Product Application & Details:
Trouble shootings guid:
| Fault | Possible reason | Suggested solution |
| Output is 0mA | Electrical connection problem | 1. Check the power supply and the voltage should be from within the range of 14V to 32V. 2. Check the cable connection of 4-20mA terminal. 3. Check the 4-20mA configuration of the controller. |
| Optical window pollution | Clean the window with the accessory paper | |
| Visibility along the path of the beam is very low due to fog, blizzard, or sandstorm
| 1) Ensure that the receiver is visible from the sender. If you can see, even if there is some difficulty, poor visibility is not a problem; 2) If you cannot see the receiver from the sender, wait until visibility improves. | |
| Output is 1.5mA | Beam block | Inspect the optical path between the sender and receiver and remove any obstacles that may exist. |
| The sender and receiver are not aligned
| 1) Connect the computer or operator to the receiver and check the signal; 2) If the signal is low, use the auxiliary alignment device to align until the signal reaches the required level. | |
| Current leakage | Not earthed | Check the reliability of the terminal grounding of the device. |
| Cannot communicate with computer RS485
| Communications problem | 1) Check the power supply voltage of the device; 2) Check the address of the connection line of the serial port; 3) Replace the serial connection line; 4) Restart the data debugging assistant on the computer. |
| Visual laser light source gives off weak light | Battery is low | Replace the battery |
| Connector ports are not clean and contaminated | Scrub gently with an alcohol sponge | |
| Large deviation of current output | Incorrect current calibration | Re-calibrate the output current |
