XLKT8Series master controller

1. Overview

This controller is used IEC Standard, there are AC, DC, encoder and non-contact and other forms of work. Can be connected to the encoder, the digital display and control. Structural simplicity, contact box through the fast speed, arc extinguishing effect, high electrical life. High precision, can be easily carried out 0.1Degree (or smaller) adjustment.

2. Use and classification -Used for limit, mechanical programming control

1, Adjustable master controller for AC 380VThe following; DC 220VIn the following, it is used to turn over and control the circuit frequently in the mechanical transmission device and realize the limit of program and sequence in the equipment such as turning steel, drawing steel, pushing steel, pressing, blast furnace feeding, oxygen lance lifting, , Positioning control purposes.
2, Non-contact controller is a proximity switch for switching components for industrial computers, PLC Control equipment, do signal switching control.

3. Model significance

4. Working conditions and installation conditions

Ambient air temperature and humidity
The temperature limit is +70Lt; 0 & gt; C~-25Lt; 0 & gt; C, 24Hour, the average value does not exceed +35Lt; 0 & gt; C; Monthly average maximum relative humidity does not exceed 90%, Allowing the temperature change occurs on the product surface condensation.
NOTE: For use in ambient air the lower limit is -25Lt; 0 & gt; CWhen the working conditions, the user should be stated when ordering.
Protection class is IP55; Pollution level is 3level.

5. Technical Parameters

10AThe breaking capacity of the controller contacts reaches AC AC-15, DC DC-13Of its electrical life exchange of not less than 100Million times, not less than DC 40The mechanical life of the controller is not less than 300Million times.

6. Adjustment and work process

Closed position adjustment
Cam pieces are marked with an angle on the circumference and are adjusted according to the closing procedure.
Operation method as shown
In the pre-adjustment, can also be fixed with a wrench to the camshaft, then use the wrench to rotate the cam to obtain the angle you need to close.
In the fine adjustment: the wrench hook the cam groove required direction, with the appropriate tool wrench hit, you can achieve 0.1Degrees below the accuracy

8. The use of contactless controllers
Work, first close to the switch connected by wiring diagram, and then start the system work.
(Note: detection should be with resistive load! Load can be relays, etc.)
The application wiring diagram is as follows:

9. Encoder type controller structure and principle
Encoder controller installed with the camshaft synchronous rotation of the encoder, to achieve both the switch output, but also the encoder output, to achieve the requirements of communication control.

10. Use and repair

use
XLKT8Series controller, with a foot, small size, light weight, installation is extremely convenient, in the replacement of old LK4Series master controller, no need to change the installation size and wheelbase, you can directly replace.

maintain
The controller is extremely easy to maintain; with the transmission device to be regular oiling. Contact box can be adjusted and disassembled, contact silver dot wear contact thickness of one-half, should replace the contact box. AC, DC. Proximity switch replacement should pay attention to the switch technical data to be the same, wiring should pay attention to polarity.

11. Ordering instructions

Order to be specified

· Master controller model; AC, DCZ); Contact, non-contact (J) .

· XLKT8-08 / 14, XLKT8-24 / 14, XLKT8-08 / 13, XLKT8-24 / 13The master controller must also specify the gearbox ratio.

· Selection of non-contact controller, should indicate the working voltage close to the switch AC220V , DC24V ; Normally open model or normally closed type; two-wire or three-wire or four-wire system.

· The choice of encoder type controller should give the encoder type appearance installation size

· When ordering, you can refer to the new and old models comparison table selection (see table3)

· In industry PC and PLC Controllers in controlled circuits, such as blast furnace feeding systems, tooling systems, converter tilting systems, master controllers used in oxygen lance lifting systems, should use non-contact controllers.

example: LK4-188 / 3Switch to use XLKT8-24 / 13Two - wire system master controller 24V, DC, the ratio 1: 16.65The factory to undertake a variety of non - standard master controller and provide various accessories.
