Human-machine interface (front panel)

The front panel includes a comprehensive and flexible human-machine interface. It is divided into four sections:

1. 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.
2. 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.
3. 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.
4. On the alarm indication panel, the respective LEDs light up to indicate a possible fault or after an alarm has occurred.
