2. A few words in advance

The Conex®DIA-1 is a multipurpose device

designed to carry out high-precision measurements

and controls of pH value, redox potential, chlorine,

chlorine dioxide, ozone, hydrogen peroxide or

peracetic acid.

The integrated controller, the high-resolution

graphics display and the multilingual plain-text user

interface make complicated measuring and control

tasks in water chemistry much easier.

Just a few button inputs lead you to your goal.

The potentiostat helps save even more time, being

automatically matched to the various input variables.

The safety standard of the dosing process is raised

by the automatic open-circuit monitoring of the

current outputs.

The Conex®DIA-1 combines the functions of exact

chlorine measuring and automatic pH value

compensation in one single device. For this purpose,

the Conex®DIA-1 features a pH sensor interface

and an interface for external instrument amplifiers.

Properties of the Conex®DIA-1 measuring amplifier

and controller include the following:

• all control functions including PID and

continuous-action controls

• manual or automatic temperature compensation

• logbook function: chronological recording of

calibration values with date and time

• user coding function as a means of protection

against access by unauthorised persons and for

system administration

• error message function for indication of

non-functioning sensors.

4. General information

These installation and operating instructions

contain all information important for users of the

Conex® DIA-1:

• technical data

• instructions on commissioning, use and

maintenance

• safety information.

Should you require further information or should you

encounter problems that are not handled in sufficient

depth in this manual, please contact Grundfos.

We shall be pleased to support you with our

comprehensive know-how in the fields of measuring

and control technology as well as water treatment.

We always welcome suggestions on how to optimise

our installation and operating instructions to satisfy

our customers.

5. Applications

The Conex®DIA-1 instrument amplifier and

controller is suitable for measuring chlorine (Cl2),

chlorine dioxide (ClO2), ozone (O3), hydrogen

peroxide (H2O2), peracetic acid, pH or redox

potential and for controlling these variables using

appropriate actuators within the applications

described in this manual.

6. Safety

6.1 Obligations of the owner/operations

manager

The owner/operations manager must ensure that

persons working with the Conex®DIA-1 instrument

amplifier and controller fulfil these requirements:

• They are acquainted with the regulations

concerning working safety and accident

prevention.

• They have been trained in use of the device.

• They have read and understood the warning

information and handling symbols.

The owner/operations manager is also responsible

for ensuring that this manual is kept in the immediate

vicinity of the device and is always available for the
