MTS Acumen - Manual (Page 99)

a) Calculate how high you need to raise the crosshead to prevent the actuator from contacting anything
even if it goes to full extension. Your calculations should include the fixturing that will be used for
the test.
Note: The stroke for most MTS Acumen load frames is 70 mm (2.76 in).
b) Move the left and right crosshead locks to the fully unlocked position.
c) If necessary, turn Exclusive Control on.
d) Using the crosshead lift controls on the frame-mounted control, move the crosshead up to the height
you calculated earlier.
e) Move the left and right crosshead locks to the fully locked position.
2. Move displacement limits to their maximum values so that actuator movement is not inhibited.
a) In the Axial Displacement Situational Awareness panel, set all four displacement limits to their
maximum value by dragging each slider to its maximum position. This ensures that you have full
actuator travel available to you.
b) Right-click each of the four axial displacement text boxes and set the Limit to On, and the Action
to C-Stop Interlock.
3. Turn on High Power Prohibit.
