Fireye Programmer – EP Series

Applications & Benefits

The Fireye EP Series Programmer Modules are designed for use with the Flame-Monitor® burner management control system,
providing safe, configurable sequencing for industrial boilers, furnaces, and process heaters. They deliver reliable start-up logic,
continuous flame supervision, and rigorous safety checks to minimize nuisance trips and improve uptime.

Series Overview

Models include EP100S, EP200S, EP300S (extended purge); EP160, EP161 (extended MTFI), EP163 (programmable), EP170, EP174 (early spark termination), EP165, EP166 (pilot stabilization), EP177 (early spark termination + programmable); EP260, EP265 (pilot stabilization), EP270 (early spark termination); and EP380, EP381, EP382, EP383, EP390.

Operational Customization

• Dipswitch settings (most models): Forced blower motor start delay (Switch 1—inactive on some), extended purge timing (Switches 3–5), and 3-P running interlock requirement (Switch 6).
• Programmable via ED510 Display Module: EP163, EP177, and EP383 use the ED510 in place of dipswitches for advanced configuration.

Key Safety Functions

• Start-up programming & safe-start check to verify system readiness and correct ignition sequencing.
• Flame monitoring supervision for ongoing burner safety.
• Critical safety checks including open damper (high purge) prepurge, proof of low fire position, and fuel valve end switch verification.
• Running interlock circuit continuously monitors limits, airflow, and fuel pressure switches; improper opening triggers lockout or recycle based on module settings.
