IFD 450 Immediate fault lock-out following flame failure during operation. IFD 454 Automatic restart following flame failure during operation. Automatic burner control units for continuous operation IFD 450, IFD 454 IFD 450, IFD 454 The automatic burner control units for continuous operation IFD 450, IFD 454 ignite and monitor gas burners. As a result of their fully electronic design they react quickly to various process requirements and are therefore also suitable for frequent cycling operation. They can be used for directly ignited industrial burners of unlimited capacity. The burners may...

Application > Application examples 1.1 Application examples 1.1.1 Two-stage-controlled burner Control: ON/OFF or ON/HIGH/LOW/OFF The burner BIO/BIC starts at low-fire rate. Once the normal operating state is reached, the automatic burner control unit for continuous operation IFD 454 or IFD 450 will release control. The PLC can now pulse the air solenoid valve VR..R in order to control the capacity between high and low fire.

Application > Application examples 1.1.2 Modulating-controlled burner Control: ON/OFF/continuous The PLC uses the actuator IC 20 to move the air butterfly valve BVA to ignition position. The burner BIO/BIC starts at low-fire rate. Once the normal operating state is reached, the PLC uses the actuator IC 20 and the air butterfly valve BVA to control the burner capacity.

Application > Application examples 1.1.3 Modulating-controlled burner with UV control for continuous operation Control: ON/OFF/continuous The PLC uses the actuator IC 20 to move the air butterfly valve BVA to ignition position. The burner BIO/BIC starts at low-fire rate. The UV sensor for continuous operation UVD 1 is also connected in order to monitor the flame, see page 27 (... with UV sensor UVD 1). It notifies the automatic burner control unit for continuous operation IFD 454 or IFD 450 of the presence of a flame. Once the normal operating state is reached, the PLC uses the actuator IC...

3.3 Behaviour during start-up 3.3.2 Start-up without flame signal Once the start-up signal (J) has been applied, the automatic burner control unit checks the burner for flame simulation during the waiting time tW. If no flame simulation is detected during that period, the safety time on start-up tSA 02 then starts to elapse (3, 5 or 10 s). This forms the minimum operating time of the automatic burner control unit and the burner. Voltage is supplied to the pilot gas valve V1 and the ignition transformer. After the safety time on start-up tSA has elapsed and the flame signal has been...
