EP161 Fireye Programmer

Overview

The Fireye EP161 is a microprocessor-based programmer module designed for use with the FLAME-MONITOR Flame Safeguard and Burner Management Control System (specifically E100 and E110 chassis). It serves as the central control unit for industrial and commercial burners, providing essential startup programming, safe-start checks, and continuous flame monitoring. The EP161 is characterized by its extended Main Trial for Ignition (MTFI) capabilities and is engineered to ensure that all safety interlocks, such as air flow and fuel pressure switches, are proven at the correct points in the combustion cycle to prevent hazardous conditions.

Features

• Startup Programming and Safe-Start Check: Automates the ignition sequence while ensuring the system is in a safe state before proceeding.
• Flame Monitoring Supervision: Provides continuous oversight of the flame signal to ensure safe burner operation.
• Selectable Operational Characteristics: Utilizes six side-mounted dipswitches to configure functions such as blower motor start delay and extended purge timing.
• Safety Interlock Monitoring: Constantly tracks the status of limit switches, airflow switches, and fuel pressure switches through a running interlock circuit.
• Diagnostic Intelligence: Stores operational history, including burner cycles, run hours, and lockout data, accessible via an ED510 display or communication interfaces.
• Plug-in Design: Allows for easy installation and replacement within the Fireye FLAME-MONITOR chassis.
• Communication Support: Includes an RJ45 connector for display modules and supports Modbus protocol via RJ12 connectors for remote monitoring.

Applications

The Fireye EP161 is primarily used in commercial and industrial boiler applications and heating systems that require a high degree of safety and automated sequencing. It is specifically designed to work with Fireye EB700, E100, and E110 chassis. It is ideal for managing burners that utilize gaseous or liquid fuels where precise timing for purge and ignition is critical for system reliability and compliance with safety codes. Common environments include manufacturing plants, large-scale HVAC installations, and power generation facilities.
