INTRODUCTION

The ETS-Lindgren Model 2087 is an electric powered turntable
platform system designed to be used with the Model 2090
Positioning Controller for EMI compliance testing. The Model
2087 is available in 2.03 and 3.03 meter sizes, both designed for
indoor or outdoor use.

The sectional turntable top surface is made of aluminum. The
conductive metal top is fitted with a ground brush to electrically
couple the turntable to the ground plane. The brush provides
continuous contact with the floor flange supplied. 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.

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. This hole also provides access to the limit
switch adjustment knobs and the primary circuit breaker.

To prevent over-travel of the turntable in either direction of
movement, mechanical limits can be adjusted. The limit switch
adjustments are on the encoder/limit assembly which is located
below the turntable top. For continuous rotation without limits,
adjustments can be made in the encoder/limit assembly. Soft limits
can be set within the mechanical limits, using the Model 2090
positioning controller. Signal I/O between the turntable and
positioning controller is provided by fiber-optic control lines. Standard Configuration
