1.9.5 The control panel (HMI)
The HMI (Human Machine Interface) consists of a display, two rotary knobs and six pushbuttons.

Various status displays (symbols, strings)
• Actual / set values area (blue / green / red)
In normal operation the DC output values (large numbers) and set values (small numbers) for voltage, current
and power.
While the DC output is switched on, the actual regulation mode CV, CC or CP is displayed above to the correspond-
ingsetvalue,asshowninthegureabovewithexample“CV”.
The set values can be adjusted by rotating the knobs below the display, whereas pushing the knobs are used to
select the digit to be changed. Logically, the values are increased by clockwise turning and decreased by anti-
clockwise turning. The current assignment of set a value to a knob is indicated by the corresponding set value
being displayed in inverted form and also by the knob depiction in the status area showing the physical sign (U,
I,P). In case these are not shown, the values cannot be adjusted manually, like in HMI lock or remote control.
