I have a question: for an E+H Promag 50, 8-inch stainless steel sewage pipe, the error code is #321, and the actual current reading is 3.75A. My question is, do friends think it’s usually a problem with the electrodes or the circuit board? ? How to determine where the fault lies? If it’s just a problem with the board, can a Promag 53 head or board be used as a replacement? Thank you very much.
Check its operation manual; the image is a screenshot of that manual
The coil current is out of range; measure the coil resistance – it should be around 100 ohms generally, neither too high nor too low. If the coil resistance is fine, then check whether the plug is loose; if that doesn’t work, try using a different amplifier board
After swapping the board with one from another table, the one from the other table still works fine, while this one continues to have the same issue. There is already a PROMAG 53; can it be used to replace the Promag 50 directly? ? ?
Is this a problem with the sensor? I was wondering if the problem with your watch has been resolved? I now also have a watch with the same problem
