Important Two-Component Material Information

Important Two-Component Material Information
Isocyanate Conditions

Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and
atomized particulates.
Read material manufacturer’s warnings and material MSDS to know specific hazards and precautions
related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufficient ventilation in the work area. If sufficient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate
personal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.

Material Self-ignition

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

Keep Components A and B
Separate

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.

Changing Materials
•

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

•

Always clean the fluid inlet strainers after flushing.

•

Check with your material manufacturer for chemical
compatibility.

•

Most materials use ISO on the A side, but some use
ISO on the B side.

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 (isocyanate) and component B (resin)
parts.

2. The operator presses the Mix
operation.

key to begin

3. The ProMix 2KS controller sends signals to activate
the solenoid valves. The solenoid valves activate
Dose Valves A and B. Fluid flow begins when the
gun is triggered.
4. Components A and B are introduced into the fluid
integrator (FI) one at a time as follows.
a. Dose Valve A (DVA) opens, and fluid flows into
the integrator.
b. Flow Meter A (MA) monitors the fluid volume
dispensed and sends electrical pulses to the
ProMix 2KS controller. The controller monitors
these pulses and signals.

In typical operation (ratios 1:1 and above), component A
dispenses constantly. Component B dispenses intermittently in the necessary volume to attain the mix ratio.

Recipe (Color) Change

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 2KS controller.

Solvent Push
The Solvent Push feature enables the user to save
some mixed material by pushing it out to the gun with
solvent. The feature requires an accessory solvent

When the target volume dispenses, Dose Valve
A closes.

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 2KS controller.

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

The Mix Fill Push feature enables the user to prevent
potlife expiration of material by mixing and flowing new
material through the Gun Flush Box. See page 64 for
complete information.

System Operation

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

5. 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.

8. When the gun is triggered again, the ProMix 2KS
continues the process where it left off.

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

NOTE: Operation can be stopped at any time by
pressing the Standby

General Operating Cycle, Dynamic Dosing
Overview

Dynamic Dosing System Parameters

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.

The following parameters affect dynamic dosing performance:

A restrictor injects component B into a continuous
stream of component A. The software controls the duration and frequency of each injection. See FIG. 52 for a
schematic diagram of the process.

•

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.

NOTE: When using dynamic dosing it is very important
to maintain a constant, well-regulated fluid supply. To
obtain proper pressure control and minimize pump pulsation, install a fluid regulator on the A and B supply
lines upstream of the meters. In systems with color
change, install the regulator downstream of the
color/catalyst valve stack.

ratio.

NOTE: Do not use the material mixed when in DD setup

System Operation

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 High Ratio alarm.
If component B pressure is too low, it will not be injected
in sufficient volume. The valve will stay open too long,
causing a Low Ratio alarm.
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. 57 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 EasyKey
display for warning messages which provide information
on system performance, and adjust pressures accordingly. See Table 6 on page 51.

System Operation

Air Flow Switch (AFS) Function

Operating Without Air Flow Switch

Air or Air-assisted Guns

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

The air flow switch (AFS) detects air flow to the gun and
signals the ProMix 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 does not
detect the condition and intervene, which is why the
AFS is so important.
If the ProMix detects through the AFS signal that the
gun is triggered, yet there is no fluid flow through the
meter, a Dose Time Alarm (E-7 or E-8) occurs after 40
seconds and the system shuts down.

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

Without a gun trigger/air flow switch input the ProMix 2KS does not know it is spraying and will not
generate a Dose Time Alarm (E-7 or E-8). This
means there is no way to detect a failed meter. You
could spray pure resin or catalyst for 2 minutes without knowing.

•

Since the ProMix 2KS does not know it is spraying
because there is no gun trigger/air flow switch input,
it will go into System Idle (E-15) every 2 minutes
when in Mix mode.

System Idle Warning (E-15)
AFS
TI13350a

FIG. 60: Air Flow Switches

This warning occurs if the ProMix is set to Mix
,
and 2 minutes have elapsed since the system received
a flow meter pulse.
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 Standby
, then Mix

, then trigger the gun.

as needed for your application. Use lowest pressure possible.
7. Do not exceed the maximum rated working pressure shown on the system identification
label or the lowest rated component in the system.
8. Open the fluid supply valves to the
system.
9. Adjust the air pressure. Most applications require about 80 psi (552
kPa, 5.5 bar) air pressure to operate properly. Do
not use less than 75 psi (517 kPa, 5.2 bar).
10. If using a gun flush box, place the gun into the box

key on the

Watch the fluid flow rate displayed on the Status
screen while the gun is fully open. Verify that the
flow rate of components A and B are within 10% of
each other.
If the fluid flow rate is too low: increase air pressure to component A and B fluid supplies or
increase the regulated fluid pressure.
If the fluid flow rate is too high: reduce the air
pressure, close the fluid manifold dose valves further, or adjust the fluid pressure regulator.
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.
NOTE: Do not use the first 4-5 oz. (120-150 cc) of material as it may not be thoroughly mixed due to alarms
while priming the system.
12. Turn on atomizing air to the gun. Check the spray
pattern as instructed in your spray gun manual.
NOTE: 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 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.

11. Adjust the flow rate.
The fluid flow rate shown on the EasyKey Status
screen is for either component A or B, depending on
which dose valve is open. The fluid supply lines on
the screen highlight to show which dose valve is

Mix Fill Push Feature
The Mix Fill Push feature enables the user to prevent
potlife expiration of material by mixing and flowing new
material through the Gun Flush Box.

1. The system gets a Potlife alarm.
2. The buzzer will do a double "chirp" every 4 seconds
to indicate an impending Mix Fill Push.

Mix Fill Push requires an accessory Gun Flush Box for
each gun that will use this feature. Order Graco Part No.
15V826 Fun Flush Box Kit. See manual 312784.

3. After waiting for the 2-minute Auto Dump time the
system will run the Mix Fill Push.

NOTE: If the gun is not in the box the Mix Fill Push feature will not operate.

NOTE: On a one-gun system the gun must be in the
GFB. On a 2-gun system both guns must be in the
GFBs.

NOTE: The Mix Fill Push operation will run every time
the Potlife alarm occurs with the gun in the box. Unattended systems can therefore repeatedly perform this
operation as the potlife keeps happening.

4. If one of the guns in not in the GFB, the system will
not perform any of the Mix Fill Push or Auto Dump
operations. The system will retry every 30 seconds
in case the gun is then installed in the GFB.

Mix Fill Push requires a Gun Flush Box for the gun. If
two guns are used, each requires a Fun Flush Box for
this feature to operate. The second Gun Flush Box must
be configured as a Special Output. See Configure
Screen 5 on page 31.

5. With the guns in the GFBs, the system will proportion mixed material through the guns in order to
reset the potlife volume.

Color Change Sequences
FIG. 71 through FIG. 80 illustrate various color change
sequences. See Table 9 to determine which figure to
reference, based on the recipe change and system configuration. The time sequences are detailed in the following paragraphs.
NOTE: For software version 2.04.xxx and older, the system uses the color/catalyst purge and fill times from the
new recipe.
NOTE: See Setup Mode on page 25 to select purge
sources and set desired purge, chop, and fill times.
NOTES:
•

The system uses old recipe data for the purge cycle.
However, it opens the new color/catalyst valve
based on the new recipe data.

•

The system uses the new recipe data for the fill
cycle.

•

For the one gun flush box (GFB) option, the spray
gun must be inserted in the GFB during the entire
color change cycle (purge and fill). The GFB trigger
output will be on during the recipe change cycle.

•

For the two gun flush box (GFB) option, both spray
guns must be inserted in the GFBs during the entire
color change cycle (purge and fill). The system will
turn each GFB trigger output on and off based on
the preset time for each gun.

•

For Special Outputs options, the system will turn
each output on and off based on the preset times.
Each Special Output has two different start times
and durations.

•

For systems without dump valves, the First Purge
begins after the Color/Catalyst Change steps are

Color Change

Color Purge/Dump

First Purge

•

This sequence flushes out the color with solvent,
from the color valve to the Dump A valve.

Select the First Purge Source (air, solvent, or 3rd valve)
and First Purge Time. For most applications, air is
selected.

•

The color change solvent valve and the Dump A
valve open during the Purge Time.

•

The color change solvent valve closes when the
Purge Time expires.

The system purges the old material from the dose
valves to the gun, using only the selected purge media
(usually air). The selected purge valve opens during the
First Purge Time and closes when the time expires.

Color Fill

Chop Cycle

•

This sequence fills the line with the new color all the
way to the Dump A valve.

Select the Chop Type (air/solvent or air/3rd valve) and
Chop Times.

•

The new color valve and the Dump A valve open
during the Fill Time.

•

The new color valve and the Dump A valve close
when the Fill Time expires.

The air purge valve opens only during the air chop
cycle, and the solvent (or 3rd valve) opens only during
the solvent chop cycle. The number of chop cycles is
determined by dividing the Total Chop Time by the sum
of the Air and Solvent Chop Times.

Catalyst Purge/Dump

Final Purge

•

This sequence flushes out the catalyst with solvent,
from the catalyst valve to the Dump B valve.

Select the Final Purge Source (air, solvent, or 3rd valve)
and Final Purge Time. For most applications, solvent is
selected.

•

The catalyst change solvent valve and the Dump B
valve open during the Purge Time.

•

The catalyst change solvent valve closes when the
Purge Time expires.

Catalyst Fill
•

This sequence fills the line with the new catalyst all
the way to the Dump B valve.

•

The new catalyst valve and the Dump B valve open
during the Fill Time.

•

The new catalyst valve and the Dump B valve close
when the Fill Time expires.

The system fills the line with solvent from the dose
valves to the gun, using only the selected purge media
(usually solvent). The selected purge valve opens
during the Final Purge Time and closes when the time
expires.

Fill
This sequence fills the line from the dose valves to the
gun, and is also referred to as the mixed material fill.
The system begins mixing components A and B until the
Fill Time expires.

To Reset Alarm and Restart

System Alarms

NOTE: When an alarm occurs be sure to determine the
E-Code before resetting it. See Table 10. If you forget
which E-Code occurred, use the Alarms Screens (page
24) to view the last 10 alarms, with date and time
stamps.

System alarms alert you of a problem and help prevent
off-ratio spraying. If an alarm occurs, operation stops
and the following occurs:

Cause

Solution

Valve seal or needle/seat are leaking. Check FIG. 11
Repair the valve (see valve manual 312782).
Totals Screen on page 23. If A and B are dosing simultaneously (sequential dosing only), there is a leak.
Sampling valve is leaking.

Tighten or replace valve.

Flow meter fluctuations caused by pressure pulsations.

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 2KS is reading any fluid flow.
4. If the ProMix 2KS 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.
6. If necessary, install pressure regulators or a surge
tank on the fluid inlets to the ProMix 2KS to reduce
the fluid supply pressure. Contact your Graco distributor for information.

Communication between the Color Change Module and
the Fluid Station is interrupted. The fluid control board
fuse is blown.

Solution
•

Verify that all cables are connected securely and that
the Color Change and Booth Control power LEDs
turn on. If the power LED does not turn on, the problem is probably caused by a bad connection. The nut
on the connector must make at least 5 complete
turns to ensure a good connection. If the power LED
still does not light, the cable or board is bad.

•

Check the color change board DIP switch settings.
See the Installation manual.

•

Check the fluid plate board DIP switch setting. An
incorrect setting will not cause E-12 alarms, but a
correct setting will help prevent E-12 caused by electrical noise. See the Installation manual.

•

Check EasyKey software version (displayed at
power up for all versions and when the lock key is
pressed for version 2.02.000 and above). If older
than 1.06.002, upgrade. Be sure to save settings
through BWI or AWI before upgrading, as they will
be erased.

•

The sticker on the color change board shows the
software part number and version, for example
15T270
1.01. If the version is older than 1.01,
replace the board.

•

If all software versions and DIP switch settings are
correct and you still have E-12 alarms, then the system has a bad connection, bad cable, or bad circuit
board. Use a multimeter on the CAN connectors to
test whether there is a good connection between
systems. If there is, you have a bad circuit board. If
there is not, you have a bad connector, connection,
or cable.

E-19: I/O ALARM
Cause

Solution

The Mix and Purge digital inputs are on at the same time. Ensure that only one input is on at a time. At least 1 sec
delay is required when switching from Mix to Purge or
vice versa.
NOTE: The I/O alarm incorporates several sub-alarms relating to internal data issues, as detailed below. These
alarms are only seen in the Alarm log or through BWI or AWI, and may not apply to all software versions.
Fluid Plate Reboot (FP Reboot): Occurs if the system
detects a fluid plate control board reboot or power cycle
not triggered from the EasyKey. The system reverts to
Recipe 61, and mixed material may be in the lines.

Flush the system or perform a color change. If possible,
identify the origin of the reboot or power cycle.

Autokey Lost: Occurs if the Autokey is lost or changed
after having been detected. (A short term loss of the
Autokey will not be registered.) Some system functions
may become unavailable. For example, an automatic
system will not respond to PLC or robot control.

Reinstall the Autokey, or verify that the Autokey is set
properly.

Verify that the source data is from a valid recipe (1-60).
Illegal Source: Occurs if a recipe outside of the range
1-60 is detected as the source data for global recipe data
copies. This is possible if an invalid configuration file is
sent to the EasyKey.

Config Error: Occurs if a configuration file sent to the
EasyKey specifies a different hardware setup than what
exists. For example, the configuration file specifies 2
color change boards but only 1 is present.

Verify that the configuration file specifications and the
hardware conform.

Range Error: Occurs if a valve used in a recipe is not
present in the current hardware setup. For example, a
recipe calls for valve 30 but the system has only 12
valves.

Check if the fill volume is properly configured:
•
•

For systems without color change and with minimum
mixed material fill volume entered, Fuse F1 is blown.

Adjust fill volume.
Adjust fill time.

Verify condition of fuse and replace if necessary. See
Repair-Parts manual.

E-22: TANK A LOW ALARM, E-23: TANK B LOW ALARM, or E-24: TANK S LOW ALARM
Cause
