MEP103 Fireye Programmer

Overview

The Fireye MEP103 is a specialized plug-in programmer module designed for use with the MicroM series flame safeguard system. This microprocessor-based controller manages the automatic ignition and continuous flame monitoring of commercial and industrial burner applications. It is engineered to provide precise timing for critical safety functions, including a fixed 10-second Spark Igniter Sensing Period (SISP) and a 10-second Main Trial for Ignition (MTFI). A key safety feature of the MEP103 is its ability to attempt a single retry upon pilot failure and its fixed 30-second post-purge cycle, which ensures the combustion chamber is cleared of residual gases following a shutdown or lockout.

Features

• Microprocessor-based logic for high-precision timing and operational sequencing.
• Fixed 10-second Spark Igniter Sensing Period (SISP) and 10-second Main Trial for Ignition (MTFI).
• Automatic single retry functionality on pilot failure to enhance system reliability.
• Fixed 30-second post-purge cycle to evacuate volatile gases from the heat exchanger.
• Plug-in design compatible with standard MicroM wiring bases for easy installation and maintenance.
• Integrated LED diagnostics for immediate visual feedback on sequence status and lockout causes.
• Robust internal circuitry designed to withstand the thermal and electrical stresses of mechanical room environments.

Applications

The MEP103 is ideally suited for facilities requiring dependable burner management and flame safeguard protection in commercial and industrial settings. It is commonly used in industrial furnaces, boilers, gas turbines, engines, thermal oxidizers, and incinerators. As part of a complete MicroM system, it provides safe startup and monitoring for burners fired by gas or light oil fuels. It is a critical component for HVAC contractors performing site maintenance or system upgrades where specific safety timings and post-purge cycles are required by local codes or equipment specifications.
