   Power factor: 0.05

4. overall dimension and installation dimension
   （1）The controller contour and installs the size to see the chart, chart
   （2）The contact part binding post screw, the auxiliary circuit is M5, the  main circuit is M6.

   Chart 2  KTJ15-63/32L cam controller installment and external dimensions
5. usual service conditions
   1、Surrounding air temperature
   （1）Periphery the most upper air was mad the temperature does not surpass +40 ℃.
   （2）The surrounding air temperature lower limit is not lower than -5 ℃.
   （3）24 hour in mean ＆#118alue, does not surpass +35 ℃.
   Note: When uses in -10 ℃ or -25 ℃, the user should in the ordering when indicates.
   2、Altitude above sea level
   The installation site altitude above sea level, does not surpass 2,000  meters.
   3、Atmospheric condition
   The atmospheric relative humidity, is +40 ℃ is does not surpass 50%  in the periphery maximum temperature, in compares under the low temperature to be possible to have the high relative temperature; When the wettest month monthly mean temperature is 25 ℃, it maximum relative humidity is 90% equally, and considers to on the product surface which because the temperature change occurs to congeal the dew.
   4、The pollution rank    pollution rank is 3 levels
   5、Installs the category   to install the category to divide III kind
   Note: When every surpasses the above condition use, should by supply and demand both sides take specially orders the agreement solution.
6. Structure outline
       The KTJ15 series exchange cam controller, the protection rank is IP10, uses the vertical installment.
   The cam controller divides three 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 misoperation, 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.
   On the organization transmission partial packing body, the vertical operation handle is after the bevel drive cam shaft. The level control handle then is the through drive cam shaft, causes the contact group
   according to the stipulated procedure analysis and synthesis. The controller cam shaft is the vertical installment. The transmission partial 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 but obtains the good resistance to wear after the suitable heat treatment. Notch wheel overshooting has six index holes.
   The set screw loads in the position different hole, then decides the control handle the files figure. 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 in the permission scope.
   The cam for the black phenol aldehyde injection material, its structure is a jack-in type. Like this not only had guaranteed the rigging position is accurate, when like wants transforms the contact analysis and synthesis procedure, may conveniently take down the free cam, does not will certainly to put in order the Taiwan product to open greatly unloads greatly. Contact group structure for rotation type double break point. 32A and the 63A contact group installs the size same, installs the supporting plate to be general.
   The seat-s on a plane uses presses the cast-aluminium, 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 using of the line and the service.
   
7. use and servicing
   （1）Cam controller application installment screw retention. Should make an effort under to the vertical handle the handle lever insertion steering wheel hole in to push, decides the zip fastener then to be
   able automatically to lock in, then then operates.

   （2）According to the electric appliance schematic diagram request, the distinction then files operation control, observes the contact the analysis and synthesis whether the contact analysis and synthesis
   procedure does tally with the wiring diagram in, like does not have the symbol, should give to adjust or the replacement cam piece.

   （3）Must inspect the electric motor in front of the circular telegram with the resistor related electrical system wiring is whether correct, earths whether reliably.

   （4）After the circular telegram should according to the corresponding cam controller careful inspection electric motor movement situation, if has exceptionally, should the dump, after treat immediately verifies
   the reason only then to continue the circular telegram.

   （5）The controller should request according to below to inspect the service frequently;

   a、All bolts joint are partial must fasten, specially contact binding post screw；

   b、Rubs partially should maintain the certain lubrication frequently;

   c、The contact active face should not have the obvious melt spot, burns the melt the spot with the superfine file careful repair, does not permit use sanding.

   d、The damage components must promptly replace.
