System Operation
Operation Modes
Mix
System mixes and dispenses material.
Standby
Stops the system.
Purge
Purges the system, using air and solvent.
Sequential Dosing
Components A, B, and C dispense sequentially in the
necessary volumes to attain the mix ratio.
Recipe (Color) Change
The process when the system automatically flushes out
the old color and loads a new color. See pages 64-76.
General Operating Cycle,
Sequential Dosing
1. The spray gun operator enters and loads the
desired recipe. The color change LED blinks while
recipe is loading, then turns solid when complete.
2. The operator presses the Mix key to begin
operation.
3. The controller sends signals to activate the solenoid
valves. The solenoid valves activate Dose Valves A,
B, and C. Fluid flow begins when the gun is trig-
gered.
Stage 1 (see FIG. 50, ProMix 2KS Detail)
4. Components A and B are introduced into the 2KS
fluid integrator (FI) one at a time as follows.
a. Dose Valve B (DVB) opens, and fluid flows into
the integrator.
b. Flow Meter B (MB) monitors the fluid volume
dispensed and sends electrical pulses to the
ProMix 2KS controller. The controller monitors
these pulses and signals.
c. When the target volume dispenses, Dose Valve
B 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 2KS controller.
d. Dose Valve A (DVA) opens, and fluid flows into
the 2KS integrator and is aligned proportion-
ately with component B.
e. Flow Meter A (MA) monitors the fluid volume
dispensed and sends electrical pulses to the
ProMix 2KS controller.
f. When the target volume is dispensed, Dose
Valve A closes.
