System Operation

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 ProMix 2KS controller sends signals to activate the solenoid valves. The solenoid valves activate Dose Valves A and B. Fluid flow begins when the Gun Trigger input is seen.

4.Components A and B are introduced into the fluid integrator (FI) one at a time as follows.

a.Dose Valve A (DVA) opens, and fluid flows into the integrator.

b.Flow Meter A (MA) 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 A 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 B (DVB) opens, and fluid flows into the integrator and is aligned proportionately with component A.

e.Flow Meter B (MB) monitors the fluid volume dispensed and sends electrical pulses to the ProMix 2KS controller.

f.When the target volume is dispensed, Dose Valve B closes.

5.The components are pre-mixed in the integrator, then uniformly blended in the static mixer (SM).

NOTE: To control output from the static mixer to the gun, install an optional fluid pressure regulator.

6.Components A and B are alternately fed into the integrator as long as the Gun Trigger input is seen.

7.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.

8.When the Gun Trigger input is seen again, the Pro- Mix 2KS continues the process where it left off.

NOTE: Operation can be stopped at any time by going to Standby mode (remove Mix input).
