1. First, check whether the disconnection detection is set in the computer parameters.
2. The disconnection detection is set in the computer parameters, but it still does not detect after all the machine heads are disconnected:
Check the indicator on the motherboard, check D29 for 91 model, D16 for D3095 model, L35, L36 for D1807 model. Check XJIA, DXQD for 08 model. For 18/28 models, check XIJA, DXQD. When the machine is running normally, the indicators D29, D16, L35, XIJA should flash, D30, D18, L36 should always be on, and the DXQD indicator should flash. When the above indicator status is wrong, there is a problem with the motherboard and needs to be replaced.
3. When the above indicator status is correct, check CZ018 for 91/95 models. Check A8 for 07 models and CZ0812 for 08 models. Check CZ5812 sockets for 18/28 models, and go to the disconnection detection board on the last head of the machine. Socket, the three-position disconnection detection board is CZ1, and the two-position disconnection detection board is CZ011. Whether the corresponding connection is connected or not, if it does not work, it proves that the signal is not transmitted to the disconnection detection board and needs to be repaired to make it connected.
4. One of the heads is not detected, and the other heads are normal:
The disconnection detection board on this head has a problem and needs to be replaced.
The three-position disconnection detection board checks the CZ1 signal socket, and the two-position disconnection detection board checks whether the CZ011 signal socket is plugged in.
5. False alarm (after the machine runs a few times, all the indicator lights on the disconnection detection board are on)
The broken wire decoding board is damaged. Several broken wire decoding board models are: DXYMB, EF104, EF119.
6. After a machine head is disconnected, the indicator lights of all disconnection detection boards are on:
Check whether the 12V voltage is normal (12V lower than 10V will cause this phenomenon, and the power supply needs to be replaced)
Damage to the disconnection detection board on a certain machine head can cause this phenomenon.The processing method can be to remove the signal lines on the disconnection detection board one by one until the damaged board is found and replaced.
According to the method of 3, check whether there is a short circuit between the signal lines.
7. After one head is broken and the embroidery is repaired, the indicator lights of the other head broken detection boards are all on:
Check D36 for 91 model, D21 for 95 model, L37 for 07 model, and FSW indicator for 08/18/28 model. When the machine is in the mending state, these indicators should be on. If they are not on, it means that there is a problem with the main board. Need to be replaced.
According to the method 3, check the signal line for poor contact and disconnection.
8. False alarm with bottom thread detection function. If a certain needle position of a certain head cannot be driven, and always alarms, first check whether the small wheel of the needle position rotates normally. If it is correct, pull down the connection cable between the bottom thread detection board of the head and the broken detection board to see if the false detection phenomenon still exists, if not, replace the bottom thread detection board.
