Vibration Isolation Systems Setup Guide, 2017 System 1 Modular Post-Mount Supports System 1 Modular Post-Mount Support Introduction System 1 is a family of modular post mounted Vibration Isolators and Rigid Leveling Stands that can be configured as follows. 4-post or 6-post sets bolted together in a rigid corral frame. Individual, free standing posts with oversize baseplates. Structural Posts: The structural posts are formed from heavy gauge 3/16 and 1/8 inch thick steel configured with either a Rigid Support leveling jack screw or a Vibration Isolation System. The base of each post can be left...

Vibration Isolation Systems Setup Guide, 2017 System 1 Modular Post-Mount Supports Installation Procedure Tie-bar Installation (Installation steps for systems equipped with tie-bars only.) Systems are designed to optionally add a second row of tie-bars, one row at the top and a second at the base for custom applications. Systems equipped with tie-bars are typically supplied with one row for mounting near the top of the posts. Tie-bars longer than 40 inches: Systems requiring tie-bars longer than 40 inches achieve this length by joining two short tie-bars bolted end-toend with a spacer plate....

Vibration Isolation Systems Setup Guide, 2017 System 1 Modular Post-Mount Supports Step 2 Assemble posts into a rectangular frame with 3/8-16 hex head bolts & nuts and using a 9/16 inch socket wrench. Tie-bars greater than 40 inches in length ■ Tie-bars having a total length greater than 40 inches first require bolting two shorter tie-bars together end-to-end using an alignment spacer plate. Reference figure below. ■ Identify correct combination of short tie-bars for connecting together by first observing system part number and then correlate the last two digits with table below for both the...

Air Supply Input Connection Step 1 Plumb tubing between air supply and system’s input air filter as appropriate. Fittings: Tubing can be connected to a 1/4 or 1/8 inch NPT female fitting as shown in figure below. Adapter Straight Connector 1/4" OD Tubing 1/4" NPT Male to 1/8" NPT Male Thread 1/8" NPT Female Figure 4, Air Supply Input...

Vibration Isolation Systems Setup Guide, 2017 System 1 Modular Post-Mount Supports Figure 6, Typical valve schematic for a 6 post isolator system Ensure the slave isolator [S] is plumbed down-stream from its corresponding master isolator [M]. Optional self-sticking “J” clips are provided for neatly attaching the air hose to the tie-bars. Each post is shipped with a short section of tubing with a union coupler already attached to the input elbow. This “pigtail” segment should not be tampered with. Each pigtail contains a small, flow-restricting orifice to damp table motion and stabilizes the load....

Vibration Isolation Systems Setup Guide, 2017 System 1 Modular Post-Mount Supports Disconnecting Push red ring in Figure 7, Air tube connections Orifices Flow restricting orifices are critical to damping system motion. Orifices are located both inside the isolators and in the air tubing marked by a red ring as shown in figure above. Important Do not remove or change the location of these orifices without consulting TMC Ametek, Peabody, Massachusetts Page 8

Vibration Isolation Systems Setup Guide, 2017 System 1 Modular Post-Mount Supports TableTop Placement Step 3 Check to ensure assembled isolator frame is reasonably level. Adjust with floor shims if the floor is extremely uneven. Place the table top down on deflated isolators as shown in figure below. The top should be symmetric over the isolator frame. Height Control Valve with pressure gauge attached Figure 8, Typical 4 and 6 post assembled isolator frames Attach Horizontal Lever Arms Step 5 Locate the three height control valves mounted on isolators as typically shown in figure 8 above and...

System 1 Modular Post-Mount Supports Vibration Isolation Systems Setup Guide, 2017 Gimbal Piston Adjustment Step 15 Turn on the main air supply and set to 60-80 psi max. After a short delay, all the load disks should lift away from the clamp rings and the tabletop will then be floating. Check to see that the top of the piston and the top surface of the clamp ring are parallel as shown in figure below. Sliding or tapping load disk towards the low spot of the piston will correct any tilt. TableTop Load disk Piston 3/8 inch gap Reference note below Ensure two surface areas are parallel with each...
