Step 1 Check whether each connector on the UI board is short-circuited
1. Disconnect the power supply of the device.
2. Set a multimeter to the on-off mode.
3. Connect one end of the multimeter to the GND position, and connect the other end to the 24V, 5V, and 3.3V connectors respectively.
4. Fill the result in the chart.
Connector | Whether it is short-circuited or not |
24V connector | |
5V connector | |
3.3V connector |
Step 2 Measure the actual voltage of each connector
1. Unplug the ports on J10.
2. Turn on the power switch of the device.
3. Use a multimeter to measure the actual voltage value of 24V, 5V, and 3.3V connectors.
4. Fill the result in the chart.
Connector | Actual voltage value |
24V connector | |
5V connector | |
3.3V connector |
Step 3 Measure the actual voltage of all ports on J10
1. Unplug the ports on J10.
2. Use a multimeter to measure the actual voltage value of all ports on J10.
3. Fill the result in the chart. ("/" means no measurement)
Port 10: / | Port 8: | Port 6: / | Port 4: | Port 2: |
Port 9: / | Port 7: | Port 5: | Port 3: | Port 1: |
The following chart is the normal voltage for reference.
Port 10: / | Port 8: GND | Port 6: / | Port 4: GND | Port 2: 24V |
Port 9: / | Port 7: GND | Port 5: 3.3V | Port 3: GND | Port 1: 24V |
4. Send the results to the after-sales service.
