PRIMARY MANIFOLD FUNCTIONALITY TESTING -- CONTINUED
c.
Testing hydraulic circuits from ports C2, 3R, 3L, 17L, and 19 (all are on the front side of the manifold) to
ports C2, 3R, 3L, 17L, and 19 (all are on the bottom of the manifold).
Circuit C2
1. Remove the --8, 37
_
flare nut cap on port C2 (front side of manifold).
2. Connect a --8, 37
_
flare fitting hose to port C2 (front side of manifold).
3. Connect a 28 VDC power supply to valve V14.
4. Remove the --8, 37
_
flare nut cap on port C2 (bottom of manifold).
5. Apply hydraulic pressure to the --8 hose port C2 (front side of manifold).
6. Observe fluid flowing from port C2 (bottom of manifold).
7. Energize the power supply. Fluid should stop coming from port C2 (bottom of manifold).
8. Read and record the T1 voltage.
