STATION_FLOOD_DET
Dry-pit flood detection in three stages — sump seepage, floor water, upper flood — that runs the sump pump, trips the drives and latches the record.
When to use it
Use STATION_FLOOD_DET when a dry-pit or dry-well pump station has motors, drives and switchgear at floor level that must be de-energised before water reaches them, and a sump pump that handles normal seepage.

Supervised control write
STATION_FLOOD_DET commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
