Human-machine interface (front panel)
![](/public/img/sub/business/ups01_03_3.jpg)
The front panel includes a comprehensive and flexible human-machine interface. It is divided into four sections:
- The system panel shows the system’s current state of operation (i.e., which part of the system is currently supplying the load and which is in stand-by mode). LEDs also indicate possible faults.
- Use the operations panel to turn the system on and off. The lamp-test button indicates whether all LED indication lights are functioning properly. To shut down the system, you have to press the ON and OFF buttons at the same time.
- The display unit consists of a liquid crystal display, an alarm LED, an acoustic alarm, and a keypad. From here, the user can set operational parameters, obtain current measurement data, and access the event and alarm logs.
- On the alarm indication panel, the respective LEDs light up to indicate a possible fault or after an alarm has occurred.
