1 INTRODUCTION

1.1 Description of Unit

Thank you for purchasing the ¼ DIN Alpha COND 1000 series Conductivity process controllers. This unit is used for measuring the Conductivity of a solution, either in micro-Siemens or milli-Siemens, one at a time, and the operational mode is switchable from the menu. You can use this unit to measure Conductivity with limit control. This controller has many user-friendly and safety features which include:

• Menu-driven program that simplifies set-up

• Ten ranges of Conductivity measurements-software selectable (Appendix

2).

• Built-in memory backup to ensure that calibration data and other information are not erased if power supply fails

• Automatic temperature compensation (ATC) with Pt100 or Pt 1000

• Manual temperature compensation with independent setting for

calibration and process temperature

• Temperature coefficient variable between 0.00 to 10.00 % per pure water compensation curve stored in memory. Reference temperature at 25oC.

• 0 to 1999 second time delay adjustment on all relays – minimise false alarms

• Separately adjustable high and low set point hysteresis (dead bands) prevents chattering of relays around the set points. Selectable Filter function stabilises rapid measurement changes

• Four operating modes: limit, display monitor , proportional pulse length or proportional pulse frequency control.

• Large dual display LCD for easy reading with clear multiple annunciators, alarm status and operational message annunciators

• Two switching contacts as set-point triggering relays and an alarm output relay

• Separate alarm relay alerts you when set points have exceeded the limits and if the Pt100/Pt1000 wires are broken or disconnected during the ATC function

• Hold function freezes output current (0/4...20mA) and releases control relays

• LED indicators signal control activities to monitor controller status from a distance

• Protection against electromagnetic interference - galvanically isolated

0/4 - 20mA output provides safety for data logging and control purposes

1.2 Applications

Use this controller in panel mounted enclosures for applications in water treatment and demineralization, waste water treatment and neutralization processes.

5 MEASUREMENT

5.1 Display in Measurement mode

When the controller is initially powered on, it automatically enters into the Measurement mode after the large dual LCD displays all segments briefly.

The upper display shows the measured Conductivity value, while the lower display shows the temperature value. Annunciators at the right side of the display indicate whether the controller is set for μS or mS measurement. Similarly annunciators or icons at the top or left side of the display shows the current status of controller, e.g. “HOLD”, “SETUP”, “MEAS”, “CAL”, “READY”, etc.

5.1.1 Check electrode performance

To read current electrode slope and offset values without changing them:

1) Press the CAL key followed by the ENTER key without adjusting the security

code (leave code at “000”). The upper display shows the condition of the probe. The lower display reading shows the temperature reading.

Note: If security code is changed to a value other than “000”, pressing the ENTER key will return to the Measurem ent mode, without displaying electrode

information.

2) Press the ENTER key a second time to return to Measurement mode.

5.1.2 Checking set points

To read current set point values without changing them:

• Press the RELAY Selection (Rel A / Rel B) key. The upper display shows the set point for Relay A; the lower display shows “SP1”.

• After two seconds the upper display shows the set-point value for Relay B; the lower display shows “SP2”.

• After an additional two seconds, the controller returns to the Measurement mode.

Operating Instructions Thermo Scientific Alpha COND 1000

5.2 Security Codes

This controller has two levels of security protection with separate security codes. The first level allows entry into the Calibration mode: security code = 11; the second allows entry into the SETUP mode: security code = 22.

The security codes protect the controller from unauthorised tampering of its current setting. The parameters cannot be changed unless the security code is entered.

5.2.1 How to enter and change parameters in Calibration mode

1) Press the CAL key. The upper display shows “000” and the lower display shows “C.Cd” to prompt the user to enter the Calibration security code.

6 CALIBRATION MODE

You can reach the Calibration mode directly from the Measurement mode by pressing the CAL key and entering the Calibration security code. You can also reach the Calibration mode from the Advanced Setup mode.

6.1 Conductivity Calibration

Calibration is always carried out in the specific range selected. The Conductivit y Controller allows a one-point calibration.

1) Enter Calibration mode. While in the Measurement mode, push the CAL key and scroll to Calibration code “11”. Push the ENTER key again. The upper display reads “CAL” and the lower display shows “Con”.

2) Press the ENTER key. The controller displays its last set Cell Constant (k) of the cell as a percentage of the theoretical value. Using the ▲and ▼ keys, the value can be set to anywhere from 80 to 120% (e.g. real cell constant is 0.98 with nominal =1, enter 98%). . Press the ENTER key once again to carry out calibration.

3) Immerse the Conductivity cell in a suitable standard solution, whose value is within the measurement range selected in the controller. Agitate the Cell in the solution to remove any trapped air-bubbles.

Note: The calibration standard should have a value that is between 20% to 100% of the range selected. For example, if the range in the controller is selected to be 2000 µS (range 6), then the calibration standard value should be 400 µS to 2000 µS.

4) Once the reading has stabilized, use the ▲ or ▼ keys to adjust the measured value to that of the standard solution. Press the ENTER key to accept the value and the controller displays the revised condition of the probe. The lower display shows the factor “FCt” while the upper display shows the ratio of ideal to adjusted calibration value.

Note: The acceptable calibration window is ±40% of the displaye d (default) value. If the display is 1000 µS, the values to which it can be adjusted is 6 00 to 1400 µS. If there is calibration error, the controller displays “ERR” annunciator. To re-calibrate repeat step 3. To exit from calibration, push both ▲ and ▼keys (escape) to resume to Measurement mode.

5) Press the ENTER key. If you entered the calibration mode using the CAL key, the controller will return to the Measurement mode. If you entered the calibration mode from the Advanced Set-up mode, the controller will return to the subfunction menu.

7.3.4 Selecting a hysteresis (dead band) value

Hysteresis prevents rapid contact switching if your value is fluctuating near the set point. It does this by overshooting the set point value to a specified hysteresis value

Example: You have set your set point 1 (Lo) at 100.0 μS and your hysteresis limit value is at 20 μS. If your measured value undershoots the low set point of 100.0 μS, the controller’s relay activates, which in turn activates an external device such as a pump or valve. The actions of the external device will cause the value to r ise above

100.0 μS. When the value has increased to 120.0 μS, the relay, and hence the

pump will switch off. Default hysteresis value in the full scale conductivity range of 2,000 µS (see

Appendix 2) is 20 µS. You can set the hysteresis value from 0 to 10% of the full scale conductivity range.

1) Follow directions in 7.3.1 to enter Control Relay

mode.

2) Press the ENTER key. Scroll with the ▲ or ▼ keys

until the upper display shows the hysteresis (dead band) value and the lower display shows “HYS”.

3) Press the ▲ or ▼ keys to enter your hysteresis

value for Set point 1 (or Set point 2). Your controller will activate at the value you select. Note: All settings for SP1 and SP2 are completely independent of each other.

4) Press the ENTER key to confirm your selection.

5) Proceed to 7.3.5, or return to Measurement mode by pressing the ▲ and ▼

keys simultaneously (escape).

NOTE: Please refer to Appendix 3 for a graphical representation of the Hysteresis.
