  • Page 39: Sensor Wiring

    The EXA SC202 can be used with a wide range of commercially available sensor types if provided with shielded cables, both from Yokogawa and other manufacturers. The sensor systems from Yokogawa fall into two categories, the ones that use fixed cables and the ones with separate cables.

  • Page 40: Other Sensor Systems

    Where a convenient installation is not possible using the standard cables between sensors and transmit- ter, 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 neces- sary to ensure that the specifications of the system are not compromised.

    Parameter setting 5-5 5-2-4. Temperature compensation 1. 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, concentra- tion and temperature range.

    6. CALIBRATION 6-1 When is calibration necessary? Calibration of conductivity/resistivity 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 can be entered directly in service code 03 (section 5-3-1).

  • Page 69: Maintenance

    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 NOTE: Maintenance advice listed here is intentionally general in nature.

    Troubleshooting 8-1 8. TROUBLESHOOTING The EXA SC202 is a microprocessor-based analyzer that performs continuous self-diagnostics to verify that it is working correctly. Error messages resulting from faults in the microprocessor systems itself are few. Incorrect programming by the user can be corrected according to the limits set in the following text. In addition, the EXA SC202 also checks the sensor to establish whether it is still functioning within speci- fied limits.

    12. APPENDIX 2 12-1. Preface Feasible combinations of the SC202G conductivity transmitters with different styles of the PH201G dis- tributor are listed in the table below. The distributor has the usual distributor functions (supply power to transmitter, receive current output from transmitter, and provide analog output) as well as contact output functions (maintenance, wash and fail status signals).

Set cell constant (service code 03) Code 3 *0.10xC First select a multiplying factor, and then set the constant in consideration of this fac- tor. The position of the decimal point can be selected after the first digit has been set (when the decimal point is flashing).

    2-6 Appendix 12-4-4. Error setting (service code 53) Code 53 *Err01 to 13 Error message configuration: Two different types of failure mode namely, Hard fail and Soft fail can be set. Hard fail gives a steady FAIL flag in the display. When the distributor PH201G (Style B) is used and its communication is enabled in Service Code 60, the fail contact of PH201G (Style B) is closed.
