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 selfdiagnostics 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 dosing/neutralization system. Yokogawa designed the EXA transmitter to withstand harsh environments. The transmitter may be installed either indoors or outside because the IP65 and 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 50 mtr (150 feet) with a BA10 junction box. The EXA is delivered with a general purpose default setting for programmable items. (Default settings are listed in Section 5 and again in Chapter 11). 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 temperature sensor used. The EXA can be adjusted for two different types of temperature sensors. To record such configuration adjustments, write changes in the space provided in Chapter 11 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. To assure the user of continued accurate performance in even the most demanding industrial installations.

3-1-1. Installation site

The EXA transmitter is weatherproof and can be installed inside or outside. It should, however, be installed as close as possible to the sensor to avoid long cable runs between sensor and transmitter. In any case, the cable length should not exceed 60 mtr (200 feet). Select an installation site where:

• Mechanical vibrations and shocks are negligible

• No relay/power switches are in the direct environment

• Access is possible to the cable glands (see figure 3-1)

• The transmitter is not mounted in direct sunlight or severe weather conditions When the instrument with Suffix Code "-B,-N,-D" is used, take measures so that the display window is

not exposed to direct sunlight.

• Maintenance procedures are possible (avoiding corrosive environments) The ambient temperature and humidity of the installation environment must be within the limits of the instrument specifications. (See section 2).

3-1-2. Mounting methods

Refer to figures 3-2 and 3-3. Note that the EXA transmitter has universal mounting capabilities:

• Panel mounting using optinal bracket, refer to Fig. 3-2a.

• Panel mounting using two (2) self-tapping screws, refer to Fig. 3-2b.

• Surface mounting on a plate (using bolts from the back).

• Wall mounting on a bracket (for example, on a solid wall).

• Pipe mounting using a bracket on a horizontal or vertical pipe (nominal pipe diameter JIS 50A).

3-3. Wiring of sensors 3-3-1. General precautions

Generally, transmission of signals from Inductive Conductivity sensors is at a low voltage and current level. Thus a lot of care must be taken to avoid interference. Before connecting sensor cables to the transmitter make sure that the following conditions are met:

• the sensor cables are not mounted in tracks together with high voltage and or power switching cables.

• only standard sensor cables or extension cable are used.

• the transmitter is mounted within the distance of the sensor cables (max. 10 m) + up to 50 m WF10 extension cable.

• the setup is kept flexible for easy insertion and retraction of the sensors in the fitting.

3-3-2. Additional precautions for installations in hazardous areas

Make sure that the total of capacitance and inductances connected to the input terminals of the EXA ISC202S 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 ISC202S instrument can be mounted in Zone 0 or 1 (ISC202S-B, -N,

-D).

• The sensor 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 ISC202S 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.

3-3-3. Installation in: Hazardous Area-Non-Incendive

The EXA ISC202S-N may be installed in a Category 3/ Zone 2/ Div.2 area without the use of safety barriers. Maximum permissible supply voltage 31.5V.

3-4-1 General precautions

WARNING

First make sure that the DC-power supply is according the specifications given.

DO NOT USE ALTERNATING CURRENT OR MAINS POWER SUPPLY! !

The cable leading to the distributor (power supply) or safety barrier transports power to an output signal

from the transmitter. Use a two conductor shielded cable with a size of at least 1.25 mm

and an outside diameter of 6 to 12 mm. The cable gland supplied with the instrument accepts these diameters. The maximum length of the cable is 2000 mtr, or 1500 mtr 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.

3-4-2. Connection of the power supply

The terminal strip is accessed as was described in 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 3-8.

3-4-3. 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.

3-5. Sensor wiring

Refer to figure 3-7, which includes drawings that outline sensor wiring.

To connect the sensors, simply match the terminal numbers in the instrument with the identification numbers on the cable ends.

3-6. Other sensor systems

To connect other sensor systems, follow the general pattern of the terminal connections as listed below: 11 and 12 : Always used for temperature compensation resistor input. 13 and 17 : Used for the secondary ‘collector’ coil. 15 and 16 : Used for the primary ‘drive’ coil. 14 : Overall screen

Figure 3-8. Terminal identification label

3-6-1. Sensor cable connections using junction box (BA10) and extension cable (WF10)

Where a convenient installation is not possible using the standard cables between sensors and transmitter, a junction box and extension cable may be used. The Yokogawa BA10 junction box and the WF10 extension cable should be used. These items are manufactured to a very high standard and are necessary to ensure that the specifications of the system are not compromised. The total cable length should not exceed 60 mtr (e.g. 5 m fixed cable and 55 m extension cable).

select for example 0-100 S/cm range.

*HOLD : The EXA ISC202 transmitter has the ability to ‘HOLD’ the output during maintenance

periods. This parameter should be set up to hold the last measured value, or a fixed value to suit the process (Section 5-2-2).

*TEMP.1, 2 :

First/second temperature compensation types and values (see section 5-2-4 and 5-2-5).

* NaCl is used for neutral salt solutions. Strong solutions of salts are compensated, as

are process waters, pure, and ultrapure water.

* T.C. temperature coefficient compensation uses a linear temperature compensation

factor. This can be set by calibration (section 5) or configuration (service code 21).

* MATRX compensation is an extremely effective way of compensation. Choose from

standard matrix tables, or configure your own to exactly suit your process.

5-2-3. Temperature compensation

Why temperature compensation?

The conductivity of a solution is very dependent on temperature. Typically for every 1 °C change in temperature the solution conductivity will change by approximately 2 %. The effect of temperature varies from one solution to another and is determined by several factors like solution composition, concentration and temperature range. A coefficient ( ) is introduced to express the amount of temperature influence in % change in conductivity per °C. In almost all applications this temperature influence must be compensated before the conductivity reading can be interpreted as an accurate measure of concentration or purity.

1 Standard temperature compensation (NaCl)

From the factory the EXA is calibrated with a general temperature compensation function based on a sodium chloride salt solution. This is suitable for many applications and is compatible with the compensation functions of typical laboratory or portable instruments.

Calculation example

Calculate the temperature co-efficient of a liquid from the following data. Conductivity 124.5 S/cm at a liquid temperature of 18.0 °C and a conductivity 147.6 S/cm at a liquid temperature of 31.0 °C.

Substituting the data in the above formula gives the following result.

 =

124.5(31.0 - 25) - 147.6(18.0 - 25)

147.6 - 124.5 x 100% = 1.298%/ ºC

Set the temperature coefficient in the EXA transmitter.

2-C. Checking

When the temperature coefficient already set is accurate, the conductivity to be displayed must be constant regardless of liquid temperature. The following check will make sure that the temperature coefficient already set is accurate. If, when the liquid temperature is lowered, a larger conductivity value is indicated, the temperature coefficient already set is too small. The opposite also applies. If a smaller conductivity value is indicated, the temperature coefficient already set is too large. In either case, change the temperature coefficient so that the conductivity no longer changes.

3. Matrix compensation

The compensation matrix is a table of temperature and conductivity values at differing concentrations. These values are used to calculate the temperature compensation applicable for a particular solution. Choose the component that you will be measuring in your application, and where appropriate the concentration range. EXA will do the rest.

4. Manual temperature compensation (Section 5-2-4 and 5-2-5)

If the standard compensation function is found to be inaccurate for the sample to be measured, the transmitter can be set manually for a linear factor on site to match the application. The procedure is as follows:

1. Take a representative sample of the process liquid to be measured.

2. Heat or cool this sample to the reference temperature of the transmitter (usually 25 °C).

3. Measure the conductivity of the sample with the EXA and note the value.

4. Bring the sample to the typical process temperature (to be measured with the EXA).

5. Adjust the display indication to the noted value at the reference temperature.

6. Check that the temperature compensation factor has been changed.

7. Insert the conductivity cell into the process again.

5. Other possibilities (section 5-3)

1. Enter calculated coefficient.

2. Enter matrix temperature compensation.

Code 11 *T.UNIT Celsius or Fahrenheit temperature scales can be selected to suit user

preference.

Code 12 *T.ADJ With the process temperature sensor at a stable known temperature, the

temperature reading is adjusted in the main display to correspond. The calibration is a zero adjustment to allow for the cable resistance, which will obviously vary with length.The normal method is to immerse the sensor in a vessel with water in it, measure the temperature with an accurate thermometer, and adjust the reading for agreement.

5-3-3. Temperature compensation functions

Code 20 *T.R.°C Choose a temperature to which the measured conductivity (or resistivity) value

must be compensated. Normally 25°C is used, therefore this temperature is chosen as default value. Limitations for this setting are: -20 to 140 °C. If *T.UNIT in code 11 is set to °F, default value is 77°F and the limitations are 0 - 280°F.

Code 21 *T.C.1, 2 In addition to the procedure described in section 5-2-4 and 5-2-5 it is possible

to adjust the compensation factor directly. If the compensation factor of the sample liquid is known from laboratory experiments or has been previously determined, it can be introduced here. Adjust the value between 0.00 to 3.50 % per °C. In combination with reference temperature setting in code 20 a linear compensation function is obtained, suitable for all kinds of chemical solutions.

Code 22 *MATRX The EXA is equipped with a matrix type algorithm for accurate temperature

compensation in various applications. Select the range as close as possible to the actual temperature/concentration range. The EXA will compensate by interpolation and extrapolation. Consequently, there is no need for a 100% coverage. If 9 is selected the temperature compensation range for the adjustable matrix must be configured in code 23. Next the specific conductivity values at the different temperatures must be entered in codes 24 to 28. Matrix data is exeplified in Appendix 11-3

Code 23 *T1, *T2, *T3, Set the matrix compensation range. It is not necessary to enter equal *T4 & *T5 °C temperature steps, but the values should increase from T1 to T5, otherwise

the entrance will be refused. Example: 0, 10, 30, 60 and 100 ºC are valid

values for the T1....T5. The minimum span for the range (T5 - T1) is 25 °C. The

valid range for a temperature value is -20º to 140ºC.

Code 24-28 *L1xT1 - In these access codes the specific conductivity values can be entered for L5xT5 5 different concentrations of the process liquid; each one in one specific access

code (24 to 28). The table below shows a matrix entering example for 0.5 - 5% H2SO4 solution for a temperature range from 0 - 100 °C. Conductivity range from 0.0 S/cm to 1999 mS/cm.

NOTES:

1. In chapter 11 a table is included to record your programmed values. It will make programming easy for duplicate systems or in case of data loss.

2. Each matrix column has to increase in conductivity value.

3. Error code E4 occurs when two standard solutions have identical conductivity values at the same temperature within the temperature range.

5-3-4. mA output functions

Code 31 *OUTP.F For the ISC202 the output may be chosen as linear to input, or configured in

a 21 point table to a particular linearization. Enable the table setup in code 31, and configure the table in code 35.

Code 32 *BURN Diagnostic error messages can signal a problem by sending the output signals

upscale or downscale (21 mA or 3.6 mA when HART or distributor comm. is non-used, 3.9 mA when HART or distributor comm. is used). This is called upscale or downscale burnout, from the analogy with thermocouple failure signaling of a burned-out or open circuit sensor. The pulse burnout setting gives a 21 mA signal for the first 30 seconds of an alarm condition. After the ‘pulse’ the signal returns to normal. This allows a latching alarm unit to record the error. In the case of the EXA the diagnostics are extensive and cover the whole range of possible sensor faults.

Code 35 *TABLE The table function allows the configuration of an output curve by 21 steps

(intervals of 5%). The following example shows how the table may be configured to linearize the output with a mA curve.

Calibration 6-1

6. CALIBRATION

6-1 When is calibration necessary?

Calibration of conductivity instruments is normally not required, since Yokogawa delivers a wide range of sensors, which are factory calibrated traceable to NIST standards. The cell constant values are normally indicated on the top of the sensor or on the integral cable. These values directly can be entered in service code 03 (section 5-3-1). If the cell has been subjected to abrasion (erosion or coating) calibration may be necessary. In the next section two examples are given. Alternatively calibration may be carried out with a simulator to check the electronics only.

NOTE:

During calibration the temperature compensation is still active. This means that the readings are

refered to the reference temperature as chosen in service code 20 (section 5-3-4, default 25 °C).

alibration is normally carried out by measuring a solution with a known conductivity value at

a known temperature. The measured value is adjusted in the calibration mode. On the next pages the handling sequence for this action is visualised. Calibration solutions can be made up in a laboratory. An amount of salt is dissolved in water to give a precise concentration with the temperature stabilised to the adjusted reference temperature of the instrument (default 25 °C). The conductivity of the solution is taken from literature tables or the table on this page.

Alternatively the instrument may be calibrated in an unspecified solution against a standard instrument. Care should be taken to make a measurement at the reference temperature since differences in the type of temperature compensation of the instrument may cause an error.

NOTE:

The standard instrument used as a reference must be accurate and based on an identical

temperature compensation algorithm. Therefore the Model SC72 Personal Conductivity Meter of Yokogawa is recommended.

Typical calibration solutions. The table shows some typical conductivity values for sodium-chloride (NaCl) and Potassium cholide (KCl) solutions which can be made up in a laboratory.

Maintenance 7-1

7. MAINTENANCE

7-1. Periodic maintenance for the EXA 202 transmitter

The EXA transmitter requires very little periodic maintenance. The housing is sealed to IP65 (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.

NOTE:

Never used harsh chemicals or solvents. In the event that the window becomes heavily stained or

scratched, refer to the parts list (Section 10) for replacement part numbers.

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 vapour. The measurement otherwise may be prone to problems caused by exposure of the circuitry to condensation.

The EXA instrument contains a lithium cell to support the clock function when the power is switched off. This cell needs to be replaced at 5 yearly intervals (or when discharged). Contact your nearest Yokogawa service centre for spare parts and instructions.

7-2. Periodic maintenance of the sensor

Maintenance advice listed here is intentionally general in nature. Sensor maintenance is highly application specific.

In general conductivity measurements do not need much periodic maintenance. If the EXA indicates an error in the measurement or in the calibration, some action may be needed (ref. Section 8 troubleshooting).

Cleaning methods

1. For normal applications hot water with domestic washing-up liquid added will be effective.

2. For lime, hydroxides, etc., a 5 ...10% solution of hydrochloric acid is recommended.

3. Organic foulings (oils, fats, etc.) can be easily removed with acetone.

4. For algae bacteria or moulds, use a solution of domestic bleach (hypochlorite).

* Never use hydrochloric acid and bleaching liquid simultaneously. The very poisonous chlorine gas will

result.

Trouble shooting 8-1

8. TROUBLESHOOTING

8-1. Introduction

The EXA ISC202 microprocessor based conductivity analyser continuously monitors the condition of all key components of the measuring system to ensure that measurement is dependable. If a fault is detected this is immediatly signalled. Errors are shown on the display with a code. Table shows the errors which can be detected and gives information to help locate the fault or identify the error. Faults detected while the instrument is on line can also be signalled by a burnout (section 5-5).

8-2. Self diagnostics of the conductivity sensor

During measurement the instrument adjusts the measuring parameters to give the best conditions for the actual value being measured. At all values the instrument checks the signal from the cell to search for distortion. If there is a problem with the installation of the cell and this becomes defective this will trigger an error message on the display possibly accompanied by a by a burnout signal (section 5-5).

8-3. Self diagnostics of the temperature sensor

The temperature sensor, which is normally built into the conductivity cell, is checked to detect damage or faulty connections.

8-4. Self diagnostics of the electronics

The microprosessor opertion is checked by a watchdog which initiates an electronic reset if the normal functions suffers severe interference. During reset the instrument checks the program and all stored data. If a fault is then detected an alarm is given.

8-5. Checking during operation

Whenever the instrument is being programmed or calibrated, data is checked and an error is shown when appropriate. Should this occur the new data is rejected and the instrument continues to work with the previuos settings.

Communication setup with PH201G (style B) distributor (service code 60) This communication is a one-way to PH201G (Style B) distributor, a power supplier for the EXA 202 transmitters. The PH201G (Style B) receives a current signal (4-20 mA DC) and a digital signal superimposed on the DC signal. In other words, the PH201G (Style B) provides a measurement signal, a holdcontact signal and a fail-contact signal. The communication with PH201G (Style B) is set in Service code

60.

Code 60 *COM The settings should be adjusted to suit the communicating device connected to the out-

put. The communication can be set to HART® or to PH201G (Style B) distributor. When used with our PH201G (Style B) you can enable or disable contact outputs, namely, Fail contact and Hold contact. The PH201G (Style B) can output Hold contact and Fail contact signals. You can set Service Code 53 to “0” for “soft fail” to disable Fail contact output. When you set Service Code 53 to “1” for “hard fail”, set Service Code 60 to “2.0” to enable Fail contact output of PH201G (Style B), or set Service Code 60 to “0.1” to disable Fail contact output of PH201G (Style B).

12-4-1. Settings Performed in Maintenance Mode

12-4-1-1 Calibration with solution of known conductivity

Refer to Sec. 6 for Calibration

1. When is calibration required?

Inductive conductivity meters should be calibrated before they are first used, but should not need periodic calibration after that: the ISC202/ISC40 inductive conductivity measuring system passes a current through the measured liquid to measure its conductivity; if there is little clearance (less than 30 mm) around the sensor then this can affect the accuracy of calibration, and the sensor should be calibrated before use. Also if the sensor surface becomes corroded or contaminated, you should recalibrate it.

2. How is calibration performed

Calibration normally involves measuring a liquid of known conductivity at a known temperature, and adjusting the meter to read the correct value. Since the reading is affected by the mounting, the sensor should be calibrated on site after installation. You can mix standard solutions of KCl or NaCl for calibration. The temperature of the standard solution should be maintained at the reference temperature. Conductivity tables for NaCl and KCl are shown in Table 6-1 and 6-2. The other conductivity tables may be found in IEC and other standards. You can also calibrate the sensor with a solution of arbitrary concentration by calibrating it against a standard conductivity meter (we recommend Yokogawa's Personal Conductivity Meter). The reference temperature of both meters should be the same, and as far as possible you should perform the calibration at the reference temperature, as there will otherwise be temperature compensation errors if the temperature compensation functions of the two meters are not exactly the same. When calibration is performed, the cell constant ("Installation Factor") is corrected (see Sec. 5-1-2).

12-4-1-2 Selecting Items for Display

Refer to Sec. 5-1-3 and 5-1-4

1. Selecting Items for Display

You can select and display the following items on the "message" auxiliary display:

• Measured values

• Error messages

• Other messages The shipping-time default is for temperature to be displayed. You can change this default to any item on the list in 2. below.

2. What items can be displayed?

Temperature : Current value Output : Current value Weight% : Current value Installation Factor : See Sec. 6 for Calibration, or Sec. 5-1-2 for Installation Factor

adjustment Reference Temperature : See Sec. 5-3-3 for Reference Temperature setting Temperature Compensation : For default "standard" temperature compensation, NaCl is displayed

When manual temperature compensation is selected, "T.C. coefficient" is displayed. When matrix temperature compensation is selected, You need to specify "reference temperature", "temperature compensation coefficient", and (non-linear) "compensation characteristic".

3. Examples

You can display output signal value (range 4 to 20 mA) on the "message" auxiliary display to check the value. For example, if :

Measurement range : 0 to 100 S/cm, and Process value : 60 S/cm, then Output value : 13.6 mA is displayed.

IM 12D06A03-01E

Appendix 2-7

12-4-2. Commissioning Mode Settings

12-4-2-1 Output Range Setting

Refer to Sec. 5-2-1

1. What does output range setting involve?

When linear output (linear relationship between conductivity and analog output) is selected, the measurement range corresponding to the 4 to 20 mA DC analog output range must be set.

The default measurement range is 0 to 1,000 mS/cm. The display autoranges up to 1999 mS/cm. Zero suppression and non-linear output characteristic may be set (see Sec. 5-2).

2. Setting zero-suppression for output range

For setting ranges with zero suppression, you must specify two points:

• Conductivity corresponding to 0% of range (4mA DC)

• Conductivity corresponding to 100% of range (20mA DC) The conductivity value corresponding to 0% of range must be no greater than 90% of the value corresponding to 100% of range.

Example: To set range 10 to 100 mS/cm

Default 0% setting is 00.0mS/cm. To change this to 10.0mS/cm, press the Next press four times until the units display is flashing to change the units. Press the Press Default 100% setting is 1000 mS/cm. Press four times until the units display is flashing. Press the Press

ENT

key four times until the units display changes to display 10.0 mS/cm.

key until the units display changes to display 100.0 mS/cm.

to confirm.

key.

Setting non-linear output

With the ISC202 Inductive Conductivity Transmitter you can define a 21-step non-linear-characteristic (transfer function) output table  to provide an analog output proportional to concentration, for example. If you define such a table, then output range setting is disabled/invalid. Refer to Sec. 5-3-3 and 5-3-4 for 21-step-table setting details. You can also display concentration in weight% (rather than conductivity in mS/cm) as described in Sec. 5-3-5.

NOTE:

Output range 4mA and 20mA points can correspond to conductivity values in the range 0 to1999

mS/cm, but the following restrictions apply: *1 1999 mS/cm  | ( 0% setting ) - ( 100% setting ) |  100 S/cm *2 Smaller of settings  90% of larger of settings

12-4-2-2 Setting Hold Functions

Refer to Sec. 5-1-5 and 5-2-2

1. What are HOLD functions?

HOLD functions temporarily hold the output signal, and are typically used to maintain output when the sensor is removed from the measured solution, i.e. to prevent alarms and prevent disturbance to control. HOLD functions are set in Commissioning Mode. You can set H.LST (HOLD LaST value before entering HOLD, e.g. maintenance, mode)  this is typically used when the transmitter is connected to a recorder  or H.FIX (HOLD predetermined fixed value, e.g. so that control and alarms are not adversely affected). The default value is for HOLD to be disabled (OFF).

2. How do HOLD functions operate?

Output HOLD status is set as follows: Under Maintenance Mode (press the MODE key), or Commissioning Mode (press the Under calibration You can also turn on HOLD manually as described in Sec. 5-2-2. When reverting from Calibration, Commissioning, or Maintenance modes to Measurement mode, the user must select whether HOLD should be turned OFF or remain ON.

key)

IM 12D06A03-01E

2-8 Appendix

3. Examples

While washing a reactor, HOLD is turned ON to prevent interference with control. When washing finishes, and a new batch starts, HOLD is turned OFF again and the sensor reverts to conductivity measurement.

4. Auto Return

If AutoReturn functions are enabled, the instrument reverts to measurement mode after a preset time (10 min. by default) Refer to Sec. 5-3-5 User Interface.

12-4-2-3 Temperature Compensation

Refer to Sec. 5-2-3 for details.

1. Why is temperature compensation necessary?

Solution conductivity varies greatly with temperature  in general it varies by about 2%/°C. (Conductivity depends on ion mobility, i.e. on solution composition, concentration as well as temperature). For details, refer to 5-2-3 Temperature Compensation, 5-2-4 First temperature compensation for conductivity , 5-2-5 Second temperature compensation for conductivity .

12-4-2-4 Correcting Zero Offset Error by Calibration in Air (Air Set)

Refer to Sec. 5-3 for details.

1. Why does Calibration in Air correct Zero Offset error?

It compensates for leakage resistance of sensor cable and the like.

2. When is such Calibration required?

You should correct zero offset error by calibration in air at startup time, and when the sensor is replaced.

3. What is the procedure for Correcting Zero Offset Error by Calibration in Air

Dry the sensor (conductivity of air should be effectively zero). Ensure that the sensor is not in an electromagnetic (e.g. radio) field. Enter Service Code 04. When AIR is displayed, touch the YES key, and  after START is displayed  touch the YES key again. After END is displayed, touch the YES key again.

*NOTE: The temperature compensation of NaCl should be selected to confirm zero offset after Air Set.

6. One-point Calibration example

Normally you would do a laboratory analysis when the sensor is installed and use the resulting value to calibrate the transmitter. If the concentration at start-up time is known, then you can use concentration to conductivity tables to determine the conductivity, and use that. For example, suppose that the concentration is known to be 34%, and the transmitter should display the corresponding conductivity which is 772mS/cm: .

12-5. Installation factor adjustment ACCESS CODE : 03 DISPLAY : *C.C. Adjustment:

Adjust the ratio between the measured conductance of the sensor and the specific conductivity of the solution.

Explanation:

The installation factor for the ISC40 detector is the ratio of the measured conductivity of the sensor and the specific conductivity of the solution. This factor varies depending on materials of process piping and the distance between the doughnut sensor and the process piping. If the distance is less than 30 mm, sensor calibration is required before using the ISC40. From the calibration results, the ISC202 will calculate an installation factor corresponding to the installation conditions and use it for conductivity measurement. In case where sensor calibration is difficult to be conducted, enter the manually calculated installation factor into the ISC202 following the instructions below.

- When a sensor is installed in the standard stainless steel holder, ISC40FFJ-S, the installation factor decreases approximately 7%. Reduce the value indicated on the label of the sensor cable by 7%, and then enter the result.

- When a sensor is installed in the standard polypropylene holder, ISC40FFJ-P, the installation factor increases approximately 1%. Increase the value indicated on the label of the sensor cable by 1%, and then enter the result.

- When a sensor is installed in long piping with a distance (D) between the sensor and piping, as shown in the figure below, the installation factor for pipe mounting (reference data when the nominal value is 1.88 cm

-1

) is shown in the graph below. Divide the value indicated on the label of the sensor cable by 1.88 and then multiply the quotient by the value obtained from the table. Enter the result.
