Technical descriptionThe pressure switch GW…A6 and the double pressure switch GW… /.…A6 are adjustable compact pressure switches as per EN for firing systems.They are suited for switching a circuit on, off or over if the actual pressure value changes compared to the set-point.The setpoint (switching point) is set on an adjusting wheel with scale. A test nipple is integrated in the metal housing as standard.

ApplicationPressure monitoring in combustion, ventilation and air-conditioning tech-nologies.Suitable for gases of families 1,2,3 and other neutral gaseous media.

ApprovalsEC type test approval as per EC Gas Appliance Directive:

GW...A6 CE-0085 AO 3220

EC type test approval as per EC Pres-sure Appliance Directive:

GW...A6 CE0036

Pressure switch class „S“ as per EN 1854.

Functional descriptionSingle-acting pressure switch in over-pressure range.The pressure switches operate without any power supply.

Switching responseGW…A6Short response time during pressure fluctuations.

GW…A6/1Slow response time during short-term pressure fluctuations by additional damping nozzle.

GW…A6 pressure switchThe control unit responds to pressure. If the setpoint is exceeded or undershot, the circuit is switched on, off or over.

GW… / …A6 double pressure switchCombination of two flanged GW...A6 single pressure switches. The two setpoints are set separately and inde-pendently. A combination of different setpoint ranges is therefore possible. The two control units are fed from the same medium at the medium’s pres-sure.

Definition of ∆p switching differ-enceThe ∆p switching difference is the pressure difference between the up-per and lower switching pressure.

Switching function

If pressure increases:1 NC opens, 2 NO closes.If pressure drops:1 NC closes, 2 NO opens.

Zur Erhöhung der Schaltleistung wird bei DC-Anwendungen < 20 mA und 24 V der Einsatz eines RC-Gliedes empfohlen.

To increase the switching capac-ity, we recommend that you use a RC device for current values < 20 mA and 24 V d.c. applica-tions.

Pour augmenter la puissance de rupture, l'utilisation d'un circuit RC est préconisée pour les applications à courant continu < 20 mA et 24 V.

Rohrleitungsdichtheits-prüfung: Kugelhahn vor dem Druckwächter schlie-ßen.

Nach Abschluß von Ar-beiten am Druckwäch-ter: Dichtheitskontrolle und Funktionskontrolle durchführen.

Niemals Arbeiten durch-führen, wenn Gasdruck oder Spannung anliegt. Offenes Feuer vermeiden. Örtliche Vorschriften be-achten.

Bei Nichtbeachtung der Hinweise sind Personen- oder Sachfolgeschäden denkbar.

Pipeline leakage test: clo-se ball valve upstream of the pressure switch.

On completion of work on the pressure switch, perform a leakage and function test.

Never perform work if gas pressure or power is applied. No naked flame. Observe local regula-tions.

If these instructions are not heeded, the result may be personal injury or damage to property.

En cas de non-respect de ces instructions, des dommages corporels ou matériels sont possible.

Ne jamais effectuer des travaux sous pression et sous tension. Eviter toute flamme ouverte. Observer les réglementations.

Une fois les travaux sur le pressostat terminés, procéder toujours à un contrôle d´étanchéité et de fonctionnement.

Contrôle de l´étanchéité de la conduite: fermer le robinet à boisseau sphèrique avant le pres-sostat.

Per la prova di tenuta delle tubature: chiudere il rubinetto a sfera davanti al corpo pressostato.

Al termine dei lavori effet-tuati su un pressostato: predisporre un controllo sia della tenuta che del funzionamento.

In nessun caso si deb-bono effettuare lavori in presenza di pressione gas o di tensione elettrica. Evitare i fuochi aperti e osservare le prescrizioni pubbliche.La non osservanza di quanto suddetto può im-plicare danni a persone o cose.

Kondensat darf nicht in das Gerät gelangen. Bei Minustemperaturen, durch Vereisung Fehl-funktion/Ausfall mög-lich.

Eviter l'entrée de conden-sats dans le pressostat, une prise en glace par température négative nuirait à son fonctionne-ment.

Do not allow condensate to flow into the equip-ment. In case of subzero temperatures, malfunc-tion or equipment failure may be possible due to icing.

Nell' apparecchio non deve infiltrarsi alcuna condensa. Alle tempera-ture negative sarebbe-ro possibili disfunzioni dovute a formazione di ghiaccio.

Arbeiten am Druckwäch-ter dürfen nur von Fach-personal durchgeführt werden.

Seul du personnel spécia-lisé peut effectuer des tra-vaux sur le pressostat.

Work on the pressure switch may only be perfor-med by specialist staff.

Qualsiasi operazione ef-fettuata sul pressostato deve essere fatta da par-te di personale compe-tente.

Die Druckgeräterichtlinie (PED) und die Richtlinie über die Gesamtener-gieeffizienz von Gebäu-den (EPBD) fordern eine regelmässige Überprüfung von Heizungsanlagen zur langfristigen Sicherstel-lung von hohen Nutzungs-graden und somit gering-ster Umweltbelastung. Es besteht die Notwendig-keit sicherheitsrelevante Komponenten nach Er-reichen ihrer Nutzungs-dauer auszutauschen. Diese Empfehlung gilt nur für Heizungsanla-gen und nicht für Ther-mprozessanwendungen. DUNGS empfiehlt den Austausch gemäss fol-gender Tabelle:

The Pressure Equipment Directive (PED) and the Energy Performance of Buildings Directive (EPBD) require a periodic inspec-tion of heating applianc-es in order to ensure a high degree of efficiency over a long term and, consequent-ly, the least environmental pollution. It is necessary to replace safety-rele-vant components after they have reached the end of their useful life. This recommendation applies only to heating appliances and not to industrial heating proc-esses. DUNGS recom-mends replacing such components according to the following table:

La directive concernant les chauffe-bains à pression (PED) et la directive sur la performance énergétique des bâtiments (EPBD) exigent une vérification régulière des installations de chauffage, afin de garantir à long terme des taux d‘utilisation éle-vés et par conséquent une charge environnementale minimum. Il est nécessaire de remplacer les compo-sants relatifs à la sécurité lorsqu‘ils ont atteint la fin de leur vie utile. Cette re-commandation ne s‘appli-que qu‘aux installations de chauffage et non aux applications de processus thermique. DUNGS recom-mande le remplacement, conformément au tableau qui suit :

La direttiva per apparecchi a pressione (PED) e la direttiva per l‘efficienza dell‘energia totale per edifici (EPBD), esi-gono il controllo regolare degli impianti di riscaldamento per la garanzia a lungo termine di un alto grado di rendimento e con ciò di basso inquinamen-to ambientale. Ciò rende necessaria la sostituzione di componenti rilevanti dal punto di vista della sicu-rezza alla scadenza della loro durata di utilizzazione. Questo suggerimento vale solo per impianti di riscal-damento e non per impie-ghi per processi termici. DUNGS consiglia detta sostituzione in conformità alla sottostante tabella:
