1.9.5 The control panel (HMI)
The HMI (Human Machine Interface) consists of a display with touchscreen, two rotary knobs, a button and a
USB-A port.
1.9.5.1 Touchscreen display
The graphic touchscreen display is divided into a number of areas. The complete display is touch sensitive and
canbeoperatedbyngerorstylustocontroltheequipment.
In normal operation the screen is separated into four areas of equal size, of which three are used to show actual
and set values and one to display status information:
Actual voltage display
Voltage set value input
Actual current display
Current set value input
Actual power display
Power set value inputt
Switch for P/R display mode
Actual resistance value
Resistance set value input
TouchareasMENUandLOCK
Status area
Touch areas may be enabled or disabled:
Black text or symbol = Enabled Grey text or symbol = Disabled
• Actual / set values area (blue, red, green, orange)
In normal operation the DC input values (large numbers) and set values (small numbers) for voltage, current and
power are displayed. Resistance set value of the variable internal resistance is only displayed by active resistance
mode. Once resistance mode is activated, a small touch button (“R”) appears in the green area (power). That touch
button is used to switch the area between R and P display mode.
When the DC input is switched on, the actual regulation mode, CV, CC, CP or CR is displayed in the corresponding
area,asdepictedinthegureabovewith“CC”intheredareaforcurrent.
The set values can be adjusted with the rotary knobs below the touch screen or can be entered directly via the
touchscreen. When adjusting with the knobs, pushing the knob will select the digit to adjust. Logically, the values
are increased by clockwise turning and decreased by anti-clockwise turning.
