MODEL 2081 TURNTABLE SERIES Introduction

REV D – PN 399212

INTRODUCTION

The ETS-Lindgren Model 2081 is an electric powered turntable

platform system designed to be used with the Model 2090

Positioning Controller for EMI compliance testing. Two meter and

larger tables utilize a pinion and gear drive with a gear reducer and

electric motor. The conductive metal top is outfitted with a

continuous ground brush to electrically couple the turntable to the

ground plane. The drive motor and gearing are located beneath the

platform. The sectional turntable top provides easy access in the

event that service is required. A shielded enclosure contains the

electronics for the system. Signal I/O from the turntable to the

Model 2090 controller is via fiber optic cable.

The bearing on which the turntable rotates has the drive teeth cut

directly on the outside and will easily support most heavily

weighed equipment under test (EUT). Casters underneath the table

surface aid in the support of a cantilevered load. Leveling screws

are located at each caster, between the casters and in the center

section of the assembly for ease in matching height on an uneven

ground plane.

To prevent over-travel of the turntable in either direction of

movement, mechanical limits can be set using dial knobs on the

outside of the encoder enclosure located in the center of the main

pivot bearing. The knobs can be accessed by removing the center

section of the turntable. Soft limits can be set within the

mechanical limits, using the Model 2090 Positioning Controller.

Ground brushes attached directly to the top of the table are in

continual contact with the floor flange supplied with the ground

ring option. The brushes point downward from the top of the table.

To extend the life of the ground brush, a one-piece stainless steel

liner is attached to the inside edge of the stationary floor flange.

MODEL 2081 TURNTABLE SERIES Options

REV D – PN 399212

OPTIONS

Model 2090 Positioning Controller: This controller provides

control for two separate devices (towers and turntables) in any

combination, plus the control of four auxiliary devices via a fiber

optic interface. The unit includes a GPIB connection and is

compatible with most popular EMI measurement software.

Hand Control Unit: This sturdy, hand-held controller will allow

the user to manually operate the table remotely and independently

from the Model 2090 Positioning Controller. This controller

attaches conveniently to the electrical enclosure located on the

base of the turntable. Functions include: Clockwise (CW),

Counterclockwise (CCW) and Hand/Main Control selection.

Slip Ring: This option allows continuous rotation of the turntable

through the use of the latest technology in mercury slip-rings. The

slip ring option is typically supplied with Schuko or NEMA

connectors. Specify part #103441 for NEMA connectors, and part

#103351 for Schuko connectors. The amperage rating for the

standard electrical assembly is 20 amps. Consult the factory for all

custom requirements on slip-rings.

Shield Room Feed-through: This option allows the customer to

take the fiber optic control cable from the control room to the

shield room while maintaining shielding attenuation. The unit is

made of brass for conductivity and provides attenuation of greater

that 100 dB at 10 GHz. A single 22.25 mm (.875 inch) hole is

required to mount this option.

Additional Fiber Optic Cable: Various lengths of fiber optic

cable are available by customer order. The standard length

provided is 10 m (32.8 ft).

Variable Speed Drive: An optional variable speed drive package

is available with the Model 2081 Turntable. Speed adjustment is

electronically controlled by the Model 2090 via the front panel or

through the GPIB interface.

Precautions MODEL 2081 TURNTABLE SERIES

REV D – PN 399212

EUT Power Outlets: Receptacles are usually mounted on the base

of the turntable at its center axis point. These receptacles can be

custom mounted, flush with the tabletop on some turntables.

Consult the factory for more details.

Mounted LISNs: LISNs can be mounted to the underside of some

turntables. This option is only practical on larger turntables with

sufficient clearance.

PRECAUTIONS

Read this manual completely before starting installation. This

equipment should be installed and operated only by qualified

personnel.

Ensure correct voltage setting is selected on the Motor Base unit

(when applicable).

The fiber optic cable must be looped through the “P” clip installed

on the front panel of the motor base. Failure to do so will increase

the chance of the cable being accidentally pulled, thus breaking the

fiber optic connectors.

Do not attempt to service unless qualified to do so. As with any

electrical equipment, ensure unit electrical power has been

disconnected and secured when performing scheduled maintenance

or adjustments.

Do not make any modifications to this unit without consulting the

factory directly.

Stay clear of all moving components on this equipment.

Do not, at any time, place hands or feet in the vicinity of the drive

pinion on the turntable.

Do not operate the turntable while someone is physically on the

turntable top.

MODEL 2081 TURNTABLE SERIES Precautions

REV D – PN 399212

Regularly inspect the equipment for loose fasteners and wear.

Conduct scheduled maintenance in accordance with the factory

recommendations provided.

Only use replacement parts and fasteners ordered directly from the

factory or specified by ETS-Lindgren.

The access plate(s) above the pinion gear should remain firmly

attached with the screws provided at all times. When the plate is

removed for servicing, the electrical breaker located on the

electrical control enclosure should be in the OFF position.

Turntable Installation Considerations MODEL 2081 TURNTABLE SERIES

REV D – PN 399212

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.

OUTDOOR INSTALLATIONS

Drainage

A centerline drain of at least 15cm (6in) must be installed to

provide proper drainage during rain storms, etc.

Cold Climate Conditioning

Oil used in the gear assemblies will congeal at 2oC (28oF).

Turntables operated in these temperatures should include a heat

source and/or dehumidifier.
