Landis & gyr lal2.25 oil burner controller used

What is the Landis & Gyr LAL2.25 Controller?

The LAL2.25 is an automatic oil burner safety controller, which is used on medium to large-sized burners. It will ensure that the burner starts up correctly, senses the presence of a flame, and shuts down if it senses a fault.

This controller belongs to the LAL series by Landis & Gyr (now Siemens), a global leader in burner automation systems.

Main Functions of LAL2.25:

• Controls burner start-up, ignition, and flame monitoring
• Safety shutdown on malfunction
• Photicell flame sensors verify combustion
• Modulating and 2-stage burners
• Fuel supply is prevented when no flame exists

Features & Specifications

LAL2.25 burner controller has been developed to ensure that oil-fired heating systems are maximum safe and reliable. Some of the most remarkable features of the product are given below:

1. Reliable Flame Monitoring
The LAL2.25 includes a flame detector that actually double-checks the presence of a flame before fuel flow is allowed. In case the flame is not detected within a set period, the controller will halt the burner.

2. Automatic Start-Up Sequence
The unit automatically supervises the burner pre purge, ignition and the flame monitoring sequence, thus ensuring smooth performance.

3. Built-in Safety Lockout
The controller will lock out if it detects an ignition failure, flame failure, or sensor fault; the system will remain shut off until a repair has been made.

4. Compact & Durable Design
The LAL2.25 is made using high-quality materials to withstand harsh industrial environments and can run under many conditions.

5. LED Status Indications
The controller includes LED indications that are helpful for diagnosing burner status and faults for any servicing technicians.
