8. Start the HPS by pressing the
Pump Start
button on the HPS controls; the
FRAME READY
indicator will illuminate. Immediately check the position of the piston within the hydraulic cylinder,
the piston should be positioned so that it is neither fully retracted nor fully extended. Use the jog
controls to move the piston if necessary - typically a separation of 6 mm (0.25 in) is sufficient. If the
piston is in either of these conditions, the servo loop control could build up enough error to shutdown
the HPS (the controlling software will display a “Position loop error”).
9. For frames with a J3-style crosshead, perform the following:
a. Clamp and unclamp the crosshead lock cylinders several times using the controls on the lifts and
locks control unit.
b. Unclamp the crosshead lock cylinders.
c. Cycle the crosshead lift cylinders up and down several times using the controls on the lifts and
locks control unit - be sure to
RAISE
the crosshead first.
d. Position the crosshead so that full stroke of the hydraulic cylinder can be achieved.
e. Clamp the crosshead lock cylinders. The crosshead lock cylinders are now securing the
crosshead to the columns. Do not unclamp the cylinders unless crosshead adjustment is
necessary.
f.
Adjust the crosshead support collars on the columns so that they are in contact with the bottom
of the crosshead (use hex-bit socket and ratchet wrench). Secure the crosshead support collars
to the columns. Tighten the cap screws to the torque specified in
(use hex-bit socket
specified in
and torque wrench).
10. For frames with a J1-style crosshead, raise the crosshead so that full stroke of the hydraulic cylinder
can be achieved. Follow the procedure for manual crosshead adjustment in Chapter 3 of the
Operating Instructions that were supplied with the system.
11. Using the
JOG
controls on the user control panel, stroke the hydraulic cylinder one full cycle to help
bleed air out of the system and introduce hydraulic fluid into the system.
12. Place the
Tension/Compression
switch to
Tension
and use the
JOG
controls on the user
control panel to fully retract the hydraulic cylinder. Once the hydraulic cylinder is fully retracted, place
the
Tension/Compression
switch to
Compression
and use the
JOG
controls to fully extend
the hydraulic cylinder. Repeat this tension-compression cycle 10 times.
13. The system is now ready for normal operation. Before the system is operated any further, be sure to
read and understand the material provided in the System Operating Instructions (supplied
separately).
14. If the system will not be operated at this time, perform the “System Shutdown” procedure provided in
the System Operating Instructions (supplied separately).
When the crosshead is unclamped, it may move up slightly. This is normal operation and is not a cause
for concern.
