Procedure for initial pneumatic counterbalance setup:

Section 1.4.
to continuing.
1. Verify that the stage is mounted and the shipping brackets are secure.
2. Loosen all shipping bracket mounting screws (M3 BHCS) by one or two turns, but do not remove the
screws. This will allow a small amount of travel for counterbalance setup.
3. Connect the airline to the air supply, and slowly turn on the supply pressure to the counterbalance. The
pressure supply should exceed the pressure determined by
a. The tabletop should still be hanging from the loose shipping brackets. If the tabletop starts to
slowly rise, gradually lower the air supply pressure using the stage's regulator knob (refer to
1-1) until the carriage hangs from the shipping brackets. Counterclockwise rotation of the knob
decreases the pressure to the counterbalance cylinder.
4. Slowly increase pressure to the cylinder (clockwise rotation of the regulator knob) until the carriage just
starts to rise. Adjust the pressure with the regulator such that when you move the carriage to a new
position by hand, the carriage neither rises nor falls.
5. The system is now balanced.
6. Remove the shipping brackets from the base. Retain the shipping brackets for future use.
7. Proceed with the electrical installation and test the motion control system in accordance with the
system documentation. For information on electrical connections, refer to
To turn off the air supply to the stage once the shipping brackets have been removed:
1. Make sure the stage is not under servo control.
2. Gently push the carriage down to the bottom of travel until the mechanical shock engages.
3. Turn off the counterbalance pressure. Once the counterbalance pressure has completely bled out,
release the hand pressure on the carriage.
