7. Dispense fluid A. Slowly open and adjust sampling
valve A (AE) to achieve desired flow. The pump
stops automatically when dispense completes.
Pump A light (DK) turns off, Pump B light (DK) turns
on.
8. Close sampling valve A (AE).
9. 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 pump stops auto-
matically when dispense completes. Pump B
light (DK) turns off.
c. Close sampling valve B (AF).
10. Batch dispense: stir material until mixed.
Ratio check: compare A and B fluid 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 pumps
and the volume of material dispensed from each pump.
The gray at the bottom of the beaker represents the vol-
ume of material dispensed by pump A and the black at
the top of the beaker represents the volume of material
dispensed by pump B.
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).
3. Enter Test mode in the run (fluid control) screen.
See Test Screens on page 71. Select
to run
down stream valve leak test.
4. Select
. Press . Ensure dosing valves
(AA, AB) are open by verifying blue LEDs are illumi-
nated for both dosing valves.
5. If test is successful, both pumps will stall against the
down stream valves when the dosing valves (AA,
AB) are open. If any movement is detected in the
pumps after stalling, an alarm is issued indicating
which side has a leak.
