Fireye MEP235 Module

The Fireye MEP235 Module is a high-performance MicroM flame safeguard programmer designed for precision burner management in commercial and industrial environments. This plug-in module is engineered for use with MEC120 and MEC230 chassis, providing critical sequencing logic for automated burner operation. The MEP235 distinguishes itself from the base MEP230 series with advanced lockout parameters, including a mandatory 10-second air flow verification window at start-up and a dedicated flame failure lockout that secures the system immediately upon the loss of a flame signal during the firing period.

Equipped with Programmer Selectable Timing, the unit features on-board DIP switches that allow technicians to configure purge timing (7, 30, 60, or 90 seconds), Pilot Trial for Ignition (PTFI), and recycle or non-recycle modes. These hardware-level settings are permanently stored in the module's EEPROM after 8 hours of operation, ensuring stable and repeatable combustion cycles. Integrated LED diagnostics provide real-time status updates and fault codes, streamlining troubleshooting for field contractors managing complex boiler or process heating systems.

• Enhanced Safety Logic: Features a dedicated flame failure lockout and air flow proving within 10 seconds of cycle start to prevent hazardous conditions.
• Field Configurable: DIP switch accessibility for selectable timing allows for quick adaptation to specific burner requirements without requiring external tools.
• Modular Compatibility: Designed for seamless integration with Fireye MicroM controls, utilizing standard wiring bases to minimize retrofit time.
• Robust Diagnostics: Multi-color LED status indicators provide immediate site feedback on sequencing and lockout causes.

• How do I change the purge timing on the MEP235? Timing is adjusted via the internal DIP switches prior to the 8-hour permanent storage window; consult Fireye bulletin MC-5000 for specific switch positions.
• Is the MEP235 compatible with older Fireye chassis? It is primarily designed for the MicroM Modular series, specifically the MEC120 and MEC230 chassis.
• What happens if the internal memory is locked? Once the 8-hour continuous operation threshold is met, timing and recycle settings are fixed and the module cannot be reconfigured.
