KROM SCHRODER燃烧控制单元PFU760系列产品介绍
燃烧器控制单元PFU 760可控制，点燃和监视燃气燃烧器的间歇性或连续性。由于采用全电子设计，它们可以对各种工艺要求做出快速反应，因此也适合频繁的循环操作。
PFU 760可用于直接点火的工业燃烧器。
燃烧器可以是调节的或阶段控制的。
在工业炉上，PFU 760承担仅与燃烧器有关的任务，从而减轻了中央炉控制的负担，例如，它确保燃烧器在重新启动后始终在安全的状态下点燃。
燃烧器控制单元用于带有机械燃烧空气供应的燃烧器，其中风扇由单独的逻辑控制，用于大气燃烧器。
燃烧器控制单元PFU 760L上的空气阀控制可协助炉子控制冷却，吹扫和输出控制任务。
程序状态，设备参数和火焰信号水平可以直接从设备中读取。燃烧器可以手动控制，以进行调试和诊断。
如果燃烧器控制单元的本地要求发生变化，则可以使用光接口将PC软件BCSoft调整为应用程序的单元参数。
方便的输入和输出信号可视化系统以及错误历史记录为服务人员提供了支持。
为了减少安装和布线成本，ElsterKromschröder提供了现场总线接口PFA 700，以通过PROFIBUS-DP传输控制信号和反馈。
The burner control units PFU 760 control, ignite and monitor gas burners for intermittent or continuous operation. As a result of their fully electronic design they react quickly to various process requirements and are therefore also suitable for frequent cycling operation.
The PFU 760 can be used for directly ignited industrial burners.
The burners may be modulating or stage-controlled.
On industrial furnaces, the PFU 760 reduces the load on the central furnace control by taking over tasks that only relate to the burner, for example it ensures that the burner always ignites in a safe condition after it has been restarted.
The burner control unit is used for burners with mechanical combustion air supply where the fan is controlled by a separate logic and for atmospheric burners.
The air valve control on the burner control unit PFU 760L assists the furnace control for cooling, purging and output control tasks.
The program status, the unit parameters and the level of the flame signal can be read directly from the unit. The burner can be controlled manually for commissioning and diagnostic purposes.
If the local requirements on the burner control unit change, the PC software BCSoft can be adjusted to the unit parameters of the application by using the optical interface.
The service personnel is supported by a convenient visualization system of the input and output signals and the error history.
To reduce the installation and wiring costs, Elster Kromschröder offers the field bus interface PFA 700 to transfer the control signals and feedbacks via PROFIBUS-DP.
