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.
