7.6 Viewing and modifying variables The most powerful feature of the RS-232 inte rf ace is the ability of a host computer to view and modify the Analyzer's internal vari ab les.

There are two acceptable methods of generating accurate CO concentrations for calibrating the Model 300. One method uses a single cylinder of CO-in-ai r and a m eans of accurately diluting the cylinder gas with zero air. Th is is illustrated in Figure 8.1. Alternatively, several c ylinders of CO-in-air, of appropriate concentrations, may be used wi[...]

12. Set the calibrator to prod uce 75% to 85% of the UR L (upper range limit). This will be 40 ppm ±2.5 ppm on the 50 ppm range. 13. Allow the Analyzer to sample the CO concentration. 14. Push “CAL” 15. Enter password. (If enabled) 16. Push “CONC” 17. Change the span value in the display to the calc ulated CO concentration in the manifold [...]

10.2 Troubleshooting fundamental analyzer operation When the Analyzer is turned on, several ac tion s will normally occur which indicate the proper functioning of basic instrument sub-system s. These actions are: 1. The sample pump should start. 2. The green sample light on the front panel should turn on. 3. The Display should energize and disp lay[...]

absence of these actions will usually indicat e either a CPU or Display failure. To determine which module is defective, perform the following procedure: 1. Turn off power. 2.

Check for leaks in the pneumatic system as described in Section 11.2.[...]

3. Check for dirty pneumatic system components and clean or replace as necessary as described in Section 11.3. 4.

Check and adjust as required. 10.6 T[...]

Low Flow: 1. Check for leaks as described in Section 11.2. Repair and re-check. 2. Check for dirty sample filte r or dirty orifice filter(s). 3. Check for partially plugged pneum atic lines, orif ices, or valves. High Flow: 1. The most common cause of high flow is a leak around an orifice. To correct, remove the orifice as de scribed in Section 11.[...]

If thermistor resistance(s) ar e within the proper range, check the temperature linearzation circuits on the DC Power Supply Board as described in Section 10.6.4. If temperature sensor readings appear accura te but contro l temperatures are not being maintained at their prop er value, check the operation of the h eaters as follows: 1. Observe the i[...]

Analog to Digital (A/D) conversion is accomplished by performing a Voltage to Frequency (V/F) conversion on the input signa l at IC U17 and running the frequency output to a counter compri sed of IC's U20, U21, U22.

micro-processor is also used to adjust for offset and gain needed to match DAC outputs to external voltage standards, and no on board adjustments are needed or provided for this function. The outputs of all DAC's are "looped-back" to Analog input (via the Mother Board) channels. This loop back allows for au tomatic micro-processor ch[...]

10.6.7 Checking the Opto Interrupter Correct operation of the Opto Interrupte r on the gas filte r wheel can be confirmed by connecting an oscilloscope U6, Pin 11 on th e Sync Demodulator board and comparing the waveform to Figure 10.1. The waveform s hould be symmetrical and 5 Volts peak to peak. FIGURE 10.1 OPTO PICKUP WAVEFORM FIGURE 10.2 DETECT[...]

5. Confirm the wave from of the optic al signal by attachi ng an oscilloscope to the Sync Demodulator board a U2 Pin 7. The oscilloscope trace should appear like those shown in Figure 10.2. In particular the wave form should be symmetrical and should have distinct flat regi ons at the top and bottom of the pulses. 6. If unable to achieve 4200 mV on[...]

APPENDIX B: TIPS ON CONNECTING THE TELEDYNE API ANALYZER RS-232 INTERFACE Teledyne API analyzers use the RS-232 communicat ions protocol to al low the instrum ent to be connected to a variety of computer based equipment. RS-232 has been used for many years and as equipment has becom e more advanced, connections between various types of hardware hav[...]

4. Null modems - here the connector changes th e internal wiring so that DTE devices can become DCE or vice versa. The main internal ch ange is swap ping pin 2 and 3 so that data is transmitted and received on opposite pins. NOTE Null modems can also combin e gender changer or adapter features in the design. When making up an adapter cable be caref[...]

The modem is configured as Data Communi cations Equipment (DCE), and may have additional signal requirements to enable transm ission. See modem troubleshooting section below. NOTE Modems are especially difficult because they may have pins that need to be at certain EI A RS-232 levels before the modem will transmit data. The most common requir ement[...]
