1.0 INTRODUCTION
Vertex 7133B ACU Antenna Controller
1.1 The Purpose of the 7122B/7133B Manual
The purpose of this manual is to provide the user with the information necessary to
install and operate the Vertex Model 7122B/7133B Antenna Control Unit (ACU). This
manual contains only the information related to the 7122B/7133B ACU and contains
only limited information about the antenna structure or other equipment peripheral to
the 7122B/7133B.
1.2 General Information about the 7122B/7133B ACU
The 7122B/7133B controller series is designed for applications requiring high
reliability and low cost. The readout system provides 0.02E resolution, using
brushless 2.5 KHz resolvers. The motor drive circuit provides the operator with single
speed, real-time drive control.
The 7133B controls the elevation and azimuth movement of the antenna and the
polarization movement of the feed horn. The 7122B controls only the elevation and
azimuth movement of the antenna. Otherwise, the 7122B and the 7133B are
identical.
1.2.1 System Hardware
The 7122B/7133B controller consists of the following subsystems:
Model 7122B/7133B ACU
Model 7122B/7133B OU
Resolver
7122 and 7133 are Vertex’s basic system model numbers. ACU is the acronym for
antenna control unit, which refers to the 19-inch rack-mountable unit used in the
shelter or other antenna control room. OU is the acronym for outside unit, which
refers to the weather-proof cabinet typically installed near the antenna.
The ACU interfaces with starters and motors for elevation, azimuth, and polarization
positioning of the antenna. The elevation, azimuth, and polarization limit interfaces
are normally closed switches that open upon engagement.
