This weatherproof duplex panel features rugged NEMA 4X construction that withstands even the most severe weather conditions. It provide fully automatic operation for two pumps. They are a great option for basic pump operation, or for panels needing more options such as seal fail and/or high temp monitoring. These panels feature two (2) pump circuit breakers and two (2) adjustable motor overload protectors.

Superior quality duplex liquid-level controller, automatically controls alternation for two pump operation. High-level alarm warning designed for a variety of sump, effluent, sewage and water transfer applications.

Features:

• Rugged, NEMA 4X construction withstands even the most severe weather conditions and prevents corrosion.
• Provides fully automatic operation for two pumps. Alternates pump starting to distribute operating time. Provides extra pumping capacity in times of high inflow by energizing both pumps.
• Alternator selector toggle for maintenance on one or both pumps.
• NEMA 4X, 30 watt, flashing red light and alarm horn – 95db.
• NEMA 4X, fiberglass enclosure with gasketed, hinged door and stainless steel hardware.
• Entire unit is UL and CUL listed.
  
• Provides fully automatic operation for two pumps.
• Solid state pump alternator circuit displays float status for ease of installation and trouble shooting.
• Hinged door with lockable stainless steel latch for safe operation indoors or out.
• High-level alarm circuit includes through-door mounted silence switch for manual silence of alarm horn.
• Through-door mounted alarm test switch insures proper operation of the alarm circuit without the need to open the panel.
• Two through-door mounted pump run lights.
• Top-mounted high intensity flashing red light provides 360° visibility.
• Pulsating, corrosion proof alarm horn.
• These duplex controls are factory wired for operation with three float bulbs. An easy field modification for four float bulb operation using separate “lag-on” and “alarm bulbs” is provided.
• Alternator selector switch allows a choice of automatic alternation or operation of only pump 1 or pump 2. Typically used if one pump is down for maintenance.
• Lag pump-start delay built-in. Delays starting lag pump for 5 seconds if both pumps attempt to start simultaneously as after a power outage.
• Panel can be wired for a single power feed for pumps and control circuit or the control circuit can be wired to a separate power supply to insure alarm integrity in case of a tripped main breaker.
• Auxiliary alarm contacts provided for remote alarm connection.
• Color coded wiring, screw type terminals and plug in sockets, ensure ease of field servicing.
• Field wiring diagram, panel schematic and installation instructions included,
