Calibration Mode
The first time that the system is operated after installation or
when using new fluids, calibration is recommended for the
flow meters (CHANNELs). There are several procedures
that can be used for calibration (see the Calibration Mode
Section). Flow meters can be calibrated by fluid weight or
by fluid volume. All calibration measurements are metric,
such as weight is measured in grams and volume in cubic
centimeters (cc).
Procedure 1 (Manual)
1. Place the controller in Calibration Mode - select manual
procedure.
2. Place a graduated container beneath the cal-ibration
valve or applicator paint feed tube/nozzle.
3. Start fluid flow. Open the calibration valve or trigger the
GUN.
Code, located in the System configuration table, determines
if a Pot-Life Fault activates the horn. A Pot-Life Fault can
only be reset by eliminating the expired material from the
fluid lines, or by setting the Pot Life Time to zero in the
JOB Parameters. The horn will be turned off, however by
issuing a Clear Faults command. A Pot-Life Fault
does
not
turn off the GUN.
The DynaFlow system uses the Mixed Volume and the
Pot-Life Time when it monitors the flow rate of the Gun.
Pot-Life is monitored by dividing the Mixed Volume into
40 equal sized "buckets" of material. When an amount
of material has flowed that equals the "bucket" volume,
the 40 "'buckets" are time-shifted so the oldest "bucket" is
eliminated, representing the material that has vacated the
Mixed Volume tubing at the GUN, and a new 'bucket' is
added. If the GUN is in either Run or Load mode, a time
value of 1 second is placed in the new "bucket" to represent
mixed material. If the GUN is in Clean mode, a time value
of zero is placed in the new "bucket" representing solvent.
Every second, the time values stored in the "buckets" are
incremented if they are nonzero (i.e. contain mixed material
vs. solvent). A Pot-Life alarm condition exists if any of the
40 "buckets" contains a time value greater than the Pot-
Life Time (see JOB parameters). A Pot-Life alarm may
be cleared by entering a Pot-Life Time of zero seconds.
4. Collect fluid manually into the graduated container for
a specific time.
5. Stop fluid flow.
6. Select "Stop Cal".
7. Measure the amount of fluid collected.
8. Enter the measured volume of fluid.
9. Accept or reject the new Pulses Per Liter number that
the controller calculated. The flow meter calibration will
automatically be updated.
Required:
- Specific gravity of material
- Digital scale, accurate to 0.10 grams
1. Weigh the empty beaker and record the tare weight
for later calculations.
2. Enter the calibration mode for the desired CHANNEL.
3. Perform the desired collection procedure above.
4. Weigh the fluid in the beaker and subtract the beaker
tare weight to get the net weight of the fluid collected.
5. Entered the measured weight.
