1.9.6 The control panel (HMI)
The HMI (Human Machine Interface) consists of a color TFT display, two rotary knobs with button function and
six pushbuttons.
1.9.6.1 Display
The graphic display is divided into a number of areas. In normal operation the upper part (⅔) is used to show actual
and set values and thelower part (⅓) to display status information:
Actual voltage + set value
Regulation mode CV
Actual current + set value
Regulation mode CC
Actual power +
set value
Regulation
mode CP
Various status displays (symbols, strings) and quick menu
• 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 corre-
sponding 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-clock-
wise 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 can’t be adjusted manually, like in HMI lock or remote control.
