Siemens LFL and LAL burner controls provide burner sequencing and flame monitoring for the supervision of individual gas, oil,
or dual fueled burners. With an incomparable record for safety and reliability, the economical LFL continues to be one of the
most popular, globally approved flame safeguard controls.
- 24 terminals provide the functionality of high-priced competitive products
- Built-in flame amplifier for both UV scanner or flame rod for the LFL
- Various timings available to meet application requirements
- Globally approved - cULus, FM, CSA, CE

LEC1.. Control Unit
|
Siemens LEC1... control units are designed for the fully automatic startup and supervision of forced draft oil or gas burners where flame supervision should or must be carried out by separate flame safeguards, e.g. with:
- Double supervision of the main flame or pilot and main flame by 2 identical or different detectors
- Supervision of forced draft oil / gas burners with different types of detectors, depending on the selected operating mode
- Multiflame supervision, that is, central and simultaneous control of the startup and supervision sequence of several burners the flames of which must be individually
supervised by 1 or 2 flame safeguards each
|
Siemens LGA.. gas burner controls are used for the startup and supervision of atmospheric gas burners
of small to medium capacity (without fan) in intermittent operation.

|
Siemens LGB.. Burner controls are for the supervision of 1- or 2-stage gas or gas / oil burners of
small to medium capacity (typically up to 350 kW), with or without fan, in intermittent operation.
|
Siemens LOA.. oil burner controls are for the supervision, startup and control of 1- or 2-stage forced
draft oil burners in intermittent operation. Oil throughput up to 30 kg/h.

LAE10 / LFE10 Burner Controls
|
- Flame safeguards for burners with intermittent operation
- The LAE10 is used for the supervision and indication of oil flames
- The LFE10 is used for the supervision and indication of gas and oil flames
- Supplementary Data Sheets for flame detectors, refer to N7712 and N7713
- For flame supervision systems for continuous operation
|
The LFE50... together with the QRA50M / QRA51M form a self-checking UV flame
supervision system (DETACTOGYR®) designed for use with continuously operating
oil or gas burners or burners operating without interruption for more than
24 hours.

 LDU11... Valve Proving Control
|
The LDU11 gas valve leak test control checks for leakage through the shutoff valves prior to burner start-up and/or immediately after burner shutdown. The cost effective, easy to install LDU11 adds a substantial degree of safety to any combustion system.
- Checks both shutoff valves for leakage
- Improves system safety
- No inlet gas pressure limatations
- Globally approved - cULus, FM, CSA, CE
- Easy-to-read dial indicates progress of test program
|
- With self-checking flame signal amplifier
- For continuously operating multistage or modulating oil or gas burners of
medium to high capacity
- With air pressure supervision for checked air damper control

LMG2.. Burner Control
|
The LMG2... Burner controls are now obsolete. They were for the supervision of 1- or 2-stage gas or forced draft gas / oil
burners of small to medium capacity (typically up to 350 kW) in intermittent operation. Replaced by the LME series.
|
The LME2... Burner controls are for the supervision of 1- or 2-stage gas or forced draft gas / oil
burners of small to medium capacity (typically up to 350 kW) in intermittent operation. Replaces the LMG series.
