燃烧机配件/西门子程序控制器LMG21.330B27、LMG22.330B27控制器

 产品介绍
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 ** by LEDs in the lockout reset button

Accurate program sequence owing to the digital processing of **s

LMG49... for atmospheric gas burners
