1.0 Introduction

The ETS-Lindgren Model 2181 Turntable is an electric-powered turntable
platform system designed for use with the Model 2090 Series Multi-Device
Positioning Controller for EMI compliance testing. The Model 2181 is designed
for indoor or outdoor use, and is available in 2-meter, 3-meter, 4-meter, and
5-meter sizes.

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.

All 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 the front panel of the Model 2090 controller or through
the IEEE-488 interface bus.

Model 2181 Standard Configuration

TURNTABLE ASSEMBLY

Featuring continuous or non-continuous operation, the turntable assembly
includes:

• 3-phase electric motor unit

• Heavy-duty variable speed drive system

• Conductive sectional top for easy service access

• Convenient rotational limit adjust switches

Introduction | 7

• Limit override feature

• Ground ring assembly with ground brush and floor flange

• 10-meter fiber optic control cables

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.

SHIELD ROOM FEED-THROUGH

The 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 (.875-in) hole is required for mounting.

operation.

The Model 2090 Series Multi-Device Positioning Controller provides control for
two separate devices, such as ETS-Lindgren towers and turntables, plus the
control of four auxiliary devices. The Model 2090 controller includes a GPIB bus
and is compatible with most popular software, and electronically controls speed
adjustment through the GPIB interface or front panel.

INFRARED REMOTE CONTROLLER

The Model 2181 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).

8 | Introduction

The IR remote communicates with an infrared receiver in the Model 2181
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.

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.

4.0 Turntable Installation Considerations

Before assembling, installing, or connecting any components,
follow the safety information in the ETS-Lindgren
Product Information Bulletin included with your shipment.

Pre-planning is essential for a successful installation. Discuss your requirements
will your sales representative and request dimensional drawings prior to site
construction.

Before You Begin—Precautions

Read this manual completely before starting installation. This
equipment should be installed and operated only by qualified
personnel.

Do not attempt to service unless qualified to do so. As with any
electrical equipment, make sure unit electrical power has been
disconnected and secured when performing scheduled
maintenance or adjustments.

WARRAN TY

Do not make any modifications to this unit without consulting
the factory directly.

Regularly inspect all equipment and conduct scheduled
maintenance in accordance with the factory recommendations
provided.

Only use replacement parts and fasteners ordered directly from
the factory.

Stay clear of all moving components on this equipment.

Do not operate turntable while someone is physically on the
turntable top.

Turntable Installation Considerations | 15

Do not, at any time, place hands or feet in the vicinity of the
drive pinion on the turntable.

Power and Signal Lines

CONDUIT

Power and signal line paths should be planned in advance. Con duit should be in
place before pouring concrete or installing the ground plane. Consider the size of
the cable bundle when selecting conduit diameter.

ELECTRICAL CONSIDERATIONS

A qualified and licensed electrical contractor should 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 beneath 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 15 cm (6 in) must be installed to provide proper
drainage during rainstorms and other moisture-collecting situations.

COLD CLIMATE CONDITIONING

The oil used in the gear assemblies will congeal at 2 degrees C (28 degrees F).
Turntables operated in these temperatures should include a heat source or
dehumidifier, or both.

16 | Turntable Installation Considerations

5.0 Electrical Installation

Model 2181 Electrical Installation

The Model 2181 Turntable is configured to operate using 200-230 VAC, single
phase, 50/60 Hz service. It is recommended to operate at this voltage level to
reduce the surge currents necessary to power an electric motor.

1. The branch circuit supplying power to the motor base should be

protected from excess current according to local electrical codes. An
integral circuit breaker is mounted inside the main bearing on one of the
bearing support blocks. The circuit breaker is specifically designed for
the inductive load presented by the electric motor.

Before assembling, installing, or connecting any components,
follow the safety information in the ETS-Lindgren
Product Information Bulletin included with your shipment.

Electrical installation must be performed by a qualified
electrician, and in accordance with local and national electrical
standards.

2. Make sure the conductor size is adequate for the motor load and the

distance from the mains source. Improperly sized conductors will lead to
a high voltage drop in the power conductors and cause reduced starting
torque and premature motor failure.

3. The motor base assembly is provided with a non-terminated flexible

conduit with input power leads exposed. The flexible conduit is to be
terminated into a junction box fitted on or near the motor base. Terminate
the power leads of the motor base assembly according to local electrical
code requirements. Following is the conductor color code:

Brown: AC high

Blue: AC neutral

Green/Yellow: Protective earth/safety ground

Connect the fiber optic control cable and install the power connection according
to local electrical code. See the Model 2090 Series Multi-Device Controller
Manual for information on connecting the fiber optic cable. After the fiber optic
cable is installed, secure it with a wire tie to one of the leveling screws.

Electrical Installation | 17

To feed the fiber optic connectors through the waveguide in a chamber, it may be
necessary to remove part of the protective sheath. This removal allows the
connectors to fit through the hole without excessively bending the fiber optic
cable. Find and mark the spot where you will need to remove the sheath. Use a
sharp knife to carefully cut around the outside of the sheath at each end of the
defined area. Cut very lightly to avoid cutting into the fiber optic cables, and then
bend the sheath back and forth to expose the fiber optic cables.

Next, make a cut down the length of sheath area, being careful not to cut into
fiber optic cable. Inside the sheath are two pieces of white string. Find the string
and use it to split the sheath open. Insert the fiber optic cable into the waveguide.

Connecting the Model 2090 Controller

Any combination of primary devices (towers, turntables, reverberation paddles,
MAPS, and so on) can be connected to the two device interface ports located on
the rear panel of the Model 2090 Series Multi-Device Positioning Controller. For
easy set up of an EMC facility, it is recommended that the turntable be connected
to the Device 2 port. The default settings for the controller are for a tower
connected to the Device 1 port and a turntable connected to the Device 2 port.

Primary device connection is accomplished with a dual fiber optic cable included
with the device. This cable terminates into two ST connectors that are identical at
both ends. The cable is symmetrical, so either end can be connected to the
controller. A fiber optic cable connected to the IN port of a device should be
connected to the primary OUT port of the motor base at the other end. Similarly,
a fiber optic cable connected to the OUT port of the device should be connected
to the primary IN port of the motor base at the other end. Older motor base
designs have only one fiber optic connector pair, but the newer motor base
interface provides a secondary interface reserved for future expansion.

Fiber optic cabling for each device should not hang unsupported from the rear
panel of the controller. The fibers and connectors are easily broken if twisted or
bent. Keep the fiber optic cables as straight as possible from the connector to
the protective sheath.

Using the Model 2090 controller or optional Infrared Remote Controller
(IR remote), rotate the motor base shaft to verify proper operation. Run the
motor base down to the lower limit counterclockwise, and then back it off from
the lower limit a small amount. The previous step will help when it is time to set
the rotation limits for the turntable.

The soft rotational limits in the Model 2090 controller must be
set. Make sure the travel limit settings will not cause damage to
user installed cables and equipment mounted on the table.

18 | Electrical Installation

6.0 Assembly and Installation

Assembly and Installation | 19

4. The drawings in the back pocket of this manual show the placement of

floor plates and leveling screws to anchor and level the turntable. Anchor
the turntable through the attachment holes using the concrete expansion
bolts provided. After installing the floor plates and leveling screws, level
the entire turntable by adjusting all the leveling screws between and
under the casters, and in the center section of the turntable.

5. Tighten all lock nuts accompanying the leveling screws to lock the height

of the turntable into place.

6. Connect the fiber optic control cable and install the power connection

according to local electrical code. The standard power configuration is
230 VAC 50/60 Hz.

Electrical connection is subject to local electrical codes, and
should only be performed by a qualified electrician.

Keep all body parts away from the drive pinion when the
turntable is energized.

7. Follow the instructions in the next section, Floor Flange Installation in a

Paneled Floor, to install the ground ring assembly.

8. Reinstall the top section removed in step 3 of these instructions.

Floor Flange Installation in a Paneled Floor

A 2-meter Model 2181 Turntable is depicted in the following illustrations.

20 | Assembly and Installation

When the turntable is positioned as close as possible to the center, attach the
measuring bar to the brass spacers mounted onto the bearing. Appropriate
hole-mount locations correspond to the size of the turntable. Rotate the bearing
and make sure approximately

7/8-in to 1-in spacing exists between the edge of

the outer measuring bar and the diameter of hole cut into the pit. Adjust as
required.

The ground ring assembly includes a floor flange with a mounted brush ring that
interfaces with the contact ring mounted beneath the turntable top. The floor
flange provides constant electrical contact with the ground plane.

Mounting methods vary according to user specifications. Clearance holes are
provided at evenly spaced intervals along the outside perimeter of the floor
flange to attach to a customer supplied ground plane. These instructions
describe installation for a paneled floor. For concrete pit mounting instructions
see Floor Flange Installation in Concrete Pit on page 23.

Installing the ground ring assembly requires these tools:

• 1/4-in spacers (3)

• Hand drill

• 5/32-in drill bit

• #3 Phillips drive bit

• Small square

• #14 x 1 wood/metal screws

Assembly and Installation | 21

The turntables have a quantity of floor flange pieces depending on the size of the
turntable. All flanges are pre-cut at the factory for a drop-in fit.

A 2-meter Model 2181 is depicted in the following. The turntable top is shown
as a partial cut-away to provide a view of internal components.

1. Lay the floor flange into the opening of the raised floor and push outward

to the diameter of the opening.

2. Attach the turntable top onto the center bearing with the hardware

provided.

3. Using a pipe clamp and 1/4-in Allen wrenches or 1/4-in pin, place a

spacer between the turntable and floor flange starting in three places in
the center or on the flange.

4. Once tension is placed on all three wrenches, drill a 5/32-in hole through

the counter-sunk holes in the floor flange. Drill completely through the
panel and place screws into the holes.

5. Continue working around the floor flange, completing two or three holes

at a time.

Make sure that a 1/4-in gap between the turntable top and the mounted brush
ring be held as close as possible so that the grounding brushes seat properly.
Also, make sure the flange ends are flush with each other.

22 | Assembly and Installation

6. Continue mounting until all screws are installed. Some screws may fall

between the floor panel joints. Try to position the flanges, making sure as
few screws hit these points as possible, and making sure that the first or
last hole in the flange is not too close to one of these joints. Trim the top
floor joint strips to fit up against the flange.

Floor Flange Installation in a Concrete Pit

Installing in a concrete pit is the same as a paneled floor, with the exception of
the mounting hardware. Instead of the #14 x 1-in square socket flat head screws,
use 1/4 x 1-3/4-in Phillips flat head concrete anchors.

These tools are required for the next stage of installation:

• 1/2-in hammer drill

• 3/16 x 3 1/2-in hammer drill bit, at minimum

• Vacuum to clean inside the drilled holes for maximum thread

engagement

When drilling holes, be aware of buried conduit and pit drainpipes. Drill 3/16-in

between 395 and 415 degrees.

If non-continuous operation is desired, properly set the soft limits in the
controller.

To set the CCW rotational limit for the turntable:

1. Press the DOWN/CCW key under LIMIT. The indicator above the key will

illuminate.

2. Set the limit by pressing the INCRM and DECRM keys under LIMIT until

the desired limit is shown on the display.

3. Press the ENTER key.

To set the CW rotational limit for the turntable:

1. Press the UP/CW key under LIMIT. The indicator above the key will

illuminate.

2. Set the limit by pressing the INCRM and DECRM keys under LIMIT until

the desired limit is shown on the display.

3. Press the ENTER key.

Make sure the current travel limit settings will not cause damage
to existing cables and equipment located beneath the turntable.

If continuous operation is desired, the Model 2090 controller permits easy
configuration to this type of operation from the front panel or through the
IEEE-488 interface bus. For more information, see the Model 2090 Series
Multi-Device Controller Manual. The limit pins should also be removed from the
turntable top to allow for continuous operation.

Operation | 27

Turntable Encoder Calibration

Parameter C, the encoder calibration parameter, calibrates the encoder counts to
the rotation of the turntable. For the Model 2181, parameter C must be set to

3660. This setting is used to convert the encoder count values returned from a

motor base into the corresponding centimeter or degree position reading. For
turntables, this represents the number of encoder counts per revolution.

If the given value does not work correctly, the encoder calibration value can be
determined using the following procedure:

1. Set the encoder calibration value to 3600.

2. Make sure the turntable is positioned to allow more than a full revolution

of travel in the CW direction. Use the STEP keys to run the turntable CW
a few degrees to remove any play in the turntable.

3. Using masking tape, mark the current location of the turntable against

the ground ring, and set the current position reading to 000.0.

4. Using the STEP keys, rotate the turntable CW until it is again aligned

with the mark on the ground ring. For best results, the last motion should
always be in the CW direction to account for any play in the gearing
between the motor and encoder.

5. Record the reading of the display, ignoring the decimal point. For

example, 360.0 would be 3600. This is the encoder calibration value.

If the value is below 3600, the resolution of the encoder is low and the controller
will not provide 0.1-degree resolution, even though the display shows that digit.
If the value is past 9999, the encoder has too many counts per meter and the
controller cannot correct for it. In this case, contact ETS-Lindgren for
assistance.

6. Enter the encoder calibration value and reset the limits and position

information.

7. Test the turntable by moving it a complete revolution and comparing the

alignment marks. It may be necessary to adjust the encoder calibration
value up or down slightly depending on the result.

When scanning between limits, it is not uncommon to have a small discrepancy
between the absolute position of the table and the display on the controller.
This is because reversing the direction of rotation reverses any gear play
between the encoder and the table top, allowing that play to be visible in the
positioning accuracy.

28 | Operation

TURNTABLE CALIBRATION EXAMPLE

• The turntable is set at the 0 degree position. A piece of tape is placed on the
edge of the turntable to line up with the edge of the gearbox cover. The
turntable is stopped when the tape travels exactly 360 degrees around. The
display on the controller now reads 356.3 degrees, which is recorded.

• The table is rotated CCW back to zero. The parameter button is set on the
C setting. The C digits display 3430. A new C setting is now calculated:

New C = (356.3 / 360) x 3430 = 3395 (rounded)

• Decrement the C parameter to 3395 and press ENTER. Press the
current position button to get back to operation mode.

• The table is rotated from 0 to 360 and the mark is now within one degree of
being one full turntable revolution. Calibration is complete.

Changing Rotation Speed

The Model 2181 is equipped with a variable speed drive. Firmware revisio n 3.11
or higher must be installed in the Model 2090 controller for proper operation of
the Model 2181. The revision level is displayed on the front panel display during
startup of the Model 2090 controller. If the controller does not have this revision
or a later revision installed, contact ETS-Lindgren for an upgrade.

To select one of the four speeds, use the POLAR/SPEED button to toggle
through the speed options. It is necessary to set the controller parameters to
configure the controller to properly control the motor base. See the
Model 2090 Series Multi-Device Controller Manual for information on setting the
parameters.

Variable Speed Settings

The Model 2090 controller parameters S1-S8 control the variable speed settings
for the turntable. These parameters are the continuous variable speed settings
for each of the four speed selections described in the next section,
Speed Selection. Each of these parameters can be set to any value from 1 to
255, with the resulting turntable speed being roughly an S/255 fraction of the
maximum speed. For any variable speed drive, there is a minimum speed at
which the motor will operate. For the Model 2181 this minimum speed setting is
between 30 and 75, and should correspond to a value of 0.5 RPM or less. Below
this setting, the motor will not be able to cause rotation, but will be active until a

Motor Not Moving error (E002) occurs.

Operation | 29

Do not operate the turntable in a stalled condition. Doing so may
cause damage to the drive unit and will void your warranty.
Always make sure that the minimum speed setting specified in
the S1-S8 parameters is above the minimum value at which your
turntable will rotate under normal load.

Speed Selection

For the variable speed turntable, the Polarization/Flotation button provides the
ability to cycle between eight preset speeds. For each press of the button, the
turntable will change to the next speed setting. The polarization LEDs will light to
indicate the speed selection as shown in the following:

Speed 1: Both off
Speed 2: Top on, bottom off
Speed 3: Top off, bottom on

Each speed setting has an individual overshoot compensation value to provide
overshoot correction.

GPIB Commands

The following GPIB commands have been added or modified:

S?: Query speed selection

Speed 4: Both on
Speed 5: Both off
Speed 6: Top on, bottom off
