| 产品介绍 |
Burner controls of the LMG... range are used for the startup and supervision of singleor2-stage gas or gas / oil burners in intermittent operation. The flame is supervisedwith an ionisation probe or 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, using the adapters, burner controls LFI7... and LFM1...(refer to Ordering). Detection of undervoltages Air pressure supervision with functional test of air pressure monitor during startupand operation Electrical remote reset Display of error code and flame signal by LEDs in the lockout reset button Accurate program sequence owing to the digital processing of signals LMG49... for atmospheric gas burners
