MODEL 2088 ELECTRIC POWERED TURNTABLE Introduction

Archived 3/31/10

INTRODUCTION

The ETS-Lindgren Model 2088 EuroPro™ is an electric-powered variable-speed turntable platform system designed to be used with the Model 2090 Positioning Controller for EMI compliance testing. The Model 2088 is available in three diameters 1.23 meter,

1.53 meter and 2.03 meter. Designed for indoor use, the EuroPro turntable is perfect for installations in new or existing chambers where pit excavation is not an option or must be shallow.

The top is conductive with a continuous ground brush to better electrically couple the turntable to the ground plane. The ground brushes are attached directly to the top of the table and are in continuous contact with the floor-flange supplied with the ground ring option. The brushes point downward from the top of the table.

The drive motor and gearing are located beneath the platform. The Model 2088 Turntable utilizes a drive sprocket and sprocket drive with a gear reducer and electric motor. The top of the turntable is removable to provide easy access in the event that service is required. The electronics are located in a shielded enclosure. Signal I/O is via fiber-optic cable.

To prevent over-travel of the turntable in either direction of movement, “soft” electronic limits can be set using the Model 2090 Positioning Controller. Rotation speed can be varied from the front panel of the controller or through the IEEE-488 interface bus.

Standard Configuration MODEL 2088 ELECTRIC POWERED TURNTABLE

Archived 3/31/10

STANDARD CONFIGURATION

• Turntable Assembly

• Single-phase electric drive (208-230 VAC 50/60 Hz)

• Variable speed drive

• Conductive top

• Continuous rotation

• Ten meter fiber-optic control cables (standard)

MODEL 2088 OPTIONS

Model 2090 Positioning Controller: This controller provides control for two separate devices (EMCO towers and turntables) in any combination, plus the control of four auxiliary devices. The unit includes a GPIB bus and is compatible with most popular software. (Firmware revision 3.01 or higher required.)

Ground Plane Interface1: This interface is a square section of conductive flooring which has a pre-cut opening for the turntable. As a result, the difficult process of cutting a perfect diameter hole for the turntable is eliminated. The square edges of the interface connect to the chamber flooring using framing elements which provide a uniform and consistent clamping action. A pre-mounted ground ring is included with the interface. Together with the EuroPro’s continuous brush system, they provide continuity with the ground plane.

Shield Room Feed-Through: This option allows the customer to take the fiber-optic control cable from the control room to the shield room and still maintain shielding attenuation. The unit is made of brass for conductivity and provides attenuation of greater than 100 dB at 10 GHz. A single 22.25 mm (.875") hole is required to mount this option.

Additional Fiber Optic Cable: Additional lengths of fiber optic cable may be ordered.

European manufactured models include ground plane interface.

Turntable Installation Considerations MODEL 2088 ELECTRIC POWERED TURNTABLE

Archived 3/31/10

TURNTABLE INSTALLATION CONSIDERATIONS

Pre-planning is essential for a successful installation. Be sure to discuss your requirements with your sales representative and request dimensional drawings prior to construction of your site.

POWER AND SIGNAL LINES

Conduit

Power and signal line paths should be planned in advance. Conduit should be in place before pouring concrete or installing the ground plane. Be sure to consider the size of the cable bundle when selecting conduit diameter.

Electrical Considerations

A qualified and licensed electrical contractor should be used to install power lines, and the installation should comply with all applicable regulatory agencies. A dedicated circuit should be used, with the shortest distance possible between the power source and the turntable.

Access

An access area underneath the turntable is advisable for large diameter installations. A service switch should be installed to deactivate the turntable during service.

1. The turntable installation will vary based on the host location.

There are several installation options presented in some steps, please select the one that applies to your location.

2. Uncrate all parts. Check all parts for any shipping damage.

Ensure a clear area is available to assemble the turntable unit safely.

NOTE: Do not discard any packing material until the turntable is fully assembled.

3. Verify that that fiber optic cable is long enough to reach from

the turntable to the control room. When working around the table avoid stepping on the fiber optic connectors located at the relay box.

4. If the turntable is to be installed in a pit, check pit depth and

inside diameter and compare measurements with the drawings, for your turntable size, at the back of this manual.

The inner diameter of the receptacle pit should be as follows:

1.23 meter turntable = 50.44”

1.53 meter turntable = 62.25” a. If you have a paneled floor, did not purchase the integrated

ground plate interface option, and are installing the turntable into a pit in the ground plane a receptacle hole must be cut in the floor panels.

b. If you have purchased the Integrated Ground Plate Interface

option. It should be installed prior to lowering the turntable into place.

5. Remove the bolts which attach the top onto the turntable drive

assembly. Refer to the assembly drawing in the rear of this manual for more details.

CAUTION Lifting of the turntable assembly using a forklift or other lifting machinery should be performed by qualified personnel.

6. Using a forklift or other appropriate lifting device, place the

turntable bottom into position. The relay box with the fiber optic connectors should point in the direction that the fiber optic cable will be installed. This will reduce the chance of the cable being kinked or bent.

7. Position the table as close as possible to the center by

measuring from the bearing to the inner diameter of the raised floor. To be sure, measure in at least eight places and split the difference. Once you have found the center and are comfortable with the measurements, using a marker, mark around the perimeter of the table base. These marks may be used for reference if the assembly moves during placement of the floor shims or anchor plates. Also when positioning, attempt to make as many anchor holes miss the floor joint strips, as possible, if the table is being installed on a panel floor in a chamber.

8. Most 2088 models have floor anchor plates that will need to be

placed under the base unit. The 1.5 and 2.0 meter models also have an outer ring of floor plates to support additional casters. There are connector strips that will be placed between the base unit and the outer plates to ensure proper spacing. Please refer to the drawings at the back of this manual for proper floor plate placement. Using a pry bar, carefully lift the table and place plates under the anchor holes around the edge on the turntable base. If you are installing your turntable in a welded chamber with steel pit and steel raised floor please refer to step 12.

9. Use ½-13 x 5” square head set screws and ½-13 flange nuts to

hold the plates in place. Screw the plates to the floor using #14x1” #3 square socket flat head screws. Drill 1/8” pilot

Installation MODEL 2088 ELECTRIC POWERED TURNTABLE

holes for these screws and vacuum up shavings so that you have good contact with the floor. Continue mounting the rest of the plates.

10. Once all anchor plates are securely mounted, remove the ½-13

x 5” sets screws and then drill 27/64” pilot holes approximately ¾” deep into the paneled floor. Be careful not to penetrate the bottom skin of the panel. Vacuum out shavings and dust. Tap holes ½"-13 about ½" deep then install set screws back into the plate and floor. Do not drive the screws too far.

11. Now place plates at each caster as shown in the drawings at the

back of this manual. Screw plates down as mentioned above using ½-13 set screws and flange nuts. Once all plates have been secured to the floor it is time to level the table to the raised floor.

12. When mounting to a steel pit and steel raised floor you will not

need ¼” anchor/shim plates. You will need a ½-13 tap, 27/64” drill for tap, ½-13 x 5” square head set screw and flange nuts. Drill 27/64” dia. holes in the center hole of each group of 3 at the perimeter of the turntable base. (Model 2081-6x). Tap each hole as you drill it and then screw in ½-13 x 5” set screws so that the table does not move as you go around each location. Proceed with leveling instructions in step 13.

CAUTION: Before leveling make sure all ½-13 flange nuts are backed off all the way to avoid pulling plates off the floor.

13. Using a leveling instrument, (torpedo laser level or some other

device), raise the table until it is between 1/8” and 3/16” above the raised floor, this is just a rough finish height. Do not lower the other leveling screws on the casters until after the floor flange has been mounted. Once you have one screw secured on the floor and the table is level, snug up the remaining leveling screws by the anchor bolts and lock down the flange nut to hold the table in place while the turntable floor flange is being mounted.

RAISED PANEL FLOOR FLANGE INSTALLATION

The ground ring assembly includes a floor flange which interfaces with the brush ring located on the perimeter of the turntable. The floor flange provides constant electrical contact with the ground plane and is usually installed with the turntable.

Mounting methods vary according to user specifications. Clearance holes are provided, at evenly spaced intervals, along the outside perimeter of the ground ring as a means of attaching the ring to a customer supplied ground plane. These instructions cover installation for a paneled floor, please see the section on “Rolled Steel Flange Mounting in Concrete Pit” for further instructions if that is where your flange will be mounted.

For this step you will need a pipe clamp and three 3/8” allen wrenches or some other piece of material that is 3/8” diameter. You will also need a hand drill, 5/32” drill bit, #3 phillips drive bit, a small square, marker, and ¼”x 1-3/4” phillips flat head, TAPCON screws, and a hacksaw.

The turntables described in this manual each have two floor flange pieces. All of the flanges are cut oversize for bending purposes and the only one that will need to be cut is the last flange installed.

Using a pipe clamp and 3/8” allen wrenches or 3/8” pin, place a spacer between the turntable and flange starting in three places in the center or on the flange. Once there is tension on all three wrenches, drill a 5/32” hole through the counter-sunk holes in the floor flange. Drill completely through the panel and place screws into the holes. Continue working around the flange doing 2 or 3 holes at a time.

NOTE: It is very important that this 3/8” gap between turntable and floor flange be held as close as possible so that the grounding brushes seat properly. Also make sure that the flange ends are flush with each other.
