1.0 Introduction
The ETS-Lindgren Model 2187 Turntable is an electric-powered turntable
platform system designed for use with the Model 2090 Multi-Device Controller (or
next generation ETS-Lindgren controller, if applicable) for EMI compliance
testing. The Model 2187 is available in 2.03-meter and 3.03-meter sizes, both
designed for indoor or outdoor use.
The top of the turntable is conductive with a continuous ground brush to
electrically couple it to the ground plane. The ground brushes are attached
directly to the chamber floor by the floor flange, and are in continuous contact
with the turntable top. The brushes point downward from the floor flange.
Both models utilize a pinion and gear drive with a gear reducer and electric motor
located beneath the platform. The bearing on which the turntable rotates has the
drive teeth cut directly on the outside and will easily support most Equipment
Under Test (EUT). Support for the turntable includes casters that aid in the
support of cantilevered loads on the outside of the turntable.
The turntable top is sectional to provide easy access if service is required. On
standard models, a 15-cm hole is provided in the center of the turntable to
accommodate customer supplied cabling to and from the EUT.
To prevent over-travel of the turntable in either direction of movement, hard limits
are provided in the form of pins that actuate switches located below the tabletop.
These pins allow limits to be set and allow as much as two full rotations. Rotation
speed can be varied from a controller (not included) or through the IEEE-488
interface bus.
Standard Configuration
TURNTABLE ASSEMBLY
Featuring continuous or non-continuous operation, the turntable assembly
includes:
• 230 VAC electric motor unit
• Convenient rotational limit adjust switches
• Ground ring assembly with ground brush and floor flange
• 10-meter fiber optic cable
Additionally, the turntable is infrared compatible, and can be used with an
optional ETS-Lindgren Infrared Remote Controller (IR remote). For more
information on using an IR remote, see Infrared Remote Controller on page 8.
Introduction | 7
SHIELD ROOM FEED-THROUGH
Routes the fiber optic control cable from the control room to the shield room,
maintaining satisfactory 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 (0.875-in) hole is required for mounting.
Optional Items
INFRARED REMOTE CONTROLLER
The Model 2187 is infrared compatible, and can be used with a universal remote
control programmed to a specific protocol, such as the ETS-Lindgren Infrared
Remote Controller (IR remote).
The IR remote communicates with an infrared receiver in the Model 2187
motor base through an IR repeater installed in the floor near the turntable. See
IR Repeater Installation on page 23 for instructions on installing an IR repeater.
SLIP RING
Allows continuous rotation of the turntable through the latest technology in
mercury slip rings, and either Schuko or NEMA connectors can be ordered with
the slip ring. The current rating for the standard electrical assembly is
20 amperes. Contact ETS-Lindgren for custom requirements on slip rings.
8 | Introduction
EUT POWER OUTLETS
Receptacles are usually mounted on the base of the turntable at the center axis
point. These receptacles can be custom mounted, flush with the tabletop on
some turntables. Contact ETS-Lindgren for information.
MOUNTED LINE IMPEDANCE STABILIZATION NETWORK
A Line Impedance Stabilization Network (LISN) can be mounted to the underside
of some turntables. This option is only practical on larger turntables with sufficient
clearance.
ADDITIONAL FIBER OPTIC CABLES
Additional lengths of fiber optic cable may be ordered.

2.0 Maintenance
WARRANT Y
Before performing any maintenance, follow the safety
information in the ETS-Lindgren Product Information
Bulletin included with your shipment.
Regularly inspect all equipment and conduct scheduled
maintenance in accordance with the factory recommendations
provided.
BEFORE SERVICING: CONTACT ETS-LINDGREN
(+1.512.531.6400)—Servicing or modifying the unit without
ETS-Lindgren authorization may void your warranty. If an
attempt to service the unit must be made, disconnect all
electrical power prior to beginning. Voltages exist at many points
within the instrument that could, if contacted, cause personal
injury. Only trained service personnel should perform
adjustments and/or service procedures upon this instrument.
Capacitors inside this instrument may still be charged even
when the instrument is disconnected from the power source.
Recommended Maintenance Schedule
Regular maintenance will prolong the effective operation and reliability of your
turntable. Follow the recommended schedule for 6-month and 12-month service.
Do not perform maintenance while the turntable is operating.
6-MONTH SERVICE
• Lubricate the casters with good quality bearing grease.
• Check the gearbox for fluid leakage. A collection of slight film is normal, but
puddles of fluid are not normal. The gearbox is lubricated and sealed at the
factory. Under normal conditions, the gearbox should not require servicing
during its life.
