Description
WRR-130 WRR-121 WRR-122 WRR-123 WRR-120 B thermocouples
Product introduction:
WRR-130 WRR-121 WRR-122 WRR-123 WRR-120 B thermocouples, after the wireless sensor is installed, the display may be displayed in batches or inaccurately. Solution: The performance of the product selected by the customer does not meet the site conditions, and the transmitter with isolation function needs to be installed or replaced.
1. After the wireless sensor is installed, the display may jump or display inaccurate numbers.
Cause: There is electromagnetic interference at the scene, or the same cable trough where the signal line and the power line run.
Solution: The performance of the product selected by the customer does not meet the site conditions, and the transmitter with isolation function needs to be installed or replaced.
2. When the wireless sensor is installed, it is displayed incorrectly or not.
Cause: The wiring of the signal line is positive or negative
Solution: Disconnect the power supply, swap the positions of the two signal wires, press the terminals tightly, and power on again. In particular, the pt100 thermal resistance sensor with a three-wire output without a transmitter often has this problem when it is installed on site.
3, the value displayed by the wireless liquid level sensor does not change
Reason: Water in the air duct
Solution: return to the factory for maintenance, drain the water in the air pipe, recalibrate the range, and then use it.
4 、 No signal output from temperature sensor
Cause: When the worker did not know the sensor during installation, he used too much force, which caused the whole pin of the temperature measuring element to be pulled out, and the signal circuit was interrupted.
Solution: When installing, you only need to connect the wires to the terminals without removing the transmitter or magnetic board, and you can press the signal leads with the terminals.
5. Not displayed on the installation of intelligent control instruments
Cause: Instrument parameter setting is incorrect
Solution: First confirm the signal type of the wireless sensor, and adjust the input parameters of the intelligent control instrument according to this type.
