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.

Insert the supplied stopper gaskets into the unused cable glands of a wall-mounted version to ensure the tightness of the device.

Only move the selectors when the power supply is off.

• Use a filtered and regulated 12-36 V DC power supply.

• Make sure the installation is equipotential. See chap. “7.4.1”.

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

• Protect the power supply of each transistor output by means of a 125 mA fuse.

• 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 extra-low voltage to the relays.

7.4.1 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. → Connect the negative power supply terminal to the earth to suppress 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 earthing 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.

8.6.2 Choosing the flow rate units, the number of decimals and the units of the totalizers

When the flow rate unit has been changed:

• Manually reset both totalizers.

• Manually convert the flow rate values in the different settings.

• If, furthermore, the unit changes from "metric" to "gallon" and vice versa, convert the K factor using following formulae:

- K factor in pulse/US Gallon = K factor in pulse/l x 3,785

- K factor in pulse/IMP Gallon = K factor in pulse/l x 4,546

The max. flow rate that can be displayed depends on the number of decimals chosen:

• 9999 if the number of decimals = 0 or AUTO,

• 999,9 if the number of decimals = 1,

• 99,99 if the number of decimals = 2,

• 9,999 if the number of decimals = 3.

• If the units chosen for the totalizers is "millilitre", the totalizer values are displayed in litres followed by three decimals.

• If the units chosen for the totalizers is "litre", the totalizer values are displayed in litres without decimals.

The "UNIT" parameter makes it possible to choose:

• the flow rate units.

• a fixed number of decimals (choose 0, 1, 2 or 3) to display the flow rate in the Process level, or a floating decimal point (choose "AUTO"): the device automatically adjusts the position of the decimal point depending on the chosen unit and the measured flow rate.

• the volume units of the totalizers if the unit previously chosen is in litres, in millilitres or in m

. The totalizer values

are automatically displayed in gallons if the flow rate unit chosen is in gallons.

This parameter makes it possible to dampen the fluctuations:

Ten filters are available.

When the "fast" filter is active and the flow rate varies for ±30 % (for example when charging the pipe or stopping the flow), the filter is disabled: the new flow rate is immediately taken into account by the device.

If a too high filter is chosen, the device does not detect the sudden flow rate changes thus the flow rate in the pipe may strongly defer from the displayed flow rate or the flow rate transmitted to the current output.

A sudden stop of the flow is immediately detected whatever filter is active.

5 BESCHREIBUNG

5.1 Vorgesehener Einsatzbereich

Der Transmitter Typ 8025 Universal kann an einen abgesetzten Durchfluss-Sensor, der ein Frequenzsignal ausgibt, angeschlossen werden. Die vorgeschriebenen technischen Daten des angeschlossenen DurchflussSensors sind im Kapitel 6 beschrieben.

Wenn das Gerät an einem Durchfluss-Sensor angeschlossen ist, ermöglichen die einstellbaren Transistor- und, bei einigen Ausführungen, die beiden Relaisausgänge dem Gerät, ein Magnetventil zu schalten, einen Alarm zu aktivieren oder eine dem Durchfluss proportionale Frequenz zu erzeugen, und der 4-20 mA Stromausgang ermöglicht einen Regelkreis aufzubauen.

5.2 Allgemeine Beschreibung

Der 8025 Universal ist ein Durchfluss-Transmitter mit Display und ist in Wandmontage- oder Schaltschrank-Ausführung erhältlich :

• Die Schaltschrank-Ausführung besteht aus einem Elektronikmodul, integriert in einem offenen Gehäuse mit Display.

• Die Wandmontage-Ausführung besteht aus einem Elektronikmodul, integriert in einem Gehäuse mit Deckel, Display und 3 Kabelverschraubungen.

Das Gerät verfügt über einen 4-20 mA Stromausgang (Analogausgang, AO1), einen Transistorausgang (Grundeinstellung: Pulsausgang, DO1) und zwei Mengenzähler.

Einige Ausführungen sind auch mit zwei Relaisausgängen (mit DO2 und DO3 gekennzeichnet) versehen.

Das Gerät funktioniert als 3-Leiter-System und benötigt eine Betriebsspannung von 12-36 V DC oder 115/230 V AC.

Der elektrische Anschluss erfolgt über die Klemmenleisten der Elektronikplatine.

Installation und Verkabelung

7.4 Verkabelung

Gefahr!

Verletzungsgefahr durch Stromschlag!

▶ Schalten Sie vor Beginn der Arbeiten in jedem Fall alle existierenden am Gerät angeschlossenen Spannungs-

Versorgungen ab, und sichern Sie diese vor unbeabsichtigtem Wiedereinschalten!

▶ Beachten Sie geltende Unfallverhütungs- und Sicherheitsbestimmungen für elektrische Geräte!

Bei einer Wandmontage-Ausführung in die nicht verwendeten Kabelverschraubungen die mitgelieferten Stopfen einfügen, um die Dichtheit des Gerätes zu gewährleisten.

Die Auswahlschalter nur spannungsfrei einstellen.

• Eine gefilterte und geregelte 12-36 V DC-Versorgungsspannung verwenden.

• Den Potentialausgleich der Installation gewährleisten. Siehe Kap. “7.4.1”.

• Abgeschirmte Kabel mit einer Betriebsgrenztemperatur höher als 80 °C verwenden.

• Die Verlegung des Kabels in der Nähe von Hochspannungs- oder Hochfrequenzkabeln vermeiden; Wenn eine benachbarte Verlegung unvermeidlich ist, einen Mindestabstand von 30 cm einhalten.

• Die Stromversorgung des Gerätes mit einer 300 mA-Sicherung und einem Schutzschalter absichern.

• Die Stromversorgung jedes Transistorausgangs mit einer 125 mA-Sicherung absichern.

• Das Relais mit einer 3A-Sicherung (max.) und einem Sicherungsautomat (für den Prozess geeignet) schützen.

• Nicht gleichzeitig eine gefährliche Spannung und eine Schutzkleinspannung an die Relais anschließen.

7.4.1 Potentialausgleich der Installation gewährleisten

Um die Äquipotentialität der Installation (Versorgungsspannung - Gerät - Flüssigkeit) zu gewährleisten,

→ Die verschiedenen Erdungspunkte der Installation aneinander anschließen, damit die zwischen zwei Erdungs-

punkten möglicherweise erzeugten Potentialdifferenzen beseitigt werden.

→ Auf vorschriftsmäßige Erdung der Abschirmung des Versorgungskabels an beiden Enden achten. → Den Minuspol der Stromversorgung an die Erde anschließen, um die Auswirkungen von Gleichtaktströmen

zu unterdrücken. Wenn die Verbindung nicht direkt vorgenommen werden kann, kann ein Kondensator mit 100 nF/50 V zwischen Minuspol der Stromversorgung und Erde geschaltet werden.

→ Geben Sie darauf besonders acht, wenn das Gerät auf Kunststoffrohren installiert wird, weil keine direkte

Erdung möglich ist. Zur ordnungsgemäßen Erdung alle die sich in der Nähe des Geräts befindenden metallischen Instrumente, wie Ventile oder Pumpen, an den selben Erdungspunkt anschließen. Sind keine solchen Instrumente in der Nähe des Gerätes eingebaut, Stromauf- und –abwärts des Gerätes Erdungsringe in die Kunststoffrohre einführen und diese mit derselben Erde verbinden. Die Erdungsringe müssen in Kontakt mit der Flüssigkeit sein.
