1. Fault 1: the actuator does not operate, but the power supply and signal lamp of the control module are on.
Treatment: check whether the power voltage is correct; Whether the motor is disconnected; Whether the 10-core plug is disconnected from end to end of each line; Whether the electric motor, potentiometer and capacitor are all well connected; The control module is judged by the method of contrast exchange.
2. Failure 2: the actuator does not operate, and the power lamp is on while the signal lamp is not on.
Processing method: check whether the polarity of input signal is correct; The control module is judged by the method of contrast exchange.
3. Failure 3: frequent oscillation of actuator due to improper adjustment of system parameters.
Treatment: the parameter setting of the regulator is not suitable, which will cause the system to produce different degree of oscillation. For single-loop control system, the system oscillation may occur due to too small scale band, too short integration time, too much differential time and differential gain. These parameters can be reasonably selected by the method of system setting to keep the stable speed of the loop.
4. Fault 4: the motor of the actuator is rapidly heating, crawling with shock and stopping action within a short time.
Processing method: whether the input end of ac 2V voltage control module is ac interference or not; Check whether the signal line is isolated from the power line; Whether the wiring of potentiometer and potentiometer is good; Feedback component action is normal.
5. Fault v: the actuator moves in steps, crawls and slowly.
Processing method: check whether the signal action time from the operator is correct.
6. Fault 6: the position feedback signal of the actuator is too large or too small.
Treatment: check whether the "zero" and "stroke" potentiometer adjustment is correct; Replace control module judgment.
7. Fault 7: when the signal is added, the actuator is on or off completely, and the limit switch is not stopped.
Treatment: check whether the function selection switch of the control module is in the correct position; Whether the adjustment of "zero" and "stroke" potentiometer is correct; Replace control module judgment.
8. Fault 8: the actuator vibrates and beeps.
Processing method: mainly because sensitivity adjusted too high, not sensitive area is too small, too sensitive, the actuator small oscillation circuit cannot be stable, can reduce the sensitivity counterclockwise fine-tuning potentiometer sensitivity; The fluid pressure is changing too much and the actuator is not pushing enough. Control valve selection large, valve often in small opening work.
9. Failure ix: the actuator is not operating normally, but the motor will not stop after the limit switch is operating.
Treatment: check whether there is any fault in the distribution line of limit switch and limit switch; Replace control module judgment.
10. Fault 10: the actuator belt is broken.
Treatment: check whether the internal drive part of the actuator is damaged and stuck. Whether the adjustment of "zero" and "stroke" potentiometer is correct; Whether the limit switch is correct.
Treatment: check whether the power voltage is correct; Whether the motor is disconnected; Whether the 10-core plug is disconnected from end to end of each line; Whether the electric motor, potentiometer and capacitor are all well connected; The control module is judged by the method of contrast exchange.
