The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.

Citrus garden to prevent fertilizer damage
   　 The symptoms of citrus fertilizer appear within 10 to 60 days after fertilization. First, the water drops from the old tip of the branch to white or yellow, and then the coke falls. Then the new leaves on the top of the branch fall or the coke does not fall on the branches. Checking the dead branches with severe fertilizer damage, the main branches and side branches of the aboveground parts opposite to the fertilization site can be found, and severe rotten skin occurs. When the skin was scratched, the bark was brownish and the branches were dehydrated. Excavation observation, the "burlap root" in the fertilization site and the nearby topsoil is completely rotten, and the root bark of the fine root and the coarse transverse root is rotten and peeled, and extends to the root neck, the trunk and the main branch. The orange tree that survives the lighter degree of fatness is generally not able to be extracted from a new shoot. If the fat occurs in front of the flower, it cannot bloom.
   Cause fertilizer damage
   Fertilization is related to the type of fertilizer, the method of fertilization and the dryness and wetness of the soil in the orange orchard. Applying organic fertilizer or mixing fertilizer and soil fertilizer, the orange tree rarely suffers from fertilizer damage, while the single application of chemical fertilizer is prone to fat damage. The same is chemical fertilizer, ammonium chloride citrus is the most susceptible to fertilizer damage, followed by ammonium sulfate, urea, ammonia, ammonium bicarbonate, etc., the application of compound fertilizer and superphosphate is less harmful. Heavy dosage and improper fertilization methods are the main causes of citrus damage. The same amount of fertilization, dig hole dry application is more likely to cause fat damage than watering the ditch. Especially when the soil is dry, dig a hole and dry it. After the application, it will be sunny and rainy. Once it rains, the fertilizer may come more quickly and seriously.
   Measures to prevent fertilizer damage
   The citrus fertilizer should be dominated by soil organic fertilizer. The soil fertilizer can provide various nutrients for the orange tree, and can improve the soil structure, and the fertilizer efficiency is longer. Winter and spring base fertilizers are more suitable for cake fertilizer, bar fertilizer, garbage, river pond mud and human dung. After the soil is fertilized, the effect is better. If it is not piled and maturized, it should be used in the trenching line outside the canopy drip line. When using chemical fertilizers for top dressing, it must be applied with water, and avoid dry cooking when the soil is dry. The amount of fertilizer should not be too much, especially the nitrogen fertilizer should pay more attention to the application rate. The annual yield of 50 kg of orange trees, the amount of pure nitrogen applied per plant should not exceed 250 grams. Top dressing, the concentration of fertilizer can not exceed 0.5%.
   Fertilizer Emergency Treatment
After fertilization, when the old leaves of the base of the branches are peeled off, the soil in the fertilization part should be quickly opened, and the soil in the fertilization point should be washed with water to dilute the soil fertilizer concentration and cut off the rotten roots and cover the new soil. Scrape the root neck, the rotten skin of the main part, apply the bactericidal agent, prevent the spread of the plaque, and cut off the dead branches.
