ROS-2-FM Dust Explosion proof Anti deviation Switch ROS-2-FM Dust Explosion proof Anti deviation Switch ROS-2-FM Dust Explosion proof Anti deviation Switch Features: Simple and practical structure, stable and reliable performance, dustproof, shockproof, moisture-proof, small volume, light weight, long service life, easy installation, maintenance free. The output signal can be interlocked with on-site equipment or delivered to microcomputer control systems. The power supply has wide adaptability: 24-380V. Precautions: 1. The gear wheel of the deviation switch should be kept perpendicular to the belt. 2. It is recommended to maintain a distance of 120-160mm between the gear wheel of the deviation switch and the edge of the belt. 3. The base of the deviation switch is firmly fixed. Ordering instructions 1. Optional accessories: installation bracket. 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. Two pole deviation switch, also known as anti deviation switch. Used to detect the deviation phenomenon during the operation of belt conveyors, output alarms or shutdown signals based on the actual deviation amount of the belt, which can effectively prevent accidents caused by belt deviation. This series of deviation switches has a two-stage action function. The first level action is used for alarm, and the second level action is used for automatic shutdown. When the tape machine is running, when the tape deviates and comes into contact with the vertical roller of this switch, the vertical roller rotates. If the deviation continues to increase, the squeezing vertical roller will shift. When the deflection angle of the vertical roller exceeds 12 °, the first level switch acts and outputs an alarm signal. When the deflection angle of the vertical roller exceeds 30 °, the secondary switch acts and outputs (shutdown signal). Parameters: Voltage: 220V/380V/480V, current options: 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A. 15A
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 secondary switch signal is used for shutdown. Connect this signal to the control circuit to achieve automatic shutdown in severe deviation state< After troubleshooting, when the tape leaves the vertical roller and operates normally, the vertical roller can automatically reset. The dust explosion-proof anti deviation switch ROS-2-FM 380VAC 15A is a product in conveyor belt automation. Can be used for underground and cableway support belt conveyors; Ship loading and unloading system; Stacking/reclaiming conveyor; Tilt and shuttle conveyors; Cranes, excavators, boom limits; Skirt feeder/conveyor; 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. The dust explosion-proof anti deviation switch ROS-2-FM 380VAC 15A is suitable for belt conveyors, which can issue an alarm signal and further automatically stop the belt conveyor before serious edge wear or even tearing accidents occur due to belt deviation. The dust explosion-proof anti deviation switch ROS-2-FM 380VAC 15A can timely and effectively protect equipment safety, avoid accidents from expanding, and achieve the goal of ensuring production and protecting equipment. In addition, since signals can be sent to the control system, it is convenient to achieve factory automation control, which can also achieve the goal of reducing staff and increasing efficiency, centralized control, and facilitating production and scheduling.
