Environmental Compliance
Waste Electrical and Electronic Equipment (WEEE) Directive
GE Measurement & Control Solutions is an active participant in Europe’s Waste Electrical and Electronic Equipment
(WEEE) take-back initiative, directive 2002/96/EC.
The equipment that you bought has required the extraction and use of natural resources for its production. It may
contain hazardous substances that could impact health and the environment.
In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the natural
resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle most of the
materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please contact your local or regional
waste administration.

Chapter 2. Installation
Chapter 2. Installation
2.1 Overview
This chapter describes how to mount and wire the TMO2D Digital Display. It also contains information on con nect i ng
the TMO2D to optional system components. The following topics are discussed:
• Mounting the TMO2D digital display.
• Wiring various GE transmitters to the TMO2D display.
• Connecting to other components.
WARNING!
To ensure the safe operation of the TMO2D, it must be installed and operated as described in
this manual. In addition, be sure to follow all applicable safety codes and regulations for
installing electrical equipment in your area. All installation procedures should be performed by
trained service personnel.
2.2 Mounting the Electronic Display
The electronic display comes in six mounting configurations: bench, rack, panel, fiberglass NEMA 4X, 304 stainless
steel NEMA 4X and explosion-proof. (See Appendix A for mounting dimensions).
No special mounting requirements are needed for the display. If you have a bench mount, simply put the display in a
convenient location, connect the wires from the transmitter, and connect the power. If you have a rack or panel mount,
insert the display into the rack or panel, connect the wires from the transmitter, and connect the power. The
weatherproof and explosion-proof models are wall mounted.
IMPORTANT: For compliance with the EU’s Low Voltage Directive (2006/95/EC), this unit r equires an external power
disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such,
clearly visible, directly accessible, and located within 1.8 m (6 ft) of the unit. The power cord is the main
disconnect device.
2.3 Wiring Transmitters to the TMO2D Display
This section explains how to interconnect the TMO2D display with four different GE transmitters: TMO2, XMO2,
TMO2-TC and XMTC.
2.3.1 TMO2 Transmitter
This section describes how to interconnect the TMO2 and TMO2D. The TMO2 can be wired for internal or external
compensation. Each type of compensation requires a different cable. Before you make any connections, make sure you
have the appropriate cable. Please check the TMO2 calibration sheet to determine if your TMO2 has internal or
external compensation.
• Internal compensation offers a single 4–20mA output for O
ba
ckground gas or atmosp
heric pressure variations.
• External compensation offers dual 4–20mA outputs, one for uncompensated O

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.
3.3 The User Interface
The electronic display unit contains a 2-line by 24-character backlit Liquid Crystal Display screen (LCD). On
power-up, the display unit tests its memory (RAM), then searches for valid calibration data from the display as well as
input from the transmitter.
If calibration data has already been entered into the display, the unit immediately begins taking measurements from the
transmitter and the LCD begins displaying the gas concentration.
If valid calibration data has not been entered and stored in the display, or if the transmitter is not hooked up to the
display , the LCD will display erroneou s readings. (Chapter 4, Pr ogramming the TMO2D Display, explains how to enter
data into the display.)
The TMO2D is operated using the keypad. To facilitate operation, you should familiarize yourself with the display and
keypad functions.
3.3.1 The LCD Display
The first line of the LCD screen displays the current measurement or menu title and a real-time clock. The second line
of the LCD screen displays the measured data on the left and the current alarm condition on the right.
Note: The LCD contains an electroluminescent (EL) panel to enhance readability of the screen during operation. To
activate the EL panel, press any key except the [NO] key.

4.1 Introduction
The TMO2D display contains an interactive, user-friendly program that enables the user to change operating
parameters as desired.
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. New data overrides any previously entered data.
The user program consists of six main menus:
• Setup
• Outputs
• Relays
• Tests
• Calibration
• System Log
Note: The TMO2D can function as a display package for a variety of GE transmitters. As an example, this chapter
describes TMO2D programming when the TMO2D is used with a TMO2 or XMO2 oxygen transmitter.
4.2 Entering Data into the User Program
To enter data into the user program or to check previously entered values, enter the Menu Mode. When the power is
turned on, the TMO2D enters the Operate Mode. To enter the Menu Mode:
1. Press the [NO] key.
2. Key in the code [1] [2] [3]. The TMO2D will display an asterisk (*) after you enter each digit.
If an incorrect code is entered or a non-numeric ([YES]/[NO] or arrow) key is pressed rather than 1 2 3, the LCD will
automatically resume displaying data, and you must press [NO] to re-attempt the code. Once all three digits have been
entered correctly, the display will cease collecting data and the LCD will switch to Menu Mode.
The LCD screen now displays the Setup Menu, the first of the six main menus. At this display, press [YES] to enter this
menu, or [NO] to scroll to the next menu. Pressing [NO] repeatedly scrolls through all six main menus.
Note: The first six options are main menus, while the RESUME prompt enables users to exit the Menu Mode and
return to Operate Mode.
TMO2D Digital Display User’s Manual 21
Page 30
Chapter 4. Basic Programming
4.2.1 Key Functions
The [YES] key enables you to confirm numeric entries or to select a displayed menu option.
The [NO] key enables you to clear a numeric entry or to scroll forward through the menu options.
The [] key has two functions:
• It serves as a backspace key during numeric entry. At each press of [], the display erases the last digit on the right
of the entry.
• It also enables you to step backward through a list of menu options.
The [] key enables you to scroll forward through the menu options; it is equivalent to pressing the [NO] key in the
Menu Mode.
4.3 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.
4.3.1 Display Navigation
On power-up, the first line of the LCD screen contains the current measurement parameter and a real-time clock. The
second line of the LCD contains the measured data on the left and the current alarm condition on the right (see
Figure 13 below).
Figure 13: TMO2D Display
While displaying the gas concentration, the display will ignore all keys except the [NO] key. If you press [NO], the
LCD will begin displaying Enter Code: and you must enter the program entry code ([1] [2] [3]). During code entry, the
display continues to update the data display, alarm status, and recorder output.
22 TMO2D Digital Display User’s Manual
Page 31
Chapter 4. Basic Programming
4.3.2 Menu Navigation
After you enter the passcode, the LCD switches to Menu Mode, which enables you to program the display, setting
parameters and calibration data as well as performing relay and output tests. While in Menu Mode, the display
suspends data collection, and relay status and outputs hold their current va lues.
In Menu Mode, the first line of the LCD shows the title of the current menu in capital letters. The second line displays
the current menu options.
Enter data in the Menu Mode through the [YES]/[NO] and Selector ([] and []) keys. Pressing [YES] selects the
displayed option, while pressing [NO] skips that option and displays the next option in the list. The Selector keys
enable users to choose between two or three possible options in the menu.
Note: The menu lists are circular; skipping over the last option in the list returns you to the first option in the list.
The following sections describe the programming procedure and menu navigation in detail, one menu at a time.
(Appendix B supplies flow diagrams of each menu.)
4.4 The Setup Menu
The Setup Menu contains eight submenus:
• Set Time?
• Set Date?

options for a 0 to 20-mA or a 4-20 mA response, and scale the output anywhere within the range of the transmitter.
Note: The displ ay is programmed to accept settings for two outputs; however, if only a single isolated output is used,
only output A is effective.
The steps in the following example illustrate how to set up outputs. In this instance, output A will have a 0 to 20-mA
range, with 0 mA equal to 0% oxygen and 20 mA equal to 100% oxygen. (Appendix B offers a flow diagram of the

4.6 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. You can configure each relay as either an alarm or as an automatic calibration relay.
If the relay is configured as an alarm, it can be programmed to trip on up to five functions, listed below, and in either
Failsafe or Non-Failsafe mode:
• Low Gas Reading
• High Gas Reading
• System Fault Indicator
• Auto Calibration Error Indicator
• New Auto Calibration Data
If the relay is configured as an Auto-Calibration relay, the TMO2D offers two options:
• Process/Cal Relay
• Zero/Span Relay
If the transmitter requires a one gas offset or one gas span calibration, you need to set only one relay for
Auto-Calibration, with the Process/Cal option. However, if it requires a two-gas zero and span calibration, you must set
two relays for Auto-Calibration, one to Process/Cal and the other to Zero/Span.

4.8.5 Auto Cal Parameters
You can program the TMO2D to perform an automatic calibration procedure (Auto Cal) at specified time intervals
ranging from minutes to months.
By performing measurements on either one calibration gas (offset or span) or on two calibration gases (zero and span),
the unit can correct for changes in the response of the transmitter without operator intervention.
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. After a programmable time, during which the calibration gas replaces the process gas, the transmitter
takes measurements of the calibration gas.
The analyzer then activates a second solenoid valve, using a second relay, to connect the transmitter to the other
calibration gas. The transmitter then equilibrates as the second calibration gas replaces the first gas, and takes
measurements of the second calibration gas.
After taking span and zero gas measurements, the TMO2D reconnects the transmitter to the process stream. Then a
final settling time takes place while the process gas replaces the calibration gas.
Once settling has been completed, if no error has occurred, the analyzer calculates the amount of drift and applies the
calculated drift to the factory calibration data. The factory calibration data remains unchanged. The TMO2D stores the
corrections to the calibration data as the Drift Curve.
If the Auto Cal measurements are beyond the preprogrammed limit, the unit disregards the data and uses the drift curve
already stored in memory. If you have enabled Auto Cal Error Handling (see page 47), the display and outputs will
respond as programmed. If any alarm relays have been assigned to trip on Auto Calibration Errors, they will be tripped.
Contact the factory to expand the AutoCal drift limits. The default limits are 25% of full scale per calibration and 40%
of full scale total drift.
Alternately , the automatic calibration can be performed in an of fset or span correction manner using a single calibration
gas and one solenoid valve. When calibration is active, the autocalibration status replaces the display of pressure or
background:
• Cal:ok (no errors and no new cal data applied)
• Cal:new (no errors and new data applied)
• Cal:err (total or per reading drift error)

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.

4.8.5b Set Time Interval?
The Set Time Interval? option enables you to set the time interval at which an Auto Cal or Verification will occur.
Set Time Interval? enables you to set an interval of either hours or days. You can enter hours as fractions
(i.e., 90 minutes = 1.5 hours), up to a maximum of 24 hours.
Days can range from 0 to 99; however, the display does not accept fractional days. An interval of zero days prevents
Auto Cal from occurring. (You can still perform a manual field calibration through the Perform AutoCal option.) If you
enter a number of days (other than zero), the display will prompt for the time of day when the Auto Cal should occur.
For example, to set the time interval for 12 hours:

Most transmitters will have the best accuracy with a two-point zero and span calibration. Transmitters such as the
O2X1 oxygen transmitter have a fixed zero point, so only a one-gas span (slope) calibration is required. Set AutoCal
Mode? enables you to determine whether the display calibrates for both zero and span gases (two points) or simply for
one gas, either on offset or span (slope). To enter this option:

4.8.5d Set Cal Gas Data?
In the “Set Cal Gas Data?” option, you can program the zero, span or offset gases. If you select the “2 gas cal” mode,
the prompts ask for zero and span gas data. But if you select the “1 gas cal” mode, the prompt asks for data for either
the offset or span gas, depending on the mode selected in the Set AutoCal Mode? on page 45.
For an oxygen transmitter, if 100% nitrogen is used for the zero gas, the concentration would be zero. If a mixture is
used, you should enter the oxygen concentration of the mixture. The default concentration is 0% oxygen.
After you enter the gas concentration, the display will automatically prompt for the equilibration time for the zero gas.
The equilibration time should allow for the distance the calibration gas must travel, and for the settling time of the
transmitter cell.
Note: For a successful auto calibration, the equilibration time should be at least
3 minutes.The default is 5 minutes.
For testing purposes, the equilibration time can be as low as 0 seconds. The maximum equilibration time is 90
minutes.
For example, to set the zero gas in a 2-gas cal mode for 0.00% oxygen for an equilibration time of 3 minutes:

4.9 The System Log Menu
The TMO2D maintains a System Log in battery-backed memory. Among other things, this log indicates the nature of
any fault signaled by the fault alarm relay by recording the type, date, and time of the relevant events.
The System Log can record up to 25 events of the following types:
• factory initialization
• system power on
• system RESET
• RAM checksum failure (memory corruption)
• Transmitter cell under range
• Transmitter cell over range
• no calibration curve
• return to normal operation
• AutoCal Tot drift error
• AutoCal Drift/Cal error
Note: 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 82, for a flow diagram of the

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. Use the front panel keypad and display to check or change the settings for current operating parameters. New
data overrides any previously entered data.
IMPORTANT: Consult GE before changing any parameters in this menu.
The user program consists of eight main menus:
• Set Significant Digits
• Select Background
• Select Tracking
• Select Tertiary
• Response Parameters
• Labcal Outputs
• Manual Offset
• Change AutoCal Limits
5.2 Entering Data into the Factory Setup Program
To enter data into the program or to check previously entered values, enter the Factory Setup Menu Mode. When you
turn the power on, the TMO2D enters the Operate Mode. To enter the Factory Setup Menu Mode:
1. Press the [NO] key.
2. Key in the code [3] [6] [9]. The TMO2D will display an asterisk (*) after you enter each digit.
If you enter an incorrect code or press a non-numeric ([YES]/[NO] or arrow) key rather than 3 6 9, the LCD will
automatically resume displaying data, and you must press [NO] to re-attempt the code. Once all three digits have been
entered correctly, the display will cease collecting data and the LCD will switch to the Factory Setup Menu Mode.
The LCD screen now displays the Set Significant Digits? menu, the first of the eight main menus. At this display, press
[YES] to enter this menu, or [NO] to scroll to the next menu. Pressing [NO] continuously scrolls through all eight main
menus. Refer to Figure 30 on page 83 for a flow diagram of the Factory Setup Menu.
