LMV ECOSYSTEM



Fully Integrated, Easy-to-Use HMI


Accuracy is the Key to Control



Programming and commissioning of the LMV5 takes minutes, not days. Simply log in, select the programming option and define the specific parameters. It is that easy!


  • User-friendly, menu system for fast programming and commissioning
  • Quickly access and monitor the system at all times
  • Real text annunciation of fault conditions for fast troubleshooting
  • Multi-level password protection for added security
  • Real-time ModBus communication

Driven by a digital Can-Bus signal, the movement of the SQM4 actuator is accurate to 1/10th of one degree. A digital feedback signal ensures the correct position is maintained throughout the modulating range.

Accurate control ensures that the burner will always perform with repeatability and accuracy as well as within the recommended safety parameters.

Additional Options for Saving Energy

High impact options including; O2 trim system, Variable Frequency Drive, Touchscreen and PC Commissioning Tool meet specific control needs, improve process control and reduce energy costs.


Fuel Air Ratio Control & Flame Monitoring


Communication & Annunciation

The Siemens LMV3 is capable of positioning up to 2 actuators and one Variable Speed Drive (VSD) simultaneously on programmed curves with an accuracy of 0.2 degree (actuators) and 0.1% (VSD). Standard programs offer many fuel train options, including staged oil and PWM control.

  • Separate, programmable actuator positions for ignition and low -fire
  • Nine programmable points per curve, per fuel
Capability to use a maximum of two fuel actuators with independent combustion curves. 

Reliable Flame Monitoring:

  • Optional UV or Flame Rod supervision
  • No exchange of amplifiers or controls necessary
  • Simple configuration selects appropriate flame detector

The LMV system has a variety of communications and annunciations which include:

  • RS485 Modbus RTU Communications
  • Access to more than 40 read/write registers enable precise burner supervision and control
  • Registers include:
    • Fault History
    • Lockout History
    • Flame Signal Intensity
    • remote firing rate control
    • Fuel Flow (via flow meters connected to LMV3)

ACS410 PC Commissioning Tool

  • Windows-based
  • Optional Commissioning tool
  • Ability to configure, back-up and restore information to a PC
  • View real time data
  • Trend, log, and print data
