Common Faults and Solutions for Ultrasonic Level Transmitters

Ultrasonic level transmitter common faults and their troubleshooting methods are as follows:

　　1. Keyboard keys ineffective: Check whether the keyboard connection is normal.

　　2. No display on the panel but the transducer emits sound: Check whether the LCD screen connection is normal.

　　3. Screen error message ERR02: The ID of the transducer and transmitter are inconsistent. Set the IDs to match via the buttons.

　　4. Screen error message ERR01: Check whether the transducer connection is normal.

　　5. The instrument displays normally, but the output signal current is abnormal: Check whether the wiring is correct, whether the current load impedance meets the requirements, and whether the central control room module is configured properly.

　　6. No display on the screen and no sound from the transducer: Check whether the power supply is normal.

　　7. Relay operates abnormally: Check whether the relay settings meet the requirements.

　　8. The instrument and the host computer cannot communicate: Check whether the wiring, ID, communication rate, and communication protocol are correct.
