PRIMARY MANIFOLD FUNCTIONALITY TESTING -- CONTINUED
9. Turn the power supply off and remove the hydraulic input pressure from the --8 hose connected
to port C2 (front side of manifold). There should not be any hydraulic pressure applied to the
manifold.
10. Remove the power supply cable from valve V14.
11. Install a --8, 37
_
flare nut cap on port C2 (bottom of manifold).
12. Disconnect the --8, 37
_
flare fitting hose on port C2 (front side of manifold).
13. Install a --8, 37
_
flare nut cap on port C2 (front side of manifold).
Circuit 3R
1. Remove the --8, 37
_
flare nut cap on port 3R (front side of manifold).
2. Connect a --8, 37
_
flare fitting hose to port 3R (front side of manifold).
3. Connect a 28 VDC power supply to valve V15.
4. Remove the --8, 37
_
flare nut cap on port 3R (bottom of manifold).
5. Apply hydraulic pressure to the --8 hose port 3R (front side of manifold).
6. Observe fluid flowing from port 3R (bottom of manifold).
7. Remove the --8, 37
_
flare nut cap on port 3R (front side of manifold).
8. Connect a --8, 37
_
flare fitting hose to port 3R (front side of manifold).
9. Connect a 28 VDC power supply to valve V15.
10. Remove the --8, 37
_
flare nut cap on port 3R (bottom of manifold).
11. Apply hydraulic pressure to the --8 hose port 3R (front side of manifold).
12. Observe fluid flowing from port 3R (bottom of manifold).
13. Energize the power supply. Fluid flow should stop coming from port 3R (bottom of manifold).
14. Read and record the T1 voltage.
15. Turn the power supply off and remove the hydraulic input pressure from the --8 hose connected
to port 3R (front side of manifold). There should not be any hydraulic pressure applied to the
manifold.
16. Remove the power supply cable from valve V15.
17. Install a --8, 37
_
flare nut cap on port 3R (bottom of manifold).
18. Disconnect the --8, 37
_
flare fitting hose on port 3R (front side of manifold).
19. Install a --8, 37
_
flare nut cap on port 3R (front side of manifold).
Circuit 3L
1. Remove the --8, 37
_
flare nut cap on port 3L (front side of manifold).
2. Connect a --8, 37
_
flare fitting hose to port 3L (front side of manifold).
3. Connect a 28 VDC power supply to valve V16.
4. Remove the --8, 37
_
flare nut cap on port 3L (bottom of manifold).
