SYSTEM DESCRIPTION The EMCO Equipment Testing Turntable is designed for use in compliance testing. Rotation is provided by a drive system which includes an electric motor, electric brake and a drive gear reduction arrangement. Approximately 370 degrees of rotation are provided before travel is stopped by mechanically actuated limit switches, which are preset at the factory. The base of the turntable is constructed of marine grade plywood, the platform is fabricated of either marine grade plywood covered with formica or solid 3/8" steel plate, depending on the model chosen. Both platforms are designed to provide strength and rigidity and resist degradation due to harsh environments. The drive unit is attached to the base section, as is the phenolic support and the stationary member of the center bearing. In addition to mechanical limits, the controller has the capability to move the table a full 370 degrees of rotation as well as any smaller arc of the circle. For further explanation of controller functions and programming, see the manual section entitled "Controller Operation and Programming".
