1. After the wireless sensor device is installed, it appears to be beating or the number is inaccurate

Reason: There is electromagnetic interference on the site, or the signal line and the power line go to the same trunking.

Solution: The customer's selected product function does not meet the on-site operating conditions, and the transmitter with blocking function needs to be installed or replaced.

2. On the wireless sensor device, it appears that it is at fault or does not appear

Cause: The signal line is faulty in the wiring of the positive and negative levels

Solution: Disconnect the power supply, swap the orientation of the two signal lines, and press it with the terminals to power it from the beginning. In particular, PT100 RTD sensors with a three-wire output without a transmitter often present this problem when installed in the field.

3. The value displayed after the use of the wireless liquid level sensor remains unchanged

Cause: Water ingress in the trachea

Solution: Return to the factory for maintenance, drain the water in the air duct, mark the range from scratch, and then use.

4. The temperature sensor has no signal output

Reason: When the worker is in the device, because he does not understand the sensor, he uses too much force, which causes the pin of the temperature measuring element to be pulled out entirely, so that the signal loop is interrupted.

Solution: When installing, just connect the wire on the terminal, without removing the transmitter or magnetic plate, and use the terminal to press the signal lead.

5. It does not appear on the intelligent control instrument device

Reason: The meter parameters are set incorrectly

Solution: Confirm the signal type connected by the wireless sensor, and adjust the input parameters of the intelligent control instrument according to this type.
