Adjusting module debugging method
First, use the hand wheel of the actuator to move the electric valve to the middle position
Then turn on the power, and the power indicator light will light up. If The power supply is missing a phase, the phase missing indicator light is on
, and the forward and reverse effects of the pull-out switch cannot be valid at the same time.
, Position feedback signal adjustment during positive action. Turn the electric actuator to the fully closed position and determine the rotation direction of the potentiometer in the electrical installation. (When the potentiometer rotates in the direction of opening the valve, the voltage on the sliding contact of the potentiometer will increase. Otherwise, the potential sliding contact will be outside. Swap the two wires and engage the two gears, close the actuator in place, adjust the zero potentiometer so that the voltage of the two test points is less than 1, then adjust the potentiometer so that the position feedback signal is Adjust the potentiometer so that the feedback signal is: If you find that the output signal decreases when you rotate the above potentiometer clockwise, please interchange the lines on both sides of the valve position potentiometer. The output signal increases, otherwise it decreases.
In order to ensure the positioning accuracy of the electric actuator in automatic control, the sensitivity must be adjusted. The sensitivity is small and the positioning accuracy is high, but it is prone to oscillation. The sensitivity is large and it is not easy to oscillate, but The positioning accuracy is poor. The sensitivity potentiometer can be adjusted to choose between the two, so that it does not produce oscillation and is the best adjustment value
. After the input control signal is lost, the lost signal indicator light will light up.
After the valve and closing valve are locked in one direction, run in the other direction for seconds to unlock.
