Air/gas ratio control on melting furnace for ensuring stoichiometric combustion over the entire capacity range.

Air/gas ratio control, Class A, for maintaining a constant air/gas pressure ratio for modu - lating-controlled burners or with VAS
1 bypass valve for stage-controlled burners. Pressure preset by the air control line. The VAG..N can also be used as a zero gov
-ernor for gas engines
 

 

Function
The regulator is closed when it is disconnected from the power supply. Opening: Connect the system to the electrical power supply (alternating voltage will be rectified). The blue LED lights up. The coil's magnetic field pulls the armature upwards and clears the supply nozzle for the gas inlet pressure pe. The gas passes through the internal impulse tube to the adjustment diaphragm and then pushes the valve disc open. The outlet pressure is applied to the servo diaphragm via the internal bypass.

The servo regulator then maintains a set constant outlet pressure pG.

WARNING

1,Do not install it in the following places
(1)Places where special drugs or corrosive gases are present (e.g. ammonia, sulfur, hydrochloric acid, ethylene compounds, etc.)
(2)Places where water drops or is too wet.
(3) High temperature places.
(4) A place where the vibration lasts for a long time.
2, Please connect according to the specified basis.
3, In order to prevent electric shock and meter damage, please connect the power supply last. Misunderstanding that touching other subterminals can cause accidents and damage to the meter.
4,The load of each terminal connection should not exceed the rated value.
5,Please use the power supply with the same voltage and frequency as indicated by the machine.
6,For timers and auxiliary relays used as additional functions, please select reliable products and correctly form loops according to your needs.
7,Please ground according to the standard above D type grounding specified in the electrical equipment technical standard, and be sure to ground the burner body.
8,Do not tie the power cord and the high-voltage cable of the ignition transformer with the wire of the flame monitoring rod, and do not put it in the same wire tube, please wire separately.In particular, the high-voltage cable should be distributed separately, 10 cm away from the burner controller Above.
9,Please connect the ignition transformer high-voltage cable reliably to ensure that there is no bad contact. Poor contact will produce high frequency waves, radio noise, etc., causing misoperation. In addition, install the ignition transformer directly with the burner body or the metal part electrically connected to the burner body.
10,After connecting cables, ensure that the cables are correctly connected. Incorrect wiring may damage the unit or cause incorrect actions.
