The overall control electric actuator (hereinafter referred to as LK) is based on the 2SA3 switch type electric actuator.
The electrical control part, the LK type power control part, is made up of the mechanical transmission and electrical control.
It has the functions of field operation and remote operation and control, and it is very convenient for field debugging. It is suitable for each of the open loop control systems.
Type valves are operated and controlled by switching.
The electronic control part consists of the film key panel, the functional board, the opening module, the power supply, the plug-in board and the AC contactor.
The electronic control part is connected by the plug-in and the fastening bolt and the electric actuator, which can be easily disassembled or replaced, and also can be realized.
Control.
Two. The main technical parameters
Power supply: AC380V 50Hz three-phase three wire valve position signal: output 4 ~ 20mA (or 0 ~ 20mA) protection grade: IP67
Ambient temperature: -20 C ~ +60 C
Output power: 0.030 ~ 15kW
Three. Operation
LK can be operated in the "remote" or "in place" state respectively, and in the "far" form when the power is connected each time.
State, if you need to do "on the spot" operation, press the "on place" button and switch "far" state to "right"
"Ground" state, at this time, the green light emitting tube is extinguished by the "distant" state, and the red light emitting tube "on the spot" state is indicated.
The "open, close and stop" key of the remote operation does not work. It can only operate on the in-situ operation panel.
Stop "button".
In the process of opening the valve, the red light flashes and the green light is bright.
In the process of closing the valve, the green light flashes and the red light is bright.
The valve is in the "full open" position, the red light and the green light go out.
The valve is in the "off" position, the green light, red light.
After the "local" operation, the "far" button should be switched to the "remote" operation state.
The adjustment of electric actuators can be referred to "2SA3 multi turn electric actuator instruction manual"
