The Xi electronics has several main functions:
1. Heater Control - The electronics receives a type K thermocouple input
from an O
probe and switches power on and off to the probe's heater in

order to maintain a temperature setpoint of 736 degrees C.
2. Signal Conditioning - The electronics receives the raw millivolt signal
from the O
sensing cell, then linearizes and amplifies the signal to
2
provide a linear 4-20 mA output signal used for recording or as an input
into a DCS system for control purposes.
3. Calibration - A bottled calibration gas of known value is typically flowed
into the probe's sensor to verify that it is reading correctly. If the signal is
out of calibration, the calibration gas is used to adjust the 4-20 mA
output signal. During calibration the Xi prompts the technician to flow
two calibration gases into the probe and, with the calibration gases
flowing, automatically adjusts the O
signal. With the addition of a Single
2
Probe Sequencer (SPS), the Xi electronics can also switch the
calibration gases on and off.
4. Diagnostics - Multiple alarms are available for display. The alarm
displays are intended to assist a technician in locating where an
instrument problem may reside.
The Xi electronics has been verified to operate the following probes:
• Westinghouse 218 and World Class
• Rosemount Analytical Oxymitter
• Yokogawa

System ConfigurationsTraditional Architecture, HART and Xi Communications
Some customers prefer not to mount electronics onto the probe, so a
"traditional architecture" version is offered. This probe sends raw millivolt
signals via a 7-conductor cable to the Xi electronics, Figure 1-2, which does
all heater control and signal conditioning in addition to its display/keypad
functions. The Xi Advanced Electronics is offered to support direct replacement probes with either 120 volt or 44 volt heaters.

Automatic Calibration
Communication Options
Calibrations consist of introducing bottled gases of known value into the probe
so the electronics can make automatic adjustments to the O2 readings to
match the bottled gas value. 0.4% O2 and 8% O2 (balance nitrogen) gases
are recommended. Never use nitrogen or instrument air as calibration gases.
Flowmeters (for calibration gases) and regulators and flowmeters (for
reference air) are available as loose components, mounted into an optional
manual calibration switching panel, or as a fully automatic calibration system,
Figure 1-3, where calibration solenoids are switched from the Xi Electronics.
See IM-106-340AC, SPS 4000B Single Probe Autocalibration Sequencer or
IM-106-400IMPS, IMPS 4000 Intelligent Multiprobe Test Gas Sequencer, for
additional details.
Data Communications
An operator can configure and troubleshoot the O2 Probe system in one of
two ways:
1. Using the Xi Advanced Electronics the Xi carries the following optional
advanced features:
• Fully automatic calibration
• Flame safety interface
• High temperature operation [above 700°C (1292°F) standard
temperature].
• Stoichiometer feature provides the ability to indicate O2 efficiency
when the combustion process goes into reducing conditions
(0% O2).
• Programmable reference provides enhanced accuracy when
measuring at or near O2 level (20.95% O2).
2. Using the HART Interface. The Xi’s 4-20 mA output line transmits an
analog signal proportional to the oxygen level. The HART output is
superimposed on the 4-20 mA output line. This information can be
accessed through the following:
• Rosemount Analytical Model 375/475 Field Communicator - The
handheld communicator requires Device Description (DD) software
specific to the Xi. The DD software will be supplied with many Model
375/475 units but can also be programmed into existing units at most
Emerson Process Management service offices. See Section 4,
Startup and Operation, for additional information.
• Personal Computer (PC) - The use of a personal computer requires
AMS software available from Emerson Process Management.
• Delta V and Ovation Distributed Control System (DCS) with
AMS-inside capability.

NOTE:
The 375 Field Communicator must be upgraded to System Software 2.0 with
Graphic License for operation with the Xi. The AMS software must be
upgraded to AMS 8.0 or above.
Contact Emerson Process Management’s Global Service Center (GSC) at

3. The Xi can also transmit HART information wirelessly via a wireless
THUM Adapter, Figure 1-4. The THUM Adapter threads into the Xi
conduit port and converts the 4-20 mA O2 signal to a wireless protocol.
All other HART information is also transmitted.
In addition to the wireless THUM Adapter, a hard-wire connection of the
4-20 mA signal to the DCS may be used at the same time. More
detailed information regarding the application of the THUM Adapter is
available in Product Data Sheet 00813-0100-4075. Note that the THUM

INSTALLATION
Xi Advanced Electronics
All wiring must conform to local and national codes. Multiple wiring diagrams
are shown in this section. Always refer to the diagrams that apply to your
transmitter configuration and disregard all other wiring diagrams.
Disconnect and lock out power before connecting the power supply.
Install all protective covers and safety ground leads after installation. Failure to install covers
and ground leads could result in serious injury or death.
To meet the Safety Requirements of IEC 1010 (EC requirement), and ensure safe operation
of this equipment, connection to the main electrical power supply must be made through a
circuit breaker (min 10A) which will disconnect all current-carrying conductors during a fault
situation. This circuit breaker should also include a mechanically operated isolating switch.
If not, then another external means of disconnecting the supply from the equipment should
be located close by. Circuit breakers or switches must comply with a recognized standard
such as IEC 947.
NOTE
Line voltage, signal, and relay wiring must be rated for at least 105
°C
(221°F).
NOTE
If metal conduit is used with the Xi the conduit should be reliably bonded to
protective earth. The grounding plate inside the Xi is not bonded to PE and
does not provide adequate grounding.
1. Remove cover screws from the front cover of the Xi. Swing down the
front cover of the interface box.
2. Pull out the I/O board on the right-hand side of the card rack inside the
Xi. If your system is configured to operate two transmitter probes there
are two I/O interface boards.
3. See Figure 2-4. Connect the 4-20 mA signal wires at J4 of the I/O
board. Attach the supplied ferrite clamp over the 4-20 mA OUT wires
that extend past the shield.
NOTE
Installation of the ferrite clamp over the 4-20 mA OUT wires is required for
compliance with the European EMC Directive.
