Where you’d find this
A pump house beacon flashes when a pump trips, so the night shift spots it from across the yard.
A steady lamp is easy to miss among other lights. A steady flash is the usual way to say: something needs you.
How it should behave
- Fault
- Fault ON means pump P-101 has tripped.
- Beacon
- While Fault is ON: 1 s on, 1 s off, starting on.
Press Run, then switch Fault ON in the Inputs tab and watch Beacon flash. Switch Fault OFF and it stops.
