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.

1. Quick killing of bismuth (quinclorac): It is reported that no crops can be planted except for rice within 309 days after the application of fast killing: no eggplant or tobacco can be planted within 12 months; tomatoes, carrots and umbrellas cannot be planted within 2 years. Shaped flower crops such as carrots, celery, parsley, etc. are sensitive to fast killing, and should be careful not to cause drifting phytotoxicity. You should not use the water that has been killed by quick killing to irrigate the above vegetables.
2. Sike (Metazine, oxalofenone): It is reported that the active ingredient per hectare is 420-1120 g, and after 4 months, alfalfa, asparagus, barley, corn, grasses, wheat, potato, red beans can be planted. Grass, tomato, sugar cane, soybean; rice, cotton, and peas can be grown after 8 months; other crops other than roots can be planted after 12 months; onions, beets and other root crops can be grown after 18 months. The recommended dosage in Heilongjiang Province is 210-560 grams per hectare, which is generally safe for the later crops. However, in dry areas, the soil organic matter content is low, and the alkaline soil with a pH greater than 7.5 may be used with high doses. After the beet is caused by phytotoxicity.
3. Guangshiling: It is reported that 560-1400 grams of active ingredient per hectare can be used to grow cotton, corn, cucurbitaceae (pumpkin, melon, cucumber, etc.) crops, kidney beans, peanuts, and 9 months after application in the southern United States. Peas, peppers, potatoes, rice, tobacco, transplanted tomatoes, sweet potatoes; any crop can be grown after 12 months. 9 months after application in the northern United States, corn, cotton, cucurbitaceae (pumpkin, melon, cucumber, etc.) crops, peas, peanuts, peppers, potatoes, rice, beets, sweet potatoes, tobacco, transplanted tomatoes; 12 months Tomato, wheat, and sweet potatoes can be grown later; all crops can be grown after 16 months. The recommended dosage in Heilongjiang Province is 480 grams per hectare. It is mixed with other chemicals and has no effect on the subsequent crops. Repeated spraying has only a slight effect on wheat. The leaves of wheat seedlings turn yellow and can be recovered in a short period without affecting yield.
Fourth, Pu Shite: a long-lasting herbicide. According to reports, 70 grams of active ingredient per hectare (1.4 liters of Puerte), wheat, rye, kidney beans, alfalfa and peas can be planted for 4 months after application; barley and tobacco can be planted after 9 and a half months; 18 After the month, corn (including corn seedling seedlings), cotton, lettuce, oats, potatoes, safflower, sweet corn, sorghum can be planted; beet can be grown after 40 months, and other crops can be planted after 26 months. Puschte degrades slowly in acidic soils and degrades rapidly in alkaline soils. In Heilongjiang Province, the pH value of less than 7 in the soil is 5% Puschte 1.5-2.0 liters per hectare, the west and northern regions can be planted in the first year after application of soybeans, wheat, corn growth may be inhibited, 1.8 liters per hectare The above corn has phytotoxicity. Soybeans, corn, and wheat can be planted in the first year after application in the southern and eastern regions; potatoes, cabbage, eggplant, pepper, green onion, tomato, watermelon, cantaloupe, and rapeseed can be planted 36 months after application; . Special attention should be paid to the use of poultry, vegetables, and rice breeding.
5. Bean huanglong (Dongcaolong, Bean): Similar to Pu Shite, it can not be used in soil with pH greater than 7. Bean huanglong with 5.6 grams of active ingredient per hectare, grain and grass forage can be planted 3 months after application; anti-bean huanglong corn can be planted after 6 months; scorpion, clover, cotton, cucumber can be planted after 9 months , corn, peas.
6. Broad grass clear: It degrades rapidly in alkaline soil and degrades slowly in acidic soil. The sensitive crops are sugar beet, rapeseed and cotton. If these three crops are planted, they must be separated by more than 2 years.

Effects of several herbicides on post-crop crops
The safety of herbicides on crops should include two aspects: the safety of the herbicides for the season crops and the safety of the crops. In recent years, certain herbicides have caused phytotoxicity to the later crops due to improper use, causing losses to production. The effects of several herbicides on post-crop crops are now described.
