1、 Startup method

Star Triangle Voltage Reduction Start Control Cabinet: Suitable for control equipment with water pump power less than 15KW --90KW, starting with voltage reduction.

2、 Control method

Liquid level control Y: This control cabinet should be equipped with a high-performance float switch, which automatically controls the start and stop of the water pump in the water supply and drainage system according to the changes in liquid level.

Pressure control P: an external electrical contact pressure gauge or pressure transmitter that can automatically start and stop according to changes in pipeline pressure. This control device is widely used in domestic water supply and fire pressure boosting systems.

Temperature control T: External temperature sensor controls the start and stop of the pump according to the set temperature range. Widely used in temperature control applications such as constant temperature and heat exchange systems.

Fire Control X: This control cabinet is divided into two types: fire hydrant control and sprinkler control, and is equipped with fire protection equipment

Remote control of the heart's contact signal (used for linkage start/stop control), including operation (passive electrical contact), shutdown (passive electrical contact), fault signal (passive electrical contact), and also provides DC24V relay for firefighting

Heart start/stop using.
