-
1. The voltage stabilizer cannot start?
Possible reasons include the wrong phase sequence of the input power line, the air switch in the machine is not turned on or damaged. The solution is to swap any two power connections or check whether the power line is normal, close the switch or replace the switch.
-
2. The voltage stabilizer cannot start the manual control mode without voltage adjustment function?
Possible reasons include limit switch failure, boost and down pressure button failure, poor contact of the voltage stabilizer motor power supply, etc. The solution includes replacing the limit switch, checking the connection line, replacing the button, connecting the voltage stabilizer power line, etc.
-
3. No output voltage from the voltage regulator?
Possible reasons include open circuit of normally closed contact of stop button, broken contact of voltage regulator button, etc. The solution is to replace damaged parts.
-
4. Decrease in voltage regulator load capacity?
Possible reasons include defective brushes, poor contact between brushes and voltage regulator coil, etc. The solution includes replacing brushes, adjusting brush spring pressure and brush position, etc.
