ABL1500Z Hardware Manual
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. Gently push the stage down through the shock stroke until the shock bottoms out and hold the carriage
in this position.
4. Turn off the counterbalance pressure. Once the counterbalance pressure has completely bled out,
release the hand pressure on the carriage.
5. Turn off the air bearing supply.
To change the payload on the stage (add or remove mass):
1. Follow the steps above to turn off the air to the stage.
2. Turn the regulator knob counterclockwise until it bottoms out (prevents any pressure from reaching the
cylinders).
3. Change the payload as required. See
charts.
4. Estimate the pressure required to lift the payload using
5. Turn on the air supply to the air bearing.
6. Turn on the air supply to the counterbalance input.
7. Gradually increase the pressure to the cylinders with the precision regulator. Make fine adjustments
when approaching the estimated pressure required for counterbalance. Adjust until the payload does
not rise or fall when put into a position by hand.
