Maintenance Schedule & Procedures

12.MAINTENANCE SCHEDULE & PROCEDURES

Predictive diagnostic functions, including data acquisition records, failure warnings and test functions built into the analyzer, allow the user to determine when repairs are necessary without performing painstaking preventative maintenance procedures. There are, however, a minimal number of simple procedures that when performed regularly will ensure that the analyzer continues to operate accurately and reliably over its lifetime. Repairs and troubleshooting are covered in Section Error! Reference source not found. of this manual.

12.1.MAINTENANCE SCHEDULE

Table 12-1shows a typical maintenance schedule for the analyzer. Please note that in certain environments (i.e. dusty, very high ambient pollutant levels) some maintenance procedures may need to be performed more often than shown.

NOTE

A Span and Zero Calibration Check (see CAL CHECK REQ’D Column of Table 12-1)must be performed

following certain of the maintenance procedure listed below. See Sections 9.3 and 9.4 for instructions on performing checks.

CAUTION

GENERAL SAFETY HAZARD

Risk of electrical shock. Disconnect power before performing any of the following

operations that require entry into the interior of the analyzer.

CAUTION

QUALIFIED PERSONNEL

The operations outlined in this section are to be performed by qualified maintenance

personnel only.

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 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 AnalyzersAPPENDIX A-1:SOFTWARE MENU TREES, REVISION L.8 SAMPLE TEST1MSG1 RNGE PASS SAMPLE SETUPCLK MORE <TST TST>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-7Default Value Setup VariableNumeric Units Value RangeNumeric DefaultValue UnitsDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericDefault Setup VariableNumeric ValueDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericDefault Setup VariableNumeric ValueDefault Setup VariableSame settings as NumericDefault Setup VariableNumeric ValueDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericDefault Setup VariableNumeric ValueDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericDefault Setup VariableNumeric ValueDefault Setup VariableAPPENDIX A-2:Setup Variables For Serial I/O NumericMessage Text NameDescription APPENDIX A-3:Warnings and Test FunctionsMessage Text NameDescription A-22TEST FUNCTION NAME A-23MESSAGE TEXT DESCRIPTIONA-24 APPENDIX A-3:Warnings and Test FunctionsSTABIL_SAMPLES TEST FUNCTION NAME A-25MESSAGE TEXT DESCRIPTIONBit or Channel Number Signal NameAPPENDIX A-4:Signal I/O Definitions APPENDIX A-4:Signal I/O DefinitionsBit or Channel Number Signal NameDescription A-27Number Bit or ChannelSignal Name DescriptionRear board temperature MUX analog inputs Signal NameBit or Channel Number DescriptionAPPENDIX A-4:Signal I/O Definitions Signal NameBit or Channel Number DescriptionDescription NameAPPENDIX A-5:DAS Triggers and Parameters A-31Description NameUnits A-32Description NameUnits A-33Table A-7:Terminal Command Designators APPENDIX A-6:Terminal Command DesignatorsAPPENDIX A-6:Terminal Command Designators COMMANDRegister Address MODBUSdec., 0-based MODBUS Floating Point Input RegistersMODBUS MODBUS Floating Point Holding RegistersDescription Unitssingle-bit; read-only MODBUS Discrete Input RegistersMODBUS Descriptionsingle-bit;read/write MODBUS Coil RegistersMODBUS Description04288D DCN5752 APPENDIX B - Spare PartsThis page intentionally left blank M300E Spare Parts List Part NumberDescription Reference: 05362J DCN5494 M300E Spare Parts ListPart Number DescriptionM300EM Spare Parts List Part NumberDescription Reference: 05424H DCN5494 M300EM Spare Parts ListPart Number Description6-10 M300EM Recommended Spare Parts Stocking Levels11-20 21-30Reference: 0096004C M300E/EX Expendables KitORIFICE, 13 MIL SAMPLE FLOW 000941000009550500 ASSY, SOURCE009560301 T300/T300M and M300E/EM APPENDIX C Warranty/Repair QuestionnaireEmail: api-customerservice@teledyne.com Please complete the following tableEmail: api-customerservice@teledyne.com APPENDIX C Warranty/Repair QuestionnaireT300/T300M and M300E/EM 2v/DIV04288D 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 1 03297k_1.sch D C B ASync Demod Page 2 03297k_2.sch Sync Demod Page 3 03297k_3.schSchematics for PCA 03296, Sync Demod 1.
