What Abnormal Operation Tests Should Be Carried Out Before The Photoelectric Guide Device Is Officially Used?

The photoelectric guide device can correct the deviation of coils such as web film, non-woven fabric and woven fabric. It can correct the deviation of various coil materials such as web film, metal foil, non-woven fabric and woven fabric. The controller can select the heel and follow-up methods according to the different materials, and freely select single/double electric eye detection to meet the needs of various materials.

Before the photoelectric guide is officially used, we must conduct an abnormal operation test. The purpose of the test is to improve the reliability of the system and avoid undue accidents as much as possible. The abnormal operation test can be carried out as follows:

1. External sudden power failure experiment. When the device is operated manually or automatically, no matter under any circumstances, the sudden power-off of the external can be reliably stopped, and the device can be restored to normal operation by the specified operation steps.

2. emergency breaking test. When the device is running manually or automatically, no matter what the circumstances, for the emergency breaking operation (such as pressing the emergency stop button on the control panel), the photoelectric guide device can be reliably stopped, and the specified operation steps can be Resume normal work.

3. detection switch failure test. Consideration should be given to the possibility of system detection switch failure, especially for components that are prone to collision, interference, and safety of mechanical components, and abnormal tests should be performed on signals such as end-of-stroke detection. It must be ensured that even if a certain detection switch is defective or damaged, it still does not. A safety incident will occur.

4. Execution component failure test. The possibility of defective components of the photoelectric web guide system device system should be considered, especially for the execution parts that are prone to mechanical collision, interference, and safety. The abnormal test should be carried out, and it must be ensured that even if an actuator is defective or damaged, it will not A safety incident has occurred.
