Use and maintenance
Note: This product has passed all-round debugging and inspection before leaving the factory
Product and valve installation, connection, may be due to valve couplings and other reasons, resulting in the valve can not be fully closed, fully open, need to re-adjust, adjust should follow the following steps:
1.Install and connect the actuator and the valve correctly;
2.Manual test run:
Remove the dust plug from the front cover, insert the attached handle into the hexagonal hole, turn the clockwise direction, the valve opening should be reduced, when the valve is in full close position, observe whether the turn-off Directional travel switch (switch action will be issued when the “Click”sound) and then turn the handle, check the machine.                If the stopper touches the adjusting screw; if the anticlockwise direction turns the handle, the valve opening should be increased. In the same way, check the opening direction stroke switch and the Mechanical Stopper, after manual operation, plug the dust plug.
3.Electric test run
Remove the wire cover and connect the wire correctly according to the circuit diagram
Power-on trial operation, pay attention to observe whether the actuator and valve are working properly.

一.Maintenance and upkeep
1.In view of this product structure close characteristic, specially has used the life long, the pressure resistance good high-grade Molybdenum base lubricating grease, therefore does not need to check and refuel;
2.Electric Valve for a long time without action or action rare, please regularly drive the actuator, check there is no abnormal belt.

二.Faults and countermeasures

Failure phenomenon	Why	Countermeasures
The Motor won’t run	It’s not plugged in	Plug it in
	The power supply voltage is incorrect or too low	Check the power supply voltage is normal
	Disconnection of wire, connection and terminal	Connect the wire and connect the fastening terminal normally
	Overheat Protector Action (ambient temperature is not too high, valve is not jammed)	Reduce Ambient temperature and check valve opening and closing by hand
		Reduce the frequency of use
		Overload
	The trip switch has been activated	Adjusting stroke baffle
	Damage of capacitor used in motor lead-in phase	Contact the manufacturer to replace the capacitor
	DC electric actuator diode open circuit	Contact the manufacturer to replace the diode
The switch indicator is not on	The pilot light’s out	Replace indicator light
	Poor action of travel switch	Change the stroke switch
The motor can not stop when it runs to the limit position	Poor action of travel switch	Change the stroke switch
	Source sequence three-phase electric power	Adjust three-phase electric power sequence
	Trip switch access control loop error	Adjusting wiring
	Mechanical Limit Ahead Electrical Limit Action	Re-adjust the Mechanical Stop Plate according to the adjustment instructions
	DC electric actuator diode open circuit	Contact the manufacturer to replace the diode
Actuator flooding	Breaking of TV Mirror	Please contact the manufacturer for maintenance
	The bolts, such as the upper cover, the inlet cover and the front cover, are not fastened and locked properly
	Non-standard incoming cable or not according to the specification at the entrance of the line for waterproof treatment
