FCU 500 Protective system controls FCU 500 Protective system control FCU 500 is designed to monitor and control central safety functions, e.g. gas min., gas max., air min., pre-purge, tightness test, high temperature operation or start enable for burner control units, in multiple burner systems on industrial furnaces. The FCU 500 controls multiple furnace zones acting as the central protective system control. If the centrally checked safety requirements, e.g. pre-purge, flow detector and pressure switch check, have been met, the FCU issues the start enable signal to the burner control units. The FCU is optionally available with integrated safety temperature monitor or safety temperature limiter, integrated tightness control and with an interface for controlling the capacity of actuators or a frequency converter interface. from the FCU via the optionally available optoadapter. Parameters can be changed and saved on the integrated parameter chip card. The parameter chip card can be removed easily, for example when the unit is replaced, and inserted into a new FCU to transfer the parameters. An integrated Manual mode allows the manual activation of the burner control units and adjustment of the butterfly valves. The fail-safe outputs for protecting the furnace, e.g. for fan, actuator and valves, are activated via a plug-in power module. When the maximum number of operating cycles has been reached, it can simply be replaced. The FCU can be installed on a DIN rail in the control cabinet. The plug-in connection terminal strips make it easier to install and remove the FCU. 120 V AC, -15/+10%, 50/60 Hz, ±5%, 230 V AC, -15/+10%, 50/60 Hz, ±5%.

BCU 370 Burner control units for single or forced draught burners BCU 370 Burner control unit BCU 370 controls, ignites and monitors industrial forced draught burners of unlimited capacity in intermittent or continuous operation. It can be used for directly ignited forced draught burners or forced draught burners ignited by a pilot burner. The BCU 370 activates the fan and sets the connected butterfly valve to pre-purge and ignition position. After pre-purge and burner start, the controller enable signal is issued to an external controller which positions the butterfly valve in accordance with the capacity demand. Post-purge occurs after the end of burner operation. The burner control unit BCU 370 monitors the gas and air pressure. An optionally integrated tightness control function checks the valves with an external gas pressure switch. Programmability by means of the optical interface and BCSoft PC software guarantees optimum adaptation to the relevant application. Adjustable start-up attempts and automatic restart which can be activated ensure the high flexibility of the burner equipment. The quick-start option allows standard-compliant start-up of the forced draught burner without pre-purge after a controlled shut-down. This avoids unnecessary admission of air into the combustion chamber. The heat output is available as quickly as possible after a temperature demand. from the unit. An integrated Manual mode allows manual start of the burner and setting of the butterfly valve position independently of the central control system. The BCSoft operatorcontrol and setting software provides a powerful tool for start-up and servicing. To reduce the installation and wiring costs, an optional PROFIBUS DP interface is available to transfer the activation signals and feedbacks. 120 V AC, -15/+10%, 50/60 Hz, BCU 570 BCU 570 Burner control unit BCU 570 controls, ignites and monitors industrial individual burners and forced draught burners of unlimited capacity in intermittent or continuous operation. It can be used for directly ignited burners or burners ignited by a pilot burner. The BCU 570 has an interface for control elements for burner capacity control. Both actuators (IC 20, IC 40, 3-point step and RBW) and frequency converters can be controlled. A valve proving system can be integrated as an option. The BCU 570 activates the fan and sets a connected actuator or frequency converter to pre-purge and ignition position. If the centrally checked safety requirements, e.g. pre-purge, flow detector and pressure switch check, have been met, the BCU 570 starts the burner. An enable signal is then issued to an external temperature controller which controls the actuator or frequency converter in accordance with the capacity demand. The burner control unit BCU 570 monitors the gas and air pressure. The optionally integrated valve proving system checks the valves by checking an external gas pressure switch or by checking whether the gas valve on the inlet side is closed. from the BCU via the optionally available optoadapter. All valid parameters are saved on the integrated parameter chip card. The parameter chip card can be removed easily, for example when the unit is replaced, and inserted into a new BCU to transfer the parameters. An integrated Manual mode allows the manual activation of the burner control units and adjustment of the butterfly valves. The fan output and the actuator and valve outputs which are checked for faults are accommodated in a plug-in power module. This can simply be replaced if necessary. The BCU can be installed on a DIN rail in the control cabinet.
