Hazardous Area Oxymitter 5000

Foundation Fieldbus Technology

System Description

Foundation fieldbus is an all digital, serial, two-way communication system that interconnects field equipment such as sensors, actuators, and controllers. Fieldbus is a Local Area Network (LAN) for instruments used in both process and manufacturing automation with built-in capacity to distribute the control application across the network. The fieldbus environment is the base level group of digital networks in the hierarchy of planet networks.

The fieldbus retains the desirable features of the 4-20 mA analog system, including a standardized physical interface to the wire, bus powered devices on a single wire, and intrinsic safety options, and enables additional capabilities, such as:

• Increased capabilities due to full digital communications

• Reduced wiring and wire terminations due to multiple devices on one set of wires

• Increased selection of suppliers due to interoperability

• Reduced loading on control room equipment with the distribution of some control and input/output functions to field devices

• Speed options for process control and manufacturing applications

The Hazardous Area Oxymitter 5000 is designed to measure the net concentration of oxygen in an industrial process; i.e., the oxygen remaining after all fuels have been oxidized. The probe is permanently positioned within an exhaust duct or stack and performs its task without the use of a sampling system.

The equipment measures oxygen percentage by reading the voltage developed across a heated electrochemical cell, which consists of a small yttria-stabilized, zirconia disc. Both sides of the disc are coated with porous metal electrodes. When operated at the proper temperature, the millivolt output voltage of the cell is given by the following Nernst equation:

EMF = KT log10(P1/P2) + C

Where:

• P2 is the partial pressure of the oxygen in the measured gas on one side of the cell.

• P1 is the partial pressure of the oxygen in the reference air on the opposite side of the cell.

• T is the absolute temperature.

• C is the cell constant.

• K is an arithmetic constant.

NOTE

For best results, use clean, dry, instrument air (20.95% oxygen) as the reference air.

1-3

Hazardous Area Oxymitter 5000

When the cell is at operating temperature and there are unequal oxygen concentrations across the cell, oxygen ions will travel from the high oxygen partial pressure side to the low oxygen partial pressure side of the cell. The resulting logarithmic output voltage is approximately 50 mV per decade. The output is proportional to the inverse logarithm of the oxygen concentration. Therefore, the output signal increases as the oxygen concentration of the sample gas decreases. This characteristic enables the Hazardous Area Oxymitter 5000 to provide exceptional sensitivity at low oxygen concentrations.

The Hazardous Area Oxymitter 5000 measures net oxygen concentration in the presence of all the products of combustion, including water vapor. Therefore, it may be considered an analysis on a "wet" basis. In comparison with older methods, such as the portable apparatus, which provides an analysis on a "dry" gas basis, the "wet" analysis will, in general, indicate a lower percentage of oxygen. The difference will be proportional to the water content of the sampled gas stream.

System Configuration

Hazardous Area Oxymitter 5000 units are available in three length options, giving the user the flexibility to use an in situ penetration appropriate to the size of the stack or duct. The options on length are 457 mm (18 in.), 0.91 m (3 ft), and 1.83 m (6 ft).

The electronics control probe temperature and provide an output, that represents the measured oxygen concentration. The power supply can accept voltages of 90-250 VAC and 48/62 Hz; therefore, no setup procedures are required. The oxygen sensing cell is maintained at a constant temperature by modulating the duty cycle of the probe heater portion of the electronics. The electronics accepts millivolt signals generated by the sensing cell and produces the outputs to be used by remotely connected devices. The output is a FOUNDATION fieldbus digital communication signal.

The Oxymitter 5000 transmitter is available with an integral or remote electronics package. Two calibration gas sequencers are available to the Hazardous Area Oxymitter 5000, but they must be installed in a nonhazardous, explosive-free environment: the IMPS 4000 and the SPS 4001B (Figure 1-2).

Systems with multiprobe applications may employ an optional IMPS 4000 Intelligent Multiprobe Test Gas Sequencer. The IMPS 4000 provides automatic calibration gas sequencing for up to four Hazardous Area Oxymitter 5000 units and accommodates autocalibrations based on the CALIBRATION RECOMMENDED signal from the Hazardous Area Oxymitter 5000, a timed interval set up via fieldbus or the IMPS 4000, or whenever a calibration request is initiated.

System Features

For systems with one or two Hazardous Area Oxymitter 5000 units per combustion process, an optional SPS 4001B Single Probe Autocalibration Sequencer can be used with each Hazardous Area Oxymitter 5000 to provide automatic calibration gas sequencing. The sequencer performs autocalibrations based on the CALIBRATION RECOMMENDED signal from the Hazardous Area Oxymitter 5000, a timed interval set up in fieldbus, or whenever a calibration request is initiated.

1. The CALIBRATION RECOMMENDED feature detects when the sensing cell is likely out of limits. This may eliminate the need to calibrate on a "time since last cal" basis.

2. The cell output voltage and sensitivity increase as the oxygen concentration decreases.

Accessing the probe keypad requires opening the electronics housing. Opening the electronics housing will cause the loss of ALL hazardous permits. Opening the electronics housing in hazardous areas may cause an explosion resulting in loss of property, severe personal injury, or death. It may be required to get a hot work permit from your company safety officer before opening the electronic housing.

a. Membrane Keypad. The membrane keypad, housed within the right

side of the electronics housing, provides fault indication by way of flashing LEDs. Calibration can be performed from the membrane keypad.

b. Local Operator Interface (LOI). The optional LOI takes the place of

the membrane keypad and allows local communication with the electronics. Refer to Section 4, Configuration of Hazardous Area Oxymitter 5000 with LOI for more information.

c. FOUNDATION fieldbus Interface. The Oxymitter 5000's output

carries a signal containing the oxygen level encoded in digital format. This digital output can also be used to communicate with the Oxymitter and access all of the Oxymitter’s status information.

d. Optional IMPS 4000. The Programmable Logic Controller (PLC) in

the IMPS 4000 provides fault indications using flashing LEDs and LCD display messages. Refer to the IMPS 4000 Intelligent Multiprobe Test Gas Sequencer manual for more information.

Handling the Oxymitter

System Considerations

It is important that printed circuit boards and integrated circuits are handled only when adequate antistatic precautions have been taken to prevent possible equipment damage.

The Hazardous Area Oxymitter 5000 is designed for industrial applications. Treat each component of the system with care to avoid physical damage. Some probe components are made from ceramics, which are susceptible to shock when mishandled.

Prior to installing your Hazardous Area Oxymitter 5000, make sure you have all the components necessary to make the system installation. Ensure all the components are properly integrated to make the system functional.

After verifying that you have all the components, select mounting locations and determine how each component will be placed in terms of available line voltage, ambient temperatures, environmental considerations, convenience, and serviceability. Figure 1-5 shows a typical system wiring.

A typical system installation with integral electronics is illustrated in Figure 1-6. A typical system installation with remote electronics is illustrated in Figure 1-7.

A source of instrument air is optional at the Hazardous Area Oxymitter 5000 for reference air use. Since the unit can be equipped with an in-place calibration feature, provisions can be made to permanently connect calibration gas bottles to the Hazardous Area Oxymitter 5000.

If the calibration gas bottles will be permanently connected, a check valve is required next to the calibration fittings on the integral electronics.

This check valve is to prevent breathing of the calibration gas line and subsequent flue gas condensation and corrosion.

The check valve is in addition to the stop valve in the calibration gas kit and solenoid valves in the IMPS 4000 or SPS 4001B.

NOTE

The integral electronics is rated NEMA 4X (IP66) and is capable of operation at temperatures up to 85°C (185°F).

Mounting

If using an IMPS 4000 with a Hazardous Area Oxymitter 5000, the IMPS 4000 sequencer must be installed in a non-hazardous, explosive-free environment.

For further IMPS 4000 information, refer to the IMPS 4000 Intelligent Multiprobe Test Gas Sequencer Instruction Manual.

If using an SPS 4001B with a Hazardous Area Oxymitter 5000, the SPS 4001B sequencer must be installed in a non-hazardous, explosive-free environment.

The SPS 4001B is fully enclosed in a NEMA cabinet suited for wall-mounting. This cabinet provides added protection against dust and minor impacts. The SPS 4001B consists of a manifold and a calibration gas flowmeter. The manifold provides electrical feedthroughs and calibration gas ports to route power and signal connections and calibration gases to and from the sequencer. In addition, the manifold houses two calibration gas solenoids that sequence the gases to the Oxymitter 5000, a pressure switch that detects low calibration gas pressure, and two PC boards. A terminal strip housed within the terminal cover provides convenient access for all user connections.

Components optional to the SPS 4001B include a reference air flowmeter and pressure regulator. The reference air flowmeter indicates the flow rate of reference air continuously flowing to the Oxymitter 5000. The reference air pressure regulator ensures the instrument air (reference air) flowing to the Oxymitter 5000 is at a constant pressure [20 psi (138 kPa)]. The regulator also has a filter to remove particulates in the reference air and a drain valve to bleed the moisture that collects in the filter bowl.

Operation

PROBE OPTIONS Diffusion Elements

Brass fittings and Teflon tubing are standard. Stainless steel fittings and tubing are optional. Also, disposable calibration gas bottles are available as an option or can be purchased through a local supplier.

The SPS 4001B works in conjunction with the Oxymitter 5000's CALIBRATION RECOMMENDED feature to perform an autocalibration. This feature automatically performs a gasless calibration check every hour on the Oxymitter 5000. If a calibration is recommended and its contact output signal is set for "handshaking" with the sequencer, the Oxymitter 5000 sends a signal to the sequencer. The sequencer automatically performs a calibration upon receiving the signal. Thus, no human interface is required for the automatic calibration to take place.

For further SPS 4001B information, refer to the SPS 4001B Single Probe Autocalibration Sequencer Instruction Manual.

Flame Arrestor Ceramic Diffusion Assembly

The ceramic diffusion assembly, Figure 1-8, includes a set of baffles between the cell and the stack gases. This keeps 816°C (150 0°F) cell temperatures from igniting unburned fuel in the stack. The ceramic diffusion assembly is also available with a dust seal for use with the abrasive shield assembly.

The snubber diffusion assembly, Figure 1-9, is satisfactory for most applications. This element is also available with a dust seal for use with an abrasive shield.

The abrasive shield assembly, Figure 1-10, is a stainless-steel tube that surrounds the probe assembly. The shield protects against particle abrasion and condensations, provides a guide for ease of insertion, and acts as a position support, especially for longer probes. The abrasive shield assembly uses a modified diffuser and vee deflector assembly, fitted with dual dust seal packing.

MECHANICAL INSTALLATION

Instruction Manual

IM-106-350C, Rev 2.2

July 2008

Selecting Location

1. The location of the Hazardous Area Oxymitter 5000 in the stack or flue is most important for maximum accuracy in the oxygen analyzing process. The Hazardous Area Oxymitter 5000 must be positioned so the gas it measures is representative of the process. Best results are normally obtained if the Hazardous Area Oxymitter 5000 is positioned near the center of the duct (40 to 60% insertion). Longer ducts may require several Hazardous Area Oxymitter 5000 units since the O2 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. The sensing point should be selected so the process gas temperature falls within a range of 0° to 704°C (32° to 1300°F). Figure 2-1 through Figure 2-5 provide mechanical installation references.

The ambient temperature of the electronics housing must not exceed 70°C (150°F). For higher ambient temperatures, we r ecommend the remote mounted electronics option.

NOTE

At temperatures up to 85°C (185°F) inside the housi ng, the infrared keypad will cease to function, but the transmitter will continue to operate properly.

2. Check the flue or stack for holes and air leakage. The presence of this condition will substantially affect the accuracy of the oxygen reading. Therefore, either make the necessary repairs or install the Hazardous Area Oxymitter 5000 upstream of any leakage.

3. Ensure the area is clear of internal and external obstructions that will interfere with probe installation and access to the membrane keypad or LOI. Allow adequate clearance for removal of the Hazardous Area Oxymitter 5000 (Figure 2-1 or Figure 2-3).

Probe Installation

2-2

Do not allow the temperature of the Hazardous Area Oxymitter 5000 electronics to exceed 85°C (185°F) or damage to the unit may result.

1. Ensure all components are available to install the Hazardous Area Oxymitter 5000. If equipped with a ceramic diffuser, make sure the diffuser is not damaged.

2. The Hazardous Area Oxymitter 5000 probe may be installed intact, as it is received.

NOTE

An abrasive shield is recommended for high velocity particulates in the flu stream (such as those in coal-fired boilers, kilns, and recovery boilers).

3. Weld or bolt mounting plate (Figure 2-5) onto the duct.

4. If using the optional ceramic diffusion element, the vee deflector must be correctly oriented. Before inserting the Hazardous Area Oxymitter 5000, check the direction of flow of the gas in the duct. Orient the vee deflector so the apex points upstream toward the flow (Figure 2-6). This may be done by loosening the setscrews and rotating the vee deflector to the desired position. Retighten the setscrews.

5. In vertical installations, ensure the system cable drops vertically from the Hazardous Area Oxymitter 5000 and the conduit is routed below the level of the electronics housing. This drip loop minimizes the possibility that moisture will damage the electronics (Figure 2-7).

6. If the system has an abrasive shield, check the dust seal gaskets. The joints in the two gaskets must be staggered 180 degrees. Make sure the gaskets are in the hub grooves as the Hazardous Area Oxymitter 5000 slides into the 15 degree forcing cone in the abrasive shield.

NOTE

If process temperatures will exceed 200°C (392°F), use anti-seize compound on the stud threads to ease future removal of the Hazardous Area Oxymitter

5000.

Instruction Manual

IM-106-350C, Rev 2.2

7. Insert probe through the opening in the mounting plate and bolt the unit to the plate.

NOTE

To maintain CE compliance, ensure a good connection exists between the mounting plate studs or earthing screws on electronics housing and earth.

8. Ensure the Hazardous Area Oxymitter 5000 is properly earthed by way of both internal and external points.

Uninsulated stacks or ducts may cause ambient temperatures around the electronics to exceed 85°C (185°F), which may cause overheating da mage to the electronics

9. If duct work insulation is removed for Hazardous Area Oxymitter 5000 probe mounting, make sure the insulation is replaced afterward. See Figure 2-7.

NOTE

For probe temperatures that will exceed 85°C (185°F ), we recommend the remote mounted electronics option.

Remote Electronics Installation

Figure 2-8. Remote Electronics Mounting

ELECTRICAL INSTALLATION WITH INTEGRAL ELECTRONICS

For a Hazardous Area Oxymitter 5000 with the remote electronics option, install the probe according to the instructions in “Probe Installation” on page 2-2. Install the remote electronics unit on a wall, stand pipe, or similar structure (Figure 2-2 and Figure 2-8).

All wiring must conform to local and national codes.

Disconnect and lock out power before connecting the unit to the power supply.

Install all protective equipment 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 10 A) 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.

The probe and probe abrasive shield are heavy. Use proper lifting and carrying procedures to avoid personnel injury.

To maintain explosion-proof protection, all cable entry devices and blanking elements for unused apertures must be certified flameproof, suitable for the conditions of use and be properly installed.

NOTE

To maintain CE compliance, ensure a good connection exists between the mounting flange bolts and earth.

Connect Line Voltage

1. Remove screw (18, Figure 9-3), cover lock (19), and captive washer (20). Remove cover (17) from terminal block (15).

2. Connect the line, or L1, wire to the L1 terminal and the neutral, or L2 wire, to the N terminal. See Figure 2-9. The Hazardous Area Oxymitter 5000 automatically will configure itself for 90-250 VAC line voltage and 50/60 Hz. To avoid a shock hazard, the power terminal cover must be installed.

3. Connect fieldbus Digital Signal and Logic I/O Calibration Handshake Leads. Use individual shielded twisted wire pairs. Terminate the shield only at the electronics housing.

a. Fieldbus Digital Signal. The fieldbus digital signal carries the O2

value. This digital signal can also be used to communicate with the Oxymitter.

If using an IMPS 4000 or an SPS 4001B, install it in a non-hazardous, explosive-free environment.

b. Calibration Handshake/Logic I/O. The output signal can be used to

trigger an alarm or to provide a calibration handshake signal to an IMPS or SPS 4001B.

c. If autocalibration is not utilized, a common bi-directional logic contact

is provided for any of the equipment alarms listed in Table 8-1. The assignment of alarms that will actuate this contact is modified by one of seven additional configuration settings (mode 1 through mode 7) listed in Table 4-1.

The logic contact is self-powered, +5 VDC, with a 340 ohm series resistance. An interposing relay is required if the logic contact will annunciate a higher voltage device, such as a light or horn. An interposing relay may also be required for certain DCS input cards. A Potter & Brumfield model R10S-E1Y1-J1.0K 3.2 mA DC (or equal) interposing relay will be mounted where the contact wires terminate in the control/relay room.

4. Install cover (17, Figure 9-3) and secure with captive washer (20), cover lock (19), and screw (18).

Hazardous Area Oxymitter 5000 Configuration

3-2

Remove power before changing defaults. If defaults are changed under power, damage to the electronics package may occur.

Located on the microprocessor board, the top board, is a switch that controls the simulate enable status of the Oxymitter 5000 (Figure 3-2). To allow the Oxymitter to be placed in simulation mode, place position two of SW2 in the ON position. Once the Oxymitter has been set to simulate mode, switch position two of SW2 to the OFF position to remove the Oxymitter from simulate mode. Note that SW2 does not actually place the Oxymitter in simulate mode, it only allows the Oxymitter to be placed into simulate mode through the fieldbus interface.

Positions 1, 3 and 4 of SW2 are not used, and should remain in the OFF position.

Typically, the probe's sensing cell, in direct contact with the process gases, is heated to approximately 1357°F (736°C). The external temperat ure of the probe body may exceed 842°F (450°C). If operating conditions also contain high oxygen levels and combustible gases, the Oxymitter 5000 may self-ignite.

Instruction Manual

IM-106-350C, Rev 2.2 July 2008

Hazardous Area Oxymitter 5000

Read O2 Concentration

The O2 range of the Oxymitter is set through the fieldbus interface using the A1 function block.

Refer to Appendix D for more information on using the A1 function block. Once the cell is up to operating temperature, the O2 percentage can be read.

1. Access TP5 and TP6 next to the membrane keypad. Attach a multimeter across TP5 and TP6. The calibration and process gases can now be monitored. Pressing the INC or DEC once will cause the output to switch from the process gas to the calibration gas. Pressing INC or DEC a second time will increase or decrease the calibration gas parameter. If the keys have been inactive for one minute, the output reverts to the process gas. When a calibration has been initiated, the value at TP5 and TP6 is the % O2 seen by the cell. Oxygen levels, as

seen on the multimeter, are:

8.0% O2 = 8.0 VDC

0.4% O2 = 0.4 VDC

NOTE

The maximum reading available at TP5 and TP6 is 30 VDC. While the Oxymitter will measure concentrations up to 40% the test point output will reach a maximum of 30 VDC at a 30% oxygen concentration.

LOGIC I/O

This two-terminal logic contact can be configured either as a solid-state relay-activated alarm or as a bi-directional calibration handshake signal to an IMPS 4000 or SPS 4001B. The configuration of this signal depends on the setting of the LOGIC I/O PIN MODE via fieldbus or LOI. The ten different modes available are explained in Table 3-1.

Alarm

When configured as an alarm, this signal alerts you to an out-of-spec condition. The output is +5 Vdc in series with a 340 ohm resistor.

3-4

Instruction Manual

IM-106-350C, Rev 2.2 July 2008

Table 3-1. Logic I/O Configuration

Hazardous Area Oxymitter 5000

For optimum performance, Emerson Process Management recommends connecting the output to a Potter & Brumfield 3.2 mA DC relay (P/N R10S-E1Y1-J1.0K).

Of the ten modes in Table 3-1, modes 0 through 7 are the alarm modes. The factory default is mode 5 for Hazardous Area Oxymitter 5000 units without an IMPS 4000 or SPS 4001B. In this mode, the output will signal when a unit alarm or a CALIBRATION RECOMMENDED indication occurs.

Calibration Handshake Signal

If using an optional IMPS 4000 or SPS 4001B, the logic I/O must be configured for calibration handshaking. Of the ten modes in Table 3-1 only modes 8 and 9 are configured for calibration handshaking. For a Hazardous Area Oxymitter 5000 with an IMPS 4000 or an SPS 4001B, the factory sets the default to mode 8. In this mode, the logic I/O will be used to communicate between the Hazardous Area Oxymitter 5000 and the sequencer and to signal the sequencer when a CALIBRATION RECOMMENDED indication occurs.

Mode Configuration

0 The unit is not configured for any alarm condition. 1 The unit is configured for a Unit Alarm. 2 The unit is configured for Low O2. 3 The unit is configured for both a Unit Alarm and Low O2. 4 The unit is configured for a High AC Impedance/CALIBRATION

RECOMMENDED.

5* The unit is configured for both a Unit Alarm and a High AC

Impedance/CALIBRATION RECOMMENDED.

6 The unit is configured for both a Low O2 and High AC Impedance/CALIBRATION

Recommended Configuration

Fieldbus Signal Upon Critical Alarm

Emerson Process Management recommends that the factory default be utilized. When a critical alarm occurs which causes the O2 reading to become unstable or unreliable, the Oxymitter will flag the O2 reading. All further O readings will be flagged as Out Of Service until the problem has been corrected.

If the O2 measurement is being utilized as part of an automatic control loop, the loop should be placed into manual upon this failure event or other appropriate action should be taken.

Calibration

Emerson Process Management recommends utilizing an autocalibration system, actuated by the "calibration recommended" diagnostic. New O2 cells may operate for more than a year, but older cells may require recalibration every few weeks as they near the end of their life. This strategy ensures that the O2 reading is always accurate, and eliminates many unnecessary calibrations based on calendar days or weeks since previous calibration. When utilizing the SPS 4001B or IMPS 4000, consider wiring some or all associated alarm contacts.

1. CALIBRATION INITIATE. Contact from the control room to an SPS 4001B or IMPS 4000 (one per probe) provides the ability to manually initiate a calibration at any time from the control room. Note that calibrations can also be initiated via Foundation fieldbus or from the keypad on the Hazardous Area Oxymitter 5000.

2. IN CALIBRATION. One contact per probe provides notification to the control room that the "calibration recommended" diagnostic has initiated an automatic calibration through the SPS 4001B or IMPS 4000. If the O2 signal is being utilized in an automatic control loop, this contact should be utilized to place the control loop into manual during calibration.

3. CALIBRATION FAILED. One contact per probe from an SPS 4001B or IMPS 4000 to the control room for notification that the calibration procedure failed. Grouped with this alarm is an output from a pressure switch which indicates when the calibration gas bottles are empty.

Hazardous Area Oxymitter 5000 Configuration

Remove power before changing defaults. If defaults are changed under power, damage to the electronics package may occur.

Located on the microprocessor board, the top board, is a switch that controls the simulate enable status of the Oxymitter 5000 (Figure 4-2). To access this switch, the LOI module must be removed. To allow the Oxymitter to be placed in simulation mode, place position two of SW2 in the ON position. Once the Oxymitter has been set to simulate mode, switch position two of SW2 to the OFF position to remove the Oxymitter from simulate mode. Note that SW2 does not actually place the Oxymitter in simulate mode, it only allows the Oxymitter to be placed into simulate mode through the fieldbus interface.

Positions 1, 3 and 4 of SW2 are not used, and should remain in the OFF position.

Read O2 Concentration

The O2 range of the Oxymitter is set through the fieldbus interface using the A1 function block.

Refer to Appendix D for more information on using the A1 function block. Once the cell is up to operating temperature, the O2 percentage can be read:

1. To access TP5 and TP6 under the LOI module (Figure 4-2), power down the Oxymitter 5000 and remove the LOI module. Attach alligator leads from a multimeter across TP5 and TP6. Install the LOI module and power up the Oxymitter 5000. Allow time for the cell to reach operating temperature. The calibration and process gases can now be monitored. When a calibration has been initiated, the value at TP5 and TP6 is the % O2 seen by the cell. Oxygen levels, as seen on the multimeter, are:

8.0% O2 = 8.0 VDC

0.4% O2 = 0.4 VDC

NOTE

The maximum reading available at TP5 and TP6 is 30 VDC. While the Oxymitter will measure concentrations up to 40% the test point output will reach a maximum of 30 VDC at a 30% oxygen concentration.

LOGIC I/O

This two-terminal logic contact can be configured either as a solid-state relay-activated alarm or as a bi-directional calibration handshake signal to an IMPS 4000 or SPS 4001B. The configuration of this signal depends on the setting of the LOGIC I/O PIN MODE via FOUNDATION fieldbus or LOI. The ten different modes available are explained in Table 4-1.

Alarm

When configured as an alarm, this signal alerts you to an out-of-spec condition. The output is +5 Vdc in series with a 340 ohm resistor.

4-4

For optimum performance, Emerson Process Management recommends connecting the output to a Potter & Brumfield 3.2 mA DC relay (P/N R10S-E1Y1-J1.0K).

IM-106-350C, Rev 2.2 July 2008

Table 4-1. Logic I/O Configuration

Hazardous Area Oxymitter 5000

Of the ten modes in Table 4-1, mode 1 through mode 7 are the alarm modes. The factory default is mode 5 for Hazardous Area Oxymitter 5000 units without an IMPS 4000 or SPS 4001B. In this mode, the output will signal when a unit alarm or a CALIBRATION RECOMMENDED indication occurs.

Calibration Handshake Signal

If using an optional IMPS 4000 or SPS 4001B, the logic I/O must be configured for calibration handshaking. Of the ten modes in Table 4-1, only modes 8 and 9 are configured for calibration handshaking. For a Hazardous Area Oxymitter 5000 with an IMPS 4000 or an SPS 4001B, the factory sets the default to mode 8. In this mode, the logic I/O will be used to communicate between the Hazardous Area Oxymitter 5000 and the sequencer and to signal the sequencer when a CALIBRATION RECOMMENDED indication occurs.

POWER UP

Startup Display

When power is applied to the probe, the cell heater turns on. It takes approximately one half hour for the cell to heat to operating temperature. This condition is indicated by the top four LEDs (DIAGNOSTIC ALARMS) on the membrane keypad (Figure 5-1). Starting with the CALIBRATION LED, the LEDs light in ascending order until all four LEDs are on. At this point, all four turn off and the cycle starts again. This ramp cycle continues until the cell is up to operating temperature.

Operating Display

The ramp cycle turns into a cycle where the diagnostic LEDs light in sequence from the top to the bottom, one at a time. After the bottom LED turns on, the sequence starts again at the top with the HEATER T/C LED (Figure 5-1).

NAVIGATING THE LOCAL OPERATOR INTERFACE

Overview

Lockout

Refer to Section 9: Maintenance and Service, for calibration instructions.

The Local Operator Interface (LOI), shown in Figure 6-3, utilizes a bright blue gas-fluorescent display. Intensity is adjustable. There is an Infrared LED source and a detector for each key. The detectors can detect a finger placed above the button through the glass window. There is no need to open the instrument in bad weather or in hazardous areas in order to access the electronics.

The Local Operator Interface (LOI) has a lockout feature that prevents nuisance actuation by someone brushing against the glass window, raindrops, dirt, insects, etc. This lockout mode is automatically established when no buttons are pushed for 30 seconds (default). This countdown to lockout is configurable.

6-3

Hazardous Area Oxymitter 5000

In order to unlock the display, input a "Z" pattern. First, push the top left (gray) arrow, then the top right, followed by the bottom left and finally the bottom right. The "LK" notation in the upper right corner of the display will now disappear. Push the gray arrow at the top left hand corner once more to enter into the menu structure. Once one moves deeper into the menu structure, additional time is provided to the user so that the lockout initiation does not become a nuisance. This additional "revert" time is defaulted at one hour and is also user configurable.

NOTE

Always clean dust and soil away from the LOI screen each time the LOI is used. Excessive dust can prevent the LOI from entering lockout. This condition can cause uncommanded operations to occur.

LOI KEY DESIGNATIONS

LOI MENU TREE

The gray key (top left) will move one level higher in the menu structure. When entering numbers, this key will move the cursor to the left. This key also doubles as an "Enter" key, once numbers are entered, and when the cursor is moved to its left-most position. The new data entry value will appear in the top line of the LOI display once it is accepted.

The blue key (bottom left) acts as a selector when choosing from among a number of menu items. This key also will move the cursor to the right when entering numbers.

Up/Down keys (to the left side of the keypad) are used to increment up and down when selecting from a series of menu picks. They are also used for incrementing values up and down for data input.

This LOI menu for the Oxymitter 5000 is shown in Figure 6-4. This menu tree is specific to the Oxymitter 5000. The menu tree will assist in navigating the LOI.

Menu items in normal text display information only. Menu Items in italics permit data entry. Menu items in bold text are procedures.

HAZARDOUS AREA OXYMITTER 5000 SETUP AT THE LOI

In setting up the Hazardous Area Oxymitter 5000 from the LOI, it is best to start at the SYSTEM/Calibration Setup menu, Figure 6-4.

SYSTEM/Calibration Setup O2 Gas #1 - Enter the high or low cal gas value (the order is not important). O2 Gas #2 - Enter the second cal gas value.

NOTE

Refer to Section 9: Maintenance and Service, for calibration instructions.

6-6

Instruction Manual

IM-106-350C, Rev 2.2 July 2008

Hazardous Area Oxymitter 5000

NOTE

Emerson Process Management recommends 0.4% O2 and 8% O2 for calibration gases.

O2 Reset Values - Resets factory default values. O2 Output Tracks - 4 to 20 mA signal can be held at the last value during

calibration, or the signal can be left to track the cal gases. O2 Cal Interval - If automatic calibration is selected, this selects the interval

between calibrations. O2 Next Cal - If automatic calibration is selected, this selects the time until

the first initial calibration takes place. Gas Time - How long should each cal gas flow. Factory default is 300

seconds, but the user may want to vary this depending on the length of calibration gas tubing runs.

Purge Time - Used if the O2 output is selected to hold the last value during calibration. After the second cal gas is removed, how long until the sensor comes back to the normal process reading, and the 4-20 mA signal can be released.

Auto Calib? - Select "Yes" if an SPS or IMPS autocalibration system is part of the system.

SYSTEM/Input/Output Analog

Pertaining to the analog 4-20 mA signal representing O2.

O2 Type - 4-20 mA signal may be configured to increase with increasing O2 or the reverse.

O2 Range - Upper O2 range is user selectable. O2 Alarm Level - User can configure the digital output to alarm at a given

O2 level. Do O2 Trim - Procedure for calibrating the 4-20 mA signal to a precision

mA source. Procedure is intuitive.

Digital

A bi-directional logic signal may be configured as an alarm, or as a calibration handshake signal.

Logic I/O Mode - One of 9 different sets of conditions can be set for the digital signal (Table 8-2).

Low O2 Alarm - If any of the conditions noted above include a low O2 process alarm, set the value here.

Input State - Notes the current condition of the bi-directional digital signal. Force Output - Forces the output state of the signal to either open or

closed. This is used primarily when diagnosing potential problems with this signal.

6-7

Hazardous Area Oxymitter 5000

SYSTEM/Parameters O2 Slope - O2 slope is data regarding the strength of the sensing cell output.

This information is automatically calculated after a calibration, and the user does not normally input this data.

O2 Constant - O2 constant is the amount of voltage a cell generates with ambient air as the calibration gas. Again, this is normally calculated as a result of calibration and is not normally input by the user.

O2 T90 Time - Some users may feel that the O2 reading is too active for certain processes. This feature permits the user to dampen the O2 signal. The default value is zero seconds dampening.

Auto Tune - The electronics detects the line voltage powering the instrument automatically and picks proper algorithms for heater control. User can force a high voltage algorithm, or a low, but Auto Tune is the default, and is recommended.

Lockout Time - Keypad lockout time default is 30 sec. but it is user configurable. A "Z" keypad pattern will unlock the keypad.

Revert Time - Once a user goes one level deep into the menu structure, an additional "revert time" is provided to prevent nuisance lockouts. One hour is the default and it is user configurable.

OVERVIEW

FIELDBUS TERMINAL BLOCK CONNECTIONS

The Model 375 Handheld Communicator is a communications interface device. It provides a common communications link to all microprocessorbased instruments. The handheld communicator contains an 8 x 21 character liquid crystal display (LCD) and 25 keys. A pocket-sized manual, included with the communicator, details the specific functions of all the keys.

To interface with the Oxymitter 5000 the communicator requires a termination point along a common terminal block with the Oxymitter 5000. The Handheld Communicator accomplishes this task by using a fieldbus digital signal to network the components.

The Handheld Communicator may be interfaced with a personal computer (PC), providing that special software has been installed. To connect the Handheld Communicator to a PC an interface adapter is required.

Refer to the proper Handheld Communicator documentation in regard to the PC interface option.

Any device implemented into the system is routed through the fieldbus terminal block. The Handheld Communicator uses the supplied lead set to connect to the terminal block, while the Oxymitter 5000 uses the wires connected to the probe as shown in Figure 7-1. To interface the Handheld Communicator with a personal computer load the designated AMS software into the PC. Then connect the PC to the terminal block as shown in Figure 7-1.

Refer to the proper Handheld Communicator documentation in regard to the PC interface option.

OVERVIEW

While the Hazardous Area Oxymitter 5000 electronics provides a significant number of diagnostic alarms to assist in troubleshooting potential problems, it is good to place these alarms in perspective with respect to the instrument's operating principles:

When the Zirconium Oxide sensing cell is heated to its setpoint [736°C (1357°F)], the cell will generate a voltage that re presents the difference between the process O2% and the reference O2% inside the probe (20.95% O2 ambient air).

Test points, Figure 8-1, are provided to read the raw millivolt value generated by the thermocouple that controls both the cell temperature and the raw cell signal.

The cell temperature at test points 3 and 4 should always be stable at approximately 29 to 30 millivolts, which represents the 736°C setpoint temperature.

When flowing calibration gasses, the raw cell millivolt value at test points 1 and 2 should represent the levels on the chart in Figure 8-1. Note that the raw cell millivolt value increases logarithmically as the O2 concentration decreases.

Hazardous Area Oxymitter 5000

Install all protective equipment covers and safety ground leads after troubleshooting. Failure to install covers and ground leads could result in serious injury or death.

GENERAL

The troubleshooting section describes how to identify and isolate faults that may develop in the Hazardous Area Oxymitter 5000. When troubleshooting, reference the following.

Grounding

It is essential that adequate grounding precautions are taken when installing the system. Thoroughly check both the probe and electronics to ensure the grounding quality has not degraded during fault finding. The system provides facilities for 100% effective grounding and the total elimination of ground loops.

Electrical Noise

The Hazardous Area Oxymitter 5000 has been designed to operate in the type of environment normally found in a boiler room or control room. Noise suppression circuits are employed on all field terminations and main inputs. When fault finding, evaluate the electrical noise being generated in the immediate circuitry of a faulty system. Ensure all cable shields are connected to earth.

Loose Integrated Circuits

The Hazardous Area Oxymitter 5000 uses a microprocessor and supporting integrated circuits (IC). If the electronics are handled roughly during installation or located where subjected to severe vibration, the ICs could work loose. Before troubleshooting the system, ensure all ICs are fully seated.

Electrostatic Discharge

Electrostatic discharge can damage the ICs used in the electronics. Before removing or handling the processor board or the ICs, ensure you are at ground potential.

ALARM INDICATIONS

The majority of the fault conditions for the Hazardous Area Oxymitter 5000 will be indicated by one of the four LEDs referred to as diagnostic, or unit alarms on the operator's keypad (Figure 8-2). An LED will flash a code that will correspond to an error message. Only one LED will blink at a time. An alarm code guide is provided inside the screw-on cover for the electronics.

Alarm indications will be also available via the optional LOI or the fieldbus computer terminal. When the error is corrected and/or power is cycled, the diagnostic alarms will clear or the next error on the priority list will appear.

ALARM CONTACTS

If autocalibration is not utilized, a common bi-directional logic contact is provided for any of the diagnostic alarms listed in Table 8-1. The assignment of alarms which can actuate this contact can be modified to one of seven additional groupings (mode 0 through mode 7) listed in Table 3-1.

The logic contact is self-powered, +5 VDC, with a 340 ohm series resistance. An interposing relay will be required if this contact is to be utilized to annunciate a higher voltage device, such as a light or horn. An interposing relay may also be required for certain DCS input cards.

A Potter & Brumfield R10S-E1Y1-J1.0K 3.2 mA DC or an equal interposing relay will be mounted where the contact wires terminate in the control/relay room.

If autocalibration systems are utilized, the bi-directional logic contact is utilized as a "hand-shake" signal between the autocalibration system (SPS 4001B or IMPS 4000) and is unavailable for alarming purposes. The following additional contacts are provided through the autocalibration systems:

Instruction Manual

IM-106-350C, Rev 2.2 July 2008

Hazardous Area Oxymitter 5000

SPS 4001B and IMPS 4000, 1-4 probes

• One contact closure per probe from the control room to the SPS 4001B or IMPS 4000 for "calibration initiate".

• One contact output per probe from the SPS 4001B or IMPS 4000 to the control room for "in calibration" notification.

• One contact output per probe from the SPS 4001B or IMPS 4000 to the control room for "calibration failed" notification. (Includes output from pressure switch indicating "cal gas bottles empty").

Additional IMPS 4000 Alarm Contacts

• One contact per IMPS 4000 for "low calibration gas flowing".

• One contact per IMPS 4000 for "high calibration gas flowing".

IDENTIFYING AND CORRECTING ALARM INDICATIONS

For a Hazardous Area Oxymitter 5000 with a membrane keypad, faults are indicated by four diagnostic, or unit, alarm LEDs. A pattern of repeating blinks define the problem. A condensed table of the errors and the corresponding blink codes can be found on the inside right cover of the electronics housing. Table 8-1 also identifies the blink code and fault status of each LED.

For a Hazardous Area Oxymitter 5000 with the optional LOI, alarm messages are displayed on the LOI display window when the alarm status display is accessed via the LOI menu. A listing of the alarm/fault messages and the related fault status descriptions and fault numbers are shown in Table 8-2.

flashes three times, pauses for three seconds, and repeats.

1. If the case temperature exceeds 85°C (185°F), the temperature control will shut off and a fieldbus alarm will be sent.

2. This signifies that the environment where the Hazardous Area Oxymitter 5000 is installed exceeds the ambient temperature requirements or that heat due to convection is causing case temperature to rise above the limit.

3. Placing a spool piece between the stack flange and the Hazardous Area Oxymitter 5000 flange may eliminate this problem.

4. If a spool piece does not solve the problem, relocation is the only solution.

LOI

When Fault 7 is detected, the LOI displays the "Board Temp Hi" message. Refer to the comments in paragraphs 1 through 4 above.

Fault 10, High Cell mV

Figure 8-12 shows the electronic assembly for a Hazardous Area Oxymitter 5000 with a membrane keypad (upper view) and a Hazardous Area Oxymitter 5000 with an LOI (lower view). The upper view also shows J1 and test points TP1 through TP6, located on the microprocessor board, below the membrane keypad or the LOI module.

Membrane Keypad

When Fault 10 is detected, the O2 CELL flashes once, pauses for three seconds, and repeats.

1. Using a multimeter, measure across TP1+ to TP2-. If you measure 204 mV to 1 volt DC, the cell reading is due to high combustibles. This is a self-clearing alarm, once the combustible conditions go away. If you measure 1.2 VDC, the cell wires, either orange or green, have become detached from the input.

2. One possible cause is connector J1. The orange or green wire has come loose from the crimped connection.

3. The platinum pad could also be at fault. The pad could have broken free from the back of the cell.

4. Replace heater strut per "Heater Strut Replacement" in Section 9: Maintenance and Service. If necessary, replace the cell and flange assembly per "Cell Replacement" in Section 9: Maintenance and Service.

8-16

LOI

When Fault 10 is detected, the LOI displays the "O2 Cell Open" message.

1. Remove power. Unscrew and remove the LOI module from the electronic assembly.

2. Reconnect power to the Oxymitter 5000.

3. Perform the diagnostic steps 1 through 4 shown for the membrane keypad.
