The new electrical cabinet for large burners is very friendly for the user. 

It has a Text Display placed up to 10m from the burner, where all the status, alarms, and some maintenance information is displayed in two languages (also with different characters). 

All the inputs and outputs of the burner cabinet can be seeing in a programmable relay (Logo from Siemens). Additional status and alarms from the burner are also displayed by the burner controller (MPI from Brahma). All this together allow for an instant assistance to the local service from factory.
