During daily operations, several issues can arise during pull testing. Below are some common problems along with their troubleshooting methods. I hope this guide helps everyone avoid or resolve these issues effectively:
1. After the computer software is online, a message box appears indicating an overload.
Troubleshooting Steps:
First, check if the communication cable between the computer and the test machine is properly connected. Ensure that the correct sensor has been selected in the software. Also, verify if the sensor was damaged during the last test or keyboard operation. Check whether the calibration function was used before the issue occurred, and confirm if any manual changes were made to calibration values, parameters, or hardware settings. These steps can help identify and fix the problem.
2. The power supply of the pull test machine is not working, and the device cannot move up or down.
Troubleshooting Steps:
Start by checking if the power cable is securely connected to the test machine. Make sure the emergency stop button is not engaged. Verify that the voltage supplied to the machine is within the normal range. Additionally, check if the fuse on the power socket is blown. If so, replace it with a spare one. These checks often resolve the issue.
3. The test machine has power but still cannot move up or down.
Troubleshooting Steps:
It’s possible that the machine is undergoing a self-test after startup, which usually takes about 15 seconds. Wait for a moment to see if movement resumes. Next, ensure that the upper and lower limit switches are correctly positioned and that there is enough space for the device to move. Finally, double-check the power supply voltage to make sure it is stable and meets the required specifications.
By following these steps, most common issues can be resolved quickly and efficiently. Always remember to refer to the user manual for more detailed instructions, and don’t hesitate to contact technical support if the problem persists.
