7 Introduction Intended Use M420 Cond Ind is used for measurement of electrical conductivity and temperature in liquids using electrodeless sensors. Fields of application are: biotechnology, chemical industry, environment, food processing, water/waste-water treatment. The sturdy molded enclosure can be fixed into a control panel or mounted on a wall or at a post. The protective hood, which is available as accessory, provides additional protection against direct weather exposure and mechanical damage. The device has been designed for application with electrodeless sensors, in particular for sensors of the InPro 7250 Series. Plain-text messages in a large, backlit display allow intuitive operation. The Sensocheck automatic monitoring of sensor and cables and the Sensoface function for clear indication of the sensor condition provide excellent diagnostics. The internal logbook (TAN SW ) can handle up to 100 entries up to 200 with AuditTrail (TAN SW ). The device provides two parameter sets which can be switched manually or via a control input for different process adaptations or different process conditions (e.g. beer and CIP). Password protection for granting access rights during operation can be configured. Two floating, digital control inputs ( Hold and Control ) are available for external control. The device provides two current outputs (for transmission of measured value and temperature, for example). Approvals for Measurement in Hazardous Locations: M420 Cond Ind: General Safety.

24 Operating Modes Diagnostics Display of calibration data, display of sensor data, performing a device self-test, viewing the logbook entries, display of hardware/software versions of the individual components. The logbook can store 100 events ( ). They can be displayed directly on the device. The logbook can be extended to 200 entries using a TAN (Option). HOLD Manual activation of HOLD mode, e.g. for servicing. The signal outputs adopt a defined state. Calibration Every sensor has typical characteristic values. Calibration is required to supply a correct measured value. The device checks which value the sensor delivers when measuring in a known solution. When there is a deviation, the device can be adjusted. In that case, the device displays the actual value and internally corrects the measurement error of the sensor. During calibration the device is in HOLD mode. During calibration the analyzer remains in the HOLD mode until it is stopped by the operator. Configuration The analyzer must be configured for the respective measurement task. In the Configuration mode you select the connected sensor, the measuring range to be transmitted, and the conditions for warning and alarm messages. During configuration the device is in HOLD mode. Configuration mode is automatically exited 20 minutes after the last keystroke. The device returns to measuring mode. Service Maintenance functions (current source), IrDA operation, passcode assignment, reset to factory settings, enabling of options (TAN). 24

26 HOLD Mode The HOLD mode is a safety state during configuration and calibration. Output current is frozen (Last) or set to a fixed value (Fix). The HOLD mode is indicated by orange display backlighting. HOLD mode, display icon: Output Signal Response Last: The output current is frozen at its last value. Recommended for short configuration procedures. The process should not change decisively during configuration. Changes are not noticed with this setting! Fix: The output current is set to a value that is noticeably different from the process value to signal the control system that the device is being worked at. Output Signal During HOLD: Output current [ma] 21 Output signal for HOLD FIX setting = 21.0 ma Output signal for HOLD LAST setting 4 HOLD active HOLD active Terminating the HOLD Mode The HOLD mode is ended by switching to measuring mode (hold meas key depressed). The display reads Good Bye, after that, the HOLD mode is exited. When the calibration mode is exited, a confirmation prompt ensures that the installation is ready for operation (e.g.: sensor reinstalled, located in process). 26

27 Alarm External Activation of HOLD The HOLD mode can be activated from outside by sending a signal to the Hold input (e.g. from the process control system). HOLD Power supply V AC/DC 10 input M420 HOLD inactive HOLD active V AC/DC V AC/DC Process control system (PCS) Manual Activation of HOLD The HOLD can be activated manually from the HOLD menu.

61 Calibration Please note: All calibration procedures must be performed by trained personnel. Incorrectly set parameters may go unnoticed, but change the measuring properties. Calibration can be performed by: Determining the cell factor with a known calibration solution taking account of the temperature Input of cell factor (e.g. for ultrapure-water sensors) Sampling (product calibration) Zero calibration in air or with calibration solution Temperature probe adjustment Please note: If measurements are performed in fittings with A < 110 mm, be sure to choose a calibration beaker with the same cross-section and of the same material (metal/plastic)! Selecting a Calibration Mode Calibration adapts the device to the individual sensor characteristics. Access to calibration can be protected with a passcode (SERVICE menu). First, you open the calibration menu and select the calibration mode: CAL_SOL Calibration with calibration solution CAL_CELL Calibration by entry of cell factor P_CAL Product calibration (calibration with sampling) CAL_ZERO Zero calibration CAL_RTD Temperature probe adjustment 61

62 Calibration Calibration with Calibration Solution Input of temperature-corrected value of calibration solution with simultaneous display of cell factor. Be sure to use known calibration solutions and the respective temperature-corrected conductivity values (see calibration solution tables in the appendix). During the calibration procedure the temperature must be kept constant. Please note: When using an ARF 210/215 flow-through fitting, you should use the inluded calibration beakers (identical dimensions and materials) for calibration to prevent calibration errors.

Please refer to the Specifications for the nominal cell factor. When measuring in a restricted space, the individual cell factor must be determined.

65 Calibration Product Calibration (Calibration by sampling) For product calibration, the uncompensated conductivity (ms/cm, S/m) is used. During product calibration the sensor remains in the process. The measurement process is only interrupted briefly. Procedure: 1) The sample is measured in the lab or directly on the site using a portable meter. To ensure an exact calibration, sample temperature and process temperature should be the same. During sampling the device saves the currently measured value and then returns to measuring mode. Then, the calibration mode indicator blinks. 2) In the second step you enter the measured sample value in the device. From the difference between the stored measured value and entered sample value, the device calculates the new cell factor. If the sample is invalid, you can take over the value stored during sampling. In that case the old calibration values are stored. Afterwards, you can start a new product calibration. Display Action Remark Select Calibration. Press enter to proceed. Select P_CAL calibration method. Press enter to proceed. Ready for calibration. Hourglass blinks. Display (3 sec) Now the device is in HOLD mode. Take sample and save value. Press enter to proceed. Now the sample can be measured in the lab. 65
