1.9.5 The control panel (HMI)
The HMI (Human Machine Interface) consists of a display with touchscreen, a rotary knob, a button and a USB-A port.
1.9.5.1 Touchscreen display
The graphic touchscreen display is divided into four areas. The complete display is touch sensitive and can be
operated by nger or stylus to control the equipment. Only exception: switching the DC input on or off can only be
done using the pushbutton right next to the display.
In the main screen, like depicted below, the three coloured areas are used to show actual values and to enter set
values while if manual control mode is active:
Actual voltage display
Voltage set value input
Actual current display
Current set value input
Actual power display
Power set value input
Touch area MENU
and HMI lock
Status area
Touch areas may be enabled or disabled:
Black text = Enabled Grey text = Disabled
• Actual / set values areas (blue, red, green)
In normal operation the DC input values (large numbers) and set values (small numbers) for voltage, current and
power are displayed.
While the DC input is switched on, the actual regulation mode CV, CC or CP is displayed below the corresponding
actual value’s physical unit, as show in the gure above with CC. More about regulation modes in „3.2. Regulation
modes“.
The currently selected set value can be adjusted with the rotary knob next to the display screen or can be entered
directly via the touchscreen. During manual control, the set value selection is done by tapping the coloured areas.
Alternatively to value adjustment with the knob, values can be entered directly with a ten-key pad by tapping on
the small ten key pad icon ( ).
Pushing the knob will select the digit to be changed. Logically, the values are increased by clockwise turning and
decreased by anti-clockwise turning.
