Theory of Operation

11.5.7.I2C DATA BUS

An I2C data bus is used to communicate data and commands between the CPU and the keyboard/display interface and the relay board. I2C is a two-wire, clocked, digital serial I/O bus that is used widely in commercial and consumer electronic systems. A transceiver on the motherboard converts data and control signals from the PC-104 bus to I2C. The data is then fed to the keyboard/display interface and finally onto the relay board.

Interface circuits on the keyboard/display interface and relay boards convert the I2C data to parallel inputs and outputs. An additional, interrupt line from the keyboard to the motherboard allows the CPU to recognize and service key presses on the keyboard.

POWER UP CIRCUIT

This circuit monitors the +5V power supply during start-up and sets the analog outputs, external digital I/O ports, and I2C circuitry to specific values until the CPU boots and the instrument software can establish control.

11.5.8.POWER SUPPLY/ CIRCUIT BREAKER

The analyzer operates on 100 VAC, 115 VAC or 230 VAC power at either 50Hz or 60Hz. Individual units are set up at the factory to accept any combination of these five attributes. As illustrated in Figure 11-13,power enters the analyzer through a standard IEC 320 power receptacle located on the rear panel of the instrument. From there it is routed through the ON/OFF Switch located in the lower right corner of the Front Panel. A 6.75 Amp circuit breaker is built into the ON/OFF Switch.

AC power is distributed directly to the sample gas pump. The bench and GFC Wheel heaters as well as the GFC Wheel receive AC power via the relay board.

AC Line power is converted stepped down and converted to DC power by two DC power supplies. One supplies +12 VDC, for valves and the IR source, while a second supply provides +5 VDC and ±15 VDC for logic and analog circuitry. All DC voltages are distributed via the relay board.

CAUTION

GENERAL SAFETY HAZARD

Should the AC power circuit breaker trip, investigate and correct the condition causing

this situation before turning the analyzer back on.

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 Rack4.Place the item in the container ∙DO NOT use pink-polybags ESD HazardCAUTION – Avoid Warranty Invalidation 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 AnalyzersAPPENDIX A-1:SOFTWARE MENU TREES, REVISION L.8 MSG1 SAMPLETEST1 <TST TST> SAMPLE SETUPRNGE PASS CLK MOREACAL1 Figure A-3:Primary Setup Menu  DAS SubmenuAPPENDIX A-1:Software Menu Trees, Revision L.8 APPENDIX A-1:Software Menu Trees, Revision L.8 O2, 312 REPORTED SAMPLESETUPCO, 310, REPORTED CO2, 311, REPORTED APPENDIX A-1:Software Menu Trees, Revision L.8 Figure A-6:DIAG Menu A-7Value Range Setup VariableDefault Value Numeric UnitsUnits DefaultNumeric ValueNumeric Setup VariableDefault APPENDIX A-2:Setup Variables For Serial I/OValue Setup VariableDefault NumericNumeric Setup VariableDefault APPENDIX A-2:Setup Variables For Serial I/OValue Setup VariableDefault NumericNumeric Setup VariableDefault Same settings asValue Setup VariableDefault NumericNumeric Setup VariableDefault APPENDIX A-2:Setup Variables For Serial I/OValue Setup VariableDefault NumericNumeric Setup VariableDefault APPENDIX A-2:Setup Variables For Serial I/OValue Setup VariableDefault NumericNumeric Setup VariableDefault APPENDIX A-2:Setup Variables For Serial I/OAPPENDIX A-3:Warnings and Test Functions NameMessage Text DescriptionA-22 NameMessage Text DescriptionDESCRIPTION A-23TEST FUNCTION NAME MESSAGE TEXTSTABIL_SAMPLES A-24APPENDIX A-3:Warnings and Test Functions DESCRIPTION A-25TEST FUNCTION NAME MESSAGE TEXTAPPENDIX A-4:Signal I/O Definitions Signal NameBit or Channel Number APPENDIX A-4:Signal I/O DefinitionsA-27 Signal NameBit or Channel Number DescriptionDescription Bit or ChannelNumber Signal NameDescription Signal NameRear board temperature MUX analog inputs Bit or Channel NumberDescription Signal NameAPPENDIX A-4:Signal I/O Definitions Bit or Channel NumberA-31 NameDescription APPENDIX A-5:DAS Triggers and ParametersA-32 NameDescription UnitsA-33 NameDescription UnitsCOMMAND APPENDIX A-6:Terminal Command DesignatorsTable A-7:Terminal Command Designators APPENDIX A-6:Terminal Command DesignatorsMODBUS Floating Point Input Registers MODBUSRegister Address dec., 0-basedUnits MODBUS Floating Point Holding RegistersMODBUS DescriptionDescription MODBUS Discrete Input Registerssingle-bit; read-only MODBUSDescription MODBUS Coil Registerssingle-bit;read/write MODBUS04288D DCN5752 APPENDIX B - Spare PartsThis page intentionally left blank Description M300E Spare Parts ListPart Number Description M300E Spare Parts ListReference: 05362J DCN5494 Part NumberDescription M300EM Spare Parts ListPart Number Description M300EM Spare Parts ListReference: 05424H DCN5494 Part Number21-30 M300EM Recommended Spare Parts Stocking Levels6-10 11-20Reference: 0096004C M300E/EX Expendables KitASSY, SOURCE 000941000ORIFICE, 13 MIL SAMPLE FLOW 009550500009560301 Please complete the following table APPENDIX C Warranty/Repair QuestionnaireT300/T300M and M300E/EM Email: api-customerservice@teledyne.com2v/DIV APPENDIX C Warranty/Repair QuestionnaireEmail: api-customerservice@teledyne.com T300/T300M and M300E/EM04288D DCN5752 APPENDIX D – Wire List and Electronic Schematics04288D DCN5752 This page intentionally left blankInterconnect 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.schproper authorization 1.
