  • Page 6: General Description & Theory Of Operation

    GENERAL DESCRIPTION & THEORY OF OPERATION This instrument allows conductivity measurements without any electrical contact between electrodes and process fluid. The measurement is based on inductive coupling of two toroidal transformers by the liquid. The instrument supplies a high frequency, reference voltage to the “Drive Coil”, and a strong magnetic field is generated in the toroid.
  • Page 7 For an inductive cell, the cell constant is defined as the measured conductivity, obtained by making a loop through the sensor with a resistor R, multiplied by that R value. The cell constant depends only on the sensor geometry. However, when the probe is immersed in a liquid, the induced current in the solution is affected by the piping or any other container where the probe is inserted.
  • Page 8 The main features of the HI 720 controller series include: • Measurement and control of conductivity or concentration • Concentration can be measured as usual TDS (fixed ratio) or through custom conductivity/temperature/concentration curves • Customizing temperature coefficient table and NaCl temperature compensation according to IEC 746-3, in addition to the standard linear compensation •...

  • Page 30 TDS values in setup (excluding the temperature compensation table and the concentration curves) are automatically updated, so that the “new value / new f.s.” = “previous value / previous f.s.“ A life check error is generated if the reading does not vary more than 0.5% of the current f.s.
  • Page 31 (17) If the relay 1 (or relay 2) mode is set to “Control-setpoint 1”, the analog output 1 can not be set to “Control-setpoint 1”, and vice versa. Similarly, if the relay 1 (or relay 2) mode is set to “Control-setpoint 2”, the analog output 2 can not be set to “Control-setpoint 2”, and vice versa.
  • Page 32 If the item P .14 has been set to “222”, no expiration date check will be done. (26) This item is particularly useful in noisy environment, to filter measurement spikes and avoid undesired activations of the on/off control contacts. The relay energizes and de-energizes only if the corresponding threshold is overridden for more than the configured contact action delay (see below graph: “dly”...
  • Page 33 (30) This parameter set the number of latest measurements used to calculate an average value. The average is calculated both for conductivity/concentration and temperature. The averaged conductivity/concentration value is then used both for displaying and control. (31) When the concentration unit is changed, all items from C.00 to C.34 and from O.12 to O.15 are reset to the default values.

  • Page 34: Calibration Mode

    alibration The controller is factory calibrated for temperature as well as for the analog outputs. The user should periodically calibrate the instrument for the conductivity range. For greatest accuracy, it is recommended to standardize the probe with a cali- bration solution close to the expected sample value. •...
  • Page 35 zero calibration, and the “Wait ...” message will flash on the LCD. After com- pleting the procedure, the meter will ask for confirmation to proceed with the previously selected calibration point. • Press CFM to confirm and immerse the conductivity probe & temperature sen- sor (if a separate temperature probe is used) in the proper calibration solution.
  • Page 36 • Use a Checktemp or another calibrated thermometer with a resolution of 0.1° as reference thermometer, and immerse the temperature sensor in the ice bath as near to the Checktemp as possible. • Confirm the calibration option and the instrument will start the automatic cali- bration of the first point.

  • Page 37: Control Mode

    The control mode is the normal operational mode for this meter. During control mode HI 720 fulfills the following main tasks: • convert information from conductivity and temperature inputs to digital values, and show them on the display • control relays and generate the analog outputs as determined by the setup configuration •...
  • Page 38 If the “hold mode” is selected for the relay, then it is energized only when the meter is in hold mode. In this case there is no time boundary for the relay ON state. Relays 3 and 4 can be configured to operate in three modes: 1.
  • Page 39 “trial & error” tuning procedure must be applied to get the best possible control for each process. The target is to achieve a fast response time and a small overshoot. Many tuning procedures are available and can be applied to HI 720.
  • Page 40 A simple and profitable procedure is described in this manual and can be used in almost all applications. The user can vary five different parameters, i.e. setpoint value (S1 or S2), devia- tion (D1 or D2), reset time, rate time and proportional control mode period T Note The user can disable the derivative and/or integrative action (for P or PI controllers) by setting Td = 0 and/or Ti = MAX (Ti), respectively,...
  • Page 41 Example: • Max. slope = 30 mS / 5 min = 6 mS/min • Time delay = Tx = approx. 7 minutes • Deviation = Tx * 6 = 42 mS • Ti = Tx / 0.4 = 17.5 min •...
  • Page 42 The Fail Safe mode is accomplished by connecting the external alarm circuit between the FS•C (Normally Open) and the COM terminals. This way, an alarm will warn the user when measurement overtakes the alarm thresholds, power fails, or the wire connecting the process meter with the external alarm circuit breaks. Note To activate the Fail Safe feature, an external power supply must be connected to the alarm device.

  • Page 43: Idle Mode

    While in idle mode, the device only performs measurements. It does not activate relays or generate a control signal to the analog output(s). In a normal situation the alarm relay is energized (no alarm condition) and the green LED is ON. The red LED is also fixed ON to warn users the device is not controlling the process, while the yellow LEDs are OFF.

  • Page 44: Diagnostic Mode

    iagnoStiC The diagnostic mode allows the user to check if some errors are still active on the controller, or view the event log file. To enter (and exit at any time) this mode, press the DIAG key. Select the desired option with the up & down arrow keys, and then confirm the selection by pressing CFM.

If the description of the previous and/or new val- ue is too long to be displayed, an index between square brackets is used. This index indicates the position of the value in the list of available op- tions for the parameter.

  • Page 46: Temperature Compensation

    TEMPERATURE COMPENSATION If the setup item b.01 is set to ATC, then an automatic temperature compensa- tion of the conductivity readings will be performed using the temperature values acquired through the Pt100/Pt1000 input. If the temperature probe is not connected or it provides an invalid temperature (outside the -30 to 130°C range), the instrument will generate a “broken tem- perature probe”...

  • Page 51 After the cause which made the instrument enter the hold mode expires, the device exits the hold mode, but control and alarms remain disabled for a user-selectable delay (0 to 99 seconds). In that situation, measurements are normally acquired, displayed and recorded through the analog or RS485 output. Note Alarms (alarm relay, red LED, fault currents) are not disabled if the hold mode has been triggered by an error and no other trigger source...

  • Page 52: In-Line Cleaning

    IN-LINE CLEANING The cleaning feature allows an automatic cleaning action of the electrodes. To perform cleaning, the controller activates an external device (pump). Cleaning actions never take place if no relay is configured for cleaning. Moreover, the Advanced Cleaning requires both relays 3 and 4 to be configured for it. Cleaning can be of two types: •...
  • Page 53 • Hold mode end delay: if the device was controlling, then the hold mode end delay must expire before restarting control. If the device is in normal measurement mode, when performing a cleaning action, the display shows a countdown for the seconds remaining to the cleaning action end, and starting with the total cleaning time.

  • Page 54: Communication
