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.

Features:

  • 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

Protectofier 6642 – Combustion Safeguards Flame Monitoring System

FORM 6642VA

Basic combustion safeguard model

FORM 6642VB

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.

FORM 6642VL

Load relay – included for all multi-burner models
