Appendix A
Batch Dispense Test
This screen enables users to dispense a selected total volume of material on ratio. For example, 1000 ml at 4:1
=800 ml of A + 200 ml of B. The total batch volume can be selected from the drop down menu.
When the pump is active it flashes in black on the screen. When the pump completes dispensing it dis- plays in gray on the screen
Down Stream Valve Leak Test
This screen enables users to test for closed or worn valves down stream of the A and B dosing control valves. It can be used to test the mix manifold shut- off/check valves or any remote circulation valves.
While running the test, if there is continuous pump movement on the A or B side, an error will be issued. The error indicates a leak in the valve.
There is no confirmation screen for this test. However, if the down stream valve leak test fails, an warning is issued to indicate the cause of the failure.
Confirm Batch Dispense Test
This screen displays when the batch dispense test com- pletes without error. This screen displays the selected ratio between the pumps and the volume of material dis- pensed from each pump. The gray at the bottom of the beaker represents the volume of material dispensed by pump A. The black at the top of the beaker represents the volume of material dispensed by pump B.
