PRIMARY MANIFOLD FUNCTIONALITY TESTING -- CONTINUED
17. Install a --8, 37
_
flare nut cap on port 3L (bottom of manifold).
18. Disconnect the --8, 37
_
flare fitting hose on port 3L (front side of manifold).
19. Install a --8, 37
_
flare nut cap on port 3L (front side of manifold).
Circuit 17L
1. Remove the --8, 37
_
flare nut cap on port 17L (front side of manifold).
2. Connect a --8, 37
_
flare fitting hose to port 17L (front side of manifold).
3. Connect a 28 VDC power supply to valve V11.
4. Remove the --8, 37
_
flare nut cap on port 17L (bottom of manifold).
5. Apply hydraulic pressure to the --8 hose port 17L (front side of manifold).
6. Observe fluid flowing from port 17L (bottom of manifold).
7. Remove the --8, 37
_
flare nut cap on port 17L (front side of manifold).
8. Connect a --8, 37
_
flare fitting hose to port 17L (front side of manifold).
9. Connect a 28 VDC power supply to valve V11.
10. Remove the --8, 37
_
flare nut cap on port 17L (bottom of manifold).
11. Apply hydraulic pressure of 3000 psig (20684.27 kilopascal) @ 10 GPM (37854.12 CPM) to the
--8 hose port 17L (front side of manifold).
12. Observe fluid flowing from port 17L (bottom of manifold).
13. Energize the power supply. Fluid flow should stop coming from port 17L (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 17L (front side of manifold). There should not be any hydraulic pressure applied to the
manifold.
16. Remove the power supply cable from valve V11.
17. Install a --8, 37
_
flare nut cap on port 17L (bottom of manifold).
18. Disconnect the --8, 37
_
flare fitting hose on port 17L (front side of manifold).
19. Install a --8, 37
_
flare nut cap on port 17L (front side of manifold).
Circuit 19
1. Remove the --8, 37
_
flare nut cap on port 19 (front side of manifold).
2. Connect a --8, 37
_
flare fitting hose to port 19 (front side of manifold).
3. Connect a 28 VDC power supply to valve V17.
4. Remove the --8, 37
_
flare nut cap on port 19 (bottom of manifold).
5. Apply hydraulic pressure of 3000 psig (20684.27 kilopascal) @ 10 GPM (37854.12 CPM) to the
--8 hose port 19 (front side of manifold).
6. Observe fluid flowing from port 19 (bottom of manifold).
