MEP397 Fireye Programmer

Overview

The Fireye MEP397 is a microprocessor-based flame safeguard programmer module within the MicroM family. Designed for commercial and industrial burner management, it provides automatic ignition and continuous flame monitoring for systems using interrupted pilot burners. This plug-in module ensures safe combustion by managing sequencing logic, including pre-purge, ignition, and safety shutdown. It is engineered to be backward compatible with existing M-Series controls and requires manual reset after a safety lockout, making it ideal for safety-critical applications where automatic retries are not desired.

Features

• Integrated 15-second fixed pre-purge cycle to clear the combustion chamber before ignition.
• Designed specifically for interrupted pilot burner systems with early spark termination.
• Non-recycle operation mode that ensures the system locks out upon flame failure rather than attempting an automatic restart.
• Smart diagnostic LED indicators provide real-time feedback on system status, flame sequence, and fault codes.
• Modular plug-in design allows for quick installation and easy replacement within MicroM chassis.
• Run/Check switch included to assist in testing pilot size and stabilization during commissioning.
• Compatible with a wide range of MicroM chassis, amplifiers, and display modules (such as the ED510).

Specifications

• Model Number: MEP397
• Purge Time: 15 seconds (fixed)
• Pilot Trial for Ignition (PTFI): 7 seconds
• Main Trial for Ignition (MTFI): 5 seconds
• Flame Failure Response Time (FFRT): 0.8 seconds nominal (4 seconds maximum)
• Pilot Type: Interrupted
• Operation Mode: Non-recycle (Manual reset required)

Applications

The MEP397 is utilized in combustion systems requiring controlled ignition sequencing and rigorous flame supervision. It is commonly installed in boilers, furnaces, process heaters, and commercial burner systems firing gas or oil. It is specifically selected for environments where industrial safety standards dictate a lockout over an automatic recycle in the event of a flame failure. When integrated into a complete MicroM system with appropriate scanners and amplifiers, it provides comprehensive safety control for diverse industrial heating applications.
