icCommon faults of card meter

1 The device does not display

The digital tube displays nothing, or the user information to be queried

1．1 reason   

1．1．1 The fuse is blown.   

1．1．2 The power transformer on the control board is faulty.   

1．1．3 ICThe jam is too dirty or inserted in reverse.WillICWipe the card clean before inserting the card.If the problem has not been solved by the above method, the back cover of the integrated circuit controller needs to be opened, inserted into the management card, press the clear button to clear it, and re-correct it.ICEnter relevant information on the card.

2 The device shows electrical energy.But the output is powered

2．1reason   

2．1．1The deviceDZone48The coil burned.   

2．1．2The terminal strip wiring is loose.   

2．2Troubleshooting   

2．2．1Check the deviceDZ—48Whether the coil is burned or not, it will be repaired or replaced.   

2．2．2Use a screwdriver to tighten the terminal screws to make them well-wired.

3 The device shows that the electrical energy is zero.But don't jump

3．1reason   

3．1．1The deviceDZone48The coil burns or the neutral wire is broken, causing it to not trip when it should be tripped.   

3．1．2The terminal strip leads are loose.   

3．2Troubleshooting   

3．2．1Check the deviceDZ—48Whether the coil is burned or whether the neutral wire is broken, if the neutral wire is burned or the neutral wire is broken, replace or connect it.   

3．2．2Tighten the terminal screws to ensure good wiring.

4 The number of power attacks does not match the number displayed by the computer

4．1reason   

4．1．1Electricity meter andICThe constants of the card are inconsistent.   

4．1．2The sensor head and dial position of the photosensitive sensor are inappropriate.   

4．1．3The aluminum disk of the power meter is dirty, causing misreading sensors.   

4．2Troubleshooting   

4．2．1FixedICcard constant so that it is consistent with the power meter constant.

4．2．2Open the meter cover and adjust the position of the photosensitive sensor's sensor head and dial to keep the rotation number of the electricity meter consistent with the photosensitive pulse.

4．2．3Wipe or clean the dial dust points so that the sensor can conduct normal readings.
