KT100/160J series AC cam controllerDetailed product description：

KT-100 and 160J AC cam controllers (referred to as controllers) are mainly used in lifting equipment to control the starting, stopping, speed regulation, and commutation of three-phase AC induction motors below 380 volts. It is also applicable to other electric drive devices with the same requirements.

Main technical data and model description
The main technical data is shown in Table 1

Rated current (A)	Ultimate Breaking Capacity (A)	Operating frequency	mechanical life	operating force
one hundred one hundred and sixty	4lH	600 times/hour	106 times	Less than 10 kilograms

Note: (1) The ultimate breaking capacity refers to 1. The ability under the condition of 1HU and COS Φ=0.65.
(2) The motor power that the controller can control should be selected based on the maximum breaking capacity.
(3) When the usage frequency exceeds the rated operating frequency, the capacity usage should be reduced (currently temporarily reduced to 60%).

Alternative explanation for KT100/160J series AC cam controller

1. The wiring schematic of this controller KT-100J/1, KT-100J, KT-100J, and 160J/5 is basically based on KTJ1-80/1, 2, and 5, so there is no need to change it when replacing.
2. When replacing KTJ1-80/3 with KT-100J/1, the connection between the controller and the resistor should be wired according to Figure 8.
3. The wiring schematic diagram of KT-160J/1 controller is a combination of KTJ-160/1 and KTJ2-150 schematic diagrams. When replacing KTJ1-150/1 with it, wiring according to the schematic diagram can provide an additional set of characteristics, so there is no need to change the wiring.
4. When replacing KTJ2-150 with KT-160J/1, a high-speed characteristic was observed, and the connection between the controller and resistor can be wired according to Figure 9.
5. When replacing KGJ1-100 (KT-3005) with KT-160J/1, wiring according to Figure 10 can completely maintain the original characteristic requirements. KGJ1-100 cannot select a 100 amp controller based on capacity as it is an 8-position device, and instead should choose a KT-160J/1 controller.

Structural Overview

The structure of the 100A and 160A controllers is the same, using cold extruded finger shaped copper contacts. The control circuit capacity and purpose vary (see circuit diagram for details).
The contact element of the controller is a rotating single break point structure, which is opened and closed by the changes in the concave and convex when the cam rotates. The positioning of each gear position is achieved through the cooperation of a positioning lever, a positioning ratchet, and a positioning spring.
The controller is made of protective type, with a steel plate outer cover, and the upper and lower bases are made of cast iron. The product structure is shown in Figure 1:

Table 2
1. The controller must be firmly installed on the bracket and cannot be suspended, that is, the lower base must be firmly attached to the ground or padded. There are four outlet holes on the lower base of the controller, and their dimensions are shown in Figure 1.
2. The basic wiring diagrams of each controller model are shown in Figures 3 to 7.

Usage and maintenance
After the controller is installed, it should be tested and operated normally before it can be put into use. Otherwise, the cause should be identified and the fault should be eliminated before testing.
The controller should be regularly inspected and maintained, and the melting spots on the contacts should be removed frequently with a file. Under the conditions of ensuring contact pressure and overtravel, the thickness of the contact after repair shall not be less than 4 millimeters. The contact pressure is 1.8-2.5 kilograms, which is equivalent to an overtravel of 3-5 millimeters at the contact and an opening distance of 8-13 millimeters.
The contact element equipped with an arc extinguishing cover is used for cutting resistors. If the arc is not large during use, the arc extinguishing cover can be used as a spare part for power contacts.
Regularly lubricate the rotating parts, replace damaged parts in a timely manner, and maintain tight connections.
The electrical connection must maintain sufficient pressure to prevent insulation damage caused by high temperature, especially paying attention to the pressure at the connection point of the soft connection on the insulation base.
