The Liberty PDCW-230 is a PDC-Series duplex control panel. It monitors and alternates two pumps up to 1 HP / 12A each — a primary float switch calls one pump per cycle, alternating between them for even wear, and an alarm float switch signals a high-water condition and calls the second pump if the first fails. Individual manual-reset fuses protect each pump, plug-in receptacles accept standard or right-angle plugs, and a programmed 6-hour run limiter shuts the pump off if it runs dry or the water level doesn't drop. It has green power and pump-run indicators, an audible/visual alarm with a 9-volt battery backup, auxiliary contacts, and 20A resettable breakers. Wired for single-phase power at 230V, in a NEMA 4X outdoor enclosure, with a 10' float switch cord.
