Product Details
Energy Combustion, Ahmedabad importer and suppliers of SIEMENS make burner sequence controller.The Siemens LAL 1.25 and LAL 2.25 are oil burner sequence controllers used for the startup and supervision of oil atomizing burners of medium to high capacity. While they share the same physical footprint and many technical specs, the primary difference lies in air pressure supervision. 1. Comparison of Key Specifications Specification LAL 1.25 LAL 2.25 Air Pressure Monitoring No air pressure supervision. Yes, includes air pressure supervision. Pre-purge Time ($t_1$) $22.5$ seconds $22.5$ seconds Safety Time ($TSA$) $5$ seconds $5$ seconds Post-ignition Time ($t_{3n}$) $15$ seconds $15$ seconds Pre-ignition Time ($t_3$) $2.5$ seconds $2.5$ seconds Voltage $230\text{V}$ AC (or $110\text{V}$ variant) $230\text{V}$ AC (or $110\text{V}$ variant) Power Consumption Approx. $3.5$ VA Approx. $3.5$ VA Flame Detectors QRB1, QRC1, RAR9 QRB1, RAR9 2. Model Specific DetailsSiemens LAL 1.25 Application: Used for yellow-flame or blue-flame burners where the air damper position is checked, but the actual air pressure is not monitored by the controller itself. Flame Supervision: Supports the QRC1 blue-flame detector, making it a popular choice for "Blue Flame" burners. Fault Indication: The lockout indicator is coupled to the sequence switch spindle and shows fault symbols (e.g., failure to ignite, extraneous light). Siemens LAL 2.25 Application: Universal oil burner control for multistage or modulating burners. Air Pressure Check: This model performs a functional check of the air pressure monitor during startup. If the air pressure switch does not close or opens during operation, the LAL 2.25 will trigger a safety lockout. Reliability: Rated for approximately 250,000 startup cycles, ensuring a long service life in industrial environments. 3. General Technical Data Operating Temperature: -20°C to +60°C. Protection Class: IP40 (when mounted correctly). Mounting: Plug-in design using the AGM41 or AGM14 terminal base. Operation: Intermittent (the burner must have at least one controlled shutdown every 24 hours). Weight: Approximately 0.86 kg. Understanding the Sequence Symbols When looking at the transparent reset button during a lockout, you may see: I: Ignition fault (no flame formed during TSA). blacktriangle: Extraneous light during pre-purge. P: Air pressure failure (specific to LAL 2.25).
