MEP537 Fireye Programmer

Overview

The Fireye MEP537 is a microprocessor-based programmer module designed for use with the Fireye Modular MicroM Flame Safeguard control system. It provides automatic ignition sequencing and continuous flame monitoring for commercial-sized heating and industrial process burners. As a “recycle” programmer, it is specifically designed to provide one automatic recycle on a main flame failure, enhancing system reliability and reducing manual resets in industrial environments.

Features

• Selective DIP switches for customizing purge timing, PTFI timing, air flow proof, and post-purge
• Plug-in design for easy installation and maintenance within MicroM chassis
• Smart LED indicators for real-time operating status and diagnostic lockout codes
• Run/Check switch to facilitate pilot testing and stabilization without full burner cycles
• Backward compatibility with existing Fireye M-Series control systems
• Integration support for optional ED510 display and Modbus communications

Specifications

• Model: MEP537
• Main Trial-for-Ignition (MTFI): 10 seconds
• Purge Timing: Selectable (7, 30, 60, or 90 seconds)
• Post Purge: Selectable (Disabled or 15 seconds)
• Supply Voltage: 120 VAC (compatible with MEC120 and MEC230 chassis)
• Operating Temperature: -40 degree F to 140 degree F (-40 degree C to 60 degree C)
• Flame Failure Response Time: Determined by the selected amplifier module (0.8s or 3s)
• Recycling: Provides one recycle upon main flame failure

Applications

The MEP537 is used in commercial and industrial burner management systems firing any fuel type, including natural gas, propane, and light oil. It is ideally suited for boilers, furnaces, and process burners where an automatic retry on flame failure is preferred over an immediate safety lockout. It is compatible with MicroM series components including various flame scanners (UV, Infrared, Flame Rod) depending on the selected amplifier module.
