2.1Product safety
WARNING
EXPLOSIONS
The Rosemount OCX8800 may explode if used in hazardous areas.
The Rosemount OCX88A can be installed in general purpose areas only.
Do not install the Rosemount OCX88A in hazardous areas.
To maintain explosion-proof protection of the Rosemount OCX88C in
hazardous areas, all cable entry devices and blanking elements for
unused apertures must be certified flameproof, suitable for the
conditions of use, and properly installed.
To maintain explosion-proof protection of the Rosemount OCX88C in
hazardous areas, the sensor housing must not be mounted to any
surface or flange that exceeds 383 °F (195 °C).
To maintain explosion-proof protection of the Rosemount OCX88C in
hazardous areas, the sample entering the sensor housing must not
exceed 383 °F (195 °C).
WARNING
PHYSICAL ACCESS
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or
unintentional and needs to be protected against.
2.2Mechanical installation
2.2.1Select a location
The location of the transmitter in the stack or flue is important for maximum
accuracy in the oxygen analyzing process. You must position the probe so
the gas it measures is representative of the process.
For best results, position the transmitter near the center of the duct (40 to
60 percent insertion). Longer ducts may require several transmitters since
the oxygen and combustibles can vary due to stratification. A point too near
the wall of the duct or the inside radius of a bend may not provide a
representative sample because of the very low flow conditions. Select the
sensing point so the process gas temperature falls within the range of probe
material used. #unique_11/unique_11_Connect_42_fig_rds_cc3_5jb

February 2020Quick Start Guide
through #unique_11/unique_11_Connect_42_fig_a2b_pl3_5jb provide
mechanical installation references.
CAUTION
Damage to the electronics may result.
Do not allow the temperature of the electronics housing to exceed 185 °F
(85 °C).
CAUTION
Failure to connect the pneumatic lines can allow the flow of contaminants
into the transmitter's ports.
Whenever a positive stack pressure exists at the installation site, be sure to
connect all pneumatic lines prior to installing the transmitter in the stack or
ductwork.
Procedure
1. Check the flue or stack for holes and air leakage.
The presence of this condition will substantially affect the accuracy of
the oxygen and combustibles readings. Make the necessary repairs
or install the transmitter upstream of any leakage.
2. Ensure the area is clear of internal and external obstructions that will
interfere with installation and maintenance access to the transmitter.
Allow adequate clearance for the removal of the transmitter.
2.2.2Install
Procedure
1. Ensure all components are available to install the transmitter.
You may install the transmitter intact as it is received.
2. Weld or bolt adapter plate onto the duct.
3. Use the pipe or wall mounting hardware as shown in #unique_11/
unique_11_Connect_42_fig_tlq_kf3_5jb to mount a remote
electronics housing.
Choose a location that does not exceed the length of the electronics
cable ordered.
4. Ensure the conduits drop vertically from the transmitter and the
conduit is routed below the level of the conduit ports on the housing
to form a drip loop.
Quick Start Guide5
Quick Start GuideFebruary 2020
Drip loops minimize the possibility that moisture will damage the
electronics.
5. Where a positive stack pressure exists at the installation site, connect
all pneumatic lines prior to installing the transmitter in the stack or
ductwork.
CAUTION
If process temperatures will exceed 392 °F (200 °C), use anti-seize
compound on stud threads to ease future removal of the transmitter.
6. Insert sample and exhaust tubes through the opening in the
mounting flange and bolt the unit to the flange.
CAUTION
Uninsulated stacks or ducts may cause ambient temperatures in the
electronics housing to exceed 185 °F (85 °C) and damage the
electronics.
If insulation is removed to access the duct for mounting the
transmitter, make sure to replace insulation afterward.

3Configuration and startup
WARNING
Failure to install covers and ground leads could result in serious injury or
death.
Install all protective equipment covers and safety ground leads after
installation.
3.1Verify installation
Ensure the transmitter is installed correctly. Verify mechanical installation
and all electrical and pneumatic connections.
CAUTION
Damage can result from having a cold transmitter exposed to the process
gases.
Make sure that the transmitter is turned on and operating prior to firing
up the combustion process.
During outages, and whenever possible, leave all transmitters running to
prevent condensation and premature aging from thermal cycling.
3.1.1Verify configuration - HART® electronics
There are three switches on the microprocessor board which are user
configurable for the Rosemount OCX8800 with HART electronics (Figure
3-1).
SW1 determines if the O2 4-20 mA signal is internally or externally powered.
SW2 determines if the COe 4-20 mA signal is internally or externally
powered. SW3 sets the rail limits for the O2 and COe 4-20 mA signals and
configures the sample line heater control circuit. All switches are accessible
through holes in the electronics box.
CAUTION
If defaults are changed under power, damage to the electronics may occur.
Remove power from the transmitter before changing defaults.
Verify that the following switch settings are correct for your installation:
A. Switch default positions shown
B. O2 21.1 mA / 3.5 mA: O2 4-20 mA signal
Rail limits:
Open High: 21.1 mA
Closed Low: 3.5 mA
COe 21.1 mA/3.5 mA: COe 4-20 mA signal
Rail limits:
Open High: 21.1 mA
Closed Low: 3.5 mA
C. Internal: COe 4-20 mA is internally powered.
D. External: COe 4-20 mA requires an external power supply (default).
E. Internal: O2 4-20 mA is internally powered.
F. External: O2 4-20 mA requires an external power supply (default).
SW1: The two settings are internally or externally powering the O2 4-20 mA
signal. The factory setting is for the O2 4-20 mA signal to be internally
powered.
28Emerson.com/Rosemount
February 2020Quick Start Guide
SW2: The two settings are internally or externally powering the COe 4-20
mA signal. The factory setting is for the COe 4-20 mA signal to be internally
powered.
SW3: The factory sets this switch as follows:
• Position 1 determines the O2 4-20 mA signal rail limit. The settings are
high, 21.1 mA, or low, 3.5 mA. The factory setting is low, 3.5 mA.
• Position 2 determines the COe 4-20 mA signal rail limit. The settings are
high, 21.1 mA, or low, 3.5 mA. The factory setting is high, 21.1 mA.
Positions 3 and 4 must be set as shown for proper software control of the
device heaters.
3.2Initial power up
Allow adequate time (approximately 60 minutes) for the heaters to begin
operation and for the transmitter to reach normal operating temperature on
power up.
Normal operating temperature for the O2 cell is 1357 °F (736 °C). Normal
operating temperature for the combustibles cell is 572 °F (300 °C). The
normal sample line temperature is 338 °F (170 °C). During this time, the
eductor air solenoid will remain closed, so no sample is pulled through the
transmitter. When the transmitter reaches operating temperature, the
solenoid will energize, eductor air will begin to flow, and the transmitter will
begin normal operation.

3.6COe purge/zero feature
This feature provides a way to periodically flood the COe sensor with air to
perform two functions:
1. Provide additional oxygen to help burn off any combustible residue
from the COe sensor.
2. Allow for optional adjustment of the COe calibration constant.
If the transmitter is configured to update the COe calibration constant, only
the constant is updated. The COe calibration slope is not affected. To update
both the constant and slope, you must do a full calibration.
The feature uses the calibration solenoid that is also used for high O2 test gas
and COe zero gas. For the feature to work properly, instrument air is used as
the high O2 test gas. This also requires the high O2 test gas value to be set at
20.95 percent. You can install a two-way valve to switch the high O2 test gas
between the normal calibration gas and instrument air. This allows the
transmitter to use a specified calibration gas for calibration, then instrument
air for the COe zero feature. Switching between the two gases must be
manually coordinated between scheduled calibrations and COe zero events.
When the COe zero feature is used, special pneumatic connections are
required.
The COe zero feature is only valid if the transmitter is supplied with
calibration solenoids and the solenoids have been activated.
A Rosemount OCX8800 shipped from the factory must be configured before
the COe zero feature can be implemented. This same process must be
performed any time a replacement card stack is installed.
WARNING
During the COe Zero Function, the analog output signals may track the
oxygen and combustibles readings if configured to do so.
To avoid a potentially dangerous operating condition, remove the
transmitter from the automatic combustion control loop before performing
the COe Zero Function procedure.
Note
At the completion of the COe Zero Function, the COe analog output signal
will change if the Zero Update parameter is set to Yes.
