In industrial automation and flow control systems, multi turn electric actuators play a vital role in ensuring precise valve and damper operations. However, like any mechanical device, these actuators may occasionally encounter operational issues. Knowing how to troubleshoot these problems effectively can save significant time, reduce downtime, and maintain operational efficiency.
At FLOWINN, a global leader in electric actuator development, manufacturing, and service, we are committed to providing high-performance solutions that minimize risks and maximize uptime. Based on years of industry experience, here’s a comprehensive guide to troubleshooting common issues in multi turn electric actuators.
Common Issues in Multi Turn Electric Actuators
1. Failure to Start
One of the most frequent issues is the actuator not starting when a command is issued. Possible causes include:
Power supply problems
Faulty wiring connections
Internal motor failures
Troubleshooting Tip: First, check the power source to ensure correct voltage and phase. Next, inspect wiring for loose or damaged connections. If these are intact, motor testing may be necessary to determine internal faults.
2. Incomplete or Irregular Turns
When actuators fail to complete full turns or exhibit inconsistent operation, it often points to:
Limit switch misadjustment
Obstructed mechanical movement
Gear train wear or damage
Troubleshooting Tip: Inspect and reset the limit switches according to the manufacturer’s guidelines. Check for mechanical blockages in the actuator or valve and assess internal gears for visible wear.
3. Overheating
Continuous operation or overload conditions may lead to actuator overheating. This can eventually trigger thermal protection systems, causing unexpected shutdowns.
Troubleshooting Tip: Ensure that the actuator is operating within the rated duty cycle. Regular lubrication of moving parts and correct torque settings are crucial to avoid mechanical strain.
4. Unresponsive Remote Control
For actuators with remote control features, communication failures can disrupt operations. These issues typically involve:
Signal interference
Faulty control cards
Software bugs
Troubleshooting Tip: Confirm signal strength and integrity. Update software firmware if available, and replace any defective control boards after diagnosis.
