Horn
- In the top center of the panel is a horn that indicates
when the controller has turned on the "Fault" output from
the gun.
Total Flow
- This is an LCD display that indictes the current
flow rate out of the applicator (or applicators, if multiple
applicators are fed from one fluid panel). It operates from
an analog output signal from the controller with 0 VDC being
0 cc'min. and 10 VDC scaled to 2000 cc/min.
Flow Control
- This is a potentiometer that varies the
analog flow control voltage into the channel card from 0
volts DC to 10 volts DC. Users can program what flow rate
they want for both extremes by using the Minimum Flow
and Maximum Flow parameters under the edit gun screen.
Faulted/Fault Reset
- This is a red illuminated push-button.
The lamp will be illuminated anytime a fault occurs. Pushing
this button resets any fault that has caused the fault. After
resetting a fault, the user must then push the Ready Run push-
button to put the gun back into run mode to resume spraying.
Ready/Run
- This is a green illuminated push-button.
Pushing this button puts a gun into run mode. When in run
mode, the green lamp is illuminated. It is extinguished in
either a halted or faulted state.
Guns in Flush Box
- These are two LED's that indicate when
up to two spray guns are in their respective flush boxes.
A flush or load sequence will not be allowed to start until
both of these indicators are illuminated. These LED's are
connected to four pressure switches, which are actuated
by the two flush boxes. The signal from these pressure
switches also feed the Paint Fill and Purge push-buttons
to prevent color changes and purges from occurring unless
the guns are in their flush boxes and the boxes are closed.
These pressure switches should be jumpered if gun flush
boxes are not to be used. There are jumpers on the PC
board inside the panel to bypass these pressure switches.
Feather Reset
- This push-button is not functional when
used in a DynaFlow system.
Spray Test -
This is a simple push-button that sends a trigger
signal back to the controller and also turns on the trigger
solenoid to allow operators to verify and test flow, etc. Note
that this button is only functional if fluid has been loaded
(i.e., the green Paint Filled indicator lamp is illuminated).
FLOW LIMITATIONS
Because of the way the DynaFlow determines flow rate
from a flowmeter, it has limitations where it can no longer
detect flow at the low end and at the high end. (It uses a
software timer to determine the time between pulses rather
than a high speed counter card.) The low end limitation
is because the timer overflows between pulses and at the
high end, the scan time of the program cannot keep up
with the speed of the incoming pulses.
Because of this fact, the DynaFlow cannot see flow at the low
end when the pulses fall below 1 Hz (one pulse every second).
• With a gear-type flowmeter calibrated to 4,500 pulses/
liter, the DynaFlow will not detect flow below 13.3 cc/min.
• With a gear-type flowmeter calibrated to 8,000 pulses/
liter, the DynaFlow will not detect flow below 7.5 cc/min.
• With a gear-type flowmeter calibrated to 40,000 pulses/
liter, the DynaFlow will not detect flow below 1.5 cc/min.
• With a piston flowmeter calibrated to 60,000 pulse/liter,
the DynaFlow will not detect flow below 1 cc/min.
ADDENDUM C:
At the high end, the DynaFlow cannot see flow when the
pulses exceed 435 Hz.
• With gear-type flowmeter calibrated to 4,500 pulses/liter,
the DynaFlow will not detect flow above 5,800 cc/min.
• With gear-type flowmeter calibrated to 8,000 pulses per
liter, the DynaFlow will not detect flow above 3,275 cc/min.
• With a gear-type flowmeter calibrated t 40,000 pulses/
liter, the DynaFlow will not detect flow above 655 cc/min.
• With a piston flowmeter calibrated to 60,000 pulses/liter,
the DynaFlow will not detect flow above 435 cc/min.
