Environment and Parameter Check

  1. Confirm if the power supply works fine.

  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.

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

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

Hardware, Wiring, and Program of the Receiver Check

  3. Please confirm that the value and unit of E14 (Pulse unit) are the same as those required by the receiver program. For details, please refer to the description of the parameter table.

  5. 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 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 parameter , you can set the number of pulse output per second, please confirm at the receiving end whether you have received the corresponding data, especially whether the number is normal.

Please confirm that the parameter (Pulse width) is greater than or equal to the minimum pulse duration requirement of the receiving device.

Enter the parameter to test the receiving end. In the setting screen, if you set open, it will not conduct, and if you set conduct, it will conduct.
