ROS-2FM Dustproof and Explosion proof Anti Deviation Switch ROS-2FM Dustproof and Explosion proof Anti Deviation Switch ROS-2FM Dustproof and Explosion proof Anti Deviation Switch ROS-2FM 380VAC 15A Installation and Adjustment 1. The deviation switch is set on both sides of the conveyor belt, and the vertical roller should be perpendicular to the edge plane of the conveyor belt, and the two sides of the conveyor belt should be located at 1/3 of the height of the vertical roller& 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 set every 30-35 meters in the middle of the conveyor); 4. The deviation switch is 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 installation is completed. The deviation switch and the deviation switch bracket are fixed with bolts. The two-stage deviation switch consists of a hard contact and an address encoding circuit. Two micro switches are used for the first level deviation alarm hard contact and the second level deviation alarm hard contact, respectively, for the conveyor deviation alarm and emergency stop. When the address encoding two-stage deviation switch acts, the address encoding circuit will immediately send alarm information and address encoding through the communication circuit. The address coding two-level deviation switch uses a micro switch as a hard contact inside, which is safe and reliable. In the event that the address coding switch loses power, the two-level deviation switch can have the function of a normal protection switch without affecting the safety protection function& nbsp; The basic principle of dustproof and explosion-proof anti deviation switch ROS-2FM 380VAC 15A is that when the conveyor belt deviates and comes into contact with the switch vertical roller during operation, the vertical roller rotates automatically. If the deviation continues to increase, the squeezing vertical roller will shift. The first level switch signal is used for alarm. If this signal is connected to the running adjustment device, it can achieve automatic adjustment of running deviation without stopping the machine. The second level switch signal is used for shutdown. Connect this signal to the control circuit to achieve automatic shutdown under severe deviation. After troubleshooting, when the tape leaves the vertical roller for normal operation, the vertical roller can automatically reset.
