The integrated control electric actuator (hereinafter referred to as LK) is based on the 2SA3 switching electric actuator.
The electric control part, LK power control part, is added, which integrates mechanical transmission and electrical control. It has the functions of field operation and remote operation control. It is very convenient to debug on site, and is suitable for switching and controlling all kinds of valves in open loop control system.
The electronic control part is composed of thin film key panel, function board, opening module, power supply and plug-in board and AC contactor.
The electronic control part is connected with the electric actuator through plug-in and fastening bolts, which can be easily disassembled or replaced, and can also be separated.
Control.
II. 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 be operated in "remote" or "on-site" state respectively. When the power supply is switched on, LK can be operated in "remote" state.
If you need to do "in-place" operation, click the "in-place" button to switch the "remote" state to "in-place".
In the "ground" state, the green light emitting tube indicated by the "remote" state is extinguished, and the red light emitting tube indicated by the "in-place" state is extinguished.
Bright, remote operation of the "on, off, stop" button does not work, can only operate in-situ operation panel "on, off, stop"
Stop button.
In the process of opening the valve, the red light flashes and the green light turns on.
In the process of closing the valve, the green light flashes and the red light turns on.
The valve is in the "full open" position. The red light is on and the green light is off.
The valve is in the "full shutdown" position. The green light is on and the red light is off.
After the "on-site" operation, you should press the "remote" button to switch to the "remote" operation state.
Adjustment of electric actuator can refer to "Instructions for the Use of 2SA3 Multi-Rotation Electric Actuator", the instruction number is
YXDZ-S-001, see electrical wiring diagram
