5. 6, Pollution level
The pollution degree of the controller is 3level.
5. 7Installation category
The installation category for the controller is III level.
Note: Where beyond the above conditions, should be used by both supply and demand as a special order agreement settlement.

6. Structure overview
KTJ15A , BSeries of exchanges Cam controller Protection class is IP30, With vertical installation.
The controller is divided into four parts: the operating mechanism part, the cam and the contact system part and the shell part.The operating handle, in order to avoid because of the crane vibration and the accidental collision causes the operating mechanism malfunction, Just press down the handle and the zero lock will open.
The mechanical transmission part is mounted on the upper part of the box, the vertical operating handle is through the bevel gear drive camshaft, the horizontal operation handle is the direct drive camshaft, Installation KTJ15B-32/2, 63/2, 32/5, 63/5For the double row arrangement, the rest are single row.Private part of the fulcrum with rolling bearings, in order to reduce friction.
The positioning ratchet is made by 3Mm thick steel plate stamping, and after appropriate heat treatment to obtain good wear resistance. Controller stalls for five stalls in the left and right of the five stalls range, the number of stalls can be arbitrarily selected.Positioning ratchet spring force can be adjusted , So that according to specific circumstances, in the sub-file clear premise, adjusting the ratchet spring force to handle the handle in the allowable range.
Cam for the black phenolic molding and molding, the structure of the ventricle, so that the assembly position to ensure accuracy.
Contact group structure are rotating double break. 32Aversus 63AThe same size of the contact group installation, it is commonly used in the installation of pole. Die-cast aluminum frame, the upper panel using sheet metal forming, 4A pillar together into one, with a light weight, good stiffness characteristics, before and after the cover can be easily removed for installation, wiring and maintenance.

7. Use and maintenance 7. 1, The controller application installation screw fixed.Opposite to the handle handle rod into the operating hole in the hard push down, positioning lock will be able to automatically lock, and then you can operate.
7. 2In accordance with the requirements of the electrical schematic, respectively, by-file control controller to observe whether the separation and contact with the wiring diagram of the contact division and process in line.
7. 3Before energizing, check whether the wiring of the electrical system and the electric motor and the resistor are correct.
7. 4After the electricity should be careful to check the corresponding controller to run the motor, if any differences should be immediately cut off the power to be identified after the reasons to continue to power.
7. 5The controller should always be checked for repair as follows:
7. 5. 1All screw connections must be fastened, especially the contact terminal screws;
7. 5. 2Friction part should always maintain a certain degree of lubrication;
7. 5. 3Contact the work surface should be no obvious melting spot, burned parts can be fine with careful repair files, does not allow the use of sandpaper.
7. 5. 4Damaged parts should be replaced in time.
