Parameter setting 5-1 5. PARAMETER SETTING 5-1. Maintenance mode 5-1-1. Introduction Standard operation of the EXA transmitter involves use of the Maintenance (or operating) mode to set up some of the parameters. Access to the maintenance mode is available via the six keys that can be pressed through the flexible window in the instrument front cover. Press the ‘MODE’ key once to enter this dialog mode.

5-6 Parameter setting 5-2. Commissioning mode In order to obtain peak performance from the EXA ISC202, you must set it up for each custom application. mA *OUTP mA *HOLD *TEMP.1, 2 *SERV : mA output is set as default to 0-1000 mS/cm. For enhanced resolution in more stable measuring processes, it may be desirable to select for example 0-100 μS/cm range. : The EXA ISC202 transmitter has the ability to ‘HOLD’ the output during maintenance periods.
Parameter setting 5-7 mA 5-2-1.
5-8 Parameter setting mA 5-2-2. HOLD * Here HOLD is enabled/disabled. When enabled: • The analyser’s output will be set to HOLD when entering Maintenance-, Commissioning- or Service menu. • Up on exiting one of the menus, the user is asked if HOLD should remain activated.
Parameter setting 5-9 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.
5-10 Parameter setting Calculation example Calculate the temperature co-efficient of a liquid from the following data. Conductivity 124.5 μS/cm at a liquid temperature of 18.0 °C and a conductivity 147.6 μS/cm at a liquid temperature of 31.0 °C. Substituting the data in the above formula gives the following result. α= 147.6 - 124.5 x 100% = 1.298%/ ºC 124.5(31.0 - 25) - 147.6(18.0 - 25) Set the temperature coefficient in the EXA transmitter. 2-C.

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.
6-2 Calibration 6-2. Calibration procedure MODE MEASURE CAL DISPLAY HOLD YES NO MODE ENT Press the MODE key The legend CALIB appears, and the YES/NO key prompt flags flash Put the sensor in standard solution Press YES Set the value using the key Select the flashing digit with the key Increase it’s value by pressing the key When the correct value is displayed, press ENT to enter the change After briefly displaying WAIT, the CAL.
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.
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.

Appendix 2-5 12-4. Quick reference for parameter setting Preparation for operation entails deciding maintenance-mode settings and measurement range setting-related issues. Service level (mode) settings are described in Sec. 5-3. Shipping-time measurement parameter setting defaults are shown in Table 12-1. In general there is no need to change these defaults. Table 12-1 Default values of parameters.

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.

2-18 Appendix 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: .
Appendix 2-19 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.
