Operation and Maintenance Manual, Ultrasonic Fish Deterrent System

Abstract

The ultrasonic fish deterrent system, developed at Waterways Experiment Station, Vicksburg, MS, consists of eight underwater transducers powered by eight 2 KVA switching amplifiers. The input signals to these amplifiers are controlled by a microprocessor and signal conditioner, also developed at WES. The timing durations and frequencies are variable, set by an external computer and can be changed to fit the parameters deemed optimum for the conditions found. This report describes the various circuits, wiring diagrams, and function charts of the control chassis and microprocessor located in the console as well as instructions for changing the parameters with a computer.
