flush box if used, and close its door.
NOTE: The gun flush box door must be closed for
the atomizing air valve to open.

Basic Operation

Purge/Color Change Detail

Pre-Mix Fill

Purge/Flush

Premix fill sequence (right after purge sequence) loads
60 cc of the A1, A2, or A3 and B1, from the color stack,
to the mix manifold.

The Purge Sequence flushes the lines from the A & B
color stacks though the mix manifold and out to the
gun(s).
"A" has a pre-assigned (not selectable) valve. "B" has a
pre-assigned (not selectable) valve.
If you choose a third flush option, it can be "A" or "B"
(not "A" and "B"). You do not have an option to select
something other than "A" or "B" valve. For example, if
"A" was water and "B" was solvent. The third flush
options would have to be "A" water or "B" solvent. You
couldn't assign a third option like air.
The following should be the only selectable flush
sequence options:
A, B, 0

A, B, A
A, 0, B

A, B, B
0, B, 0

A, 0, A
0, B, A
0, B, B

In the premix fill sequence, a SFA1/SFA2/SFA3/SFB1
alarm (Premix fill, low flow) is generated if there are less
than 10 ccs in 60 seconds.
SHA1/SHA2/SHA3/SHB1 alarm (Not enough premix fill
volume) is generated if there are less than 50 ccs in 60
seconds.
NOTE: Premix fill always starts with the “B” side.

Mix Fill
The mix fill sequence (right after premix fill) loads A1,
A2, or A3: B1 mixed material (Ratio specified by user)
out to the gun(s). It loads 110% of the volume of the
hoses plus the volume of the manifold: (hose 1 + hose 2
+ manifold) x 1.1

There are 4 basic purge sequences as follows:

SM (mix fill low flow) is generated if there are less than
50ccs in 60 seconds during a mix fill sequence.

1. Selecting the purge button on the pendant. The
purge sequence from the recipe that you are currently in is used. The system is left full of solvent.

SN (Not enough mix fill volume) is generated if less than
the mix fill volume is loaded in 5 minutes during a mix fill
sequence.

2. Color Change from A1, A2 or A3 to A1, A2 or A3.
The purge sequence from the recipe you are leaving
is used. After the purge sequence completes, the
premix fill, from the recipe that you are going to,
starts (blinking recipe number, etc).
3. Color Change from A1, A2 or A3 to Zero. The recipe
zero purge sequence is used. The system is left full
of solvent.
4. Color change from Zero to Zero. The recipe zero
purge sequence is used. The system is left full of
solvent.
NOTE: Color Change from Zero to A1, A2 or A3. The
system does not do a purge sequence. It immediately
starts the premix fill sequence.
A SPSA/SPSB alarm (Not enough volume during purge)
is generated when the end of a purge phase is reached
(Time specified by user), and the system has not totaled
at least 10cc of material.

Dosing Options

Dosing Options
Sequential Dosing
Components A and B dispense sequentially in the necessary volumes to attain the mix ratio.
1. The operator presses

to begin operation.

2. The ProMix 2KE controller sends signals to activate
the solenoid valves. The solenoid valves activate
Dose Valves A1 (A2 or A3, depending on recipe
selection) and B. Fluid flow begins when the gun is
triggered.
3. Components A1 and B are introduced into the fluid
integrator (FI) one at a time as follows.

d. Dose Valve B (DVB) opens, and fluid flows into
the integrator and is aligned proportionately with
component A.
e. Flow Meter B (MB) monitors the fluid volume
dispensed and sends electrical pulses to the
ProMix 2KE controller.
f.

When the target volume is dispensed, Dose
Valve B closes.

4. The components are pre-mixed in the integrator,
then uniformly blended in the static mixer (SM).
NOTE: To control output from the static mixer to the
gun, install an optional fluid pressure regulator.

a. The A side dose valve (DVA1, DAV2, or DVA3)
opens, and fluid flows into the integrator.

5. Components A and B are alternately fed into the
integrator as long as the gun is triggered.

b. Flow Meter A (MA) monitors the fluid volume
dispensed and sends electrical pulses to the
ProMix 2KE controller. The controller monitors
these pulses and signals.

6. If the gun is not triggered for two minutes, the system switches to Idle mode, which closes off the mix
manifold dose valves.

When the target volume dispenses, Dose Valve
A closes.

NOTE: The dispense volume of component A and B
is based on the mix ratio and dose size set by the
user and calculated by the ProMix 2KE controller.

7. When the gun is triggered again, the ProMix 2KE
continues the process where it left off.
NOTE: Operation can be stopped at any time by
pressing

Dosing Options

Dynamic Dosing
Overview
Dynamic Dosing provides on-demand proportioning,
eliminating the need for an integrator and therefore minimizing undesired material contact. This feature is especially useful with shear-sensitive and waterborne
materials.
A restrictor injects component B into a continuous
stream of component A. The software controls the duration and frequency of each injection. See FIG. 55 for a
schematic diagram of the process.

Dynamic Dosing System Parameters
The following parameters affect dynamic dosing performance:
•

Component A Flow: Ensure that the supply pump is
sized to provide sufficient and uninterrupted flow.
Note that component A provides majority of system
flow at higher mix ratios.

•

Component B Flow: Ensure that the supply pump is
sized to provide sufficient and uninterrupted flow.

•

Component A Pressure: Ensure precise pressure
regulation. It is recommended that the component A
pressure be 5-15% lower than the component B
pressure.

•

Component B Pressure: Ensure precise pressure
regulation. It is recommended that the component B
pressure be 5-15% higher than the component A
pressure.

Select a Component B Restrictor Size
See Set Up the Fluid Manifold for Dynamic Dosing,
page 16. Use the charts on pages 66 to 70 to select an
appropriate restrictor size based on the desired flow and
mix ratio.

3A0869J

Select Dynamic Dosing
1. On the Display Module press
Home (Screen 17). Select
1 (Screen 18).
2. Select A

to access Setup
to display Configure

B from the dosing type drop down menu.

Balancing A/B Pressure
If component B pressure is too high, it will push the component A stream aside during B injection. The valve will
not open long enough, causing a Ratio High error.
If component B pressure is too low, it will not be injected
in sufficient volume. The valve will stay open too long,
causing a Ratio Low error.
Selecting the correct component B restrictor size and
balancing the A/B pressures will keep the system in the
proper pressure range, resulting in a consistent mix
ratio.
FIG. 53 shows the A to B pressure balance, read at the
proportioner inlet. It is recommended that the component B pressure be 5-15% higher than the component A
pressure to keep the system in the control range, hold
the proper mix ratio, and obtain properly mixed material.
If pressures are not balanced (“B Pressure Too High” or
“B Pressure Too Low”), it may not be possible to hold
the desired mix ratio. The system will generate an off
ratio alarm and stop operation.
NOTE: In multi-flow rate systems, it is recommended
that you set up the system to run properly at the highest
flow rate, to ensure adequate fluid supply across the
flow rate range.
In dynamic dosing, component A dose valve is constantly on. Component B dose valve will cycle on and
off; one cycle every 0.5 – 1.0 seconds indicates proper
balance.
Monitor system performance by watching the Display
Module for warning messages which provide information on system performance, and adjust pressures
accordingly. See Table 5 on page 57.

NOTE: When an error occurs be sure to determine the
error code before resetting it. If you forget which code
occurred, use Run Log Errors (Screens 5-14), page
44, to view the last 50 errors, with date and time stamps.

System alarms alert you of a problem to help prevent

Air Flow Switch (AFS) Function

Error Code Indicator

Air or Air-assisted Guns
The air flow switch (AFS) detects air flow to the gun and
signals the ProMix 2KE controller when the gun is triggered. The AFS functions with the flow meters to ensure
that system components are functioning correctly.
For example, if a flow meter fails or clogs, pure resin or
catalyst could spray indefinitely if the ProMix 2KE does
not detect the condition and intervene, which is why the
AFS is so important.

FIG. 56. Display Module Alarm Codes

If the ProMix 2KE detects through the AFS signal that
the gun is triggered, yet there is no fluid flow through the
meter, a Dose Time Alarm (QTA1 or QTB1) occurs after
40 seconds and the system shuts down.

System Advisory/Record Codes

Operating Without Air Flow Switch

Table 6 lists the advisory and record codes. Advisories
and records do not stop operation or sound an alarm. If
an advisory occurs, the Status bar on the Display Module shows the advisory icon and code. System records
do not display on the Status bar. Both advisories and
records are saved in the date/time stamped log, which
can be viewed on the display or saved to a flash drive
using optional USB port.

It is not recommended to run without an air flow switch.
If a switch fails, replace it as soon as possible.

Airless Gun
It is not recommended to use an airless gun with the
ProMix 2KE. Two issues can arise from operating without an air flow switch:
•

Without a gun trigger/air flow switch input the ProMix 2KE does not know it is spraying and will not
generate a Dose Time Alarm. This means there is
no way to detect a failed meter. You could spray
pure resin or catalyst for 2 minutes without knowing.

FIG. 57. Error Log Icons
3A0869J

System Errors

•

Since the ProMix 2KE does not know it is spraying
because there is no gun trigger/air flow switch input,
it will go into System Idle every 2 minutes when in
Mix mode.

System Idle Notice (IDLE)
This warning occurs if the ProMix 2KE is set to Mix
and 2 minutes have elapsed since the system last
received the air flow switch signal (gun trigger). The Gun
Idle icon

is displayed.

In applications using the AFS, triggering the gun clears
the warning and you can start spraying again.
Without the AFS, triggering the gun does not clear the
alarm. To start spraying again, you must press

large for the mix manifold
capacity.
QDB1
Overdose B
The B dose has overshot,
forcing an A dose that, when
combined with B, is too large
for the mix manifold capacity.

Solution
Repair the valve.
Check for pressure pulsations:
1. Close all the manifold valves.
2. Turn on the circulating pumps and
all the booth equipment (such as
fans and conveyors).
3. Check if the ProMix 2KE is reading
any fluid flow.
4. If the ProMix 2KE shows there is
fluid flow and there are no leaks
from the gun or any other seals or
fittings, the flow meters are probably being affected by pressure pulsations.
5. Close the fluid shutoff valve
between the fluid supply system
and the flow meter. The flow indication should stop.

Running a high mix ratio and a high flow
rate.

6. If necessary, install pressure regulators or a surge tank on the fluid
inlets to the ProMix 2KE to reduce
the fluid supply pressure. Contact
your Graco distributor for information.
See Ratio Low Error and Ratio High
Error, pages 61-62.
It may be necessary to restrict the flow
rate through the component B dose
valve by adjusting its hex nut.

System Errors

Alarm and Description

Cause

QTA1, QTA2, QTA3, or
QTB1
Dose Time Error
The gun trigger is active, but
no A pulses (QTA1, QTA2,
QTA3) or no B pulses (QTB1)
are detected during the dose
time selected.

System is in Mix mode and gun is only
partially triggered, allowing air but no fluid
to pass through gun.
Fluid flow rate is too low.
Flow meter or cable failed or flow meter
clogged.

Solution
Fully trigger the gun.

Increase flow rate.
To check meter sensor operation,
remove meter cap to expose sensor.
Pass a ferrous metal tool in front of the
sensor.

TI12792a

If there is a meter or cable failure, you
will see a large difference between the
amount of fluid dispensed and the flow
meter volume displayed by the Display
Module. Clean or repair meter as necessary.

valves closed.

Pressure on circulation system is fluctuating and generating meter pulses.

Replace check valve in front of meter.

Valve is leaking.

Replace valve seat, valve, or valve
seal.

Gun, manifold, or line is leaking.

Repair leak downstream of meters.

Dynamic Dosing Restrictor Selection Graphs

Dynamic Dosing Restrictor Selection Graphs
Use the graphs on pages 66- 70 as a guide to determine
the correct restrictor size for your desired flow and material viscosity. Table 6 lists the available restrictor sizes.

Table 6: Restrictor Sizes

Example:
Application: air spray system with a 5:1 mix ratio
Fluid Supply: 1:1 pumps at 100 psi (7 bar, 0.7 MPa)
Flow Rate: 300 cc/min at the gun
Select the Restrictor Size: choose either the 0.040
or 0.070 orifice, to ensure that the pressure differential is not more than 10-20 psi (0.7-1.4 bar,
0.07-0.14 MPa), provided the fluid viscosities are
similar to those tested.
•

If the viscosity of component B is lower than the viscosity of the chart used for selection you may need
to use a smaller restrictor or decrease the pressure
differential.

•

If the viscosity of component B is higher than the
viscosity of the chart used for selection you may
need to use a larger restrictor or increase the pressure differential.

•

In systems using an air-assisted gun, if the fluid
pressure of component A is higher than the component A pressure from the charts you may need to
use a larger restrictor or increase the pressure differential.
