Description

Burner control units BCU 560 or BCU 565 control, ignite and monitor gas burners in intermittent or continuous operation. They can be used for directly ignited industrial burners of unlimited capacity. The burners may be modulating-controlled or stage-controlled. Their fast reaction to various process requirements makes the BCUs suitable for frequent cycling operation.

On industrial furnaces, they reduce the load on the central furnace control by taking over tasks that relate to the burner, for example they ensure that the burner ignites in a safe condition when it is restarted.

The air control on the BCU..F1, F2 or F3 assists the furnace control for cooling, purging and capacity control tasks.

The burner control units have an interface via which an air valve or actuator (IC 20, IC 40 or RBW) can be controlled for staged or modulating burner capacity control.

The program status, the unit parameters and the level of the flame signal can be read directly from the unit. The burner or a connected control element can be activated manually using the integrated Manual mode for setting and diagnostic purposes. Thanks to the optionally integrated valve proving system, the valves can be checked for leaks by querying an external gas pressure switch or it can be checked whether the gas valve on the inlet side is closed.

Using the BCSoft program, the parameters, analysis and diagnostic information can be read from a BCU via the optionally available opto-adapter. All valid parameters are saved on an integrated parameter chip card. The parameter chip card can be removed from the old unit and inserted into a new BCU to transfer the parameters, for example when replacing the unit.
