1. INTRODUCTION 1-1. Application The model ISC402G inductive conductivity mains powered converter is designed for use with the Model ISC40 sensor. This revolutionary conductivity measuring system features ± 0.5% accuracy over a wide range of conductivity values (1 to 2,000,000 µS/cm) and process temperatures (-30 to 150 °C/22 to 302 °F) without changing cell constant or recalibration.
2 specific conductivity and a constant factor that is determined by the geometry of the sensor (length divided by surface area of the hole in the toroid) and the installation of the sensor. There are 2 toroids mounted in the "doughnut" shaped sensor. The liquid also flows through the second toroid and therefore the liquid turn can be considered as a primary winding of the second ring transformer. The current in the liquid will create a magnetic field in the second toroid.

13 3-3-2. Wiring of power supply 3-3-2-1. General precautions Make sure the power supply is switched off. Make sure that the power supply is correct for the specifications given. Remove the front cover by unscrewing the 4 captive screws. Check the type-plate on the instrument for the correct supply voltage. Local health and safety regulations may require an external circuit breaker to be installed. The instrument is protected internally by a fuse.
14 3-3-4. Wiring the contact signals 3-3-4-1. General precautions The contact output signals consists of voltage-free relay contacts for switching electrical appliances (SPDT). They can also be used as digital outputs to signal processing equipment (e.g. PLC). It is possible to use multi-core cables for the contact in-and output signals and screened multi-core cable for the analog signals. 3-3-4-2. Contact outputs The 4 contact outputs can be wired to your own requirements, refer to Fig. 3-7.
15 4. START-UP The EXA ISC402G transmitter offers great flexibility to let the user have one hardware version for a multitude of different applications. The software has been programmed for a "general application". It will be necessary for the user to program the instrument to his specific requirements or application. Although programming the transmitter is simple, some preparation is necessary.
16 4-3. Temperature (TEMP) compensation The factory adjustment for automatic temperature compensation is the standardized NaCl algorithm according IEC 746-3. For concentrated electrolytes this may not be accurately compensate for process temperature variations. The ISC402G gives the user 4 methods of optimizing the temperature compensation: 4-3-1.Field calibration of (linear) temperature compensation The procedure is described under §6-4. 4-3-2.
17 4-6.
18 4-7. Cleaning If it is necessary to clean the outside of the EXA housing, this should done using only a soft cloth and household detergent. DO NOT USE corrosive or abrasive cleaners. 4-8. Battery 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.

20 1. When is calibration necessary? Initially follow the procedure given in item §4-4-1 for air calibration when setting up the instrument for the first time. Calibration of conductivity instruments is not normally necessary as the conductivity cells are manufactured to close tolerances and do not alter in use. If the cell has severe fouling or been subject to abrasion (possibly during cleaning) it may be necessary to calibrate.
21 With this method the sensor is not removed from the process. This method is the most convenient method of calibrating the ISC402G transmitter. Since the sensor is immersed in the process, errors caused by installation characteristics are compensated for. NOTE: The standard instrument used as reference method must be accurate. Yokogawa recommends that the Model SC82 pocket conductivity meter be used for this purpose. 3.

25 5-3. USE OF HOLD FUNCTION 1. What is HOLD? Hold is a function which freezes the output signal temporarily, it is normally used during maintenance to prevent unwanted controller reaction when the cell is removed from the solution being measured. The HOLD function must be commissioned from the programming menu before it can be switched on or off. See commissioning the hold function for more details. NOTE: AUTO RETURN will switch off HOLD after 10 minutes, see §7-10. 2.

27 5-4. ADJUSTING THE SET POINTS NOTE: It is only possible to access this function at the maintenance level if it has been activated with service code 24. This function gives the operator the facility to change the setpoints at the maintenance level. It can only be used if it has been activated in service code 24. The protection of the set points is to prevent unauthorized access to these functions. NOTE: 1.

29 6-1. ADJUSTING THE SET POINTS 1. What are setpoints? In general the contact outputs of the EXA ISC402G can be used to signal extraordinary situations in the process. The alarm contacts are switched if the comparison of the changes process value to a fixed setpoint meets the condition of the alarm function (higher or lower). These setpoints are programmed in this section. One of the advantages of a micro-processor instrument is, that it is fairly simple to change the function of the contact outputs.

31 6-2. OUTPUT RANGE ADJUSTMENT 1. What is the output range? The default value of the software defines the output range of 4-20 mA = 0-1000 mS/cm. This display will always show the full range of the instrument from 0-2000 mS/cm. Maximum resolution is achieved by auto-ranging, where the position of the decimal point and measuring units (microSiemens/milliSiemens) are moved to best fit the actual value. For control or recording the current output can be ranged to a specific part of the total measuring span.

33 6-3. SET-UP HOLD FUNCTION 1. What is HOLD? HOLD is a function freezing the output signal temporary, during normal maintenance, preventing unintended alarm or colour actions to occur. Two possibilities are generally used: - Keep the output at the LAST (H.LST) value just before the start of maintenance. This can only be used when a recorder is connected. - Keep the output at preset FIXED (H.FIX) value which will not cause any of the alarms to go off or any controlling action to be taken.

35 6-4. TEMPERATURE COMPENSATION 1. Why is temperature compensation necessary? The conductivity of a solution is very strongly influenced by 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; solution composition, concentration and temperature range.
36 4. Calculating the approximate temperature coefficient If the temperature coefficient of a liquid to be measured cannot be found, measure the conductivity of the liquid at two temperatures between 10 and 30°C with the temperature coefficient set to 0.00 and use the following equation to calculate an approximate temperature coefficient (α).

39 6-5. AIR SET 1. What is AIR SET procedure? The AIR SET procedure is a routine to compensate for the small zero current due to the inductive coupling of the sensor, cabling and transmitter. 2. When is an AIR SET procedure necessary? AIR SET is done only once during Start-Up, and when a new sensor is connected to a transmitter. If the user wants to make full use of the systems capabilities and requires accurate measurement down to 0.5 µS/cm, this simple routine will optimize the performance. 3.
