System Operation
66 313885C
General Operating Cycle,
Sequential Dosing
1. The system enters and loads the desired color.
2. The system enters Mix mode 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 Trigger
input is seen.
Stage 1 (see FIG. 68, 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 components A and
B is based on the mix ratio and dose size set by the
user and calculated by the 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.
5. Components A and B are pre-mixed in the 2KS inte-
grator, then uniformly blended in the 2KS static
mixer (SM) before flowing through the hose to the
3KS Fluid Manifold inlet.
Stage 2 (see FIG. 68, ProMix 3KS Detail)
6. Dose Valve C (DVC) opens, and fluid flows into the
3KS integrator and is aligned proportionately with
components A+B (mixed in Stage 1).
7. Flow Meter C (MC) monitors the fluid volume dis-
pensed and sends electrical pulses to the ProMix
3KS controller.
8. When the target volume is dispensed, Dose Valve C
closes.
9. Components A+B and C are pre-mixed in the 3KS
integrator, then uniformly blended in the 3KS static
mixer (SM).
NOTE: To control output from the 3KS static mixer
to the gun, install an optional fluid pressure regula-
tor.
10. Components A+B and C are alternately fed into the
3KS integrator as long as the Gun Trigger input is
seen.
11. If the Gun Trigger input is not seen for two minutes,
the system switches to Idle mode, which closes off
the mix manifold dose valves.
12. When the Gun Trigger input is seen again, the Pro-
Mix 3KS continues the process where it left off.
NOTE: Operation can be stopped at any time by
going to Standby mode (remove Mix input).
