AL.003 Under Voltage |
The voltage of the main circuit is lower than the standard voltage | ⊗ | NO | Auto cleared after the voltage returns to normal. |
| Causes | Checking Method | Actions |
|---|---|---|
| The input voltage of the main circuit is lower than the rated allowable voltage | Check if the input voltage wiring of the main circuit is normal | Re-confirm the voltage wiring |
| No power supply for the main circuit | Use the voltmeter to see if the voltage of the main circuit is normal | Check the power switch |
|
Wrong power input (incorrect power system) |
Use the voltmeter to see if the power system matches the specification | Apply to the correct power supply or serial adaptor |

| Other reasons | Checking Method | Actions |
|---|---|---|
| Capacitor charging circuit is abnormal (TN) | If the power is turned off for a long time and then power-on, there is no “switching” sound of the internal relay. It may be that the soft start circuit is faulty and the capacitor charging is too slow and easy to occur. AL.003! | Contact for repair |
