1. ‌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.
2. ‌The voltage stabilizer has no automatic adjustment function‌?

Possible reasons include sampling transformer damage, control circuit board damage, etc. The solution includes repairing or replacing damaged parts‌.
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. DC switching regulator overload‌?

If the load exceeds the voltage regulator's tolerance, the voltage regulator will burn out‌.
