Mount remote display

Complete the following steps to install the Rosemount CX1100 Remote Transmitter.

Install

The Rosemount CX1100 Remote Transmitter is available in a panel mounting or wall/pipe
mounting configuration. Refer to Figure 1-4 or Figure 1-5 for the panel, wall, or pipe
mounting details. You need a wrench and bolts to mount the transmitter.

Procedure

1. Ensure all components are available to install the Rosemount CX1100 Remote
Transmitter.

2. Select a mounting location near or removed from the Rosemount CX1100 Probe.

Consider the temperature limitations of the Rosemount CX1100 Remote
Transmitter. Refer to product specifications when selecting the mounting location.

3. Mount at a height convenient for viewing and operating the interface.

Emerson recommends approximately 5 ft. (1.5 m).

4. The keypad window on the Rosemount CX1100 Remote Transmitter may have an
exterior protective membrane. Remove the protective membrane prior to use of the
Rosemount CX1100 Remote transmitter.

Failure to remove the protective membrane may cause the display to appear
distorted. The membrane may become difficult or impossible to remove after
extended use at elevated temperatures.

Wire

2 Wire

All wiring must conform to local and national codes.

WARNING!

Before installing the equipment, read the Safety Instructions at the front of this manual. Failure
to follow safety instructions could result in serious injury or death.

NOTICE

To maintain proper earth grounding, ensure a positive connection exists between the probe
terminations housing and earth. The connecting wire must be 14 AWG minimum.

NOTICE

Line voltage, signal, and relay wiring must be rated for at least 221 °F (105 °C).

2.1

2.2

NOTICE

If metal conduit is used with the Rosemount™ CX1100 Remote Transmitter, reliably bond the
conduit to protective earth. The grounding plate inside the Rosemount CX1100 Remote
Transmitter is not bonded to PE and does not provide adequate grounding.

Installation specifications - interconnect cable

Customer supplied cable up to 200 ft. (60 m) long, rated for -40 to 194 °F (-40 to 90 °C)
and voltage 300 VACrms.

Heater power: 3 multi conductor 18ga shielded cable to connect the heater control signal

Probe sensing: 3 twisted pair conductors 22ga overall shielded cable to connect the TC,
O2, and CJC signals.

Cable may be purchased as two separate cables.

Connect the cables

Raw voltages from the oxygen sensor and heater thermocouple are transmitted from the
Rosemount CX1100 Probe to the Rosemount CX1100 Remote Transmitter. The remote
transmitter also controls power to the probe heater in order to maintain the correct sensor
temperature.
This arrangement calls for interconnect wiring consisting of nine conductors. Given the
recommended wire specifications, the maximum length for this cable is 200 ft (60 m)
(refer to Section 2.1).

8 Rosemount™ CX1100

Wire

NOTICE

To maintain EMC/EMI noise protection, connect the customer supplied 9 conductor cable and
cable glands properly to ground.

Procedure

1. Run the signal and power cables between the probe and the installation site for the
optional Rosemount CX1100 Remote Transmitter.

2. Remove the covers from the probe and the remote transmitter (if applicable).

3. Feed all probe wiring through the conduit port of the probe.

4. Refer to Figure 2-2. Connect probe heater power leads to probe connector.

5. Connect O2 signal, thermocouple, and cold junction (CJC) wires from probe to the
Rosemount CX1100 Remote Transmitter.

6. At the Rosemount CX1100 Remote Transmitter, connect the cable leads to the
connectors on the sensor board as indicated in Figure 2-1.

3 Startup

1. Apply AC line power to the Rosemount™ CX1100 Remote Transmitter.

The probe takes approximately 45 minutes to warm up to the 1357 °F (736 °C)
setpoint. The 4-20 mA signal remains at a default value of 3.5 mA, and the O
reading remains at 0% through the warmup period.

2. After warmup, the probe begins reading oxygen, and the 4-20 mA output is based
on the default range of 0-10% O2.

If there is an error condition at startup, an alarm message is displayed on the
Rosemount CX1100 Remote Transmitter.

Calibration

4 Calibration

The Rosemount™ CX1100 In Situ Oxygen Transmitter can be calibrated in the installed
position without removing the instrument from the process duct and also while the
combustion process is online.Gas is applied to the sensor through the calibration gas
fitting. New Rosemount CX1100 In Situ Oxygen Transmitter systems are factory calibrated
and are generally acceptable for initial startup and operation. High accuracy can be gained
by calibrating a system during normal operating conditions. Emerson ™recommends
calibrating on a semi-annual to annual basis for most applications; however actual
calibration frequency may vary per process unit.

Calibrations are conducted using a two point calibration. Factory calibration uses 0.4% O
and 8.0% O2 gases with a balance of nitrogen and is therefore recommended. Calibration
gases with other oxygen concentrations are acceptable. If using different calibration gas
values, additional configuration through the Rosemount CX1100 Remote Transmitter is
required. Emerson does not recommend pure nitrogen as a calibration gas. Use a two­stage pressure regulator to establish a pressure of 20 psi from the bottles and set the
flowmeter to 5 scfh (2.5 L/min) flow rate.

4.1 Procedure

The calibration of the Rosemount CX1100 Probe is initiated from the Rosemount CX1100
Remote Transmitter. The Rosemount CX1100 Remote Transmitter display prompts you
with the calibration instructions.

1. Press the x1 or x2 menu button on the Rosemount CX1100 Remote Transmitter
display to enter the probe.

2. Navigate, using Up and Down buttons to Setup; press Enter.

3. Navigate to Cal Gas values; press Enter.

4. Navigate to Cal Gas 1 and press Enter twice to highlight the value setting.

5. Use the Up and Down buttons to set Cal Gas 1 value and Left and Right buttons
to move to decimals setting.

6. After setting the correct value, press Enter and press Left to go to the Calibration
Setup for Cal Gas 2, Gas time, and Purge time settings.

7. After setting the values (0.4% O2, 8.0% O2, and 300s are the defaults), press Left to
go up to the Calibration submenu.

8. Navigate using the Up and Down buttons to Calibration and press Enter to start.

9. Follow the instructions on the display, manually applying calibration gases (0.4% and

8.0% O2 at 5 SCFH are recommended) to the calibration port.

10. After the calibration is finished, press Left and use the Up and Down buttons the
check the current and previous 10 calibrations log.

14 Rosemount™ CX1100

Calibration

After completing the procedure, the Rosemount CX1100 software calculates new
calibration values and determines whether they meet an acceptance criteria. If successful,
the new calibration values automatically replace the previous values. In the event the
calibration values do not meet the accepted performance criteria, the existing calibration
values remain in effect, and Emerson recommends replacing the Rosemount CX1100
Probe.

CAUTION!

EQUIPMENT DAMAGE

Make sure that the calibration gas cap is replaced tightly after calibration is complete. Many
combustion processes operate at a slight negative pressure (draft pressure) and can draw
ambient air down the cal gas lines and into the sensing cell, causing a false elevated oxygen
reading. The same phenomenon is possible if the calibration gas hoses become degraded or
loose.
