During daily operations, there are several common issues that may occur during pull testing. Below are some typical problems along with their troubleshooting methods. I hope this guide helps everyone resolve these issues more efficiently:
1. After the computer software is online, an error message appears indicating that the message box is overloaded.
Troubleshooting Steps:
- First, check if the communication cable between the computer and the test machine is properly connected.
- Ensure that the correct sensor is selected in the online settings.
- Verify if the sensor was accidentally hit or damaged during the last test or keyboard input.
- Check if the software calibration or adjustment function was used prior to the issue occurring.
- Confirm whether any manual changes were made to calibration values, sensor parameters, or hardware settings.
2. The power supply of the pull test machine is not working, and the device cannot move up or down.
Troubleshooting Steps:
- Inspect the power cable connection to the test machine to ensure it is securely plugged in.
- Make sure the emergency stop switch is not engaged (it should be in the "released" position).
- Check the voltage supplied to the test machine to confirm it is within the required range.
- Examine the fuse on the power socket; if it's blown, replace it with a spare one.
3. The test machine has power, but it still cannot move up or down.
Troubleshooting Steps:
- Allow the system to complete its self-test after booting, which usually takes around 15 seconds.
- Ensure that the upper and lower limit switches are in the correct position and that there is enough space for movement.
- Double-check the power supply voltage to make sure it is stable and meets the machine’s requirements.
By following these steps, most of the common issues can be resolved quickly. It's always a good idea to maintain a regular inspection schedule and keep detailed logs of any changes or errors encountered. This will help prevent future problems and improve overall efficiency.
