Shut down the system
It is recommended that the system as a whole (frame, control unit, HPS, computer system, peripherals,
etc.) be shut down at the end of each working day or anytime it will sit idle for long periods of time. The
procedure to shut down the system is as follows:
1. Remove any specimen from the fixtures and jog the hydraulic cylinder so that the piston is fully
retracted. For frames with J3-style crossheads, adjust the crosshead support collars on the columns
so that they are in contact with the bottom of the crosshead. Secure the crosshead support collars to
the columns. Tighten the cap screws to a torque of 68 N-m (50 lbf-ft). Also, refer to “Loss of power”
on page 42.
2. Press the DISABLE FRAME button in the controlling software to shut down the HPS.
3. Engage the Emergency Stop button.
4. Exit the controlling software and any other software that is running. Shut down the Windows
Operating System.
5. Turn off all peripheral equipment.
6. Turn the system disconnect switch to OFF ( O ).
If the frame will sit idle between tests, press the DISABLE FRAME button in the controlling software to
shut down the HPS. For added precaution, engage the Emergency Stop button to ensure that the
HPS can not be inadvertently started. Release the Emergency Stop button when ready to run the
next test. Once the HPS is running, 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.
