EP170 Fireye Programmer

Overview

The Fireye EP170 is a microprocessor-based programmer module designed for use with the FLAME-MONITOR Burner Management Control System, specifically compatible with E100 and E110 chassis. It serves as the central control unit to provide proper burner sequencing, ignition, and flame monitoring protection for automatically ignited oil, gas, and combination fuel burners. The EP170 is characterized by its early spark termination feature and its ability to manage complex safety interlocks to ensure safe burner operation.

Features

• Microprocessor-based design for precise timing and sequencing.
• Early spark termination support via terminal 18.
• Six dipswitches located on the side of the module to determine operational characteristics such as forced blower motor start delay and extended purge timing.
• Running interlock circuit that constantly monitors limit, air flow, and fuel pressure switches.
• Non-volatile memory that retains control status and lockout history even during power failures.
• Plug-in design for ease of installation and maintenance.
• RJ45 style connector for interfacing with integral or remote alpha-numeric displays like the ED510.
• Remote reset and remote data communications capability.

Specifications

• Supply Voltage: 120 VAC (+10%, -15%) 50/60 Hz.
• Temperature Rating: -40 to 140 F (-40 to 60 C).
• Purge Timing: Selectable (30 seconds minimum).
• Pilot Trial for Ignition (PTFI): 5 or 10 seconds (selectable).
• Main Trial for Ignition (MTFI): 10 seconds.
• Flame Failure Response Time (FFRT): 4 seconds (maximum).
• Power Consumption: 25 VA.
• Shipping Weight: Approximately 2.5 lbs.

Applications

The EP170 programmer module is utilized in commercial and industrial combustion systems to supervise start-up programming and flame monitoring. It is designed for use with various flame scanners, including ultraviolet (UV), infrared (IR), and flame rods. Common applications include:

• Industrial boilers and furnaces.
• Process heating equipment.
• Burner management systems requiring early spark termination for smoother ignition cycles.
• Systems utilizing Fireye EB700 or E110 chassis and ED510 display modules.
