LME71.111A1PKG-PRG18 Siemens Flame Safeguard

Overview

The Siemens LME71.111A1PKG is a high-performance, pre-programmed flame safeguard assembly designed for the supervision of 1-stage or 2-stage gas forced draft burners. As a microprocessor-based burner control, it manages the startup and continuous operation of combustion systems, ensuring safety by monitoring the flame and controlling safety shutoff valves. This package is an all-in-one solution that includes the LME71.000A1 basic unit, the PME71.111A1 program module, and a complete connector plug set (AGG3.710). It is engineered for intermittent operation and is ideally suited for medium to large-capacity industrial thermal process applications.

Features

• Comprehensive assembly includes the LME71.000A1 base unit, PME71.111A1 programming chip, and connector plug set
• Integrated multicolor LED signal lamp displays operating status, program sequences, and detailed fault notifications
• Programmable purge timing and electrical remote lockout reset capability for operational flexibility
• Built-in Proof of Closure (POC) input to monitor gas valve status and ensure 100% closure before ignition
