Check the calibration steps of electric regulating pneumatic valve

electric regulating pneumatic valve actuator is mainly composed of motor, reducer, position transmitter, etc, is an important execution units in industrial automation process control instrumentation. Position locator: unit or accept mediation from computer analog signals and position feedback signal after a comprehensive comparison of amplification of a multi-function power amplifier.

debugging steps:. Check the electricity.
. Put the little switch in manual mode.
. Direction of the school, the whole trip. Switch operation, should be open to the light, forming open switch after the motor should be stopped. And closed operation, should shut the light, open the switch after the motor should be stopped. If this is not the case, the switch will work with. If the motor switch direction inconsistent with hand direction, will feedback potentiometer and switch.
. Manual switch actuator to shut in the direction of running, the turn off the lights. Open close the trip contact was stopped, conductive plastic rotating locator for mA make feedback current.
. Manual switch makes the actuator to the direction of running, open the light at this time. Open schedule after contact is stopped up, adjust % potentiometer made feedback current mA. General time again and again.
. Switch in the automatic state, input - at the, end MA, respectively in,,,,, the input signal, the observation accuracy of adjustment. If there is a shock, and the dead zone potentiometer to increase the dead zone. （ Increase clockwise dead zone)
. Observe whether electric braking function and no idle away altogether.
. After torque switch, the motor should be stopped, and the opposite direction after the operation to remove the lock.
general factory actuator by stroke. Site for the travel terminals of the module and; With; With. At the same time.
