Abstract

An apparatus for monitoring the safe operation of a domestic gas-fired water heater has a gas leak detector which operates on changes in its electrical resistance in the presence of gas such as to successively energise a row of LEDs as the gas concentration increases up to a threshold level which precipitates a system trip/lock-out, a flashing LED warning and which requires manual resetting. A self-checking circuit design ensures separate flashing LED indication in the event of sensor power supply or output signal cable failure and a manual/auto changeover switch on the LED indicator unit permits temporary unmonitored operation during emergencies.

Description

MontageAssembly

Das Gerät wird neben dem Not-Aus-Schalter außerhalb vom Kessel­ raum montiert. Der Gassensor wird über dem Brenner an der Decke im Kesselraum angebracht.The device is located next to the emergency stop switch outside the boiler room mounted. The gas sensor is on the burner on the ceiling installed in the boiler room.

FunktionsbeschreibungFunctional description

Bei einer Gasleckage wird die ausgetretene Gaskonzentration durch Leuchtdioden angezeigt. Übersteigt das ausgetretene Gas eine be­ stimmte Menge, wird die komplette Kesselanlage abgeschaltet. Die Störung wird durch eine Blinkdiode angezeigt.In the event of a gas leak, the gas concentration escapes through LEDs are displayed. If the leaked gas exceeds a be the correct amount, the entire boiler system is switched off. The fault is indicated by a blinking diode.

Das Gerät überwacht sich selbst.The device monitors itself.

Störung beim Sensorfühler, Sensorheizung oder Kabelbruch, wird ebenfalls durch Blinkdioden angezeigt.Fault in the sensor sensor, sensor heating or cable break also indicated by blinking diodes.

Störungen sind:
1. Sensorfühler defekt,
2. Sensorheizung defekt,
3. Kabelbruch,
4. Gasleckage.Disorders are:
1. Sensor sensor defective,
2. Sensor heating defective,
3rd cable break,
4. Gas leakage.

Bei jeder Störung muß das Gerät wieder neu entriegelt werden. Das Gerät kann auf Hand und Automatik betrieben werden. Grüne Leuchtdiode bedeutet: Gerät in Betrieb.In the event of any malfunction, the device must be unlocked again. The device can be operated manually and automatically. Green LED means: device in operation.

Da sich das Gerät selbst überwacht und jede Störung sofort an­ zeigt, kann sich der Kunde ganz auf die Funktion des Gerätes ver­ lassen. Auch die kleinste Gasmenge bei einer Leckage, wird durch Leuchtdioden angezeigt. Der Kunde hat dadurch die Chance noch be­ vor die Anlage auf Störung geht, diese überprüfen zu lassen.Because the device monitors itself and any malfunction immediately shows, the customer can completely ver on the function of the device to let. Even the smallest amount of gas in the event of a leak is detected by LEDs are displayed. The customer still has the chance Before the system goes into trouble, have it checked.

Trotz meinen Nachforschungen konnte ich kein Leckgas-Überwachungs­ system finden, das irgendwie mit meinem identisch wäre, oder die gleichen Funktionen besitzt.Despite my research, I was unable to monitor the leakage gas find a system that would be somehow identical to mine, or the has the same functions.

Das Gerät überwacht den Heizraum, um bei Gasausbruch die kom­ plette Heizungsanlage abzuschalten. Das Gerät kann bei allen Heizungsanlagen die Erdgas verbrennen, eingesetzt werden, dadurch gekennzeichnet, daß die ausgetretene Gasmenge durch Leuchtdioden angezeigt wird. Übersteigt das ausgetretene Gas eine bestimmte Konzentration im Heizraum, wird die Heizungs­ anlage abgeschaltet.
Das Gerät überwacht sich selbst. Störungen beim Gassensor, Sensorheizung oder Kabelbruch wird durch Blinkdioden angezeigt. Bei jeder Gasstörung muß das Gerät wieder von Hand entriegelt werden.The device monitors the boiler room to switch off the entire heating system in the event of a gas outbreak. The device can be used in all heating systems that burn natural gas, characterized in that the amount of gas escaping is indicated by LEDs. If the leaked gas exceeds a certain concentration in the boiler room, the heating system is switched off.
The device monitors itself. Malfunctions in the gas sensor, sensor heating or cable break are indicated by blinking diodes. The device must be unlocked manually in the event of any gas fault.
