2.3.4 STARTUP, FUNCTIONAL CHECKS, AND INITIAL CALIBRATION IMPORTANT Impact on Readings or Data The analyzer’s cover must be installed to ensure that the temperatures of the GFC Wheel and absorption cell assemblies are properly controlled. We recommend reading Section 6 to become familiar with the principles of operation. When the instrument is first started (Section 2.3.4.1, check its functionality (Section 2.3.4.3) and run an initial calibration (Section 4).
Page 57: Alerts: Warnings And Other Messages
Figure 2-29. Home Page Example 2.3.4.2 ALERTS: WARNINGS AND OTHER MESSAGES Because internal temperatures and other conditions may be outside the specified limits during the analyzer’s warm-up period, the software will suppress most Alerts for 30 minutes after power up. The Alerts page (Figure 2-30) shows the status of any active warning conditions or user-configured Events.
Page 58: Functional Checks
2.3.4.3 FUNCTIONAL CHECKS After warm-up, verify that the software properly supports any hardware options that are installed (Setup>Instrument menu), and that the instrument is functioning within allowable operating parameters. Check the Dashboard page against the instrument’s Final Test and Validation Data sheet, which lists these values as they appeared before the instrument left the factory.

Page 79: Manual Calibration Of Voltage Range Analog Outputs
2.5.8.1 MANUAL CALIBRATION OF VOLTAGE RANGE ANALOG OUTPUTS It is possible to manually calibrate the voltages by using a voltmeter connected across the output terminals (Figure 2-54) and changing the output signal level in the Manual Adjust field of the Analog Outputs Calibration screen (Figure 2-53). Refer to Table 2-15 for voltage tolerances.
Page 80: Manual Adjustment Of Current Range Analog Outputs
2.5.8.2 MANUAL ADJUSTMENT OF CURRENT RANGE ANALOG OUTPUTS These instructions assume that the Current Loop Option is installed (Section 2.3.1.3). This option places circuitry in series with the output of the D-to-A converter on the motherboard that changes the normal DC voltage output to a 0-20 milliamp signal. Adjusting the signal zero and span levels of the current loop output is done by raising or lowering the voltage output of the D-to-A converter circuitry on the analyzer’s motherboard.

2.6 TRANSFERRING CONFIGURATION TO OTHER INSTRUMENTS Once an instrument is configured, the same configuration can be copied to other instruments of the same Model. This encompasses essentially anything the user can conFigure and does not apply to instrument-specific settings such as those that are configured at the factory for calibration.

3 COMMUNICATIONS AND REMOTE OPERATION This instrument’s rear panel connections can include an Ethernet port, a USB port (option) and two serial communications ports labeled RS232, which is the COM1 port in the software menu, and COM2 (refer to Figure 2-2). These ports allow the ability to communicate with, issue commands to, and receive data from the analyzer through an external computer system or terminal.

MAINTENANCE AND SERVICE 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.

Page 112: Maintenance Procedures
5.6 MAINTENANCE PROCEDURES The following procedures are to be performed periodically as part of the standard maintenance of the T300. 5.6.1 REPLACING THE SAMPLE PARTICULATE FILTER The particulate filter should be inspected often for signs of plugging or contamination. We recommend that the filter and the wetted surfaces of the filter housing are handled as little as possible when you change the filter.
Page 113: Rebuilding The Sample Pump
If you can’t locate the leak by the above procedure, use the following procedure. Obtain a leak checker similar to the Teledyne API P/N 01960, which contains a small pump, shut-off valve and pressure gauge. Alternatively, a convenient source of low-pressure gas is a tank of span gas, with the two-stage regulator adjusted to less than 15 psi with a shutoff valve and pressure gauge.
Page 114: Performing A Sample Flow Check
High flows indicate leaks downstream of the Flow Control Assembly. 5.6.5 CLEANING THE OPTICAL BENCH The T300/T300M sensor assembly and optical bench are complex and delicate. Disassembly and cleaning is not recommended. Please check with the factory before disassembling the optical bench.
Page 115: Cleaning Exterior Surfaces Of The T300/T300M
See the wiring interconnect diagram and interconnect list in Appendix B. 5.7.1 CLEANING EXTERIOR SURFACES OF THE T300/T300M If necessary, the exterior surfaces of the T300/T300M can be cleaned with a clean damp cloth. Do NOT submerge any part of the instrument and do NOT use any cleaning solution.
Page 116: Fault Diagnosis With Alerts
5.7.2 FAULT DIAGNOSIS WITH ALERTS The most common and/or serious instrument failures will result in a warning message, called an Alert. Table 5-4 lists some of the more common Alert messages, along with their meaning and recommended corrective action. It should be noted that if more than two or three warning Alerts occur at the same time, it is often an indication that some fundamental analyzer sub-system (power supply, relay board, motherboard) has failed, rather than being an indication of the specific failures referenced by the warning Alerts.
Page 117: Fault Diagnosis With Dashboard Functions
The acceptable ranges for these test functions are listed in the “Nominal Range” column of the analyzer Final Test and Validation Data Sheet (T300, P/N 04307 and T300M, P/N 04311) shipped with the instrument. Values outside these acceptable ranges indicate a failure of one or more of the analyzer’s subsystems.

Section 5.6.4. If this test shows the flow to be correct, check the pressure sensors as described in Section 5.7.14.11. The T300/T300M has one main gas flow path. With the IZS or zero/span valve option installed, there are several subsidiary paths but none of those are displayed on the front panel or stored by the DAS.
Page 124: Flow Is Zero
5.7.9.1 FLOW IS ZERO The unit displays a SAMPLE FLOW warning message on the front panel display or the SAMPLE FLOW test function reports a zero or very low flow rate. Confirm that the sample pump is operating (turning). If not, use an AC voltmeter to make sure that power is being supplied to the pump if no power is present at the electrical leads of the pump.
Page 125: Displayed Flow = "Warnings
5.7.9.4 DISPLAYED FLOW = “WARNINGS” This warning means that there is inadequate gas flow. There are four conditions that might cause this: 1. A leak upstream or downstream of the flow sensor 2. A flow obstruction upstream or downstream of the flow sensor 3.

Individual control loops are used to maintain the set point of the absorption bench, filter wheel and IR photo-detector temperatures.

A voltmeter should be used to verify that the DC voltages are correct per the values in the table below, and an oscilloscope, in AC mode, with band limiting turned on, can be used to evaluate if the supplies are producing excessive noise (> 100 mV p-p). Table 5-10.

Page 148: The Measure Reference Ratio
6.1.2.2 THE MEASURE REFERENCE RATIO The T300/T300M determines the amount of CO in the sample chamber by computing the ratio between the peak of the measurement pulse (CO MEAS) and the peak of the reference pulse (CO REF).
Page 149: Interference And Signal To Noise Rejection
Sample Chamber, but to a lesser extent Figure 6-4. Effect of CO in the Sample on CO MEAS & CO REF Once the T300/T300M has computed this ratio, a look-up table is used, with interpolation, to linearize the response of the instrument. This linearized concentration value is combined with calibration SLOPE and OFFSET values to produce the CO concentration which is then normalized for changes in sample pressure.

6.4.2.3 GFC WHEEL A synchronous AC motor turns the GFC Wheel motor. For analyzers operating on 60Hz line power this motor turns at 1800 rpm. For those operating on 50Hz line power the spin rate is 1500 rpm. The actual spin rate is unimportant within a large range since a phase lock loop circuit is used to generate timing pulses for signal processing.

AMPLE RESSURE These are analog signals from two sensors that measure the pressure and flow rate of the gas stream at the outlet of the sample chamber. This information is used in two ways.
