The DXZ multifunctional travel limiter (referred to as the limiter) is a domestically designed and produced product imported from the French company POTEIN, and all performance indicators meet the technical requirements of the French company POTEIN's products. The DXZ multifunctional travel limiter can be widely used for controlling and limiting the spatial three coordinate of lifting and transmission machinery in industries such as construction, ports, and mining. It has the characteristics of small size, multiple functions, high accuracy, adjustable limit, strong universality, and easy maintenance, installation, and use adjustment. 1.2 Main technical parameters of DXZ multifunctional travel limiter

a、 working environment

Environmental temperature: 233-328K (-40--+55 ℃)

Relative humidity: not exceeding 90%

b、 Transmission ratio: 1:13--1:960

c、 Repetitive positioning accuracy:

The angle error of the memory cam is not greater than 0.005rad

d、 Rated voltage

AC：125—250V

DC：30V

e、 Rated current: 6A

f、 control loop

The standard design circuit consists of 1-4 circuits, which can be increased to 5-6 control circuits according to user needs

3. Installation and adjustment of DXZ multifunctional travel limiter

The memory cam and micro switch corresponding to the adjustment axis of the DXZ multifunctional travel limiter are:

1Z—1T—1WK； 2Z—2T—2WK； 3Z—3T—3WK； 4Z—4T—4WK；

DXZ multifunctional travel limiter adjustment program

a、 Remove the upper cover, check and tighten the 2-M3 × 55 screws.

b、 Loosen the M5 nut.

c、 As needed, turn the controlled mechanism to the designated position (empty load), and the corresponding micro switch that controls the action of the mechanism should switch instantly.

Namely: Adjust the corresponding adjustment axis (Z) to press down the micro switch (WK) contact of the memory cam (T).

d、 Tighten the M5 nut. The nut must be tightened, otherwise it will cause memory disorder.

e、 The institution should repeatedly run without load several times to verify the accuracy of the memory location. (Repeat the above adjustments if there are errors).

f、 Confirm that the location meets the requirements; Tighten the M5 nut and install the cover.

g、 After the institution operates normally, it should regularly check whether the memory control position has changed in order to make timely corrections.
