4. Installation and Disassembly
4.1 Allow valve electric device to be instaled at any position , but make sure the motor should be put as much horizontally as possible , the recommended installation method is to make the electric cabinet cap at horizontal position or vertical upward position , because such installation is helpful for grease , commissioning , maintenance and manual operation .

5. Matters need attention while connecting wires
5.1 Use hand wheel to open valve at 50% opening , press open or close valve button , check the rotation direction of valve to see if it is the same with the button , if not , immediately press stop button. Cut off the 3-phase powersupply , interchange any of the two phases of the 3-phase power supply .

6. Adjustment of torque control device
6.1 Regular type
6.1.1 Torque control device ( as shown in below picture 1): consists of crank , block , cam index plate , supporting plates and micro switch . When the output shaft was resisted by a certain torque , the worm will not only rotate , but also have an axial displacement , which will make the crank rotate and cause an angle displacement on the block , thus make it approaching the cam and make the supporting plates move upwards . When the torque on the output shaft has increased to a pre - set value , the supporting plates will move to a point to make the micro switch on and cut off the power supply , and then the motor will stop , this will be the control on the output torque of the electric device .

6.1.2 Adjustment of the torque control device : First adjust the off torque , starting from a small torque value , the value is gradualy increased until the valve is completely shut off . The adjustment of open / close direction

7.Adjustment of travel control device
7.1 Travel control device ( refer to above picture 2): consists of decimal gear , mandril , cam and micro switch , in short can be called as counter . It ’ s working mechanism is the drive pinion ( Z =8) inside the reduction gearbox will drive the counter to work . If the counter is adjusted to the valve open or close position , when the counter is rotated to the pre - set position ( turns ), the cam will be turned for 90°, and will press on the micro switch and make it work , cut off the power supply and the motor wil stop running , so as to control the travel ( turns ) of the electric device . For controlling valves with many turns , the cam can be turned for 180° or 270° while press on the micro switch and make it work .

7.2 Adjustment of travel control device : Shut off the valve completely . Dis - engage the travel control device , that is to use a screw driver to push the mandril of the travel control device and rotate for 90°, and make the drive pinion dis - engage with the digit pinion of the counter . Use the screw driver to rotate the “ close ” direction adjusting spindle , rotate as the arrow direction until the cam pressed on the spring bearer plate and make the micro switch response , then the “ close ” direction adjustment is preliminarily finished .

Release the mandril to make the drive pinion engage correctly with the digit pinions of both sides . To make them engage correctly , when the mandril is released , a screw driver should be used to rotate the adjusting spindle slightly at left and right direction , at this time the valve can be electric opened for several turns and then closed . Check whether the close direction travel is satisfactory , if not , please re - adjust as above procedure .

Close direction adjustment : After adjusting the close direction , open the valve manually to required position ( please pay atention during this period the travel control device cannot be disengaged , otherwise the close direction adjustment wil be a chaos ), then dis - engage the travel control device , rotate the " open ” direction adjusting spindle , rotate as the arrow direction until the cam pressed on the spring bearer plate and make the micro switch response , then engage the travel device and the drive pinion , then the “ open ” direction travel adjustment is finished . After adjusting the travel control device , the valve can be operated for several times . In general the valve open control is set at around 90%.

7.3 Adjustable open position indicator ( Picture 3): consists of reduction gears , adjusting pinion , valve open position scale , cam , micro switch and potentiometer . While adjusting at site , adjust the gear to required position based on the turns needed for corresponding valve , and engage with the gear of the reduction gear box ( the number of turns needed is indicated on the column ). When the valve is opening or closing , open position scale will indicate the open position.The indicating angle will be synchronized with the opening extent of the valve . This is used for long range transmission of the valve position .

7.5 Manual - Electric mode switch device ( Picture 4): This is half automatic switch . Switching from electric mode to manual mode will need to pull the changing shank , switching from manual mode to electric mode is performed automaticaly ( No need to pull the switching shank ). Switching from electric mode to manual mode is to pull the switching shank manualy , this makes the middle clutch of the output shaft move upward and press on the spring . When the shank was pulled to a certain position , the middle clutch will disengage the worm gear and engage with manual shaft jaw , this makes the force on the hand wheel is transmitted to the output shaft via . the middle clutch , this is the manual mode . Manual mode switching to electric mode is automaticaly made , when the motor rotates , it makes the worm gear rotates and the up - tight rod will fal down immediately , with the force of the spring the middle clutch will move toward the worm gear quickly and dis - engage the manual shaft , and then engage with the worm gear and this makes it in the electric mode.

8. Adjustment of Intelligent travel control device
Rotate the mode button ( red button ) to “ site ” position , use the hand wheel to make the valve at full stop position ( while reached the position , rotate backwards for 2circles), use the infrared setting tool to log on to the main menu :“ basic setting ", use the " up ” or “ down ” button to select “ close position setting ” and press " confirm ” to save the close position value. And then use the hand wheel to make the valve at ful open position ( while reached the position , rotate backwards for 2 circles ), enter the main menu :“ basic setting ", select “ open position setting ” and press “ confirm ” to save the open position value and log off.
