Teledyne API – Technical Manual - Model 300E Family CO Analyzers

Theory of Operation

11.5.10.3.Display

The main display of the analyzer is a vacuum florescent display with two lines of 40 text characters each. Information is organized in the following manner (see Figure 11-17):

∙Mode Field: Displays the name of the analyzer’s current operating mode.

∙Message Field: Displays a variety of informational messages such as warning messages, operation data and response messages during interactive tasks.

∙Concentration Field: Displays the actual concentration of the sample gas currently being measured by the analyzer.

∙Keypad Definition Field: Displays the definitions for the row of keys just below the display. These definitions are dynamic, context sensitive and software driven.

Figure 11-18: Keyboard and Display Interface Block Diagram

The keyboard/display interface electronics of the M300E/EM Analyzer watches the status of the eight front panel keys, alerts the CPU when keys are depressed, translates data from parallel to serial and back and manages communications between the keyboard, the CPU and the front panel display. Except for the Keyboard interrupt status bit, all communication between the CPU and the keyboard/display is handled by way of the instrument’s I2C bus. The CPU controls the clock signal and determines when the various devices on the bus are allowed to talk or required to listen. Data packets are labeled with addresses that identify for which device the information is intended.

An anti-ESDwrist strap keeps the person wearing it at or near the same potential as other grounded objects in the work area and allows static charges to dissipate before they can build to dangerous levels. Anti-ESDwrist straps terminated with alligator clips are available for use in work areas where there is no available grounded plug 14.4.2.2.Working at an Anti-ESDWork Bench 14.4.2.1.Working at the Instrument Rack 4.Place the item in the container ESD Hazard CAUTION – Avoid Warranty Invalidation∙DO NOT use pink-polybags This page intentionally left blank A Primer on Electro-StaticDischargePage Page Page Page Page Page Warnings, This page intentionally left blank Technical Manual - Model 300E Family CO Analyzers APPENDIX A-1:SOFTWARE MENU TREES, REVISION L.8 SAMPLE TEST1MSG1 <TST TST> SAMPLE SETUPRNGE PASS CLK MORE Figure A-3:Primary Setup Menu  DAS Submenu APPENDIX A-1:Software Menu Trees, Revision L.8ACAL1 APPENDIX A-1:Software Menu Trees, Revision L.8 SAMPLESETUP CO, 310, REPORTED CO2, 311, REPORTEDO2, 312 REPORTED APPENDIX A-1:Software Menu Trees, Revision L.8 Figure A-6:DIAG Menu A-7 Value Range Setup VariableDefault Value Numeric Units Units DefaultNumeric Value Numeric Setup VariableDefault APPENDIX A-2:Setup Variables For Serial I/O Value Setup VariableDefault Numeric Numeric Setup VariableDefault APPENDIX A-2:Setup Variables For Serial I/O Value Setup VariableDefault Numeric Numeric Setup VariableDefault Same settings as Value Setup VariableDefault Numeric Numeric Setup VariableDefault APPENDIX A-2:Setup Variables For Serial I/O Value Setup VariableDefault Numeric Numeric Setup VariableDefault APPENDIX A-2:Setup Variables For Serial I/O Value Setup VariableDefault Numeric Numeric Setup VariableDefault APPENDIX A-2 Setup Variables For Serial I/O APPENDIX A-3:Warnings and Test Functions NameMessage Text Description A-22 NameMessage Text Description DESCRIPTION A-23TEST FUNCTION NAME MESSAGE TEXT A-24 APPENDIX A-3 Warnings and Test FunctionsSTABIL_SAMPLES DESCRIPTION A-25TEST FUNCTION NAME MESSAGE TEXT APPENDIX A-4:Signal I/O Definitions Signal NameBit or Channel Number APPENDIX A-4:Signal I/O Definitions A-27 Signal NameBit or Channel Number Description Description Bit or ChannelNumber Signal Name A-29 Signal NameBit or Channel Number Description Description Signal NameAPPENDIX A-4:Signal I/O Definitions Bit or Channel Number A-31 NameDescription APPENDIX A-5:DAS Triggers and Parameters A-32 NameDescription Units A-33 NameDescription Units COMMAND APPENDIX A-6:Terminal Command DesignatorsTable A-7:Terminal Command Designators APPENDIX A-6:Terminal Command Designators MODBUS Floating Point Input Registers MODBUSRegister Address dec., 0-based Units MODBUS Floating Point Holding RegistersMODBUS Description Description MODBUS Discrete Input Registerssingle-bit; read-only MODBUS Description MODBUS Coil Registerssingle-bit;read/write MODBUS 04288D DCN5752 APPENDIX B - Spare Parts This page intentionally left blank M300E Spare Parts List Part NumberDescription Description M300E Spare Parts ListReference: 05362J DCN5494 Part Number M300EM Spare Parts List Part NumberDescription Description M300EM Spare Parts ListReference: 05424H DCN5494 Part Number 21-30 M300EM Recommended Spare Parts Stocking Levels6-10 11-20 Reference: 0096004C M300E/EX Expendables Kit ASSY, SOURCE 000941000ORIFICE, 13 MIL SAMPLE FLOW 009550500 009560301 Please complete the following table APPENDIX C Warranty/Repair QuestionnaireT300/T300M and M300E/EM Email: api-customerservice@teledyne.com 2v/DIV APPENDIX C Warranty/Repair QuestionnaireEmail: api-customerservice@teledyne.com T300/T300M and M300E/EM 04288D DCN5752 APPENDIX D – Wire List and Electronic Schematics 04288D DCN5752 This page intentionally left blank Interconnect List, M300E/EU, SNs 100 and greater FROM FROM This page intentionally left blank Page Sync Demod Page 3 03297k_3.sch D C B ASync Demod Page 1 03297k_1.sch Sync Demod Page 2 03297k_2.sch proper authorization 1.
