OPERATION
OVERVIEW
This section will acquaint you with the general
operation of the DynaFlow Fluid Flow Controller.
The following information describing CHANNELs,
GUNs and PARAMETERS summarize the three
main features that form the basis of the fluid flow
controller.
CHANNELs
A CHANNEL consists of an electrical-to-pneumatic
(E/P) transducer, a material regulator and a fluid
flow meter combination through which a single
material is controlled. One or two CHANNELs
may be configured for each GUN. Two-component
systems (sometimes referred to as 2K systems)
have two CHANNELs assigned to a single GUN.
Single-component systems (sometimes referred
to as 1K systems) have only one CHANNEL as-
signed to a single GUN.
Each DynaFlow control system has up to 8
CHANNELs available that can be configured to
suit the application. For example, you can use 4
CHANNELs assigned to 2 GUNs to spray 2 dual
component paints on automatic machines, and 2
CHANNELs assigned to 1 GUN to spray one dual
component paint with a manual hand spray GUN.
Please note that most GUN parameters also
apply to single-component control as well. The
CHANNEL that has the greatest flow rate in two-
component systems is typically called the Master
CHANNEL. A CHANNEL cannot be assigned to
more than one GUN.
GUNs
A GUN represents a single applicator through
which one or two materials are delivered.
If you are using single-component coatings, the
DynaFlow controller can support 8 separate single
CHANNEL GUNs operating simultaneously. If
you are using two-component materials, then 4
separate 2-CHANNEL GUNs operating
simultaneously can be supported. Adjacent
CHANNELs (1 & 2, 3 & 4, 5 & 6, and 7 & 8) can
be linked together, using 1 of 8 GUNs, to control
the flow and mixing regulation of two-component
materials. A GUN configured for two-component
operation can also operate in single-component
control mode by setting the ratio to 99, or higher.
Three Component (3-K) Operation
DynaFlow was designed for either single or two-
component operation. Three-component operation
is possible by configuring two, two-component,
guns. The first Gun is set up as follows:
Gun 1 =
Master Channel =
Material = Resin
Flow Controller = Color Change Value
(CCV)
Flow Meter = Standard Gear-Type
Slave Channel =
Material = 2 nd Component
Flow Controller = MVR, with appropriate
size needle
Flow Meter = Piston or Gear-Type,
depending on min/max
flow rates (see Notes 4 and 5)
Operating Mode = Manual
The output of the first Gun is then fed into the
Master Channel input of the second Gun. The
second Gun is setup as follows:
Gun 2 =
Master Channel =
Material = Output of Gun 1 (Resin + 2 nd
Component)
Flow Controller = Color Change Value (CCV)
(see Notes 1, 2, and 3)
Flow Meter = Gear-Type
