Q1: What is the Siemens LMV51.100C2?
It is a Burner Management System for forced draft burners, integrating burner control, electronic fuel-air ratio control, and an integrated PID load controller for temperature or pressure regulation. It supports up to 4 actuators and is certified to SIL 3 .
Q2: What is the difference between LMV51.100C2 and LMV51.000C2?
The LMV51.100C2 (this item) includes an integrated PID load controller for direct boiler temperature or pressure regulation. The LMV51.000C2 does not have this integrated controller and requires an external load controller .
Q3: How many actuators does this unit control?
It controls up to 4 actuators (SQM45/SQM48/SQM9x series) for air dampers and fuel valves .
Q4: What flame detectors are compatible?
It supports QRI infrared detectors (continuous operation), QRB photoresistive detectors (intermittent operation), and ionization probes. QRA UV detectors are compatible with the appropriate AGQ accessory .
Q5: Does this unit require an external display?
Yes. The LMV51.100C2 requires an AZL52 display and operating unit (or PC with ACS450 software) for commissioning, parameter setting, and diagnostics. The display is not included and must be ordered separately .
Q6: What is the designed lifetime of this unit?
The designed lifetime is 250,000 burner startup cycles, equivalent to approximately 10 years of normal heating operation. After reaching this threshold, the unit should be replaced by authorized personnel .
Q7: What safety certification does this unit carry?
It is certified to SIL 3 according to IEC 61508, the highest safety integrity level for burner management systems .
Q8: Does the LMV51.100C2 support O2 trim control?
No. O2 trim control is a feature of the LMV52 series, not the LMV51. The LMV51 focuses on electronic fuel-air ratio control without closed-loop O2 feedback .
Q9: What is the supply voltage?
The supply voltage is AC 230 V, 50/60 Hz .
Q10: What is the operating temperature range?
The operating range is -20°C to +60°C .
Q11: What should I verify before ordering?
Always verify the exact part number (LMV51.100C2 for integrated PID load controller), confirm your burner requires up to 4 actuators, ensure you have the AZL52 display for commissioning, and check whether your application requires O2 trim control (which would require an LMV52 model instead).
