The Fireye MEP238 Programmer, Selectable recycle/non-recycle function, TFI timing, purge timing, post purge, prove open at start. Ignition de-energized 3 seconds after pilot detected. Provides 8 second pilot stabilization period.
Overview
The Fireye MEP238 is a MicroM series programmer module that provides precise burner sequencing and flame safeguard functionality. Designed for industrial and commercial combustion systems, it manages safe start-up, pilot stabilization, and main flame ignition.
This module offers selectable purge timing, pilot trial-for-ignition (PTFI) duration, recycle or non-recycle operation, and includes both airflow proving and post-purge timing features. It also provides LED status indicators to display sequence and fault conditions, allowing for fast troubleshooting and monitoring.
The MEP238 plugs directly into a MicroM control chassis, forming part of Fireye’s modular flame safeguard system.
