• First: plating rectifier power indicator light does not on

Solution: Make sure the power is connected, the switch blade is closed, and the three-phase is properly, if not, Connect the power supply, closed switch blade.

  • Second: the power indicator is good, but working light not on

Solution: check the Start switch, if it is in the start position, if yes, but the machine not work, then put again the start switch on the start position. And see.

  • Third: working indicator light is on, but the current and voltage does not move

Solution: Check the current limiting constant and steady flow pressure limiting knob is adjusted to the lowest position, the limiting regulator, steady flow pressure limiting plating process according to claim rotary knob to the appropriate position.

  • Fourth: during working, it suddenly has no current output, but working indicator light is good

Solution: Check the connection from the power output to the plating bath line is disconnected, replace or reconnect the cable.

  • Fifth: during working, the rectifier is suddenly has no current output, protection indicator light flashes

Solution:

Case 1: check the environment temperature is too high, if the fan is working properly. Exclude fan failure, improved ventilation;

Case 2: determine whether the instantaneous overcurrent protection, according to the boot process to reboot, power supply is working.

Case 3: the input voltage is normal, whether the overvoltage, undervoltage, whether the three-phase input phase; after the exclusion of distribution line power failure, according to the boot process to reboot.

Case 4: check the power rectifier short circuit, replace the rectifier.
