Procedure for initial pneumatic counterbalance setup:
IMPORTANT: Refer to
meets specifications before you continue.
1. Make sure that the stage is mounted and the shipping brackets are secure.
2. Loosen all shipping bracket mounting screws 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 regulator knob (refer to
Figure
1-3) 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. 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
Installation.
To turn off the air supply to the stage after the shipping brackets are 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.
