Initial startup
Recommended procedure
1. Verify that the following have been completed:
• The frame is secured to the foundation (if required)
• The HPS reservoir is filled with the appropriate amount and type of oil
• The air breather assembly is installed on the fill hole of the HPS reservoir
• All system interconnect cables are installed and have secure connections
• All Operating Instructions and accompanying documentation for the system have been read and
understood by the operator
• Any shipping hardware (typically painted red) has been removed from the frame
• Any crosshead blocking has been removed from the frame, including any type of wooden blocks
or metal plates that secure the crossheads together
2. Locate the Operating Instructions that were supplied with the system. You will be required to refer to
procedures and information that are provided in the Operating Instructions as you perform the initial
startup.
3. Ensure that the test space is clear - there should be no fixtures installed in the test space. This would
exclude any fixtures that were installed at the factory and remained in the test space for shipment.
These fixtures can remain in the test space. Also ensure that there is no shipping hardware on the
frame.
4. Perform the “System Startup” procedure provided in Chapter 3 of the Operating Instructions that
were supplied with the system.
5. Check that the frame is enabled. If the frame will not enable, see “Troubleshooting” on page 44,
specifically Problem No. 2 of the table. Once any problems are corrected, enable the frame.
6. 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”).
7. Us i n g th e 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.
8. For systems with G7-style crossheads, use the grip controls to introduce fluid to the hydraulic grips.
Open and close the grips several times.
9. It is necessary to bleed air from the hydraulic cylinder. This requires a procedure that must be
performed by the Instron service engineer.
10. 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).
11. If the system will not be operated at this time, perform the “System Shutdown” procedure provided in
the System Operating Instructions (supplied separately).
