EP177 Fireye Programmer

Overview

The Fireye EP177 is a microprocessor-based programmer module designed for use with the Flame-Monitor Burner Management Control System (E100 and E110). It provides essential start-up programming, safe-start checks, and continuous flame monitoring for commercial and industrial burners. A distinguishing feature of the EP177 is its “early spark termination” capability and the requirement of an ED510 Display Module for programming its operational parameters, such as purge timing and ignition sequences.

Features

• Early Spark Termination: Specifically designed to terminate the ignition spark early in the cycle.
• Programmable Parameters: Uses the ED510 Display Module to set purge timing, proving of air flow, and high/low fire positions.
• Infinite Hold: Features an infinite hold on the M-D circuit at the end of the low fire start, waiting for the low fire start switch to close.
• Safety Lockout: Initiates a safety lockout if running interlocks (limit, air flow, or fuel pressure switches) open at an improper point in the cycle.
• Plug-in Design: Facilitates easy installation and replacement within the Flame-Monitor system.

Specifications

• Compatibility: Fireye E100 and E110 Flame-Monitor chassis.
• Purge Timing: Programmable via ED510 (minimum 30 seconds).
• Flame Failure Response Time (FFRT): 4 seconds.
• Pilot Trial for Ignition (PTFI): 5 seconds.
• Main Trial for Ignition (MTFI): 10 seconds.
• Shipping Weight: Approximately 2 lbs.
• Dimensions: 7 x 7 x 2 inches.

Applications

The EP177 is utilized in industrial and commercial combustion systems, including industrial boilers, furnaces, and process heaters. It is ideal for applications requiring precise control over the ignition sequence and early spark termination. It is commonly used in refining, petrochemical, power generation, and steel manufacturing environments where rigorous flame supervision and safety checks are mandatory to prevent nuisance trips and ensure safe operation.
