Pumping systems requiring an alternative power connection can be configured with a generator changeover option. This single-phase 230Vac dual-pump panel incorporates a generator input socket and a manual changeover switch alongside standard automated pump control functions.
The controller manages two single-phase pump outputs with automatic duty alternation on start and after 30 minutes of continuous running, or after 6 hours in recirculation mode. When the standby start input closes, the second pump starts to assist. A 3-second staggered start delay prevents simultaneous pump starts to reduce electrical current draw and water surge. Independent electronic current sensing provides motor overload protection across selectable 0.1–6A and 5–16A ranges.
The panel features a dual-pump capacitive touch keypad with indicator lights for power, system enable, level alarms, pump auto/manual modes, pump run, and fault codes. An integrated visual strobe and audible buzzer with smart chirp silencing provide local fault notifications. Configurable DIP switches support Level Control mode with up to 5 float switches or Pressure Control mode with up to 3 pressure switches.
Housed in a 400 x 400 x 200 mm powder-coated mild steel enclosure with an inner door, the unit is IP56 rated for outdoor mounting. Hardware includes a padlockable mains isolator, individual pump circuit breakers, a removable gland plate, a volt-free BMS common fault output, and Modbus RTU Serial RS485 connections for SCADA.
