General Failure and Maintenance Of Electric Actuator

Long-term use of electric actuators, there may happen following 3 issues: Motor Doesn’t Work, The Switch Indicator Doesn’t Work and The Angle Of The Switch Is Constantly Changing.

Failure Phenomenon	Failure Cause	Methods Of Resolution
Motor Doesn’t Work	No power	Connect the power
	Broken wire or the connector is disconnected from the terminal	Repair the broken wire, and connect the terminal correctly
	Wrong voltage	Check the voltage
	Overheat protector working(Working temperature too high)	Reduce the working environment temperature, use manual control to check whether the valve can be opened properly
	Poor action of limit switch	Change the switch
	Poor capacitance	Change teh capacitance
The Switch Indicator Doesn’t Work	Light Bulb is broken	Change the light bulb
	Poor action of limit switch	Change the switch
	Poor adjustment of the block	Adjust it again
The Angle Of The Switch Is Constantly Changing	There’s interference from the source	Check the signal again
	The voltage divider is causing interference	Change potentiometer
	The gears are loose	Check the gears and reinforce the screws on the gears
