1. VC Training Table Setup and Floating 9-17-2004

2. Agenda General –Air Supply Requirements Assembly –Assembling the System –Leveling the Table –Isolating the Table Installing Leveling Valves Connecting Air Lines Adjusting Leveling Valves Troubleshooting

3. Air Supply Requirements Constant air supply required during operation Bottled nitrogen Compressed air No CO 2 (cause freezing) –After initial setup air is only consumed to compensate for load changes –Pressure requirements Determined by dividing total payload and table weight by isolator diaphragm area + 10 psi. (Payload weight + Table weight) Total isolator diaphragm area (25.9 in 2 /isolator) + 10 psi

4. Air Pressure Example RS4000-510-8(1250 lbs) Payload( 445 lbs) Total(1695 lbs) (445 + 1250) (4 isolators) * (25.9 in 2 /isolator) + 10 psi 26 psi = Approximate net weights (±10%) for 4 ft (1.2 m) wide steel tables. For 5 ft (1.5 m) wide models add 20%, for 3 ft (0.9 m) models, subtract 25%. Shipping weights can be estimated by adding 100–200 lbs (45–90 kg) for crate weight. RS4000-510-8 Weight = 1000*1.2 = 1,250lbs

5. Assembly – Assembling the system Position isolators per sketch below (standard length tables) –Custom tables – isolator positions will be included in a data package provided with system 16.0 (406) 6.0 (1800) 22.0 (559) 8.0 (2400) 27.0 (686) 10.0 (3000) 32.0 (813) 12.0 (3600) 37.0 (940) 14.0 (4200) 42.0 (1067) 16.0 (4800) 59.1 (1500) 47.0 (1194) 18.0 (5400) 48.0 (1200) 53.0 (1346) 20.0 (6000) 36.0 (900) in. (mm) ft (mm) in. (mm) DIMENSION (A) LENGTH (L) WIDTH (W)

6. Assembly – Assembling the system Bolt isolators to table using clips, bolts and wrench provided

7. Leveling the Table Place a level on the table top in about the center Adjust the support as required to level the table When level, make sure each isolator support is resting against the bottom of the table and is centered between the clips

8. Isolating the Table - Installing Leveling Valves 3 valves are used in all systems regardless of the number of isolators Leveling locations are selected in order to form the largest triangle possible IPV-KT packaged in box IPV valve and associated mounting hardware

9. Isolating the Table - Installing Leveling Valves Mounting screw holes Control arm Table height sensor Over-pressure relief valve Air supply Metering needle valve Isolator pressure gauge Air line to isolator

10. Isolating the Table - Installing Leveling Valves Set the table height sensor adjustment screw to center of travel Attach the leveling valve to isolator using the 2 mounting screws and nut plate provided Rotate control arms on valves “A” to point to the outside of the table Rotate control arm “B” to point to the center of the 2 isolators it is controlling

11. Isolating the Table - Connecting Air Lines Connect air lines to the isolator as shown below (use translucent tubing and tee connectors. Connect grey tubing between the air line to isolator (hose barb) and the isolator A razor blade works best for cutting tubing Translucent tubing Grey tubing Tee connectors

12. Isolating the Table - Connecting Air Lines The adjacent diagrams detail the valve connections to the isolator Translucent tubing One Isolator Two Isolators

13. Isolating the Table – Adjusting Leveling Valves Close metering needle valve on each valve. Re-open 1 / 8 – ¼ turn. Turn on Air supply and adjust to calculated pressure (DO NOT EXCEDE 100psi) If table does not float within 5 minutes, slowly increase pressure or adjust valve height adjustment screw to hold the control arm down further. Be sure metering needle valves are open. If table oscillates reduce pressure and/or close needle valve slightly Metering needle valve Control arm Table height sensor
