ProMix™ II General Operating Cycle

2.
The operator presses the Mix
key to begin
operation.
3.
The controller sends signals to activate the sole-
noid valves. The solenoid valves activate Dispense
Valves A and B. Fluid flow begins when the gun is
triggered.
4.
Components A and B are introduced into the inte-
grator chamber (K) one at a time, through separate
fluid lines, check valves, and flow meters.
a.
Dispense Valve A opens, and fluid flows into
the integrator chamber.
b.
Flow Meter A (C) monitors the fluid volume
dispensed and sends electrical pulses to the
controller. The controller monitors these
pulses and signals.
c.
When the target volume dispenses, Dispense
Valve A closes.
d.
Dispense Valve B opens, and fluid flows into
the integrator chamber (K) and is aligned pro-
portionately with component A.
e.
Flow Meter B (G) monitors the fluid volume
dispensed and sends electrical pulses to the
controller.
f.
When the target volume is dispensed, Dis-
pense Valve B closes.
5.
The components are pre-mixed in the integrator
(K), then uniformly blended in the static mixer
tube L).
6.
Components A and B are alternately fed into the
integrator (K) as long as the gun is triggered.
7.
If the gun is not triggered for two minutes, the sys-
tem switches to Idle mode, which closes off the mix
manifold dispense valves.
8.
When the gun is triggered again, the ProMix™ II
continues the process where it left off.
Adaptive Overrun Correction
The actual volume of fluid dispensed each cycle can
vary slightly from the calculated target. However, the
controller monitors this variance and makes adjustments
to keep the ratio of component B to A within a user spec-
ified tolerance.
1.
The spray gun operator enters and loads the
desired color. The color change LED blinks while
color is loading, then turns solid when complete.
Operator Station Screen
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 controller.
Color
LED
An optional fluid pressure regulator can be installed
to control output from the static mixer tube to the
spray gun.
Operation can be stopped at any time by pressing
the Standby
key or shutting off the main power
switch.
