PPN-12-30 Waterproof and Explosion proof Runaway Switch PPN-12-30 Waterproof and Explosion proof Runaway Switch The basic principle of PPN-12-30 Waterproof and Explosion proof Runaway Switch is that when the conveyor belt deviates during operation, the conveyor belt touches the switch vertical roller and causes it to deflect. When the deviation angle of the vertical roller reaches level 1 switch angle, the switch sends an alarm signal. When the conveyor belt deviates seriously and reaches the second level switch angle, the switch sends a stop signal to automatically stop the conveyor belt due to deviation fault. When the deviation fault is eliminated and the tape machine is running normally, the switch vertical roller can automatically reset and return to the initial state. Installation and adjustment: 1. The deviation switch should be set on both sides of the conveyor belt, and the vertical rollers should be perpendicular to the edge plane of the conveyor belt, with both sides of the conveyor belt located at 1/3 of the height of the vertical rollers. The distance between the vertical roller of the deviation switch and the normal position of the conveyor belt should be 50-100mm. The number of deviation switches should be determined based on the length, type, and layout of the conveyor. Generally, it should be set at the head, tail, convex arc section, concave arc section, and in the middle position of the conveyor. (Note: When the conveyor is long, one pair can be installed every 30-35 meters in the middle position of the conveyor.) 4. The deviation switch should be connected to the middle frame of the conveyor through an installation bracket. The switch bracket should be welded to the conveyor frame after the conveyor is installed. The deviation switch and the deviation switch bracket should be fixed with bolts& nbsp; The classification of deviation switches includes ordinary type, wiring chamber type, and address coding type. The ordinary type refers to the two-stage deviation switch mentioned above; The wiring chamber type deviation switch is equipped with a waterproof wiring chamber on the basis of the ordinary type deviation switch. The on-site control cable can be directly connected to the wiring chamber to prevent faults caused by moisture and virtual connection of cable joints. The address encoding type deviation switch integrates XLline fieldbus technology on the basis of ordinary deviation switches, achieving address encoding function. Suitable for remote monitoring of the operation of long belt conveyors as on-site equipment, it solves the inconvenience caused by workers searching for fault points. The address encoded two-level deviation switch is connected to the comprehensive protection device (gateway) through XLline fieldbus, supporting up to 128 addresses, and multiple switches can be used simultaneously at the same address. Its main feature is that it only requires a two core cable to complete data transmission simultaneously without the need for power supply. XLline fieldbus can finally achieve flexible connection with major manufacturers' PLCs and computer interfaces. Technical indicators 1. Rated voltage: AC380V2.
