SAACKE F‑GDSA‑1 / F‑GDSA‑2 Feuerungsautomaten
SAACKE F-GDSA-1 and F-GDSA-2 series are industrial-grade automatic burner sequence controllers (Feuerungsautomaten) engineered by SAACKE GmbH.
These modules are specifically designed to supervise, control, and execute safe startup and shutdown sequences for complex multi-fuel, oil, and gas burners.
Operating in highly critical thermal environments, the F-GDSA-1 and F-GDSA-2 configurations handle automated pre-purging, ignition trail verification, and safe valve manipulation.
While the F-GDSA-1 functions as the primary safety logic solver for basic control loops, the F-GDSA-2 offers expanded hardware logic lines,
optimized safety timings, and multi-valve tracking to accommodate advanced modern boiler configurations on both land-based power plants and marine vessels.

Installation and Maintenance
Installation Guidelines
De-energize the Array: Disconnect all main high-voltage links ($230\text{ VAC}$) before working on or sliding the F-GDSA base units. Working on live wiring can permanently damage internal relays.
Isolate Signal Lines: Run low-voltage flame sensor wires in separate, shielded conduits away from heavy AC power cables or high-voltage spark ignition cables to avoid signal interference.
Ensure Proper Grounding: Ensure a low-resistance ea
