Siemens Combustion LFL1.635-110V Control
The Siemens Combustion LFL1.635-110V Control is a heavy-duty, electro-mechanical primary flame safeguard designed for gas, oil, or dual-fuel forced-draft burners of medium to high capacity. This 110V burner control is engineered for intermittent operation, requiring a controlled shutdown every 24 hours to execute internal self-checks. For technicians working with multistage or modulating burners, the LFL1.635-110V provides comprehensive sequencing, including a 66-second pre-purge time (at 50 Hz) and a 2.5-second safety time, ensuring stable and safe combustion management in industrial boiler systems or stationary air heaters. With its flame monitoring circuit supporting both UV detectors and ionization probes, this controller offers versatile supervision for direct spark or interrupted pilot construction.
Key Benefits:
- Universal Compatibility: Ideally suited for forced-draft burners, managing gas, oil, and dual-fuel systems with checked air damper control.
- Enhanced Safety Logic: Features an integrated flame signal amplifier and automatic self-testing of the flame supervision circuit during each startup.
- Visual Diagnostics: A built-in program spindle provides a visual sequence indication through the front window, simplifying field troubleshooting for contractors.
- Rugged Construction: Encased in impact-proof and heat-resistant plastic with an IP40 rating, designed to withstand demanding mechanical room environments.
- Maintenance Ready: Includes an exchangeable unit fuse and a spare fuse located directly within the housing to minimize downtime during service calls.
Common Questions:
Can I use the LFL1.635-110V for continuous burner operation?
No. This model is strictly for intermittent operation. If your system requires 24/7 continuous firing without a daily shutdown, you must utilize the LGK16 series to meet safety standards.
Which flame detectors are compatible with this control?
The unit is designed to interface with Siemens QRA series UV sensors or standard ionization probes, providing flexibility depending on your combustion setup.
How does the frequency affect timing?
Switching times like pre-purge and safety timing are based on a 50 Hz frequency; if operating on 60 Hz, these times will be approximately 17% shorter.
What does the orange lockout light indicate?
An orange light confirms the unit has entered a lockout state. This is often triggered by a loss of flame signal, air pressure switch failure, or the air damper failing to reach the required position during the startup sequence.
