EP390 Fireye Programmer

Overview

The Fireye EP390 is a programmable burner management module designed for use with the Fireye Flame-Monitor Control System. It provides essential start-up programming, safe-start checks, and continuous flame monitoring for commercial and industrial burner applications. The EP390 is specifically engineered for systems that do not require modulation, focusing on fixed-fire or simple on/off burner sequences. It ensures that all safety interlocks, such as airflow and pressure switches, are proven before allowing the ignition sequence to proceed, and it will initiate a safety lockout if any limits are tripped during operation.

Features

• Selectable 5 or 10 second Trial-for-Ignition (TFI) timing to suit specific burner requirements.
• Configurable recycle or non-recycle operation via onboard dipswitches for the running interlock circuit.
• Integrated RJ45 connector for interfacing with alpha-numeric displays like the ED510 for local diagnostics and setup.
• Non-modulation design specifically for fixed-control burner installations.
• Comprehensive safety monitoring of limit switches, fuel pressure, and air flow interlocks.
• Backward compatibility with ED500 series displays and E500 communication interfaces.
• Safe-start check to verify the absence of flame before initiating the start-up sequence.

Specifications

• Purge Timing: 90 seconds (minimum), selectable and can be increased via dipswitches.
• Pilot Trial for Ignition (PTFI): 10 seconds.
• Main Trial for Ignition (MTFI): 10 or 15 seconds.
• Flame Failure Response Time (FFRT): 4 seconds maximum.
• Operating Voltage: 120 VAC (+10%, -15%) 50/60 Hz.
• Power Consumption: 25 VA.
• Temperature Rating: -40°F to 140°F (-40°C to 60°C).
• Shipping Weight: 2.5 lbs (1.13 kg).
• Compatibility: Designed for use with E110 and EB700 chassis.

Applications

The Fireye EP390 is used in commercial and industrial combustion systems where precise timing for purging and ignition is critical but firing rate modulation is not required. It is commonly found in large boilers, ovens, and furnaces that operate on a single-stage firing principle. Because it is part of the Flame-Monitor system, it is ideal for facilities requiring detailed diagnostic feedback via display modules and those integrating with broader building management systems through serial communication.
