MODEL 2065 LOPRO TURNTABLE Introduction
Archived 3/18/10
INTRODUCTION
The Model 2065 is an electric-powered turntable platform system designed to be used with the Model 2090 Positioning Controller for EMI compliance testing. The Model 2065 Turntable is a low­profile design which is constructed of PVC plate with a textured ABS top and other non-metallic components. The 1.2 meter diameter turntable is provided as an easily assembled system which can be disassembled for service or to be moved. The mechanical assembly, motor drive unit, and shaft kit (optional), comprise the three basic subassemblies of the turntable.
The mechanical assembly is shipped assembled with the top, base, gear box, support bearings and drive belt included. The bearings on which the table rotates are integral to the top and bottom of the turntable. Three independent bearing races provide support for the inner and outer portions of the turntable top. These bearings are of a completely non-metallic construction. There are four keepers located on the outside of the turntable top. These keepers prohibit the bearings from shifting out of position during shipment. When the user has the table set in place and is ready to begin testing, these should be removed.
The motor drive, encoder and limit switch assemblies are located in a shielded enclosure with state of the art I/O provided via a fiber optic interface. The motor drive is coupled to the drive shaft with a flexible hose coupling. The other end of the shaft connects to the turntable gear box with a keyed coupling that clamps between the two shafts. The shaft assembly transmits torque from the motor drive to the gear box at the table. The drive belt, which runs around the underside of the turntable at its perimeter, is driven by a pulley in the gear box.
To limit over-travel of the turntable in either direction of movement, fixed mechanical limits are installed in the motor base enclosure. The primary means of limiting the turntable’s rotation are the soft (electrical) limits which are set on the front panel of the Model 2090 Positioning Controller. These soft limits should be set

Archived 3/18/10
within the mechanical limits. The mechanical limits are secondary and a safety stop to limit the turntable’s total rotation.
Overshoot of the turntable’s rotation is limited by an electric brake which is directly attached to the drive motor. The Model 2090 Positioning Controller compensates for any remaining overshoot by applying an overshoot compensation routine which is accomplished automatically without any user input.

ELECTRICAL INSTALLATION
CAUTION It is important that this electrical installation
procedure be performed by a qualified electrician, in accordance with local and national electrical standards prior to energizing the unit.
CAUTION Ensure power is OFF and secured before proceeding
further. The voltage select switch on the Motor Base Unit must be set to the proper mains voltage before power is applied to the unit.
The Motor Base Unit of the Model 2065 Low Profile Turntable allows for the selection of either 115 or 230 VAC mains input voltage. This selection should be made during installation and prior to connecting the Motor Base Unit to the power mains.
On the front of the enclosure for the Motor Base Unit, locate the voltage select switch which is marked for 115 and 230. Switch to the appropriate position which corresponds to the mains voltage to be applied. This switch provides a means of selecting the voltage to be applied to the drive motor, electric brake and internal power supply.
Determine the mains voltage to be applied to the Motor Base Unit. The branch circuit supplying power to the motor base should be protected from excess current according to local electrical codes. Check that the conductor size is adequate for the motor load with respect to 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. This condition could lead to premature motor failure.
© EMC TEST SYSTEMS, L.P. – APRIL 2002 7 REV F – PN 399230
CAUTION Keep all body parts away from the drive gears and
drive belt when the turntable is energized. Do not operate the turntable with the protective guards removed.

CONNECTING THE MODEL 2090 POSITIONING CONTROLLER
Any combination of primary devices (towers, turntables, reverberation paddles, MAPS, etc.) can be connected to the two Device Interface ports located on the rear panel of the Model 2090 controller. For easy set up of an EMC facility, it is recommended that the turntable be connected to the Device 2 interface port. The controllers default settings are for a tower connected to the Device 1 interface port and a turntable connected to the Device 2 port.
Primary device connection is accomplished by way of a dual fiber cable included with the device. This cable terminates into two ST connectors that are identical at both ends. The cable is symmetrical; either end can be connected to the controller. A fiber optic cable that is connect to the IN port of a device should, at the other end, be connected to the primary OUT port of the motorbase. A fiber connected to the OUT port of the device should, at the other end, be connected to the primary IN port of the motorbase. Older motor base designs have only one fiber optic connector pair, while the newest motor base interface provides a secondary interface reserved for future expansion.
NOTE: Fiber optic cabling for each device should not be allowed to 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 Position Controller (or hand controller), rotate the motor base shaft to verify proper operation. Run the motorbase down to the lower limit CCW and then back it off from the lower limit just a bit. This step will help after the turntable is attached to the motorbase and it is time to set the rotation limits for the turntable. Disconnect the power for the Model 2090 and the motor base before proceeding with the assembly of the turntable. Disconnect the fiber optic cables from the units so they will not be damaged during installation.

ASSEMBLY INSTRUCTIONS
CAUTION Ensure power is OFF and secured before proceeding
further.
1) Position the turntable mechanical assembly on the floor. The
turntable mechanical assembly has a 44 inch (112 cm) wide base plate that needs to rest on a flat surface. To insure proper alignment of the drive shaft, the bottom surface of all three sub assemblies: the TT mechanical assembly, the drive shaft assembly and the motor drive will need to be installed at the same level with each other. It may be necessary to place shims under the base if the floor is not flat. The table base plate has four holes for fastening the unit to the floor using 5/16" diameter screws but will stay in place due to its own weight.
2) After the turntable is in position, remove the plastic gear box
cover plate by loosening the 4 plastic bolts used to hold it in place.
If the optional shaft kit was purchased please continue to the Optional Shaft Kit Installation Instructions and disregard the remainder of the instructions in this section.
3) Install the aluminum shaft adapter to the black shaft out of the
turntable gearbox. A ¼” phenolic (brown plastic) pin is used to key it to the black shaft. A spacer piece fits inside the shaft adapter, between the adapter and the pin to help secure the pin in place. Two setscrews (size 8-32) lock the adapter in place on the shaft.
4) The gray hose coupling with two hose clamps around it is now
slipped on to the shaft adapter.
5) The motor drive is held to the turntable base by an aluminum
bracket. The bracket attaches to the ¾” base plate of the turntable using two ½-13 x ¾” bolts. There are two standoffs that attach the bracket to the motor base at the correct distance.

6) Position the motor drive so that its shaft slips into the hose
coupling. The bracket installed in step 5 should now be in place. Secure the bracket to the motorbase using the ¼ x 1-1/4” hex head cap screws provided. Both hose clamps should be tightened to secure the gray hose coupling around the shafts.
7) The gearbox cover can now be placed on the gearbox and the 4
bolts that hold it in place inserted and tightened.
