1. Functional characteristics

A. Reliable magnetic conduction knob is used for local operation, and the traditional through knob design or waterproof rubber button design is abandoned, ensuring the waterproof performance and durability of the equipment and meeting the conditions for outdoor application.

B. Multi function display window, with rich display contents, the user can grasp the basic setting parameters and operation status of the equipment at any time, and the fault alarm information is clear at a glance.

C. Automatic phase detection and correction of three-phase power supply, on-site installation does not need to care about the phase sequence, thus avoiding the problem of equipment damage caused by installation. Automatic protection against phase failure to protect equipment.

D. It has complete fault detection functions such as locked rotor and oscillation judgment. After the equipment detects a fault, it will stop working to protect the equipment and the entire system, and display fault information through the display screen. Built in four passive contacts are used to output the valve open in place, the valve closed in place, the comprehensive fault, and the control mode (on-site/remote).

E. A variety of working modes can be set on site: positive and negative action modes can be set, and full open, stop, and full close action modes of valves can be set when the control signal is interrupted.

F. Instantaneous reverse protection. For example, when the valve opening action is being executed, the actuator will stop the action after receiving the valve closing command, and then execute the valve closing action after delaying a preset time to reduce the impact on the equipment.

G. The compound type can use a switching value signal to switch the control mode (automatic/manual), which is convenient for users to realize remote automatic/manual control.

1. The locked rotor can be removed in the opposite direction remotely without power failure or on-site operation.

2. Technical parameters
