FORWARD RIGHT MANIFOLD FUNCTIONALITY TESTING -- CONTINUED

c.

Testing hydraulic circuit port 11 (side of manifold) to ports 11A and 11B on the top of the manifold.

1. Connect transducer test cable to T11.

2. Connect --6 pressure hose with 37

_

flare fitting to port 11 on side of the manifold.

3. Connect valve test cable from 28 VDC power supply to valves V2 and V10. Do not energize the

power supply at this time.

4. Pressurize port 11 hose to 1000 psig (6894.757 kilopascal) and flow of approximately 5 GPM

(18927.06 CPM) and verify flow is exiting from ports 11A and 11B and that no fluid is flowing

from any other manifold ports.

5. Energize 28 VDC power supply and verify flow from ports 11A and 11B has stopped.

6. Read the voltage at T11.

7. De--pressurize port 11 hose and de--energize 28 VDC power supply.

8. Disconnect --4 pressure hose from port 11 and disconnect valve test cables from valves V2 and

V10. Disconnect T11 transducer cable.

9. This completes the manifold functionality test.
