Features At a Glance
 

LMG... are designed for the startup and supervision of 1- or 2-stage gas or forced draft gas / oil burners in intermittent operation. The flame is supervised with an ionization probe or a UV flame detector QRA…. (with ancillary unit AGQ2 …A27). LMG21... / LMG22... in the same housing replace burner controls LGB21... / LGB22... (refer to «Type summary») and - with the help of the relevant adapters - burner controls LFI7... and LFM1... (refer to «Ordering»).

- Detection of undervoltages
- Air pressure supervision with functional check of the air pressure switch during startup and operation (only LMG2...)
- Electrical remote reset
- Display of error code and flame signal by signal lamps in the lockout reset button
- Accurate control sequence thanks to digital signal processing

 

 

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.
