MEP230H Fireye Programmer

Overview

The Fireye MEP230H is a microprocessor-based programmer module designed for use with the Fireye Modular MicroM flame safeguard system. It provides burner sequencing, ignition control, and continuous flame monitoring for commercial and industrial burner applications. A key distinguishing feature of the MEP230H is its built-in 8-second pilot stabilization period, which ensures a stable pilot flame is established before the main fuel valve is energized, enhancing ignition reliability in marginal conditions.

Features

• Selectable purge timing (7, 30, 60, 90 seconds) via integrated DIP switches.
• Adjustable pilot trial-for-ignition (PTFI) timing (5 or 10 seconds).
• Selectable recycle or non-recycle operation modes.
• Built-in 8-second pilot stabilization period to improve flame reliability.
• Fixed or selectable post-purge functionality to clear the combustion chamber.
• Smart diagnostic LEDs providing real-time system status and fault codes for troubleshooting.
• Plug-in modular design for easy installation and maintenance within MicroM chassis.
• Proven air flow at start feature to ensure safety before ignition.

Applications

The Fireye MEP230H is ideal for burner management systems requiring enhanced ignition stability and precise sequencing. Typical applications include:

• Industrial and commercial boilers.
• Furnaces and process heaters.
• Two-stage light oil burners requiring specific delays between stages.
• Retrofit projects aiming to improve ignition performance in existing combustion systems.
• Systems with fluctuating or marginal flame conditions where stabilization is critical.
