The control panel (HMI)
The HMI (Human-Machine Interface) consists of a display with touchscreen, two rotary knobs, a button and an
USB port.
1.9.6.1
Touchscreen display
The graphic touchscreen display is divided into a number of areas. The complete display is touch sensitive and
can be operated by finger or stylus to control the equipment.
In normal operation the left hand side is used to show actual and set values and the right hand side to display
status information:
Actual voltage display
Voltage set value input
Actual current display
Current set value input
Actual power display
Power set value input
Actual resistance value
Resistance set value input
Touch areas may be enabled or disabled:
This applies to all touch areas on the main screen and all menu pages..
• Actual / set values area (left hand side)
In normal operation the DC input values (large numbers) and set values (small numbers) for voltage, current and
power are displayed. The resistance set value of the is only displayed when resistance mode is activated.
While the DC input is switched on, the actual regulation mode CV, CC, CP or CR is displayed next to the corre-
sponding actual value, as in the example figure above.
The set values can be adjusted with the rotary knobs next to the display screen or can be entered directly via the
touchscreen. When adjusting with the knobs, pushing the knob will select the digit to be changed. Logically, the
values are increased by clockwise turning and decreased by anti-clockwise turning.
