Chinese menu 

 High-resolution dot matrix liquid crystal display, the large number of real-time display of the valve opening size to full Chinese menu display operation, and the work of real-time display of Chinese characters according to police information, working conditions; high-brightness LED LED indicates the valve open, closed limit position. 

 ◆ Free openings debugging 

 To set operating parameters, system status check can be set through the operation buttons or infrared device to complete, without opening the electrical enclosure, making the environment in the dust, moisture and other harmful substances can not enter inside the actuator, greatly improves the electrical control part of the reliability. 

 ◆ adaptive dead zone 

 In the "automatic distance control" mode, without setting adjustment dead zone, running automatic measurement system based on positioning accuracy and determine the best values ??of dead zone, to ensure the implementation runs without oscillation and high positioning accuracy. 

 ◆ wiring easy, fast 

 Actuators wiring uses a fast connection mode. External cable to plug, unplug the plug can be removed as long as the actuator. Plug is waterproof, which avoids the process of re-wiring and maintenance errors. 

 ◆ absolute encoder position sensor 

 Our intelligent straight stroke electric actuator optional absolute encoder position sensor that uses non-contact measurement with high accuracy and long life. 

 ◆ non-volatile status indication 

 Configurable bistable relay output contacts can indicate various states of the valve (including the limit switch, over-torque, operating instructions, or the valve opening to a location, etc.), even if the system is powered down but also to maintain output the status quo. 

 ◆ variety of control methods 

 1, on-site control 

 Through the "live" button to select "site control" mode, you can use in the field "Open" button, "off" button, or "IR set device" to control the valve open, close or stop. 

 2, the remote control switch (also known as remote manual control) 

 Switching control has three inputs, which means that the valve, closing valves, stop / hold; switch control can be achieved through external wiring "keep" or "jog" mode control. 

 3, the amount of current remote control (also known as the remote control) 

 Users can DC4 ~ 20mA electric current to control the operation of the actuator in order to achieve precise positioning of the valve. 

 4, two-wire control 

 Actuator with a two-wire electric operation functions. Can achieve "a letter open, non-gateway" and "gateway, no open letter" special control requirements. 



 ◆ Perfect protection 

 1, motor overload protection 

 Operation when the actuator motor stall occurs, the control system will stop the motor rotation. This feature not only protect the valve, but also to protect the actuator itself. 

 2, the valve position limit protection 

 Actuator runs to close the open limit position limit and stop automatically. 

 3, the instantaneous reversal protection 

 When the actuator moves in the opposite direction to accept the command, automatically add a time delay, to prevent the generation of the valve shaft and the transmission of unnecessary wear and tear. 

 4, motor overheat protection 

 End of the motor winding with thermal relay to directly detect the temperature of the motor windings. When the thermal relay winding overheating is detected, the control circuit prevents the device action. 

 5, the electrical isolation 

 Contact with the outside world actuator input and output channels are using optical isolation to ensure reliable operation of the actuator without interference. 

 ◆ brake function with electric brake 

 The electric brake actuator with brake function, which greatly improved the valve positioning accuracy. 

 ◆ high efficiency and low noise 

 Precision gear box, the gap is small, high efficiency, low noise (up to 50 dB), long life. 

 ◆ Electrical Characteristics 

 Configured according to the power requirements of single-phase totally enclosed squirrel cage induction motor, starting torque, small moment of inertia
