 | | LMG2...系列燃氣燃燒器控制器(SIEMENS) | | | LMG2...系列燃氣燃燒器控制器(SIEMENS) | | | | | | 產品介紹 | | Burner controls of the LMG... range are used for the startup and supervision of singleor 2-stage gas or gas / oil burners in intermittent operation. The flame is supervised with 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 startup ａnd 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 -
