Last updated 2 years ago

Environment and Parameter Check

  1. Confirm that the device power supply is normal.

  2. Confirm whether the confirmation page data is consistent with the communication data.

  3. Confirm that the OCT function is enabled and defined correctly (parameter ). If E02 uses pulse v2, please confirm the OCT Pulse troubleshooting process.

  4. Confirm that the OCT preset state is on "NC" or off "NO" (parameter ).

  5. Confirm that the relevant parameter settings of Alarm A, B, and C meet the requirements.

  6. Confirm that the circuit wiring is correct, the external power supply connection and power supply are normal, the unused wiring is insulated, and there is no magnetic field interference in the surrounding area.

Hardware, Wiring, and Program of the Receiver Check

  2. Use the current gear of the three-purpose ammeter to connect between OCT+ and the positive pole of the power supply, and confirm whether there is current flowing when C0=1. Or use the voltage range to confirm whether there is a voltage difference close to the power supply voltage between OCT+ and OCT- when S0=1. If it is found that there is no correct output for the first time, please reconfirm the power supply circuit.

Results and Actions

  1. The OCT output is normal, and the receiving end equipment and program are also normal. If the data is still abnormal, confirm other causes of the abnormality (pipe size, flow rate).

  2. The main unit of this device unit may be damaged. If you have other units at hand, you can conduct a cross test to confirm that the receiving device, data processing program or line are all normal.

  3. Record the serial number of the fuselage, the wiring diagram (all flowmeter-related wiring) and the model brand of the receiving end, and contact the original factory.

  4. Please confirm whether there is any abnormality in the receiving device, data processing program or line.

Users need to refer to the actual situation, detailed troubleshooting, please contact LORRIC.

Enter the parameter to test the receiver. In the setting screen, if you set it open, it will not conduct, but if you set conduct, it will conduct.
