Pump Pressure Check

NOTE: Enter the transducer calibration data before doing the pressure check.

Perform the pressure check:

•The ﬁrst time the system is operated.

•Whenever new materials are used in the system, especially if the materials have viscosities that differ signiﬁcantly.

•At least once per month as part of regular maintenance.

•Whenever a pump is serviced or replaced.

During each pressure test, the dose valve will close during an up stroke and a down stroke (in either order). This test is to verify that the valves are seating properly and not leaking. If leaking occurs, the system will alarm after the test for that particular pump direction.

NOTE: Do not trigger the spray device during the pressure check.

1.The pump and lines must be primed with color or catalyst before doing the Pressure Check. See Prime and Fill the System, page 20.

2.If the display is on a Run Mode screen, press

to access setup screens.

3.Scroll to Calibrate to display Calibrate Screen 1, page 77.

4.Press the Pressure Check button for the desired pump. The pump will build pressure in the line to a minimum of the Stall Test Pressure. The pump will then move to the center stroke position and stall test the upstroke, followed by the downstroke.

5.The pressure and ﬂow that the unit measured are displayed on the screen. Compare with the maximum leak rate entered on System Screen 2, page 68. If the values are substantially different, repeat the test.

NOTE: The stall test pressure set point is a minimum. The system may stall at a higher pressure depending on hose lengths and ﬂuid composition.
