Legacy 2000 Chapter 1 Introduction elcome to the Legacy 2000, the new genera- tion of chemical control systems. The Legacy 2000 controls up to two different products, automatically, manually, or under external control. New technology allows the Legacy 2000 console to communicate with remotely mounted control modules through a single cable.
Legacy 2000 Following is a listing of the chapters in this manual, along with a brief description of the information found in each chapter. Chapter 1 - “Introduction” - A brief overview of the User Guide. Chapter 2 - “Start-up” - Describes the system start-up sequence followed when powered on.
Legacy 2000 Chapter 2 Start-up TART EQUENCE he Legacy system monitors the accessory position of the ignition switch. When the ignition switch is turned on the Legacy system begins its start-up sequence. The console will alternate between the two screens shown in Fig. 2-1 while it is performing its system check.

Legacy 2000 ONTROL ALVE AILURE (Liquid Applicator) he Legacy system can be operated at a reduced level of accuracy in the event of a flow control valve failure. To operate the sprayer, it is necessary to manually adjust the flow control valve to provide sufficient pressure to the booms to provide a good spray pattern.
Legacy 2000 changes in boom widths. If booms sections are turned on or off, the pressure must be read- justed manually. MIDWEST TECHNOLOGIES RECOM- MENDS THIS PROCEDURE ONLY AS A TEMPORARY, EMERGENCY PROCE- DURE. THE PROBLEM WITH THE FLOW CONTROL VALVE SHOULD BE RE-...
Legacy 2000 MIDWEST TECHNOLOGIES RECOMMENDS THIS PROCEDURE ONLY AS AN EMER- GENCY, TEMPORARY PROCEDURE. THE PROBLEM WITH THE FLOW METER OR PRESSURE SENSOR SHOULD BE RE- SOLVED AS SOON AS PRACTICAL SO THAT FULL CONTROL OF THE SPRAYER CAN AGAIN BE ENJOYED.

Legacy 2000 LOSSARY The definitions in this glossary are worded to fit the needs of this manual only and may not apply to all operations in general. AutoRange® Valve - A three port valve which controls both the main liquid flow and bypass flow. Boom - An application width that is assigned a value and is used to calculate area.
Page 67
Legacy 2000 Console - An operator interface which allows the operator to set and monitor all application condi- tions, such as speed, swath width, and current product flow rate, etc., and sends the necessary information on the bus cable so the system can maintain the application rate at that designated by the operator.
