KTJ1-50/1, KTJ1-80/1 and the KTJ1-80/3 controller serves as the transformation three-phase to wind thread the type asynchronous motor the stator and the rotor return route (see Figure 2, chart 3, chart 4).
When controller work in circuit diagram first position, the electric motor stator winding turns on the network, this time in the rotor return route has the completely starting resistance, in following all
levels of in order all levels of starting resistance pipe nipple. The electric motor commutation is the handwheel to the opposite one side, causes the stator to circle anti- trades meets the foreword but
to achieve. The electric motor separates after the network, it stops and appliesthe brake to use electricity the brake which the magnet holds moves to complete frequently. The electro-magnet connects in parallel fashion in the electric motor stator winding attachment. The controller control loop contact is uses for to achieve loses presses the interconnection and the travelling schedule limit protection.
The KTJ1-50/2 controller three-phase serves as the transformation to wind thread the type induction motor the rotor return route, the stator return route then transforms in addition by the contact device (see Figure 5) the KTJ1-50/5 controller to be possible to use in at the same time three-phase transforming two to wind thread the type induction motor (to see Figure 6).
The KTJ-50/3 controller took the transformation three-phase mouse cage type asynchronous motor in the stator return route with (see Figure 7), this controller serves as the control not to need the adjustable
speed and the torque electric motor.
In order to determine time controller each position and each kind of load electric motor speed, when 10, chart 11 and chart 12 special curves, in chart x-coordinate axis by full load carries the rectangular percentage to indicate, axis of ordinates by synchronous speed percentage expression.

    The controller makes the protected type, namely taking advantage of the shell which may unload by prevented touches the charged part.                                                                                                            The controller (see Figure 13) in the shell is loaded with the cam part (2), it is composed by the contact and the moving contact. The cam part installs in the angle steel (5) on, insulates the support (6) to install the static contact (10) and lugs (11), the moving contact release lever (7) an end installs the moving contact (8), as soon as installs the roller in addition (9), in the shell also has the cam drum which (4) and the axis (3) constitutes by the cam.
The analysis and synthesis rotor electric circuit or the stator electric circuit cam part contact partially (13) is separated with the eternit arc room it, these arc rooms are installed in the axis (12) on, the KTJ1 series controller control line cam part and the power circuit cam part except KTJ1-50/5, KTJ-80/1, outside KTJ-80/3 other is all same.
Wants to cause the cam drum to stop in the position which needs, then depends on the detent mechanism to carry out, the deciding organization turn (14) the locator (15) and the spring (16) is composed by the localization.
The operation control is taking advantage of with the cam drum association in the same place handwheel, the lead-in conductor the base hole penetrates after the controller under.
The controller may fix in the wall, the bracket and so on in any position, it has the special-purpose hole which the installment uses, on the body has the special-purpose bolt which the earth uses, the handwheel through the cam ring but earths.
When rotates the handwheel, under raised wheel-pressure roller, but causes the release lever rotation, installs on the release lever the moving contact also along with it rotation.
The continuation rotation release lever then the contact separates.
The pass gathers the contact to rotate the handwheel by the opposite order but to carry on it, after the cam leaves the roller, the spring returns to the mast top the home position.
The moving contact namely exceeds the quota the travelling schedule to the release lever rotation for the contact, its function wears for the contact when guaranteed between the contact still has must pressure.

build in and maintenance
    In front of starting hoist crane organization, must inspect the controller, the electric motor, the resistor, controls the cabinet limit switch and the brake magnet joint whether correct, must inspect the controller earth the reliability, then above the elimination dust, with does the cleaning rag to scratch the clean surface, the possible speech to blow only it with the compressed air, after clean carefully joins the power source to carry on the starting, and verifies its reason, whether inspects the line to apply the brake the situation and
the organization card stumbles and so on, after has inspected the organization revolution direction and the controller rotation direction is accurate, again experiments the organization in the load situation.

Elevating mechanism either translation organization electric motor in controller rise or drop (to front or to after) when first position namely starts, when the controller changes to the second position, the organization movement should start.

The electric motor starts to revolve to the speed achieved stable after, the controller only then trades to the next position, also is probably passes through 1 second time, when transits from a position to another position, the surge current should not surpass the biggest relay the working current, like wants to stop the electric motor being supposed to return the controller to the zero position in.

When uses in the synchronized speed descends the serious load, in the controller final position may obtain the minimum speed, is lifting heavily carries a load and similarly also needs with the level migration steadily to stop the electrically operated machine-hour, may transform the controller to the first position (does not change to 0) to apply the brake. When shoulders approaches in the full load the electric motor to stop, but if tallies very slightly, the electric motor speed descends to correspondingly in the first position £¦#118alue,
shoulders is not bigger than time in order to finally stops, the controller must transform to the zero position, when the electric motor is motionless, may not pause the controller is transforming the position. Periodic inspection each week should not be short in, when frequent work the controller needs to inspect frequently, must cause the controller work to be normal must observe the following request:                                        1st, maintains frequently in the roller and on the locator axis at book level lubricant, the lubricant may use the lubricating oil, will lack the lubricant to cause their very quick attrition.
2nd, the contact active face should not have the very big fever melt and weld the melting point. Burns the melt the place application fine file repair, but does not permit with the emery or the tissue paper, because on the emery or the paper the granulated substance material can insert in the copper but to cause the contact because to contact not not good because has the heat, after the file the contact surface should have the pit, at the same time the contact contact must be accurate, the line of contact is long must not be smaller than the contact width 75%. When non- necessity does not have the file contact, even if its surface has arc mark black smoke and so on, also may not the file, because it can reduce the contact the life. Should pay attention to the soft joint specially the situation, like rupture, electric current on process release lever and main spring,
thus creates the superior warm all cams part the damage.
3rd, all screw joint must be tight, starts when the use should inspect connects completely whether is tight, later main inspection wire linking with contact firm.
4th, must in the regular elimination controller dust and the soil, the dust easiest to use compressed air blows, the soil may use to soak the gasoline the cleaning rag to scratch, but the insulation surface must use to do the cleaning rag to scratch, the preventive repair, mainly lies in the prompt replacement already the components which is bad, in takes down the shell replaces in front of the old components, should
first meet controls in the cabinet the knife switch. Replaces the static contact is not difficult, must replace the control circuit the moving contact then also must take down the contact spring, the replacement may carry on according to the below procedure:Takes down insulation on first the joint busbar;

• Rotates that cam part which the raised rotor drum causes to need to replace to touch the first obstacle to gather (even if roller falls cam depression);
• Twists off on the angle iron stand firmly in the cam part nut;
• About swings the cam part and turns on the contact with the hand discretely to take out it.

    If the cam depression is very short, the part cannot take, then first takes down the neighbor temporarily the cam part, then upward or moves after under takes out. Replaces complete or the majority of moving
contacts regarding at the same time best takes down in advance has separates the arc board the axis (regarding to separate arc board to say), its step takes down its retaining spring first and twists off
fastens the nut, then carries on replaces the contact but not to need again to take down the cam part, wants to replace the axis serving tray cam or a wheel, then must drive the shell area from the controller to take out the cam drum, the replacement may carry on according to the following procedure.

• Takes down the locator the spring and pushes to the release lever terminus the support;
• Separates all contacts, may between the contact the pad by the depth 20-25 millimeter log;
• Twists off the firm bearing the bolt;
• Discretely upward takes out the cam drum.

    Replacement cam or localization when turn knocks in the axle collar first the stop ring, takes down the axle collar, takes out the split pin from the nut, squeezes out the nut then to carry on the replacement¡£
Like wants disassembles when the controller to have to pull open first controls in the cabinet the knife switch and twists off the joint wire, then from installs in the position to take down. The disassemblage step carries on according to the following order:

• Takes down the shell;
• Takes down from the cam part joins the tire£»
• Takes down the locator the spring;
• Takes the bottom camber board the axis and disassembles it;
• Takes down the cam part and disassembles it£»
• Takes down the handwheel from the cam drum axis£»
• Takes down the top roll serving tray;
• Takes down the top roll serving tray;
• Takes down the locator and disassembles it;
• Takes out the lower shaft serving tray.

    Assembles the controller according to the opposite order, carries on installs the timing to be supposed to pay attention to the following each spot specially:

• Should screw tight all screw bolt and nut£»
• The original nut and the gasket may not lack;
• Any form mechanical card stumbles, like the contact and the shell spring to separate the arc board, the roller countershaft and the release lever, the release lever and so on all is does not permit to
  insulation.
• The cam part and the locator roller axis axis serving tray as well as the cam working surface must spread the lubricant;
• The cam should fasten but does not have on the axis the displacement, after the cam drum axial verticality permits 1 millimeter;
• On the controller axis handwheel does not allow to have swings;
• The cam part contact should become the line contact, also the line of contact many in the contact width 75%, the sound of something astir contact middle line displacement permits 1 millimeter£»
• Allows the release lever (in cam part) to have the migration but to be supposed to cause the sound of something astir contact middle line the displacement not to surpass 1 millimeter;
• Inspects the contact to exceed the quota the travelling schedule whether conforms to table 1 inspection.

  The contact first obstacle gathers the order table and the controller installation diagram carries on the inspection.

When ordering must explain that:

• Controller pattern£»
• Taiwan number
