Position transmitter optional
LG-FB-4S (P-WZFK-4X) four linear position transmitter with the position of the potentiometer resistance 0.5KΩ ~ 1KΩ.
General debugging method
First, press the right is connected properly, adjust the following steps:
A. Measurement position transmitter ④ ⑤ terminals at both ends of the voltage absolute value with the open valve increases, the valve clearance is reduced (otherwise ③ ⑤ terminals indirect swap line), and to ensure that the absolute value of this voltage is less than 0.5V when fully closed
Two. Actuator action to the closed position, adjust the "low end" potentiometer, the output signal is 4mA.
3. Actuator action to the open position, adjust the "high end" potentiometer, the output signal is 20mA.
4. To the fully open and fully open position, the actuator action to see if the output is normal, if the error can repeat steps 1 to 3, if can not meet the requirements, the following steps to fine-tune.
Fine-tune the debug method
A. Measurement position transmitter ④ ⑤ terminals at both ends of the voltage absolute value with the open valve increases, the valve clearance is reduced (otherwise ③ ⑤ terminals indirect swap line), and to ensure that the absolute value of this voltage is less than 0.5V when fully closed
Two. Actuator action to the closed position, adjust the "low end" potentiometer, the test point voltage is less than 2mV, and then adjust the calibration potentiometer allows the output signal of 4mA.
3. Actuator action to the open position, adjust the "high end" potentiometer, the output signal is 20mA.
4. To the fully open and fully open position, the actuator action to see if the output is normal, if the error can repeat steps 1 to 3.
