Parameters
The controlling parameters for each GUN, and for the
CHANNELs assigned to that GUN, are called JOBs
(also commonly referred to as PSETs, Color Tables or
Recipes). The JOB values define flow characteristics
such as TARGET FLOW RATE, MIX RATIO, FLOW
TOLERANCE, etc. JOBs include all of the parameters
that may be dependent on the material used. This of-
fers the ability to optimize system control as needed
per material and then recall the settings each time
that material is requested. There are up to 100 JOB
#s for each GUN. By saving frequently used JOB #s
to memory you can later recall them by loading the
number representing that JOB #. The parameters are
viewed and edited through the local Operator Interface
or through a remote host computer.
A set of initial parameter values is included in the
controller. The initial (default) values determine the
operating conditions of the controller when started
for the first time. Some of these will need to be edited
during initial setup based on the installation.
2. If the output of Gun 2 supplies a single appl-icator, then an
MVR should be used for the Master Channel flow controller
and Gun 2 should be operated in Auto mode.
3. If the output of Gun 2 supplies multiple appl-icators other
then hand guns, then Gun 2 should be operated in Manual
mode using a CCV for the Master Channel flow controller.
Additional Guns should be configured for each applicator
as shown below to provide automatic flow control for
each applicator.

Components)
Flow Controller = DR1
Flow Meter = Gear-Type
Operating Mode = Auto
4. Minimum flow rate for the DynaFlow is deter-mined for
each channel based on the number of pulses/liter for the
flow meter for the channel. (Refer to "Addendum C" for
flow limitations.)
PARAMETER DESCRIPTIONS
CONFIG SYSTEM (F1)
All system parameters are password protected, unless
disabled by setting the password to zero (0). Any time an
operator wishes to change any of these parameters, they
are prompted for the password. The password only needs
to be entered once as long as the time between keystrokes
does not exceed the Password Timer as described below.
System parameters may be edited at any time regardless
of the operating mode if no system errors exist. Any active
system errors must be cleared.
Horn Code
This is a coded number that represents when the supervi-
sor would like the System Fault output relay to energize.
This output is normally connected to a horn. The options
desired are selected.
0 = No horn
1 = Horn when controller faults
2 = Horn when pot-life timer has expired
4 = Horn when external fault is detected
Blow Off Time
This parameter is used only if the GUN is configured as a
manual GUN. The software monitors the trigger signal to
identify when the spray GUN is triggered. (Typically this
signal comes from an air flow switch located in the atomi-
zation air line.) If the software ever detects a GUN trigger
signal without pulses from the master channel flow meter
after the ‘Blow Off’ time has elapsed, a No Master Flow
fault is issued. This prevents a painter from painting if the
flow meter sticks. In some manual applications, painters
will only trigger the spray GUN enough to get atomization
NOTE
†
Any modifications to the System Parameters
screen data are saved only when the operator
presses the "Store Data" key (F5), otherwise the
modifications will be lost when the screen is exited
with the escape (ESC) key.
