Intended Use
2. INTENDED USE
WARNING!
Incorrect use of the coil AC19 can be dangerous to people,
nearby equipment and the environment.
• The solenoid coil AC19 is used to actuate valves which control
gaseous or liquid media. It was designed for use in explosion
group II, category 2D, Ex mbD, IP64, T130°C and in explosion
group II, category 2G and temperature class T4 (see specifica-
tions on the - approval plate).
• The coil AC19 is always attached to the core feed pipe of the
valve fitting and secured with a nut. In this way coil and valve
body are connected in such a way that a closed system is for-
med which may also be used as a category 2 device to control
petrol in petrol pumps. For this application a valve body made of
metal (brass, aluminium or stainless steel) must be used.
When using the device, observe the permitted data, operating
conditions and application conditions which
– are specified in the operating instructions for the solenoid coil
AC19, on the rating plate, in the contract documents
– as well as in the operating instructions for the solenoid valve
actuated with the coil.
The coil may be used only in conjunction with third-party devices
and components recommended and authorised by Bürkert.
Correct transportation, correct storage and installation and careful
use and maintenance are essential for reliable and problem-free
operation.
• Any other use is considered improper use.Bürkert is not liable
for any resulting damage. The user alone bears the risk.
• Use the device only as intended.
2.1. Restrictions
If exporting the system/device, observe any existing restrictions.
2.1.1. Explosion protection approval
The explosion protection approval is only valid if you use the modules
and components authorised by Bürkert, as described in these ope-
rating instructions.
The coil AC19 may be used only in combination with the valve types
released by Bürkert, otherwise the explosion protection approval will
be terminated!
If you make unauthorised changes to the system, the modules or com-
ponents, the explosion protection approval will be terminated.

Following installation, solenoid coil and valve body form a closed
system. If used in the EX area, there is a danger of explosion if the
system is opened during operation!
• The system must not be disassembled during operation.
Danger of explosion caused by electrostatic charge!
If there is a sudden discharge from electrostatically charged devices
or persons, there is a danger of explosion in the EX area.
• Take appropriate measures to prevent electrostatic charges in the
EX area.
• Clean the device surface of the solenoid valve by gently wiping
it with a damp cloth
DANGER!

There is a serious risk of injury when reaching into the equipment.
• Only trained electrical engineers may work on the electrical
system.
• Before starting work, always switch off the power supply and
safeguard to prevent re-activation!
• Observe applicable accident prevention and safety regulations
for electrical equipment!
Danger of burns/danger of fire during long-term operation!
The solenoid coil may become very hot during long-term operation.
• Take hold of a device which has been running for a prolonged
period with protective gloves only.
Danger – high pressure!
There is a serious risk of injury when reaching into the system.
• Only skilled and instructed personnel may work on the system
with suitable tools.
• Before disconnecting lines and valves, switch off the pressure
and bleed the lines.
• During installation note the direction of flow.
• Observe applicable accident prevention and safety regulations
for pressurised devices!
• After an interruption in the power supply or fluid supply, ensure
that the process is restarted in a defined or controlled manner!

5. APPLICATION CONDITIONS
5.1. Special conditions
5.1.1. Short-circuit protection
To protect each solenoid against short-circuit, a fuse (max. 3 x Ib in
accordance with IEC 60127-2-1), corresponding to the rated current,
or a motor protection switch with short-circuit and thermal quick release
(set to rated current) must be connected upstream.
• At very low rated currents of the solenoid the fuse with the lowest
current value is adequate according to the stated IEC standard.
This fuse may be housed in the associated supply unit or must be
connected separately upstream.
• The fuse rated voltage must be the same or higher than the indicated
nominal voltage of the solenoid.
• The interruption rating of the fuse link must be the same or higher than
the maximum short-circuit current to be accepted at the installation
site (usually 1500 A).

Bestimmungsgemässe Verwendung
2. BESTIMMUNGSGEMÄSSE
VERWENDUNG
WARNUNG!
Bei nicht bestimmungsgemäßem Einsatz der Spule AC19
können Gefahren für Personen, Anlagen in der Umgebung
und die Umwelt entstehen.
• Die Magnetspule AC19 dient zum Betätigen von Ventilen welche
gasförmige oder flüssige Medien steuern.
Sie wurde für den Einsatz in in Explosionsgruppe II, Kategorie D,
EX mbD, IP64, T130° und Explosionsgruppe II, Kategorie 2G
und Temperaturklasse T4 konzipiert (siehe Angaben auf dem
- Zulassungsschild).
• Die Spule AC19 wird immer auf das Kernführungsrohr der Ven-
tilarmatur montiert und mittels einer Mutter befestigt. Auf diese
Weise werden Spule und Ventilkörper so verbunden, dass
ein geschlossenes System entsteht, das auch in Tanksäulen
zur Steuerung von Benzin als Kategorie -2- Gerät eingesetzt
werden darf. Für diesen Einsatzzweck muss ein Ventilkörper aus
Metall (Messing, Aluminium oder Edelstahl) verwendet werden.
Für den Einsatz sind die zulässigen Daten, Betriebs- und Einsatz-
bedingungen zu beachten, die
– in der Bedienungsanleitung für die Magnetspule AC19, auf dem
Typschild, in den Vertragsdokumenten
– sowie in der Bedienungsanleitung für das mit der Spule
betätigte Magnetventil
spezifiziert sind.
Eine andere oder darüber hinausgehende Benutzung gilt als nicht
bestimmungsgemäß.
Für hieraus resultierende Schäden haftet Bürkert nicht.
Das Risiko trägt allein der Anwender.
• Setzen Sie das Gerät nur bestimmungsgemäß ein.
Die Spule darf nur in Verbindung mit von Bürkert empfohlenen
bzw. zugelassenen Fremdgeräten und -komponenten eingesetzt
werden.
Voraussetzungen für den sicheren und einwandfreien Betrieb sind
sachgemäßer Transport, sachgemäße Lagerung und Installation
sowie sorgfältige Bedienung und Instandhaltung.
2.1. Beschränkungen
Beachten Sie bei der Ausfuhr des Systems/Gerätes gegebenenfalls
bestehende Beschränkungen.
2.1.1. Ex-Zulassung
Die EX-Zulassung ist nur gültig, wenn Sie die von Bürkert zugelassenen
Module und Komponenten so verwenden, wie es in dieser Bedienungs-
anleitung beschrieben ist.
Die Spule AC19 dürfen Sie nur in Kombination mit den von Bürkert frei-
gegebenen Ventiltypen einsetzen, andernfalls erlischt die Ex-Zulassung!
Nehmen Sie unzulässige Veränderungen am System, den Modulen
oder Komponenten vor, erlischt die Ex-Zulassung ebenfalls.

nung ab und sichern Sie diese vor Wiedereinschalten!
• Beachten Sie die geltenden Unfallverhütungs- und Sicherheits-
bestimmungen für elektrische Geräte!
Verbrennungsgefahr/Brandgefahr bei Dauerbetrieb!
Die Magnetspule kann im Dauerbetrieb sehr heiß werden.
• Fassen Sie ein Gerät das bereits länger in Betrieb ist nur mit
Schutzhandschuhen an.
Gefahr durch hohen Druck!
Bei Eingriffen in das System besteht akute Verletzungsgefahr.
• Arbeiten am System dürfen nur durch fachkundiges und unter-
wiesenes Personal mit geeignetem Werkzeug durchgeführt
werden.
• Schalten Sie vor dem Lösen von Leitungen und Ventilen den
Druck ab und entlüften Sie die Leitungen.
