Basic safety information

Various dangerous situations

To avoid injury take care:

• not to use the device for the measurement of gas flow rates.

• not to use the device in explosive atmospheres.

• not to use the device in an environment incompatible with the
materials it is made of.

• not to subject the device to mechanical loads (e.g. by placing
objects on top of it or by using it as a step).

• not to make any external or internal modifications to the device.

• to prevent any unintentional power supply switch-on.

• to ensure that installation and maintenance work are
carried out by qualified, authorised personnel in possession of
the appropriate tools.

• to guarantee a defined or controlled restarting of the process,
after a power supply interruption.

• to use the device only if in perfect working order and in compli­ance with the instructions provided in the operating instructions.

• to observe the general technical rules when installing and using
the device.

note

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

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

note

Elements / Components sensitive to electrostatic discharges

• This device contains electronic components 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 go out of
order as soon as they are activated.

• To minimise or even avoid all damage due to an electrostatic
discharge, take all the precautions described in the EN 61340­5-1 and 5-2 norms.

7.3. Installation into the pipe of a
8045 with a G2'' nut

In order to ensure a high accuracy of the measurements and
good stability of the „flow zero“ point, install the device into
the processed medium at least 24 H before calibration.

→ Install the S020 fitting into the pipe taking into account the rec-

ommendations in chap. 7.2.

→ Check that there is a seal on the fitting and that it is not damaged.

Replace the seal if necessary.

→ Check that there is a seal (see mark 6, Fig. 8) on the flow sensor.
→ Insert the nut (see mark 3, Fig. 8) on the fitting.
→ Insert the snap ring (mark 2 Fig. 8) into the groove (mark 5 Fig.

8).

→ Position the arrow on the side of the device in the direction of the

flow: the totalizers will increment.

→ Insert the device (mark 1 Fig. 8) into the fitting.
→ Tighten the nut (mark 3, Fig. 8) by hand on the device.

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.

• Observe all applicable accident protection and safety regula­tions for electrical equipment.

• Use a high quality electrical power supply (filtered and
regulated).

• Make sure the installation is equipotential. See chap.

7.5.1.

• Use shielded cables with a temperature limit of 80 °C
minimum.

• Do not install the cables near high voltage or high fre­quency cables; If this cannot be avoided, observe a min.
distance of 30 cm.

• Protect the power supply by means of a 300 mA fuse and
a switch.

• Protect the relays by means of a max. 3 A fuse and a
circuit breaker (depending on the process).

• Do not apply both a dangerous voltage and a safety extra­low voltage to the relays.

Insert the supplied stopper gasket into the unused cable
gland to ensure the tightness of the device.

If two cables are used in the same cable gland, first insert
the supplied multi-way seal.

To wire the device:

→ Loosen the screw from the lid.
→ Flip the lid.
→ Loosen the 4 screws from the cover of the housing.
→ Remove the cover.
→ Loosen the nuts of the cable glands.
→ Insert the cable through the nut then through the cable gland.
→ Make sure the earth cable coming from the housing and, on a

version with stainless steel sensor, the cable coming from the
flow sensor, are connected as shown in Fig. 15, chap. 7.5.2.

→ Wire acc. to chap. 7.5.1 to 7.5.3.

7.5.1. Equipotentiality of the installation

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

→ Connect together the various earth spots in the installation to

eliminate the potential differences that may occur between dif­ferent earthes.

→ Observe faultless earthing of the shield of the power supply

cable, at both ends.

16

English

Type 8045

Installation and wiring

→ Connect the negative power supply terminal to the earth to sup-

press the effects of common mode currents. If this connection
cannot be made directly, a 100 nF/50 V capacitor can be fitted
between the negative power supply terminal and the earth.

→ 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
instruments such as pumps or valves, that are as close as pos­sible to the device. If no such instrument is near the device,
insert metallic earth rings inside the plastic pipes upstream and
downstream the device and connect these parts to the same
earth. The earth rings must be in contact with the fluid.

Danger due to non-conforming commissioning.

Nonconforming commissioning could lead to injuries and damage
the device and its surroundings.

• Before commissioning, make sure that the staff in charge
have read and fully understood the contents of the operating
instructions.

• In particular, observe the safety recommendations and intended use.

• The device / the installation must only be commissioned by suit­ably trained staff.

• Before commissioning the device, enter the K factor of the fit­ting used. See chap. 8.6.
