1、Common TroubleshootingMethods.

FaultPossible reasonsTroubleshooting Methods
Position feedback signal has no output1. Incorrect switch wiringCheck if the wiring is correct according to the wiring diagram of the actuator?
The actuator will not open or close during initial startup1. Incorrect wiringCheck if the wiring is correct according to the wiring diagram of the actuator?
The actuator can only be turned on or off1. Incorrect wiring1. Use a mechanical switch to measure the function of the actuator. If the actuator is running normally, check if the output logic of the control system meets expectations?
The actuator stops in the middle of the stroke1. Valve stuckCheck for valve sticking, eliminate sticking, and retry after actuator overload protection cooling.
2. Improper setting of fully open/fully closed camRefer to"How to set switch type electric valve"to correctly set the cam position.
2. Improper setting of fully open/fully closed camRefer to"How to set switch type electric valve"to correctly set the cam position.
2. Incorrect power supplyConfirm that the output voltage of the power supply is ± 10% of the rated voltage of the actuator, and the output current is 3 times the rated current of the actuator.
2. Potential solid substances in the fluid medium can cause valve jamming.Check if there is any solid object stuck in the valve in the fluid medium, eliminate the valve stuck, and retry after the actuator overload protection has cooled down.
2. Valve stuckCheck for valve sticking, eliminate sticking, and retry after actuator overload protection cooling.
3. Abnormal control switch or control relayMeasure the input voltage of the actuator switch control terminal with a multimeter to confirm if it meets expectations?
3. Improper setting of fully open/fully closed gear blockRefer to"How to set switch type electric valve"and correctly set the stop position.
3. Overcurrent causes damage to the position feedback signal switch.1. Refer to"How to set up a switch type electric valve", check if the fully open/fully closed cam presses the position feedback switch?
3. The actuator deceleration mechanism is damaged.Remove the actuator from the valve and turn the handle. If it cannot rotate, replace it with a new actuator.
4. Matching problem with control systemMeasure the function of the actuator using a mechanical switch. If the actuator is running normally, check if the output logic of the control system meets expectations?
5. Multiple actuators or actuators connected in parallel with other devicesThe switch type actuator is started through a starting capacitor, and parallel connection with other devices will affect the capacitance value of the starting capacitor. So, switch type actuators can only use single channel control and cannot be connected in parallel.
Using the handle, the actuator cannot be rotatedPotential solid substances in the fluid medium can cause valve jamming.Check if there is any solid object stuck in the valve in the fluid medium, eliminate the valve stuck, and retry after the actuator overload protection has cooled down.

2、Please check that the application conditions are in accordance with the parameters.

      Electric actuators can fail due to improper use or under the wrong application conditions. Long-term trouble-free operation of the actuator will be ensured under the application conditions defined in the product specification.

  • Supply voltage:The voltage of the power supply must be within the rated operating voltage of the actuator. Overvoltage or undervoltage may result in reduced actuator life.
  • Supply current:Since the starting current of the motor is much higher than the rated current. To ensure reliable operation of the actuator, use a power supply with an output current capacity more than three times the rated current of the actuator.
  • Temperature:Ensure that the actuator operates within the rated operating temperature range. Use of the actuator in environments outside of the rated operating temperature range may result in malfunction or reduced service life of the actuator, and ultimately, failure of the actuator.
  • Environment:DCL开关型执行机构具有IP67防风雨等级。一般适用于室内或室外应用。提供一定程度的防雨、防溅水。保护执行器免受雨淋,雪、冰和紫外线(阳光)Typically extends the life of the product. Very corrosive environments may cause premature failure of electronic equipment. Do not use non-explosion-proof series actuators in explosion-proof environments.
  • Energized persistence rate:DCL开关型执行器的通电持续率为70%(每分钟运行42秒,必须关闭18秒),超过70%of the energization duration rate will cause the motor to go into overheat protection.
