Siemens Burner Controls

Siemens Burner Controls LME7

The burner control LME7 is a microprocessor-based unit with matching system components for the control and supervision of forced draft burners of medium to high capacity.

LME7 is used for the startup and supervision of multistage or modulating forced draft burners and atmospheric gas burners in intermittent operation. The fuel-air ratio can be set either via an air damper actuator – acting on mechanical or pneumatic ratio control – or via pulse width modulated fans and pneumatic ratio control.


  • Undervoltage detection
  • Electrical remote reset facility
  • Accurate control times thanks to digital signal handling
  • Multicolor indication of fault status and operating state messages
  • Air pressure supervision with function check of air pressure switch during start and operation
  • Repetition limitation
  • Controlled intermittent operation after max. 24 hours of continuous operation (can be parameterized via parameter 239) (depending on type of program module PME7)
  • BCI
  • Unit parameter adjustable either via display or PC software ACS410
  • Connection for program module PME

Siemens Burner Controls

Siemens Burner Controls LFL and LAL

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.

Siemens Flame Detector

Siemens Flame Detector QRA4

UV flame detector for use with burner controls from Siemens for the supervision of gas or oil flames. The flame detector is used for the supervision of gas flames, yellow- or blue-burning oil flames and for ignition spark proving in intermittent operation.

Protectofier 6642 – Combustion Safeguards Flame Monitoring System


Basic combustion safeguard model


Breaker – lockout switch model
Required for automatic lighted installations. System “latches out” after failure to light within ignition trial time and cannot attempt restart until switch is manually reset.
Standard ignition trial time is 15 seconds. Also available in 10-second and 5-second trial time.


Load relay – included for all multi-burner models


Timofier model plugin, fixed time assembly.
The timofier provides purge time and ignition trial time. The ignition trial time is deducted from the motor time cycle (1/2, 1, 1-1/4, 2, 3, 4, and 6 minutes available for manual and automatic models; 10 minutes for manual model only) to purge the time.

Standard ignition trial time is 15 seconds. Also available in 10-second and 5-second trial time. Specify both purge and ignition times. Purge time shall allow system to have a minimum of four fresh air changes.
