Installation Procedure
Installation
B. Restrain the control panel and remove the four screws securing the
panel to the base.
C. Grasp the control panel and slowly lower it to the mechanical stop of
the securing cables.
5. Install the grip control module in the control panel.
Refer to the drawings that accompany the module and the illustrations on
Do not use hydraulic hoses rated for less than 21 MPa (3000 psi).
Under-rated hoses may rupture and can cause injury to personnel or
damage to equipment.
Use only hydraulic hoses that have a working pressure greater than 21 MPa
(3000 psi).
6. Connect the hydraulics.
A. Connect the pressure (“P”) and drain (“D”) ports on the grip manifold
to the corresponding pressure and drain ports on the hydraulic lift/lock
manifold.
B. Connect the grip and release ports on the grip manifold to the
corresponding grip and release ports on each of the upper and lower
grips.
7. Switch electrical power on at the test controller.
Do not turn hydraulic pressure on without verifying that the control channel
error is zero.
A nonzero error may result in unexpected actuator movement and can
cause injury to personnel or damage to equipment.
Verify that the control channel error is zero before applying hydraulic pressure.
8. Turn load unit hydraulic pressure to low.
Inspect for leaks at all connections. If there are leaks, turn off hydraulic
pressure and correct them.
9. Turn load unit hydraulic pressure to high.
Inspect for leaks at all connections. If there are leaks, turn off hydraulic
pressure and correct them.
