a) If grips are installed, remove them.
b) Turn on system electrical power.
c) Turn on high hydraulic pressure.
2. Set up the load unit:
a) Position the actuator at midstroke.
b) Set and enable the test controller’s upper and lower limit detect interlocks to limit the actuator’s
movement to 2 mm (0.10 in) in each direction.
c) Move the crosshead so that there is about 360 mm (14 in) between the top of the actuator and the
bottom of the force transducer.
d) Lock the crosshead.
Caution:
Alignment takes place in a crush zone with hydraulic pressure on.
Hands can be crushed and equipment can be damaged when hydraulics are turned on.
Be careful when working in a crush zone.
Observe the following to reduce the hazards in this procedure:
Ensure that you set and enable displacement interlocks to limit the actuator’s movement.
Ensure that the crosshead is locked.
Reduce the load unit’s hydraulic pressure to low.
Keep your hands out of the crush zone except when performing the steps needed to
complete this procedure.
e) Turn the load unit’s hydraulic pressure to high.
3. Check the alignment between the force transducer and the actuator.
