Fault analysis of Bernard electric valves
Thread Content
Does any of you have experience working with Bernard electric valves? I have a Bernard electric valve whose fuse has burned out for no apparent reason. The current reading is only 500 mA, so it doesn’t seem to be a fuse related to the power circuit. Since there’s no replacement available, I used one of the thin copper wires from a 0.75mm2 multi-strand wire as a temporary substitute. Now it’s difficult to control the valve, both locally and remotely; a triangle with an exclamation mark flashing appears in the lower left corner of the LCD screen. Given that the fuse has burned out, I think it might be due to overcurrent or torque protection issues. However, the valve doesn’t seem stuck when operated manually. I’m not sure how to diagnose the fault in this electric valve
It’s too professional; it requires a specialist to answer
Check if there are any fault code messages on the LCD display of the Bernard electric valve Check the manual to find out exactly what the fault is. Also, examine whether the contacts of the local/remote control switch are functioning properly; if the switch is working fine, there may be a problem with the circuit board.
It’s such that when the exclamation mark appears, it’s impossible to perform any operations remotely, even from the same location. The fault has disappeared for now; I’ve checked and there are no previous faults recorded
