MEP235 Fireye Programmer

Overview

The Fireye MEP235 is a MicroM series flame safeguard programmer module designed for use with Fireye modular burner control systems. This plug-in module provides essential burner sequencing, including prepurge, pilot trial for ignition, and flame monitoring. It is distinguished by its advanced safety logic, which includes a dedicated lockout feature if airflow is lost after the start of a cycle or if flame failure occurs during firing, ensuring reliable and safe operation of commercial and industrial burners.

Features

• Selectable purge timing (7, 30, 60, or 90 seconds) and PTFI timing (5 or 10 seconds) via DIP switches.
• Configurable recycle or non-recycle operation modes.
• Lockout on airflow open 10 seconds after the start of a cycle.
• Selectable lockout on airflow open after flame is proven.
• Dedicated lockout functionality after loss of flame.
• LED indicator lights for status monitoring and diagnostic fault coding.
• Plug-in design allows for easy installation into MEC120 or MEC230 chassis.
• Micro-controller based technology eliminates dependence on discrete components for timing.
