or occurrences that may arise during installation, use and mainte­nance of the device.

The operating company is responsible for the respect of the local
safety regulations including staff safety.

Risk of injury due to electrical voltage.

▶ Shut down the electrical power source of all the conductors and

isolate it before carrying out work on the system.

▶ If a 12...36 V DC or a 14...36 V DC powered version is installed

either in a wet environment or outdoors, all the electrical volt­ages must be of max. 35 V DC.

General information

nOTiCe

The device may be damaged by the fluid in contact with.

▶ Systematically check the chemical compatibility of the com-

ponent materials of the device and the fluids likely to come
into contact with the materials (for example: alcohols, strong
or concentrated acids, aldehydes, alkaline compounds, esters,
aliphatic compounds, ketones, halogenated aromatics or hydro­carbons, oxidants and chlorinated agents).

nOTiCe

Elements / Components sensitive to electrostatic discharges

▶ This device contains electronic components that are sensitive

to electrostatic discharges. They may be damaged if they are
touched by an electrostatically charged person or object. In the
worst case scenario, these components are instantly destroyed
or disabled as soon as they are activated.

▶ To minimise or even avoid any damage caused by an elec-

trostatic discharge, take all the precautions described in the
EN 61340-5-1 norm.

8 INSTALLATION

8.1 Safety instructions

Warning

Risk of injury due to non-conforming installation.

▶ The electrical and fluid installation can only be carried out by

qualified and skilled staff with the appropriate tools.

▶ Install appropriate safety devices (correctly rated fuse and/or

circuit-breaker).

▶ Respect the assembly instructions for the fitting used.

Risk of injury due to unintentional switch on of power supply
or uncontrolled restarting of the installation.

▶ Avoid unintentional activation of the installation.
▶ Guarantee a set or controlled restarting of the process subse-

quent to any intervention on the device.

8.2 Installation of the 8202 onto the pipe

Danger

Risk of injury due to high pressure in the installation.

▶ Stop the circulation of fluid, cut off the pressure and drain the

pipe before loosening the process connections.

Risk of injury due to the nature of the fluid.

▶ Respect the prevailing regulations on accident prevention and

safety relating to the use of dangerous fluids.

75°

Fig. 11: Angle to the vertical (8202)

→ Fit the fitting at an angle of ±75° max. to the vertical in order to

ensure the good operation of the pH/redox probe.

The pH or redox probe must always be immersed in the fluid
to prevent it drying out.

→ Once the device has been calibrated, remove the electronic

module from the sensor holder as shown Fig. 12.

→ Unscrew the nut between the electronic

module and the sensor holder.

8.4 Wiring

Danger

Risk of injury due to electrical voltage.

▶ Shut down the electrical power source of all the conductors and

isolate it before carrying out work on the system.

▶ If a 12...36 V DC or a 14...36 V DC powered version is installed

either in a wet environment or outdoors, all the electrical volt­ages must be of max. 35 V DC.

▶ All equipment connected to the device must be double insu-

lated with respect to the mains according to the standard
IEC 61010-1:2010.

▶ Observe all applicable accident protection and safety regula-

tions for electrical equipment.

• Use a high-quality electrical power supply (filtered

and regulated).

• Make sure the installation is equipotential (see
chap. 8.4.1).

8.4.1 Making the installation equipotential

To ensure the equipotentiality of the installation (power supply ­device - medium):

→ Connect together the various earth spots in the installation to

eliminate the potential differences that may occur between dif­ferent earthes.

→ Observe faultless grounding of the shield of the power supply

cable.

→ Special attention has to be paid if the device is installed on

plastic pipes because there is no direct earthing possible.
Proper earthing is performed by earthing together the metallic
devices such as pumps or valves, that are as close as possible
to the device.

Parameters menu,

• to read both the lowest and highest values of the chosen process

value, that have been measured by the device since the latest
reset (this feature is not active by default),

• to reset both the lowest and highest values of the chosen process

value, if the feature has been activated,

• to read the current values emitted on the 4...20 mA outputs.

• to get the state of the device and of the conductivity sensor with

the icons.
