Sequential Dosing
Components A and B dispense sequentially in the nec-
essary volumes to attain the mix ratio.
1. The operator presses
to begin operation.
2. The ProMix 2KE controller sends signals to activate
the solenoid valves. The solenoid valves activate
Dose Valves A1 (A2 or A3, depending on recipe
selection) and B. Fluid flow begins when the gun is
triggered.
3. Components A1 and B are introduced into the fluid
integrator (FI) one at a time as follows.
a. The A side dose valve (DVA1, DAV2, or DVA3)
opens, and fluid flows into the integrator.
b. Flow Meter A (MA) monitors the fluid volume
dispensed and sends electrical pulses to the
ProMix 2KE 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 2KE 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 2KE controller.
f. When the target volume is dispensed, Dose
Valve B closes.
4. 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.
5. Components A and B are alternately fed into the
integrator as long as the gun is triggered.
6. If the gun is not triggered for two minutes, the sys-
tem switches to Idle mode, which closes off the mix
manifold dose valves.
7. When the gun is triggered again, the ProMix 2KE
continues the process where it left off.
NOTE: Operation can be stopped at any time by
pressing or shutting off the main power
switch.
