1、Common faults and troubleshooting methods.
| 故障 | 可能的原因 | 排除方法 |
|---|---|---|
| 执行器在初次启动时不会打开或关闭 | 1. 接线不正确 | 按照执行器的接线图核对接线是否正确？ |
| 2. 供电电源不正确 | 确认供电电源的输出电压为执行器额定电压的±10%，输出电流为执行器额定电流的3倍。 | |
| 3. SA未设置到1或3档 | 检查并将SA设置到1档或3档。 | |
| 4. 急停开关断开（针对配有急停功能的执行器） | 检查并接通急停开关。 | |
| 5. 输入信号超出范围 电流信号：4~20mA 电压信号：0~10V | 使用万用表测量控制模块P3和P4之间的电压，并核对电压是否在如下范围： 电流信号：0.88V~4.4V 电压信号：0V~10V |
|
| 6.全开全关设置到同一个位置。 | refer to (another document)《如何设置调节型电动阀门？》 Stroke Calibration 部分，正确设置全开/全关 位置。 | |
| 执行器在运行到目标位置之前，停止 | 1. 阀门卡滞 | 检查阀门是否存在卡滞，消除卡滞，并在执行器过载保护冷却后重试。 |
| 2. 流体介质中潜在的固体物导致阀门卡滞。 | 检查流体介质中是否存在固体物卡滞阀门的情况，消除阀门卡滞，并在执行器过载保护冷却后重试。 | |
| 3.全开或全关设置到中间位置，不正确。 | refer to (another document)《如何设置调节型电动阀门？》 Stroke Calibration 部分，正确设置全开/全关 位置。 | |
| 4.输入信号范围标定不正确。 | refer to (another document)《如何设置调节型电动阀门？》 输入信号标定 部分，正确标定输入信号范围。 | |
| 使用手柄，无法转动执行器 | 1. 流体介质中潜在的固体物导致阀门卡死。 | 检查流体介质中是否存在固体物卡滞阀门的情况，消除阀门卡滞，并在执行器过载保护冷却后重试。 |
| 2. 阀门卡死 | 检查阀门是否存在卡滞，消除卡滞，并在执行器过载保护冷却后重试。 | |
| 3. 执行器减速机构损坏。 | 从阀门上拆下执行器，转动手柄。如果不能转动，使用新的执行器更换。 | |
| 反馈信号不正确 | 1. 线路开路 | 用万用表测量控制模块P5和P6之间的电压，如果测量值>18V，说明信号开路。检查并修复线路问题。 |
| 2. 反馈信号接收端的输入阻抗过大。 | 测量并确认反馈信号接收端的输入阻抗<800欧姆 | |
| 3. 反馈信号标定错误。 | 1参照《如何设置调节型电动阀门》 Output Current Correction 部分，校准输出信号。 |
2、Please check whether the application working condition meets the parameter requirements.
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 larger 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 switching actuators have an IP67 weatherproof rating. Generally suitable for indoor or outdoor applications. Provides a degree of protection against rain and splashing water. Protecting the actuator from rain, snow, ice, and UV (sunlight) usually 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:The DCL switching actuator has an energization duration rate of 70% (42 seconds of operation per minute and must be turned off for 18 seconds), exceeding the 70% energization duration rate will cause the motor to go into overheat protection.
3、Check whether the wiring of the actuator is correct or not
Type E: with servo controller (regulated)
Input: 4~20mA / 0~10V Any configuration.
Output: 4~20mA / 0~10V Any configuration.

Wiring Instructions:
1. "N" of the "Power" input is connected to the center line, and "L" is connected to the phase line;
2, "Input signal" end connects to the negative pole of the input signal, "+" connects to the positive pole of the input signal;
The "output signal" end is connected to the negative terminal of the DC ammeter, and the "+" is connected to the positive terminal of the DC ammeter.
