The Saacke Flame Failure Memory (FFM) unit, part number 11037620, is a critical safety and control component designed for industrial burner management systems. Operating on a 230VAC power supply, this solid-state electronic module serves as the central logic unit for monitoring, sequencing, and safeguarding the burner ignition and operation process. Its primary function is to prevent unsafe conditions by detecting flame failure and locking out the system if a stable flame is not established or maintained.
Key Features & Functions
-
Flame Supervision:Â Continuously monitors the flame signal from an ionization rod or UV scanner to confirm the presence of a flame during the start-up sequence and main operation.
-
Programmed Start-Up Sequence:Â Automatically controls the pre-purge, ignition trial, and main fuel valve activation according to established safety timers.
-
Flame Failure Memory (Lockout):Â In the event of a flame failure during operation or an unsuccessful ignition attempt, the unit enters a safety lockout state. This immediately shuts off the fuel supply and requires a manual reset to prevent hazardous fuel accumulation.
-
230VAC Operation:Â Designed for direct integration into standard industrial control panels and power circuits common in Europe and other regions using 230VAC.
-
Safety Compliance:Â Built to meet stringent international standards for burner control and safety (e.g., similar to principles in EN 298, though specific certification should be verified).
-
LED Status Indication:Â Typically features LED indicators to display operational status such as power-on, pre-purge, ignition, flame signal, and lockout, aiding in troubleshooting.
-
Solid-State Reliability:Â Utilizes electronic circuitry for high reliability, fast response times, and long service life without the wear and tear of mechanical relays for core safety functions.

Why This Product is Critical
The Saacke FFM Unit 11037620 is an essential safety device. It ensures that:
-
Fuel is not released without a proven ignition source.
-
The combustion chamber is purged of any unburned gases or fumes before an ignition attempt.
-
The burner shuts down safely if the flame is unexpectedly extinguished, preventing dangerous fuel buildup and potential explosions.
-
Operational faults are clearly indicated, allowing for quick diagnosis and repair.
