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 vis- cosity. If used, this partially cured ISO will reduce perfor- mance 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.
???Use
???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 con- taminated from the other side.
???Always lubricate threaded parts with ISO pump oil or grease when reassembling.
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.

Dynamic Dosing
In typical operation (ratios 1:1 and above), component A dispenses constantly. Component B dispenses intermit- tently in the necessary volume to attain the mix ratio.
General Operating Cycle, Dynamic Dosing
Overview
Dynamic Dosing provides
A restrictor injects component B into a continuous stream of component A. The software controls the dura- tion and frequency of each injection. See FIG. 52 for a schematic diagram of the process.
Dynamic Dosing System Parameters
The following parameters affect dynamic dosing perfor- mance:
???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
???Component B Pressure: Ensure precise pressure regulation. It is recommended that the component B pressure be
NOTE: When using dynamic dosing it is very important to maintain a constant,
Select a Component B Restrictor Size
If you cannot maintain the desired flow and spraying ratio, you may need to select a different restrictor. Use the charts on pages 61 to 65 to select an appropriate restrictor size based on the desired flow and mix ratio.
Balancing A/B Pressure
If component B pressure is too high, it will push the com- ponent 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. 50 shows the A to B pressure balance, read at the proportioner inlet. It is recommended that the compo- nent B pressure be
NOTE: In
In dynamic dosing, component A dose valve is con- stantly 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 pressure readings for each pump on Run Pump Control (Screen 15).

Air Flow Switch (AFS) Function
Air or
The air flow switch (AFS) detects air flow to the gun and signals the ProMix 2KE controller when the gun is trig- gered. The gun icon on the Display Module shows spray when the AFS is activated.
If a pump fails, pure resin or catalyst could spray indefi- nitely if the ProMix 2KE does not detect the condition and intervene, which is why the AFS is so important.
If the ProMix 2KE detects through the AFS signal that the gun is triggered, yet one or both of the pumps are not running, a Dose Time Alarm (QTA1 or QTB1) occurs after 40 seconds and the system goes into Standby.
NOTE: Systems with a 45:1 pump ratio are designed for use with an airless gun. These systems contain no air flow switch and are set up so that they do not trigger a System Idle Warning.
NOTE: For airless applications with other pump ratios, the air flow switch can be disabled on Configure 2 (Screen 19).
System Errors
System Idle Warning (IDLE)
This warning occurs if the ProMix 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. This warning is not active in systems with a 45:1 pump ratio, using an airless gun.
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 ,
then , then trigger the gun.
