PWR-01 series shut off the output, showing “AL/AC” on the panel with the red ALM LED on. What should I do?

カテゴリ-
INDEX

“AL/AC” indicates that the AC-FAIL (low AC input protection function) is activated.
This situation may be caused by a short interruption.
When the following CONFIG settings are set to the factory default, the AC-FAIL will persist even after the AC input voltage recovers.
To release the AC-FAIL at the AC input voltage recovery, set CF20 (status when recovering from AC-FAIL protection) of the CONFIG setting to Auto.
To turn on the output at power-on, set CF45 (output state at power-on) to ForC (Force).
