Dungs LGW 50 A2P Pressure Switch with Test Button
The LGW 50 A2P is an adjustable differential pressure switch as per EN 1854 designed for automatic burner controls.
Suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value. The reference value (switching point) is adjusted on a setting wheel provided with a scale.
Suitable for air, flue and exhaust gases and other non-aggressive gases as differential pressure switches; not suitable for industrial combustion gases.
Test Button
The LGW10A2P differential pressure switch is equipped with a test button. The test button allows for a service friendly check of the safety function. If the test key is pressed while the pressure exists, the connection to the pressure connection G 1/4 is interrupted and the pressure under the diaphragm is released. The microswitch of the pressure switch changes the contact position from NO to NC.
If the test button is released, the pressure below the diaphragms is built up again and the microswitch changes to its original position.
Switching function
As pressure rises: 1 NC opens, 2 NO closes
As pressure falls: 1 NC closes, 2 NO opens
