1.9.6 The control panel (HMI)
The HMI (Human Machine Interface) consists of a display with touchscreen, two rotary knobs, a pushbutton and a 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 oper-
ated by nger or stylus to control the equipment.
In normal operation the left hand side is used to show actual values and set values and the right hand side is used to display
status information:
Actual voltage display
Voltage set value input
Additional status
Status area
Actual current display
Current set value input
Touch area for
rotary knob assignment
DC input status
Actual power display
Power set value input
Actual resistance display
Resistance set value input
Touch areas for menu
access
Quick menu
Touch areas may be enabled or disabled:
Black text = Enabled
Grey text = Touch area temporarily
disabled
This applies to all touch areas. Some can additionally show a small padlock sign, indicating that the fea-
ture is permanently locked, usually due to a specic setting.
• Actual / set values area (left hand side)
In normal operation the actual values (large numbers) and set values (small numbers) for voltage, current, power and re-
sistance on the DC input are displayed. The actual and set of resistance are only displayed while resistance mode is active.
When the DC input is switched on the actual regulation mode is displayed as CV, CC, CP or CR, next to the corresponding
actual value, as shown in the gure above exemplary with CC.
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.
