The KTJ17 series AC cam controller (hereafter refers to as controller), is suitable in AC 50HZ, the voltage 380V  under respectively considered in the power circuit, uses in changing three-phase asynchronous, the electric motor stator electric circuit connection or the rotor electric circuit resistance £¦#118alue, comes the
positive governing electric motor the starting, the velocity modulation, to apply the brake or the commutation.

1.Classification: According to operating mode minute:

• Level rotation operation;
• The vertical reciprocation operates.

2¡¢Type And Meanings£º
 

   Surrounding air temperature: Periphery the most upper air was mad the temperature does not
surpass +40 ¡æ.  The surrounding air temperature lower limit is not lower than -5 ¡æ. 24 hour in mean £¦#118alue, does not surpass +35 ¡æ.
Note: When uses in -10 ¡æ or -25 ¡æ, the user should in the ordering when indicates.

• Altitude above sea level: The installation site altitude above sea level, does not surpass 2,000 meters.
• Atmospheric condition

   The atmospheric relative humidity, when the periphery maximum temperature is +40 ¡æ does not surpass 50%, in compares under the low temperature to be possible to have the high relative humidity: When at
the same time this month monthly mean lowest temperature is 25 ¡æ, the wettest month the maximum relative humidity is 90% equally, and considers to because the temperature change to occur on the product
surface congeals the dew.

• Pollution rank: The controller pollution rank is 3 levels.
• Installs the category: The controller installs the category is III  kind.

Note: When every surpasses the above condition use, should by supply and demand both sides take specially orders the agreement solution.

¡¡¡¡The controller protection rank is IP30, uses the vertical installment. The controller divides four parts: The control mechanism part, the cam and the contact systematic part and the shell are partial. Its control handle, for avoids because the hoist crane vibration and the accident collision causes the control mechanism movement, this handle has the zero position self-locking installment. When operation, only must press the handle, the zero position self-locking installment opens, then may operate.
The mechanical drive department loads separately on the box body, the vertical operation handle is after the bevel gear rotation cam shaft. The level operation handle then rotates the cam shaft directly, causes the contact group according to the stipulated procedure analysis and synthesis. The controller cam shaft is the vertical installment. Transmission road back minute various pivots use the rolling bearing, by reduces the friction force. Locates the notch wheel is but becomes by 3 millimeters steel plates ramming, and obtains the good resistance to wear after suitable heat treatment Wan Li. The controller files figure is six grades. In about each six grades of scopes. The files figure may choose wilfully. The localization ratchet spring strength is may adjust, like this may act according to the special details, under the classifying clear premise, adjusts the ratchet spring strength to cause the handle operation strength in the permission scope. Contact group structure for rotation type double break point. 32A and the 63A contact group installs the size to be same, therefore uses in common in installs the strut. The seat-s on a plane uses presses the cast-aluminium, on the kneading board uses the steel plate to stretch takes shape, the seat-s on a plane and the kneading board connect a body with 4 props, has the weight to be light, the rigidity good characteristic. Around the shell can facilitate dismantling, by supplies the installment, to match the line and the service uses.

1¡¢Handle operation strength: Is not bigger than 40N.
2¡¢Most controls files position: About and 6 grades.
3¡¢Most controls the way: KTJ7 is 21.
4¡¢The controller auxiliary contact group's electrical specification conforms to the master controller technical specification.
5¡¢The 32A controller may the positive governing 15 kilowatts and below winds thread the type electric motor.
6¡¢The 63A controller may the positive governing 30 kilowatts and below winds thread the type electric motor.
7¡¢The mechanical life is not lower than 1.5 million time.
8¡¢The cam controller main circuit passes breaks the ability to conform to the AC2 use category; The auxiliary circuit passes breaks the ability to be supposed to conform to the AC-15 use category, its
concrete £¦#118alue like table 1.

The controller main circuit electricity life should conform to the AC2 use category,The auxiliary circuit electricity life should conform to the ACC-15 use category,Its concrete £¦#118alue like table 2.       tables 2

7£®1The controller application installment screw retention, should the hemisphere raise after the vertical handle the handle lever under the
position to cause the self-locking organization to withdraw then
operates.
7£®2According to the electrical schematic diagram request, respectively is
by the files operation controller, observes the contact the analysis
and synthesis whether the contact healthy analysis and synthesis
procedure does tally with the wiring diagram in.
7£®3Must have the inspection electric motor in front of the circular
telegram with the resistor related electric system wiring is whether
correct, earths whether reliably.
7£®4After receives a telegram should according to the corresponding
controller careful inspection electric motor movement situation, if
has the difference to be supposed immediately the dump, after treats
verifies the reason only then to continue the circular telegram.
7£®5The controller should request according to below to inspect the
service frequently:
7£®5£®1All bolts joint are partial must have the fastening, specially contact
binding post screw;
7£®5£®2Rubs partially should maintain the certain lubrication frequently;
7£®5£®3Contact some surfaces should not have the obvious melt spot, burns the
melt the spot to be possible to use the smooth file careful repair,
does not permit the use sandpaper.
7£®5£®4The damage components must promptly replace.
