A:Self-checking function means that during the operation of a safety product, it can automatically monitor whether its key components and functions are working properly, and immediately issue an alarm or cut off the output when a fault or abnormality is found to ensure that the system is in a safe state.
A:The forced guide structure is a mechanical design used in safety components such as safety relays to ensure that the normally open and normally closed contacts will not close at the same time when a relay contact failure occurs (such as contact adhesion). It can effectively improve the system's fault detection capabilities and is an important guarantee for building a reliable industrial safety control system.
A:When the error indicator light of the safety light curtain lights up, you can quickly troubleshoot and solve it by following the steps below:1. Confirm the fault code by checking the manual: Check the corresponding meaning of the error light according to the manual to clarify the fault type.2. Check the optical axis status: Make sure there is no obstruction (such as foreign matter, dust, oil) between the transmitter and the receiver. Clean the window and realign the optical axis if necessary.3. Confirm the wiring and power supply: Check whether the wiring is correct and firm, whether the power supply is stable, and eliminate problems such as looseness and broken wires.4. Check interference factors: Check whether there is crosstalk, strong light interference or electrical interference between the light curtains, which can be improved by dislocation installation, optimized grounding, etc.5. Reset or restart the system: After troubleshooting, some light curtains need to be powered off and restarted or reset by the controller to return to normal.6. Check external control devices: If a safety relay or controller is connected, its status and logical configuration must also be checked.If the above methods are ineffective, it is recommended to contact the original manufacturer or supplier technical support for further investigation.
A：To prevent the safety carpet from misoperating due to debris under the carpet, the following measures can be taken:Keep it clean: Clean the area under the carpet regularly to prevent dust, metal shavings, screws and other foreign objects from accumulating.Use protective pads or frames: Install protective plates or support structures under the safety carpet to prevent small objects from directly contacting the trigger surface.Adjust sensitivity (if applicable): Some safety carpets support sensitivity adjustment function, which can be adjusted to reduce false triggering according to the actual environment.Regular inspection and maintenance: Incorporate carpet detection into the daily inspection process, and handle false alarms in a timely manner to ensure stable operation of the equipment.Install reminder signs: Remind personnel not to leave items in the carpet area and enhance on-site standardized management.These methods can effectively reduce misoperations caused by debris and improve the reliability of the use of safety carpets.
A：The following steps should be followed to handle faults and maintenance of security door locks:1. Regular inspection: Regularly check the lock body, connecting wires and installation parts to ensure that there is no looseness, wear or corrosion.2. Troubleshooting: When an abnormality occurs, check whether the power supply, cable connection, and security control system signal are normal.3. Replace damaged parts: If mechanical wear or electrical damage is found, the corresponding parts should be replaced immediately.4. Cleaning and maintenance: Keep the door lock surface and latch area clean to avoid dust and foreign matter affecting normal operation.5. Functional test: Perform functional test after maintenance to confirm that unlocking, locking and signal interaction with the control system are normal.6. Follow the manufacturer's guidelines: Follow the maintenance instructions provided by the manufacturer to avoid unauthorized disassembly that affects safety performance.Regular maintenance and correct fault handling are the key to ensuring long-term and reliable operation of security door locks.
A：The maintenance procedures of ultrasonic sensors mainly include the following points:Regularly clean the sensor surfaceUse a clean and soft cloth to wipe the sensor probe to avoid dust, oil or water droplets affecting ultrasonic transmission and reception.Check the installation firmnessMake sure the sensor is not loose or offset to avoid detection errors caused by vibration or impact.Verify the detection performancePerform tests regularly to verify its detection distance, response time and stability to ensure that it is in the best working condition.Check the cables and connectorsCheck for wear, looseness or corrosion to ensure normal power supply and signal transmission.Avoid water accumulation or condensationIn high humidity or open air environments, the protective cover or drainage device should be checked to prevent affecting the performance of the sensor.Software or parameter checkIf using an intelligent ultrasonic sensor, the set parameters should be checked regularly to see if they are incorrect or need to be updated.The above maintenance measures can effectively extend the service life of the ultrasonic sensor and ensure its detection accuracy and system stability.
