Siemens Display Unit AZL52.00 B1 for LMV 51/ LMV 52 (230 V AC)

Product Details

The Siemens AZL series consists of display and operating units designed to interface with the LMV (Linkageless Management) and LME7 burner management systems. They serve as the primary window into the burner's logic, allowing for commissioning, parameter adjustment, and real-time monitoring. 1. Primary AZL Models Model Compatible System Type Key Features AZL21.00A2 LMV2 / LMV3 Icon-based LCD Small, cost-effective, uses symbols for navigation. AZL23.00A2 LMV2 / LMV3 Text-based LCD Supports multi-language plain text messages. AZL52.00B1 LMV51 / LMV52 High-res Graphic Large screen, trend logging, and complex curve visualization. AZL66 LMV6 Touchscreen Modern interface for the latest generation of LMV6 controllers. 2. Technical SpecificationsAZL21 / AZL23 (For Mid-Range Burners) Operating Voltage: DC $12\text{V}$ (Powered via the LMV base unit). Communication: Serial interface (RJ11 or specialized cable). Display: 8-digit LCD with backlighting. Ambient Temp: $-20\text{°C}$ to $+60\text{°C}$. Protection Class: IP40 (Front side IP54 when mounted with a sealing gasket). Functionality: * Set-point adjustment. Error code display and reset. Phase position monitoring. AZL52 (For High-Capacity Industrial Burners) Operating Voltage: DC $24\text{V}$ (Powered via the LMV5 base unit). Communication: CAN bus interface. Display: Monochrome backlit graphic display ($160 \times 80$ pixels). Memory: Internal memory for parameter backup and data logging. Ambient Temp: $-20\text{°C}$ to $+50\text{°C}$ (Strictly monitored). Functionality: * Visualization of the fuel/air ratio curves (V-points). Efficiency calculations ($\eta$). $O_2$ trim monitoring and calibration. Operating hour counters and start counters. 3. Key Functional Roles Commissioning Tool: The AZL is used to "teach" the LMV system the ratio curves by driving the SQM actuators to specific positions and storing them. Diagnostics: Instead of simple blink codes, the AZL provides specific fault codes (e.g., Fault 04: No flame signal) and the exact phase of the startup when the fault occurred. Parameterization: It allows technicians to adjust timings (pre-purge, safety times) and safety limits without needing a PC. Remote Mounting: AZLs can be mounted on the front of the control cabinet door using specialized mounting frames, keeping the high-voltage LMV base unit safe inside the panel. 4. Mounting & Accessories Cable Length: Standard cables are $1.2\text{m}$ to $3\text{m}$, but CAN bus extensions for the AZL52 can reach up to $100\text{m}$ with proper shielding. Mounting Frames: AGG3.131 (for AZL2x) or AGG3.150 (for AZL5x) are used to secure the displays to the panel door.
