Basic Operation
32 3A0868G
10. After the volume for A or B is entered, the ProMix
2KE controller calculates the new pump factor and
shows it on Calibration 1 (Screen 22) and Calibra-
tion 2 (Screen 23).
11. Before you begin production, clear the system of
solvent and prime it with material.
a. Go to Mix mode.
b. Trigger the gun into a grounded metal pail until
mixed material flows from the gun nozzle.
Spraying
NOTE: See Run Mode Details, pages 39-41, for further
screen information, if needed.
1. Calibrate the pumps as described in Pump Calibra-
tion, page 31. Pump factors will update automati-
cally based on calibration results. Make additional
manual changes, if desired, as described in Cali-
bration 1 and 2 (Screens 22 and 23), page 46.
Adjust the flow rate.
2. Press . The system will load the correct potlife
volume based on hose length and diameter entered
on Configure 2 (Screen 19). Once material is
loaded, the system returns to Standby. Press
again to spray the loaded recipe.
3. Adjust the flow rate. The fluid flow rate shown on the
Display Module screen is for either component A or
B, depending on which dose valve is open.
If the fluid flow rate is too low: increase air pres-
sure 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 reg-
ulated 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.
Purging
NOTE: See Run Mode Details, pages 39-41, for further
screen information, if needed.
There are 2 purging procedures in this manual:
• Purging Mixed Material
• Purging Fluid Supply System
Use the criteria listed for each procedure to determine
which procedure to use.

NOTICE
Do not allow a fluid supply tank to run empty. It is pos-
sible 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.
