First, an overview 
 As the tear in the belt there, laid bare, at the junction of damage or sharp objects protruding belt, tearing switch provides an alarm signal to give the monitor or turn off the conveyor. 
 Tear switch installed in pairs on both sides of the belt, the air from the two vinyl jacket wire rope connected. Permanently fixed to one end of rope in the support bracket on the other end connected to the ring-pull switch on the tear. Two below the belt cord stroke in a closed loop, when the object or torn belt hanging down, one or two Saola cord, that is to detect the fault. Because the cord under the effect of the force, which the axial pull off the handle, pull out while filling up from the bounce, this time inside the two micro-quick off the alarm or turn off the conveyor. Troubleshooting from the sales will be down by the handle, is the camshaft reset the machine to be turned on. 

 Second, the characteristics 
 ? Structure is simple, solid, no maintenance. 
 ? With a coating of cast aluminum housing. 
 ? Heavy micro switch contacts. 
 ? Forces can trigger switch just 0.9kg. 
 Third, the technical parameters 
 ?-B type, two imported Omron micro-switches, 
 ? Shell dust, rain, suitable for indoor and outdoor installation; 
 ? A normally open, one normally closed, equipped with four-core cable, length 1.5m, wire colors red and blue for normally open, normally closed for the black and white; 
 ? Switch rated at 20A, 125,250 V or 480VAC. 
 ? Switch can be connected as required normally open or normally closed form. 
 Fourth, installation and commissioning 
 ? Tear switch is set to tape the next segment by the material between the buffer roller. 
 ? By switching on the mounting bracket and torn, torn to pull the switch and tape the edges with a high, if not high enough in the bracket with horns or under the channel, the measured height and then to stand with good bearing weld . 
 ? Stopped hanging cable: one end of the tear through the ring-pull switch with cord buttoned dead, the other end through the other side stand the middle of the hole torn switch stand. 
 ? Installed two switches and hung two ropes tear. Plus two 30-degree corner at the bar snaps cable, but the dead can not be deducted to activities. 
 ? The middle hole of the bracket to tighten both cable and then stopped dead cable buckle buckle. 
 ? Stopped the elastic cord: the general role of 0.9kg can trigger switch is appropriate. 
 ? Tape when the load sink to keep 5mm-10mm with the cable can be.
