7. Place a clean container under sampling valve A.
8. Press . Metering pump A light comes on.
9. Dispense fluid A. Slowly open and adjust sampling
valve A (AE) to achieve desired flow. The metering
pump stops automatically when dispense completes
and metering pump A light (DK) turns off and meter-
ing pump B light (DK) turns on.
10. Close sampling valve A (AE).
11. Dispense fluid B as follows:
a.
Batch dispense: move container under sam-
pling valve B (AF).
Ratio check : place clean container under sam-
pling valve B (AF).
b. Slowly open and adjust sampling valve B (AF)
to achieve desired flow. The metering pump
stops automatically when dispense completes.
Metering pump B light (DK) turns off.
c. Close sampling valve B (AF).
12.
Batch dispense: stir material until mixed.
Ratio check : compare net weight of A and B materi-
als dispensed.
Confirm Batch Dispense Test
The Confirm Batch Dispense Test screen displays when
the batch dispense test completes without error. This
screen displays the selected ratio between the metering
pumps and the weight of material dispensed from each
metering pump.
The gray at the bottom of the beaker represents the vol-
ume of material dispensed by metering pump A and the
black at the top of the beaker represents the volume of
material dispensed by pump B.
Enter the weight of each sample in the A and B input
boxes. The system will calculate the ratio and display a
check in the box if it is within tolerance. The result of the
test is also entered in the USB log.
Down Stream Valve Leak Test
This test confirms or troubleshoots leaks in components
located down stream of the dosing valves. Use this test
to detect closed or worn valves, and to detect leaks in
circulation valves installed at a remote mix manifold.
1. Close both mix manifold valves downstream of the
dosing valves.
2. Close recirculation valves (AC, AD).
