1 INTRODUCTION

1.1 Before You Begin

Thank you for purchasing the Alpha COND 560 Controller. The construction of the Alpha COND 560 Controller employs leading edge tech-

nology and complies with safety regulations currently in force. Notwithstanding this, improper use could lead to hazards for the user or a third-party, and/or adverse effects on the plant or other equipment. Therefore, the operating instructions must be read and understood by the persons involved before working with the Conductivity Controller.

The instruction manual must always be stored close at ha nd, in a place accessible to all people working with the Conductivity Controller.

If you have questions, which are not or insufficiently answered in this instruction manual, please contact your authorized supplier. They will be glad to assist you.

1.2 Intended Use

Alpha COND 560 Controllers are intended solely for Conductivity and temperatur e measurement, as described in this instruction manual.

Any other use, or use not mentioned here, that is incompatible with the technical specifications is deemed inappropriate. The oper ator is solely responsible for any damage arising from such use.

Other prerequisites for appropriate use include: – Comply with the instructions, notes and requirements set out in this instruction

manual.

– Comply with all local safety regulations concerning safety at work. – Comply with all information a nd warnings in the documentation de aling with the

products used together with the Conductivity Controller (housing, sensors, etc.).

– Comply with the local environmental and operational conditions.

1.3 Safety Instructions

• The Alpha COND 560 Controller should be installed and operated only by personnel familiar with the instrument and who are qualified for such work.

• A defective Conductivity Controller must neither be installed nor put into service.

• The Alpha COND 560 must only be operated under the specified operating conditions (see section 6).

• The Alpha COND 560 must not be repaired by the customer.

• No modifications to the Alpha COND 560 are allowed. The manufacturer/supplier accepts no responsibility for damage caused by unauthorized modifications. The risk is borne entirely by the user.

1.4 Taking Out of Service / Correct Disposal of the Unit

Taking out of Service

• First disconnect the unit from the power supply and then undo all electrical connections.

• Remove the unit from the wall.

Correct Disposal of the Instrument

When the Alpha COND 560 is permanently taken out of service, obey the local environmental regulations for correct disposal or send the instrument to your local distributor, they will take care of proper disposal.

2 GETTING STARTED

2.1 Description of Instrument

The Eutech Instruments’ Alpha CON 560 Controller is used for measuring conductivity and temperature values. The controller can be used for applications such as water treatment and controlling, galvanic-decontamination, chemical processing, food processing, clean or wastewater control and neutralization processes.

The controller has many user-friendly and safety features which include:

• Push-button keypad for calibration and setup

• Built-in non-volatile memory to ensure that calibration and other

information are not erased if power supply fails

• Menu-driven program that simplifies setup

• Automatic temperature compensation (ATC)

• Manual temperature compensation setting without the ATC probe, with

independent setting for calibration and process temperature

• Large dual display L CD for easy reading with clear multiple annunciators, operational mode indicators and error indicators

• Two switching contacts as set-point relays

• Limit (on/off) control mode

• Separately adjustable high and low set-point hysteresis (dead bands) to

prevent chattering of relays around the set points

• 0 to 2000 seconds time delay adjustment on all relays – minimizes false alarms

• Backlight LCD display

2.2 Measurement System

A typical measurement system consists of:

• A conductivity process controller

• A conductivity sensor with integrated or separate Pt100/Pt1000

temperature sensor

• An appropriate measurement cable

• An immersion, flow or process assembly

• A final control element such as pump or valve

2.3 Connecting Peripherals

2.3.1 Connection Terminals Remove Back Cover:

Remove the screws from the four corners at the back of the conductivity controller. Remove the back cover. The connectors are exposed on the back PCBA as shown in the Figure 1 below.

Connectors:

• J11 – 24V DC power connector

• J8 – 9V DC power connector (1.2mm diameter)

• J9 – Relay connections

• J10 - Conductivity electrode & Temperature probe connections (wiring

has to be done in the detachable connector

2.3.2 Switching Between PT100 & PT1000 Temperature Sensors

The controller supports both Pt100 & Pt1000 (2-wire or 3-wire) temperature sensors. The default factory setting is Pt100. If you need to use Pt1000 temperature sensor, you have to change the jumper setting (J7) as described below.

Remove Back Cover:

Remove screws from the four corners at the back of the conductivity controller. Remove the back cover.

Remove Back PCBA:

Remove the screw located center of the back PCBA (Figure 1). Detach the back PCBA from the controller. Turn over the back PCBA. Locate J7 jumper o n the inner side of the back PCBA as shown in figure 2 below.

Set Jumper J7:

Set the J7 jumper to required sensor (Pt100 or Pt1000) type

2.3.3 Connecting Conductivity Electrode

Any industrial conductivity probe (2-cell or 4-cell) can be connected to the conductivity controller.

2-Cell Conductivity Probe:

1. Short Pin 1 & 2 of J10 connector using a jumper wire.

2. Connect CON low input wire (white) to Pin 2 of J10 connector.

3. Connect CON high input wire (black) to Pin 3 of J10 conn ector.

4. Short Pin 3 & 4 of J10 connector using a jumper wire.

4-Cell Conductivity Probe:

5. Connect CON low input wire (black) to Pin 1 of J10 con nector

6. Connect CON low input wire (white) to Pin 2 of J10 connector.

7. Connect CON high input wire (orange) to Pin 3 of J10 connector.

8. Connect CON high input wire (blue) to Pin 4 of J10 con nector.

2.3.4 Connecting Temperature Probe

For Automatic Temperature Compensated (ATC) conductivity readings, an in-built temperature sensor is usually integrated with industrial conductivity probes. Alternatively, a separate 100Ω Pt RTD temperature probe (2-wire or 3-wire) can be connected to the controller.

3-Wire Probe:

1. Connect PT100 compensate wire to Pin 5 of J10 connector.

2. Connect PT100 sense wire to Pin 6 of J10 connector.

3. Connect PT100 GND wire to Pin 7 of J10 co nnector.

2-Wire Probe:

4. Short Pin 5 & 6 of J10 connector using a jumper wire.

2.5 Display & Keypad

2.5.1 Display Overview

The Liquid Crystal Display (LCD) of Alpha COND 560 conductivity controller has two alpha-numerical displays (Upper and a Lower).

• Upper display: Measured conductivity value is d ispl aye d when the c ontr oller is

in normal operation (measurement) mode.

• Lower display: Measured temperatur e value is displayed when the controller

is in normal operation (measurement) mode. In conductivity calibration mode, measured conductivity values are displayed here.

The two displays indicate function names, options & settings in Setup m ode. Refer ‘Appendix 4 - Abbreviations Used in LCD’ for more details.

The LCD also consists of various mode indicators, status annunciators and unit of measurement indicators.
