Introduction 1-3

1-2. Application

The EXA transmitter is intended to be used for continuous on-line measurement in industrial installations. The unit combines simple operation and microprocessor-based performance with advanced self-diagnostics and enhanced communications capability to meet the most advanced requirements. The measurement can be used as part of an automated process control system. It can also be used to indicate dangerous limits of a process, to monitor product quality, or to function as a simple controller for a BOD/COD system.

Yokogawa designed the EXA analyzer to withstand harsh environments. The transmitter may be installed either indoors or outside because the IP65 (NEMA 4X) housing and cabling glands ensure the unit is adequately protected. The flexible polycarbonate window on the front door of the EXA allows pushbutton access to the keypad, thus preserving the water and dust protection of the unit even during routine maintenance operations.

A variety of EXA hardware is optionally available to allow wall, pipe, or panel mounting. Selecting a proper installation site will permit ease of operation. Sensors should normally be mounted close to the transmitter in order to ensure easy calibration and peak performance. If the unit must be mounted remotely from the sensors, WF10 extension cable can be used up to a maximum of box.

The EXA is delivered with a general purpose default setting for programmable items. (Default settings are listed in Chapter 5). While this initial configuration allows easy start-up, the configuration should be adjusted to suit each particular application. An example of an adjustable item is the type of sensor used. The EXA can be adjusted for galvanic and polarographics sensors.

30 metres (100 feet) with a BA10 junction

To record such configuration adjustments, write changes in the space provided in APPENDIX 1 of this manual. Because the EXA is suitable for use as a monitor, a controller or an alarm instrument, program configuration possibilities are numerous.

Details provided in this user’s manual are sufficient to operate the EXA with all Yokogawa sensor systems and a wide range of third-party commercially available probes. For best results, read this manual in conjunction with the corresponding sensor user’s manual.

Yokogawa designed and built the EXA to meet the CE regulatory standards. The unit meets or exceeds stringent requirements of EMC Directive 89/336/EEC, to assure the user of continued accurate performance in even the most demanding industrial installations.

2. GENERAL SPECIFICATIONS

General Specifications 2-1

2-1. Specifications

A. Input specifications

The DO202 accepts output from membrane covered Dissolved Oxygen sensors. These sensors can be Galvanic type, where the sensor generates its own driving voltage or Polarographic type, where the sensor uses external driving voltage from the transmitter. The input range is 0-50 A for Galvanic sensors and 01 A for Polarographic sensors. For temperature compensation the DO202 accepts Pt1000 (DO30 sensor) and 22kNTC elements (OXYFERM and OXYGOLD sensors)

B. Measuring range

- Dissolved Oxygen : 0 - 50 ppm (mg Oxygen

per kg water); 0 - 1999 ppb (mg Oxygen per 1000 kg water) and 0

- 600 % Saturation of Air in Water.

- Temperature : -20 to 150ºC (-4 to 302ºF).

C. Temperature compensation

Automatic using Pt1000 or 22kNTC or manual Range 0 - 100ºC (32 to 212 ºF)

D. Calibration

Semi-automatic one or two point calibration in air or in water using solubility tables of ISO 5814. The influence of pressure and salinity is taken into account when these specifications are entered. Also a two point manual calibration is possible.

E. Transmission Signals

Isolated output of 4-20 mA DC, Burn up (21 mA) or Burn dwon (3.6 mA when HART® comm. nonused, 3.9 mA when HART comm. used) or pulse of 21 mA to signal failure.

Note: The transmitter contains a switched

power supply. The transmitter requires a minimum power voltage in order to work correctly, which is dependant on the load. Please refer to figures 2-1 and 2-2 for the correct power supply

3-2. Wiring of power supply

3-2-1. General precautions

mA

Do not activate the power supply yet. First make sure that the DC-power supply is according to the specifications given.

WARNINGWARNING

DO NOT USE ALTERNATING CURRENT OR MAINS POWER SUPPLY! !

The cable leading to the distributor (power supply) or safety barrier transports power to and output signal from the transmitter. Use a two conductor shielded cable with a size of at least 1.25 mm diameter of 6 to 12 mm. The cable gland supplied with the instrument accepts these diameters. The maximum length of the cable is 2000 metre, or 1500 metres when using the communications. This ensures the minimum operating voltage for the instrument.

Grounding:

• If the transmitter is mounted on a grounded

surface (e.g. a metal frame fixed in the soil) the shield of the 2-wire cable may NOT be connected to ground at the distributor.

• If the transmitter is mounted on a non-conducting

surface (e.g. a brick wall) it is recommended to ground the shield of the 2-wire cable at the distributor end.

mA

3-2-2. Connection of the power supply

The terminal strip is accessed as was described in section 3-2-1. Use the left-hand gland to insert the supply/output cable to the transmitter. Connect the supply to the terminals marked +, - and G as is indicated in figures 3-7.

3-2-3. Switching the instrument on

After all connections are made and checked, the power can be switched on from the distributor. Observe the correct activation of the instrument at the display. If for any reason the display does not indicate a value, consult the trouble shooting section.

3. Remove loose copper screening, and cut off the cotton packing threads as short as possible.

4. Strip insulation from the last 3 cm of the brown, and the white coaxial cores.

3-3-6. Additional precautions for installations in

hazardous areas

Make sure that the total of capacitance and inductances connected to the input terminals of the EXA DO202S do not exceed the limits given in the certificate. This sets a limit to the cable and extensions used. – The intrinsic safe version of the DO202S

instrument can be mounted in Zone 1 (DO202S-B,

-N, -D).

– The sensors can be installed in Zone 0 or Zone 1

if a safety barrier according to the limits given in the system certificate is used.

– Ensure that the total of capacitance and

inductances connected to the terminals of the EXA DO202S do not exceed the limits given in the certificate of the safety barrier or distributor.

– The cable used should preferably have a BLUE

colour or marking on the outside. – Installation for (sensors in Zone 0 or 1): Generally, the distributor with input/output isolation

has no external earth connection. If there is

an earth connection on the distributor and the

external connection of the transmitter is connected

to “protective” earth, the shield of the 2-wire cable

may NOT be connected to “protective” earth at the

distributor too.

6. CALIBRATION PROCEDURE

Calibration Procedure 6-1

Calibration of the dissolved oxygen analyzer is performed in the following situations:

• When a new dissolved oxygen sensor is installed.

• When the membrane is replaced and/or the electrolyte solution is replaced

• When the sensor has been disassembled and reassembled for maintenance

• When the measuring error after cleaning exceeds the acceptable deviation from reference method

• When error message E16 indicates the need for maintenance

6-1. General

6-1-1. Calibration methods

There are four methods for calibration of the EXA dissolved oxygen analyzer: air calibration, water calibration, sensitivity and zero (offset) calibration.

Air calibration

This is the most common and easiest way to calibrate the analyzing system. The calibration is done in AIR.CAL mode in maintenance level.

Water calibration

This is the traditional way to calibrate dissolved oxygen analyzers in laboratory environment. . Accurate results can be obtained if the calibration is performed carefully. The water calibration may include a zero calibration if so selected in service code 21. Normally only a zero check is performed without calibration, since a good sensor has no zero signal. Water calibration is not possible in salt water unless salinity compensation is activated in service code

04. The calibration is done in H2O.CAL mode in

maintenance level

Note: In normal industrial environments better

results are obtained with air calibration, which is therefore the recommended method.

Manual calibration

This is a calibration method whereby the sensor is not exposed to a calibration fluid, but is calibrated by comparison with a reference method. This reference method is normally a laboratory analysis of the water sample: either by Iodometric titration according ISO 5813 or an electrochemical method according ISO 5814. The calibration is done in SENS/ZERO mode in maintenance level.

6-1-2. Diagnostic functions performed during

calibration

The calibration is a semi-automatic calibration, which means that the sensor output is used for calculation of sensor parameters after the readings have stabilized. The criteria for stabilization are set in service code 20. If stable readings are not achieved within one hour error E1 message will appear on the display and the procedure is aborted.

The calculated sensor parameters are compared with preset tolerances and if these conditions are not met, Error E2 (Zero Error) or E3 (Sensitivity Error) will be signalled.

Notes:

1. Error messages that appear initially indicate inadequate settings of the diagnostic variables in service codes 01, 20 and/or 22.

2. Patience improves the accuracy of calibration. When the EXA prompts the user that the preset criteria are met by showing CAL.END message it only means that the minimum criteria are met. When the signal still changes after this initial acceptance, EXA will automatically update the sensor characteristics with the new information.

6-3-1. Preparation

Move the sensor to a maintenance site and wash off any dirt on the membrane. Lightly wipe off any remaining water from the membrane with a soft tissue. Prepare the necessary equipment and reagents to be used for the span and (if required) zero calibration. Equipment for span calibration includes:

• Beaker or bucket

•

Magnetic stirrer or other means of agitating the water

• Demineralized water or salty process water if salinity compensation is activated

• Air supply pump (aquarium pump)

• Glass diffuser to generate small air bubbles

Note: It takes 15 to 30 minutes of aeration before

it can be assumed that the water is fully saturated with air.

Reagent for zero calibration:

• Sodium sulfite

• demineralized water

The zero oxygen solution contains 20- 30 grams of sodium sulfite per liter.

If both zero and span calibration are used, it is better to start with span calibration in spite of normal calibration sequence with analog instrumentation. Otherwise the sensor must be rinsed off carefully to prevent ingress of oxygen absorbing sulfite in the aerated water. Note: Zero calibration in the sodium sulfite solution

takes a long time. Even after CAL.END prompt it is necessary to wait 40-50 minutes before zero adjustment can be made. Otherwise calibration errors are introduced in the measurement. It is recommended not to do a zero calibration, but a zero check only. A good clean sensor does not have a zero current and does not require zero calibration. If the sensor has a substantial zero current, the sensor has to be disassembled, cleaned and filled with fresh electrolyte solution and a new membrane has to be fitted.

Calibration may take longer than 10 minutes.

Before starting the calibration procedure, check the setting of Auto Return (*RET.) in Service Code 50. It is recommended to set the Auto Return to “0” (No return to meas. from HOLD). After the calibration procedure has been completed, set the Auto Return to the desired setting in Service Code 50.

6-4 Calibration Procedure

6-4-1. Preparation

A. Cleaning

Confirm that the readings of the analyzer are stable and measured with a clean sensor.

Otherwise move the sensor to a maintenance site and wash off any dirt on the sensor membrane Move the sensor back to the process water and wait for the readings to stabilize.

B. Sampling

The manual calibration procedure involves adjustment of the readings to a reference standard. Normally this reference is a laboratory measurement that analyses a sample that must be identical to the sample measured with the online analyzer.

6-4-2. Procedure for manual slope (sensitivity) calibration

The following precautions must be taken into account:

• The sample must be analyzed directly after sampling to avoid change of dissolved oxygen concentration or temperature after sampling

• The reference standard must be analyzed with a laboratory meter that is calibrated prior to sample analysis

• The reference method must be calibrated with the same calibration data as specified in ISO 5814 to avoid indiscrepancies

Most important calibration data are: Dissolved oxygen concentration at saturation conditions as function of temperature, barometric pressure, altitude and salinity.

These data are included in this manual for reference and verification of correct calibration of reference analyzers. DO202 has taken all these variables into account during the semi-automatic calibration methods.

(Chapter 9) for replacement part numbers. (NEMA 4X) standards, and remains closed in normal operation. Users are required only to make sure the front window is kept clean in order to permit a clear view of the display and allow proper operation of the pushbuttons. If the window becomes soiled, clean it using a soft damp cloth or soft tissue. To deal with more stubborn stains, a neutral detergent may be used.

When you must open the front cover and/or glands, make sure that the seals are clean and correctly fitted when the unit is reassembled in order to maintain the housing’s weatherproof integrity against water and water vapor. The DO measurement uses small signal currents and may otherwise be prone to problems caused by exposure of the circuitry to condensation.

8. TROUBLESHOOTING

8-1 Troubleshooting

This chapter describes the countermeasures for failures, classifying the cases into three categories: dissolved-oxygen transmitter failure, detection of failure with the self-diagnosis function, and abnormal measured values. The causes for abnormal measured values are not limited to equipment failures. If an abnormal phenomenon occurs, first check the following items:

• Is the property of the measuring solution different

from normal?

8-1. Measures in the case of transmitter opera-

tion failure

If the operation keys do not operate smoothly or the display fails (e.g., a missing character segment), repair of the printed circuit board (digital board) or replacement with a new one is required. After the printed circuit board is replaced, operation checks and parameter settings are necessary. Contact Yokogawa and request board-replacement work.

• Is the dissolved-oxygen sensor properly installed?
