The integral control type electric actuator (hereinafter referred to as LK) is based on the 2SA3 switch type electric actuator,
The electric control part is added, that is, the LK type power control part, and the mechanical drive and the electrical control are integrated into one,
It has the functions of field operation and remote operation control, and the field debugging is very convenient, which is applicable to the open-loop control system
Switch operation and control of class valves.
The electric control part is composed of a thin film key panel, a function board, an opening module, a power supply, a plug-in board and an alternating current contactor,
The electronic control part can be easily disassembled or replaced by the plug-in, the fastening bolt and the electric actuator, and the split body can also be realized
Control.
Two. Main technical parameters
Power supply: AC380V 50Hz three-phase three wire valve position signal: output 4 ~ 20mA (or 0 ~ 20mA) protection level: IP67
Ambient temperature: -20 ~ +60
Output power: 0.030 ~ 15kW
Three, operation
LK can operate separately in "remote" or "on the spot" state, and each time they are connected to power, they are in "remote" shape
If the "local" operation is needed, click the "on the spot" button and switch the "remote" state to "on"
At this time, the "green light tube" indicated by the "distant" state is extinguished, and the red light tube is indicated by the "in situ" state
Bright, remote operation of "on, off, stop" button does not work, only in the local operation panel on "open", "off",
Stop button.
In the process of opening the valve, the red light flashes and the green light is on;
In the process of closing the valve, the green light flashes and the red light is on;
The valve is in "full open" position. The red light is on and the green light is out;
The valve is in the "off" position, the green light, red light.
After the "local" operation, you should press the "remote" button to switch to "remote" operation state.
The adjustment of the electric actuator can refer to the instruction manual of 2SA3 multi turn electric actuator
