MADAS手動(dòng)復(fù)位電磁閥
馬達(dá)斯MADAS氣體手動(dòng)復(fù)位電磁閥,可用于常開和常閉。
常開:
它關(guān)閉從氣體檢測(cè)器接收信號(hào),只能在建立后重新設(shè)置,并避免導(dǎo)致氣體檢測(cè)器干擾的泄漏。
重要事項(xiàng):必須連接到氣體檢測(cè)器,而不是連續(xù)地產(chǎn)生脈沖信號(hào)。
常閉:
只有當(dāng)電磁閥的電連接器上的LED始終打開時(shí),才被視為安全裝置。
它無張力(黑色)閉合或從氣體檢測(cè)器接收信號(hào)。
如果關(guān)閉是由于斷電導(dǎo)致的,電磁閥可以重新設(shè)置為使用國(guó)內(nèi)用戶(例如爐子)。
在這種情況下,您沒有處于安全狀態(tài),但是當(dāng)張力回升時(shí),電磁閥關(guān)閉并準(zhǔn)備好復(fù)位并進(jìn)行安全裝置的功能。
如果關(guān)閉是由于氣體檢測(cè)器信號(hào),則電磁閥只能在建立后被復(fù)位,并排除導(dǎo)致氣體檢測(cè)器干預(yù)的泄漏。
只需為線圈供電就不會(huì)打開閥門。復(fù)位機(jī)構(gòu)必須手動(dòng)操作(參見手動(dòng)復(fù)位)。

Gas manual reset solenoid valve that can be used both as normally open and as normally closed.
Normally open:
It closes receiving the signal from gas detector and can be reset only after founded and escluded the leakage that caused the gas detector intervention.
IMPORTANT: it must be connected to a gas detector that gives impulse signal, not continuously.
Normally closed:
It must be considered safety device only when the led on the electric connector of the solenoid valve is always on.
It closes without tension (black-out) or receiving the signal from gas detector.
If the closing is due to black-out the solenoid valve can be however reset to use domestic users (for example stoves).
In this case you are not in safety condition but when tension comes back the solenoid valve closes and it is ready to be reset and to do the safety device function.
If the closing is due to a gas detector signal the solenoid valve can be reset only after founded and escluded the leakage that caused the gas detector intervention.
Simply powering the coil does not open the valve. The reset mechanism has to be operated by hand (see MANUAL RESET).
