INTRODUCTION
The ETS-Lindgren Model 2080/2081 Turntable Series is a family
of electric powered turntable platform systems designed to be used
with the Model 2090 Positioning Controller for EMI compliance
testing. The primary difference between the Model 2080 and 2081
is the turntable top surface. The Model 2080 series turntables are
equipped with a rugged textured ABS surface laminated to a PVC
plate. Both materials are non-conductive and waterproof. The
Model 2081 series turntables have a conductive table top with a
continuous ground brush to electrically couple the turntable to the
ground plane.
The turntable tops are a one piece design that will support EUT’s
weighing up to 450kg (1000 lb) distributed load. The outside
support for the turntable includes casters which aid in the support
of a cantilevered load on the outside of the turntable. They are
powered by a single phase electric motor, driving a chain and
sprocket assembly. The 1.2 and 1.5 meter diameter table tops may
be removed to provide easy access in the event that service is
required.
The turntable electronics are located in the shielded motor base
enclosure with a fiber optic I/O (input/output) cable that interfaces
with the Model 2090 controller. The low profile drive motor and
gearing are located beneath the tabletop.
To prevent over-travel of the turntable in either direction of
movement, mechanical limits should be set using the conveniently
located knobs on the motor base enclosure. Soft rotational limits
can be set within the mechanical limits, using the Model 2090
Positioning Controller.
The 2081 ground brushes are attached directly to the top of the
table and are in continuous contact with the floor-flange supplied.
Conductive grease enhances contact between the ground brush and
floor flange.
