The Fireye EPD170 is a programmer module designed for use with the Flame-Monitor Burner Management Control System. It provides start-up programming, safe-start check, and flame monitoring supervision, ensuring safe and efficient operation of industrial burners. The EPD170 enforces critical safety checks, including open damper (high purge) prepurge, proof of low fire position, and fuel valve end switch verification. It continuously monitors limit switches, airflow switches, and fuel pressure switches through its running interlock circuit, initiating a safety lockout if any circuit opens at an inappropriate point in the control cycle. The module features seven LED indicators to display the current operating status and the reason for the last lockout condition. Additionally, it includes an RJ45 connector for interfacing with a remote alphanumeric display (ED510) and two RJ-style connectors for connection to an E500 communication interface. The EPD170 is equipped with built-in Modbus-RTU communications and provides a 0-10 VDC test jack signal to indicate flame signal strength. It is important to note that the EPD170 has been classified as obsolete; for current applications, refer to the Flame-Monitor EP Programmer Modules.
