PBS - Model APH - M(E) -Automatic Monoblock Gas Burner

The fundamental part of the automatics is a set of two one-chip microprocessors of the 8051 series, which substantially contributes to the safe operation of the whole unit by a mutual check on the algorithms of the burner’s operation. Replacement or reprogramming of the microprocessors allows the extension of the assortment of controlling algorithms of the automatics (e.g., continuous ventilation during pauses in operation, etc.). Communication of the automatics with the environment is possible manually by the operator or by a superior computer, or by remote control through RS-485 interface. Excluding basic functions, the standard automatics type is capable of the following:

• displaying information about the immediate operational state of the burner (ventilation, valve tightness control, ignition time, increase and decrease of output, etc.) by means of a two digit display and LED diodes
• displaying the reasons for the last 99 failures of the burner, which allows prompt and effective service
• displaying the ionic current level of the flame scanner
• closing the air intake line during each interrupted operation, which reduces flue gas loss caused by the flow of cold air through the consumer

The MA-3 automatics have an alpha-numeric display counter of operational hours, ventilation time which can be set, a special service regime, the possibility of a higher number of input and output signals.

The burners are a suitable source of heat for overpressure and underpressure consumers, especially for steam, hot water and warm water boilers. They can also be used for other consumers with an appropriate combustion chamber which will not stress the burner with external heat (e.g. air heaters, dryers, steam generators, exchangers, industrial and bakers’ furnaces and ovens, etc.). Using the burner for special technical purposes should be under advice from the manufacturer.
