PXA-02GKH-10-30/Introduction to deviation switch: The deviation switch is used to detect the deviation and twisting degree of the tape in the tape machine. It can prevent damage to the edge of the belt and material detachment caused by the deviation of the tape. It is a protective switch that achieves automatic alarm and shutdown. Technical parameters: Operating temperature: -40 ℃~+60 ℃, working pressure: 80~110kpa, electrical life switch action: 100000 times. Deviation switch function: The deviation switch FPKG-A00 is used to start the local switch and immediately stop the machine in case of an emergency accident on the tape conveyor site, to prevent the expansion of the accident. Due to its convenient installation and reliable switch operation, this machine has been applied on site in tape conveyors. Conventional belt conveyors, underground cable support belt conveyors, ship loading and unloading systems, stacker/reclaimer conveyors, inclined and shuttle conveyors, cranes, excavators, boom limiters, skirt feeders, and other types of conveyors used in metallurgy, coal, cement building materials, mining, power, port, metallurgy, chemical and other fields. The heavy-duty limit switch detects the deviation of the adhesive tape, which is a protective device for automatic alarm and shutdown of the adhesive tape machine control. Deviation switch function: When the running tape deviates, the edge of the tape drives the vertical stick to rotate and squeeze to tilt. If the tilt angle of the vertical stick is greater than the first level action angle, a set of switch signals will be generated by the switch. If the vertical stick continues to tilt more than the second level action angle, another set of switch signals will be output. Two sets of switch signals can be used for warning or shutdown, the tape machine can reset and operate normally, and the upright rod can automatically reset. Features: Simple and practical structure, performance: dust-proof, shockproof, moisture-proof. Small size, light weight, long service life. Easy installation, maintenance free. The output signal can be interlocked with on-site equipment or delivered to the microcomputer control system. Installation instructions: 1. There are 12mm holes on both sides of the base of the two-stage deviation switch. Drill 12mm holes on the iron frame next to the belt conveyor and tighten the deviation switch with M10 × 30mm screws. 2. The installation of the deviation switch should be carried out at a location where the conveying device is prone to deviation, referring to the process requirements of the application unit. At the same time, the effective distance and thrust between the belt and the blocking wheel should be considered. It is recommended to install the distance between the belt and the blocking wheel between 120-160mm. 3. Installation distance: It is recommended to install a pair of deviation switches every 50 meters. 4. The deviation switch is equipped with a 0.5 meter long four core rubber sleeve cable when it leaves the factory. The core wires are equipped with wire numbers 1, 2, 3, and 4, where 1 and 2 are normally open contacts that are first level alarm signals, and 3 and 4 are normally closed contacts that are second level shutdown signals< br/>
