LDU11.323A27 Siemens gas valve leak detector

LDU11.323A27- Gas valve leak detector, t3=2.5 s, t4=2.5 s, AC220 240 V

LFL1... burner control device designed specifically for forced air burner control and monitoring can be used for direct ignition or medium to high power burners with ignition burners. Fuel and gas are universal and can be applied to fixed preheating air burners WLE according to DIN 4794 standard

The difference between the 01 series and the 02 series lies in: ① the safety time of ignition burners with ignition gas valves is different; ② the controller for high-power atmospheric combustion is LFL1.638. If the burner needs continuous operation control, ③ for burners using ignition gas valves, the safety time is different.  

After the allowed post ignition time of LFL1, the detection electrode and flame simulation test are immediately restored. The fuel valve that is not closed or not closed immediately locks the controller unit of the burner after the allowed afterburning time. The detection electrode and flame simulation inspection only ends when the pre purge time at the next burner start is completed- During each start-up of the burner, the correct operation of the flame monitoring circuit is automatically verified- The controller contacts used to release fuel are inspected during each subsequent purge time to ensure that the contacts do not close- A built-in fuse unit protects the contacts of the controller from overload.

Combustion controller ? For medium and large capacity burners with forced ventilation for fuel, gas, or dual fuel ? For intermittent operation burners with multiple sections or continuous proportions ? With damper detection ? Flame monitoring - UV flame detector QRA The ion probe LFL1... series controller is particularly suitable for OEM manufacturers who integrate combustion control into their products Purpose - Monitoring forced draft burners with expandable flames or pilot flame (ignition) interruptible structures - Medium to high capacity - Intermittent operation (with at least one controlled shutdown every 24 hours) - Multi stage or continuous proportional burners - Dual fuel burners - Fixed air preheaters 01 and 02 series. For pilot flame (ignition) burners equipped with pilot flame gas valves, the main difference lies in the length of safety time. LFL1.638 is suitable for large capacity atmospheric burners

This burner control is used to continuously operate multi-stage or regulate medium to high capacity burners, and check the air damper control through air pressure monitoring. The burner control device has passed the EN298 and CE certification, and complies with the gas appliance and electromagnetic compatibility directives. The functions include fault lock indicator light, fault signal light, and reset button.

The burner control unit has a self checking flame monitoring circuit, which not only starts the required safety measures when the flame signal is too early or missing, but also when any fault occurs in the flame detector, cable or flame signal amplifier (which may simulate the flame signal during burner operation). This control device is reliable and suitable for a wide range of applications, including fuel and gas combustion plants that must use self checking flame monitoring systems, such as continuous use burners, intermittent operation burners, and burners in factories that require self checking for burner monitoring due to safety requirements. Suitable for gas, oil, and dual fuel burners.

Burner control is suitable for: medium to high capacity gas, oil, or dual fuel forced ventilation burners, intermittently operated multi-stage or adjustable burners, with inspected air damper control, flame supervision, and equipped with ultraviolet detector QRA And ionization probe, burner control for oil or gas burners in accordance with EN 298:2012, suitable for air heaters (WLE)
