Troubleshooting and error codes
| Trouble | Check point | Cause |
|---|---|---|
| The unit cannot be turned on. | None of the LEDs light up within 5 minutes after the power turned ON. | - The power cord is not connected or is broken. - The power switch is defective. - The fuse is burnt. |
| Excessive output | Neither the output voltage nor the output current decreases. | - The power transistor is broken or the control circuit is malfunctioning. |
| Unstable output | 1) Is there any change in the power voltage? 2) Can any oscillation be observed? 3) Is any strong magnetic or electric field present near the unit? |
1) The power voltage exceeds the limits of a rated input voltage. 2) Oscillation can be caused by special types of loads. 3) The unit should be separated from the oscillating source. |
