2. A few words in advance
The Conex®DIA-1 (Dosing Instrumentation
Advanced with 1 input) multipurpose measuring
amplifier and controller you have just purchased
uses the company’s leading-edge measuring
technology.
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, fluoride
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.

12. Commissioning / electrical
connections 1. Remove the terminal cover on the front of the
device.
2. Use the appropriate cable feedthroughs and
tighten the screws carefully.
3. Connect the cables used to the terminals
according to the Conex®DIA-1 terminal
assignment.
4. Close the terminal cover again with correctly
positioned gasket.
Warning
Switch off the power supply before
installing!
Enclosure class IP65 is only
guaranteed with the front panel of the
terminals enclosure closed and with
appropriate cable glands or dummy
caps.
Warning
Switch off the power supply before
connecting the power supply cable and
the relay contacts! For safety reasons,
the protective conductor must be
connected correctly!
Observe the local safety regulations!
Protect the cable connections and
plugs against corrosion and moisture.
Caution
Before connecting the power supply
cable, check that the supply voltage
specified on the nameplate
corresponds to the local conditions!
An incorrect supply voltage may
destroy the device!
To guarantee electromagnetic
compatibility (EMC), the input and
current output cables must be
screened.
Connect the screening to the screen
ground on one side.
Refer to the wiring diagram! Route the
input, current output and power supply
cables in separate cable channels.
Caution
Enclosure class IP65 is only
guaranteed if the terminal cover is
correctly sealed! Do not damage the
gasket on the terminal cover!
The gasket on the terminal cover must
be positioned precisely!
Do not damage the gasket!
Note
Unused terminals must remain open.

Control panel enclosure Conex®DIA-1
•Conex®DIA-1: for installation in the control
panel.
• Sensor interface: for installation near the sensors.
12.2 Power supply connection
1. Control panel enclosure: Plug the plug strip into
the corresponding terminal strip at the rear side of
the device. Ensure correct orientation.
2. Connect the protective earth conductor (PE) to
terminal 5 (wall-mounted enclosure) or terminal 8/
1 (control panel enclosure).
3. Connect the neutral conductor (N) (or the –
conductor with 24 V version) to terminal 3 (wall-
mounted enclosure) or terminal 8/2 (control panel
enclosure).
4. Connect phase (L1) (or the + conductor with 24 V
version) to terminal 1 (wall-mounted enclosure) or
8/3 (control panel enclosure).
Switch the device on and off by switching the power
supply on and off accordingly. The device itself is not
equipped with a separate on/off switch.
12.3 Relay outputs
With inductive loads (also relays and contactors),
interference suppression is necessary. If this is not
possible, protect the relay contacts using a
suppressor circuit as described below.
• With AC voltage:
• With DC voltage: Connect the free-wheeling
diode in parallel to relay or contactor.

final control elements used. Therefore
the connections described below
should only be considered as
guidelines.
