  • Page 27: Chapter 3. Operation

    The interconnecting wiring between the transmitter and display must be completed before powering To power up the benchtop TMO2D, press the red power key to the right of the display. Other TMO2D models have no power switch, and begin operating when the external power to which they have been connected has been turned on.

  • Page 28: The Keypad

    Figure 12: The TMO2D Display RS-232C Serial Port The TMO2D contains a bidirectional, industry-standard RS-232C serial port which can be connected to a terminal or computer that supports the RS-232C protocol (see The Outputs Menu on page 30.) All keypad and most display operations can be performed remotely through this serial port.

  • Page 29: Chapter 4. Basic Programming

    This user program has six main menus. Use the front panel keypad and display to check or change the settings for current operating parameters. The TMO2D stores data in memory and will retain it for several years if the main power is lost.

  • Page 30: Key Functions

    The [] key enables you to scroll forward through the menu options; it is equivalent to pressing the [NO] key in the Menu Mode. Programming the TMO2D Using the Display This section briefly explains display and menu navigation, and then takes you step-by-step through the programming procedure.

  • Page 31: Menu Navigation

    These submenus allow you to alter operating parameters. Once entered, these values remain in the display memory until you change them. (Appendix B offers a flow diagram of the Setup Menu in Figure 26 on page 82.) TMO2D User’s Manual...

  • Page 32: Set Time

  • Page 33: Set Backlight

    If you have selected one of the five preprogrammed gases, the program returns to the Set Gas/Units/Scaling? submenu. However, if you have selected OTHER , the TMO2D asks for a gas label. A specific label can contain up to 8 characters.

  • Page 34: Set Contrast

    4.4.6 Set Display? Although this feature is not commonly used, the TMO2D, when used with the TMO2, can display compensation values for pressure or the percentage of background gas. For the analyzer to display these values, the TMO2 must include external compensation.

  • Page 35: Set Communications

    The baud rate can be changed using a terminal connected to the RS-232C port. However, this is not recommended, as the TMO2D will immediately change to the new baud rate. Display and keyboard operation will not be correct until the baud rate of the terminal is changed to match the new baud rate set in the TMO2D.
  • Page 36 SET COMMUNICATIONS Press [NO] to proceed to the next submenu. Set Time Stamp? SET COMMUNICATIONS Press [YES] to return to the main Setup Menu. Done? SETUP Menu Press [NO] to proceed to the next submenu. Set Communications? TMO2D User’s Manual...

  • Page 37: Set Error Handling

    The Set Error Handling? submenu enables the TMO2D to handle inputs it receives that are outside its measurement range. Based on directions it receives, the TMO2D can show the errors on the display and force an output high or low.

  • Page 38: The Outputs Menu

    The TMO2D provides a choice of one isolated 0/4-20 mA output, or two isolated 0/4-20 mA outputs. You can set both options for a 0 to 20-mA or a 4-20 mA response, and scale the output anywhere within the range of the transmitter.

  • Page 39: The Relays Menu

    The Relays Menu The third main menu is the Relays Menu. The TMO2D includes two or four single-pole double throw (SPDT) relays for use in activating alarm devices or driving automatic calibration solenoid valves. The display addresses the relays as A, B, C or D.

  • Page 40: Autocalibration Type

    [ALARM] autocalibration 4.6.1 Autocalibration Type If you select Autocalibration, the TMO2D asks for the Auto-Calibration option: Auto-Cal Relay Type: Use the [NO] or arrow keys to select the autocalibration type, and press [YES] to confirm the selection. [PROC/CAL] zero/span For either selection, the program returns to the Select Relay to Set? entry.
  • Page 41 Press [NO] to proceed to the cal error action entry. Set System Fault Action? The calibration error could occur if the TMO2D performs an autocal on a transmitter and the amount of drift exceeds a programmed limit. You can set the limits in Change AutoCal Limits? on page 61.
  • Page 42 The Cal occurred alarm trips if autoverification is enabled and an automatic calibration is performed on a transmitter. If the amount of drift exceeds the limits programmed, the TMO2D stores the new drift calibration data and trips an alarm to indicate the change. For further details, refer to page 43 and Change AutoCal Limits? on page 61.

  • Page 48 4.8.3.2 Pressure Compensation: In the TMO2D, pressure (PRES) compensation is typically used only with a TMO2 oxygen transmitter. Pressure compensation will correct the oxygen readings for any changes in atmospheric pressure. If you have selected pressure compensation, you must enter both transducer data and pressure grid data.

  • Page 49: Pressure Calibration

    Pressure Calibration? The Pressure Calibration? submenu enables users to directly calibrate the pressure transducer. While this menu option is always displayed, it should only be programmed and used when the TMO2D is used with a TMO2 calibrated for atmospheric pressure compensation.

  • Page 50: Auto Cal Parameters

    At the specified time interval, the TMO2D activates a solenoid valve on a sampling system using one of the relays provided. This procedure isolates the transmitter from the process stream and connects the transmitter to one of the calibration gases.
  • Page 51 Auto verification is similar to automatic calibration. The solenoids are still tripped to allow the calibration gases to flow to the transmitter. However, if the calculated drift is less than a preprogrammed amount, the TMO2D will not store the new drift data into memory. If the drift is beyond the verification limit and no cal error occurs, then the TMO2D applies new calibration data and sets a new calibration flag.
  • Page 52 Use the [NO] or arrow keys to select enabling or disabling of auto cal verification. Press [YES] to confirm your entry. disabled [ENABLED] AUTO CALIBRATION MENU Press [NO] to proceed to the Time Interval option. Set Auto Verification? TMO2D User’s Manual...

  • Page 54 For example, to set the zero gas in a 2-gas cal mode for 0.00% oxygen for an equilibration time of 3 minutes: AUTO CALIBRATION MENU Scroll through the submenu, and press [YES] to enter the Set Zero Gas option. Set Zero Gas? TMO2D User’s Manual...
  • Page 55 AUTO CALIBRATION MENU Press [NO] to proceed to the Set Settling Time option. Set Span Gas? In the 1-gas cal mode, entering offset gas data is similar to entering the zero or span gas data described Note: above. TMO2D User’s Manual...
  • Page 56 TMO2D resumes taking measurements and reactivates the recorder output. (During an autocal, the recorder output from the TMO2D has been locked to the last value it had sent directly before the autocal began.) AUTO CALIBRATION MENU Scroll through the submenu, and press [YES] to enter the Set Settling Time option.

  • Page 61: The System Log Menu

    Testing the fault alarm does not appear in the System Log. The TMO2D stores only the 25 most recent events in its memory. When additional events occur, the TMO2D discards the oldest event from the log to make room for the new event. Refer to Figure 29 on page 85, for a flow diagram of the System Log menu.

  • Page 62: Viewing The System Log

    The System Log may be viewed on the TMO2D display, or transmitted to a computer, printer or other data acquisition system using the RS232 serial port. To view the System Log on the TMO2D display, scroll through the Main Menu until...

    Chapter 5. Advanced Programming 5.1 Introduction In addition to its basic program, the TMO2D analyzer contains a factory setup program that enables the user to perform more advanced operations on the parameters that have been first installed at the factory. This program has eight main menus.

  • Page 66: Set Significant Digits

    Note: This option applies only if you select display in ppm ranges. If the TMO2D is set up for the 10 ppm range, it defaults to 2-digit resolution. However, you can change the significant digits in this menu.
