Flow Control Troubleshooting

Problem: Flow Command does not produce fluid output.

Test the system as follows, to determine if the problem is mechanical or electrical.

1.Install a 0-100 psi (0-0.7 MPa, 0-7.0 bar), 1/8 npt(m) air pressure gauge (not supplied) as follows.

a.For module 249849: Remove the plug from the 1/8 npt(f) air gauge port and install the gauge. See FIG. 71 on page 67.

b.For module 24H989: Install a 1/8 npt(m) x 1/8 npt (fbe) tee in the air outlet port. Install the gauge in one branch of the tee and the air outlet fitting in the other. See FIG. 72 on page 67.

2.Set the system to Manual Override, % Open mode; see steps 2-5under Flow Control Startup on pages 72-73.

3.Set the % Open value to 50. See FIG. 90.
