System Verification

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.
