REV C – PN 399253
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.

REV C – PN 399253
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.
1European manufactured models include ground plane interface.

REV C – PN 399253
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

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.
Archived 3/31/10

Installation MODEL 2088 ELECTRIC POWERED TURNTABLE

REV C – PN 399253
Typically the last flange will be too long. Turn the flange upside
down, butt one end to the other and evenly mark off with the other
end and trim to fit. Do not cut too much off. It is preferable to not
have more than 1/16" gap between the butt joint when finished.
Continue mounting as stated above until all screws have been
installed. Some screws may fall between the floor panel joints.
Try to position the flanges ensuring 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. Also the top floor joint strips
will need to be trimmed to fit up against the flange.
ROLLED STEEL FLANGE MOUNTING IN
CONCRETE PIT
Mounting to concrete is the same with the exception of the
mounting hardware. You should have ½-13 wedge type concrete
anchors. Instead of the #14 x 1” square socket flat head screws,
you will use 1/4 x 1-3/4. Phillips flat head TAPCON screws.
You will need a ½” hammer drill with a ½” x 12” hammer drill bit
and a 3/16 x 6” hammer drill bit. Instead of the 1/4 x 1-3/4”
tapcons, you will need ¼-20 x 1” phillips flat head thread rolling
screws for mounting the flange to the rolled steel flange. The drill
hole size for ¼-20 x 1” thread rolling screws is .238 - .242 (B or C
drill). You will also want a small vacuum to clean up concrete
dust so that it does not get into the screw threads making them hard
to screw in.
NOTE: When drilling holes, watch out for buried conduit and pit
drain pipes. Also drill ½” hole as deep as you can. Drill 3/16”
holes about 3 to 4 inches deep.
INSTALLATION OF STAINLESS STEEL WEAR
STRIP
It is very important that the floor around the turntable pit is level
all the way around. If it is not, it will make the installation of the
wear strip very difficult. For this step you will typically need eight
small 1-1/2” C-clamps , 6-32x 3/8” thread rolling screws, a hand
Archived 3/31/10

MODEL 2088 ELECTRIC POWERED TURNTABLE Installation

REV C – PN 399253
drill, 0.120 dia. drill bits, a #2 phillips bit, and some cutting oil.
Start the strip 1/8" below the surface of the flange at the end with
the hole closest to the end of the strip. Also start with the first 2
holes in strip in between the casters. Place a clamp about 2” on
either side of the hole on the strip in 4 places and then transfer drill
0.120 dia. holes into the aluminum floor flange and then screw in
the 6-32 x 3/8” thread rolling screws.
NOTE: Some of the pre-drilled holes in the strip will be in the path
of a caster. For these holes, casters will need to be removed by
taking out the center axle of the caster. Be careful not to lose any
washers or allow the washers to fall out.
NOTE: Be careful not to bend the stainless steel strip, this will
make it difficult to install properly. Do not let the stainless steel
strip come up above the top of floor flange since it may bend when
something heavy is rolled over it. It may be beneficial to be
slightly below the surface of the flange.
Continue installation around the turntable with the wear strip.
When you get to the end, you will need to cut the strip to length.
Let the strip overlap the fixed end, and using a square, mark a line
even with the fixed end. The gap of the 2 joints should be less than
1/16”. Deburr the cut. You will need to drill the last hole to match
the spacing on the other end of the wear strip.
GREASING CASTERS & BEARINGS
Using a synthetic grease, grease all casters. Mobil 1 synthetic is
recommended, do not use a lithium grease.
NOTE: Some casters may not have grease fittings. These will be
sealed bearings and will not require grease.
FINAL LEVELING OF TABLE
Lower all ½-13 leveling screws. Once the table is in place with the
floor flange and wear strip mounted, install all remaining screws
for the spacer plates and tighten. Once this is done, place shim
plates in the center of the turntable and insert leveling screws to

support the center. When you are satisfied that the turntable is
level, tighten all lock-nuts accompanying the leveling screws to
lock the height of the turntable into place. Install the remaining top
sections.

ELECTRICAL INSTALLATION
CAUTION: Electrical connection should only be performed by a
qualified electrician and subject to local electrical codes.
The Model 2088 is designed to operate using 208-230 VAC single-
phase 50 or 60Hz power.
The branch circuit supplying power to the motor base should be
protected from excess current according to local electrical codes.
ETS-Lindgren has provided integral circuit protection in the motor
base assembly.
Check that 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.
The motor base assembly is provided with an IEC-320 power inlet
for connecting to the mains. Prior to servicing the turntable or the
turntable motor base, remove the power connection for safety.
Connect the fiber-optic control cable and install the power
connection per local electrical code. Please refer to the Model 2090
Positioning Controller manual for instructions 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.
In order to feed the fiber optic connectors through the waveguide
in a chamber it may be necessary to remove part of the protective
sheath. The removal of a portion of the sheath will allow the
connectors to fit through the hole without bending or kinking the
fiber optic cable excessively. Find the spot in which you will need
to remove the sheath and mark. A very sharp knife is needed to
make the splice. Being very careful, cut around the outside of the
sheath at each end of the area needing to be cut, cut very lightly so
as to not cut into the fiber cables. You should then be able to bend
the sheath back and forth until you can see the fiber cables.

Next you will need to make a cut down the length of sheath area,
being careful not to cut into fiber cable. You should see two
pieces of white string inside the sheath. Find the string and use it
to split the sheath open. Now insert into the waveguide.

OPERATION
Please refer to the Model 2090 Positioning Controller manual if
you are unfamiliar with the operation of the unit. A 2090 manual is
included with each 2090 shipment and is also available for
download from our website www.ets-lindgren.com .
With the assembly complete the Model 2090 controller will need
to be connected to the unit and power applied to both the motor
base and controller in order to continue. Refer to the electrical
installation section if you have questions about how to connect the
fiber optic cables.
Using the Model 2090 Positioning Controller check the CW and
CCW rotation in both directions by a few degrees. The position in
degrees increases (+) in the CW direction and decreases (-) in
CCW direction.
The turntable is calibrated at the factory to read out 360 degrees (+
or - 1 degree) for one complete revolution. If the table is not within
this accuracy, the unit can be re-calibrated per the instructions in
the “Turntable Encoder Calibration” section.
APPLICATION OF CONDUCTIVE GREASE
Before placing an EUT on the turntable or configuring it for use.
Using the turntable controller, position the table to the 0 degrees
position. Make a straight line from the table to the flange to verify
the encoder count and positioning of table. Then start the table in
scan mode. Using a syringe, squeeze the contents of one tube of
GC Electronics conductive grease into the barrel. While table is
rotating slowly apply grease to the grounding brushes. Apply one
tube per meter size of the diameter of the table. Run table for
approximately 1 hour to validate proper operation and allow
sufficient lubrication of moving parts.

CONTROLLER CONFIGURATION
PARAMETERS
To edit a configuration parameter, press the PARAM key to
display the current parameter. Pressing the PARAM key
repeatedly will scroll down through the parameter list, showing
each parameter in turn. While viewing a parameter, the STEP
keys (INC/DEC) may be used to scroll up or down the parameter
list. This reduces the effort necessary to scan through a long
parameter list using the PARAM key. Pressing any of the
LIMIT/POSITION selection keys will return the display to that
selection. Pressing any of the remaining motion keys will return
the display to the current position and execute that motion.
Pressing the PARAM key again will return to the last displayed
parameter in the list, allowing easy transition between parameter
adjustment and device operation.
Once the desired limit, position or parameter is visible in the
display window, pressing INCRM, DECRM, or ENTER will
toggle into edit mode. The lowest adjustable digit will flash on
and off. Pressing the LOCAL key for that device will switch the
flashing digit to the next higher digit. In this way, it is possible to
rapidly adjust any digit of a multi-digit parameter or limit.
SETTING TRAVEL LIMITS
The Model 2088 is not fitted with mechanically actuated or “hard”
limit switches. It is essential that the user properly set the “soft”
limits in the Model 2090 Controller should non-continuous
operation be desired.
To set the counterclockwise rotational limit for the turntable, press
the DOWN/CCW key under LIMIT. The indicator above this key
will light. Set the limit by pressing the INCRM and DECRM keys
under LIMIT until the desired limit is shown on the display. Then,
press the ENTER key. To set the clockwise rotational limit for the
turntable press the UP/CW key under LIMIT. The indicator light
above this key will light. Set the limit by pressing the INCRM and
