1 INTRODUCTION

Thank you for purchasing a CON 200 ⅛ DIN Conductivity Controller. This controller is part of a series of quality process controllers available from Eutech Instruments. These sturdy, economical conductivity controllers are designed with the features and reliability of a much more expensive instrument.

Your controller includes:

• Removable terminal blocks for easy connections;

• Two mounting brackets for easy panel mounting;

Some features of this controller are:

• Two set point, two SPDT relay operation

• Scrolling, 14-segment LED guides user easily through setup functions

• Reliable power supply from 85 to 260 V AC, 50/60 Hz or DC withstands

voltage fluctuations

• Push-button operation from the front panel

• Single-point calibration for each individual range

• Adjustable hysteresis band prevents rapid contact switching around set-point

• Selectable automatic or manual temperature compensation

• Two-level password protection

• Removable terminal strips for quick and easy connections

• Built-in memory backup retains setup even if power fails, and lets you

configure unit before installation

• Isolated 4-20 mA output for remote monitoring or hard copy recording

2 SAFETY INFORMATION

The Eutech Controller/Transmitter shall be installed and operated only in the manner specified in the Instruction manual. Only skilled, trained or authorized person should carry out installation, setup and operation of the instrument.

Before powering up the unit, make sure that power source it is connected to, is as specified in the top label. Failure to do so may result in a permanent damage to the unit.

The unit has live and exposed parts inside. If it has to be opened, make sure that the power to the unit is off and disconnected.

The unit is Fuse protected. In the event the fuse has to be replaced, use only those as specified in the manual.

The degree of protection against electric shock will be achieved only by observance of the corresponding installation rules.

3.3 Wiring

Caution: Ensure electrical mains are disconnected before proceeding.

1. Connect the power supply to the three-pin terminal block

• VAC live wire = 1

• VAC neutral wire = 2

• VAC protective ground wire = 20 OR 21

alpha CON 200 controller accepts voltages from 85 to 260 VAC, 50/60 Hz or DC.

2. Connect the Pt 100 leads to terminals 13 to 15 of the seven-pin terminal block. Either wire can be connected to either terminal. Terminals 13 and 14 must be shunted unless using a 3-wire RTD.

NOTE: CON 200 is factory set for Automatic temperature compensation. MTC can be selected in Program P4.0.

3. Power on the controller. The display automatically shows the Conductivity reading, the µS and ‘MEAS’ annunciators lights.

NOTE: In the event Pt 100 is not connected or the connection is broken in the ATC mode, the display flashes ‘OR’ to alert you.

3.4 Panel-mounting the controller

The supplied mounting hardware allows surface mounting to all panels and protective enclosures. Mounting cut-out size is 91 x 45 mm.

To attach the mounting to the controller:

1. Align the catch to the side of the controller, and insert threaded rods through

catch.

2. Screw the threaded-rod through the catch in a clock-wise direction. Tighten

until the catch holds the controller firmly against the back of the panel or protective housing. Repeat on the other side.

4 MEASUREMENT MODE

Press MODE to toggle between:

• Conductivity measurement mode and

• Temperature measurement mode

Conductivity Measurement Mode

The controller displays the selected Conductivity range number, R X (X ranges from 1 to 8), for 2 seconds before displaying the Conductivity measurement.

Conductivity Range Range No., R Resolution Cell Constant

0.00 – 20.00 µS/cm 1 0.01 µS/cm 0.1

0.0 – 200.0 µS/cm 2 0.1 µS/cm 0.1

0.0 – 200.0 µS/cm 3 0.1 µS/cm 1 0 – 2000 µS/cm 4 1 µS/cm 1

0.00 – 10.00 mS/cm 5 0.01 mS/cm 1

0.0 – 200.0 mS/cm 7 0.1 mS/cm 1

0.0 – 200.0 mS/cm 8 0.1 mS/cm 10

Temperature Measurement mode

Press MODE key once to view the temperature measurement. The display shows ATC (Automatic Temperature Compensation) or MTC (Manual Temperature Compensation), then the current measured temperature (for ATC) or the set temperature (for MTC). The temperature.

NOTE: After pressing the MODE key to display Temperature, if there is no further key-press, the Controller will automatically revert to Conductivity Measurement mode after about 30 seconds.

See Setup program P4.0 for further instructions.
