　　安装与调试

　　·撕裂开关设置在受料段胶带下缓冲托辊之间按上安装支架和撕裂开关、撕 裂开关的拉环要与胶带边缘同高，若高度不够可在支架下加上垫铁或槽钢， 测好高度后再把支架与支座焊牢。 

　　·挂上拦索，一端穿过撕裂开关的拉环用索扣扣死，另一端穿过对方撕裂开 关支架中间的圆孔待用。安装好两只撕裂开关和挂两条拦索，再加30度弯角处把两条拦索扣在一起。

　　·收紧双方支架中间孔内的拦索然后扣死索扣。 

　　·拦索的松紧，一般作用在0.9Kg既可触发开关为宜。

　　·胶带在苛载下沉时要与缆绳保持5mm-10mm即可。

　　皮带撕裂开关\T3Z 068-22YR-2653-1由感知器和控制箱两大部分组成，感知器是纵向撕裂的检测元件，当运行中胶带撕裂时，感知器能可靠地检测出来，并输出一个开关量，控制箱接到感知器发出的信号，控制继电器动作，输出一个开关量给控制室实现自动紧急停机，同时面板告警指示闪烁，控制电路自锁，为使控制线路恢复常态，可按动面板上的复位安钮。此外面板上还装有自校按钮，当按下此钮时，可模拟撕裂故障，检验控制系统的工作

　　防撕裂开关由感知器和控制线路两部分组成。感知器是纵向撕裂的检测元件，当带式输送机输送带被异料穿透后，随着输送带运行带动异物使感知器受到挤压，或当溜槽出料口与输送带之间因物料堵塞而挤压布置在出料口的感知器时，感知器均能灵敏可靠的检测出输送带撕裂信号并输出开关量，发出停机信号。控制线路具有延时功能。

　　The belt tear switch \T3Z 068-22yr-2653-1 \220VAC is used to detect the longitudinal tear of belt conveyor belt, and the stop signal can be sent out in time to prevent the explosion of the belt.

　　Conditions of use

　　2. The environment temperature: - 35 ℃ - + 60 ℃

　　3. Relative humidity: no more than 95%.

　　4. Protection grade: IP65.

　　5. Power supply: AC220V 50Hz.

　　6. Number of output contacts: a set of conversion contacts.

　　7. Output contact capacity: AC220V 5A.

　　8. Insulation resistance: Ω 20 m or less

　　9. Insulation voltage: AC1000V test 1 minute.

　　Installation and debugging

　　, tear switch Settings between the buffer roller under the expected period of tape was according to the mounting bracket and tear on the switch, tear open a TAB is higher with tape edge, if high enough but under the support and cushion iron or steel channel, good height measurement again after the stent and bearing weld.

　　· hang up the rope, one end of the pull loop through the tear switch to use the cable QQ dead, the other end through the other side tear open the hole in the middle of the bracket to be used. Install two tear switches and hang two cables, and then add the two cables together at a 30 degree Angle.

　　· tighten the stop in the middle hole of the brackets of the two sides.

　　· the loosening of the rope is generally used to trigger the switch at 0.9kg.

　　· the tape should be kept at 5mm-10mm with the cable when it is sinking.

　　Belt tearing switch \ T3Z 068-22 yr - 2653-1 is composed of sensors and control box of two parts, the perceptron is longitudinal tear detecting element, when in the operation of the adhesive tape tearing, sensors can be reliably detected, and a switch output, control box received signal from the sensors, control relay action, output a switch to the control room and automatic emergency stop, panel alarm indicator flash at the same time, the control circuit self-locking, to restore normalcy to control circuit, can press reset knob on the panel. In addition, there is a self-calibration button on the panel. When this button is pressed, it can simulate the tear failure and check the work of the control system.

　　The tear - proof switch consists of a perceptron and a control circuit. Perceptron is longitudinal tear detecting element, when the conveyor belt conveyor is different material after penetration, with the conveyor belt running to drive foreign bodies make the perceptron is extruded, or when the chute discharging mouth and conveyor belt in a material jam for extrusion between the arrangement of the sensors in the discharging mouth, the sensors are sensitive and reliable to detect the conveyor belt tearing and switch output signal, signal downtime. The control circuit has the delay function.
