FAQ

Q: Does the 3S Intelligent Dual-Pump Controller have an anti-rust function?

A: Certainly, this is another classic design feature of the 3S water pump controller. Especially in drainage and sewage applications, pumps often rust due to long periods of inactivity, and the cost of replacing or repairing pumps is very high. From the initial design of the controller, 3S took this concern into consideration. Compared to other controllers on the market, it includes an anti-rust function. The automatic anti-rust parameters are already set at the factory, but they can also be manually adjusted for the anti-rust cycle. The pump will start for 2-3 seconds according to the set cycle, preventing rust and impeller blockage, significantly reducing costs.

Q: What are the features and functions of a 3S Intelligent Dual-Pump Controller used for sewage drainage?

A: Typically, the 3S Intelligent Dual-Pump Controller can be connected to liquid probe or float balls. When using liquid probe, connect them with 5 signal wires (low level, medium level, high level, super-high level, overflow alarm level). For float balls, connecting one float ball activates one main pump and one standby pump; connecting two float balls enables dual-pump simultaneous start; connecting three float balls triggers an overflow alarm.
Alarm: The alarm will continue to sound until manually canceled by an operator or automatically cleared when the high-level float ball moves down.
During drainage, when the water level reaches the super-high level, both pumps will automatically start simultaneously; when the low-level float ball moves down, indicating the end of drainage, both pumps will stop at the same time.

Q: What are the default settings for the parameters of the 3S Intelligent Dual-Pump Controller?

A: Operating time 30 minutes, stop time 60 minutes, anti-rust time 900 minutes, and no-load restart time 30 minutes.
