1.9.4

The control panel (HMI)

The HMI (Human Machine Interface) consists of a display, two rotary knobs with pushbutton function and six
pushbuttons.
1.9.4.1
Display
The graphic display is divided into a number of areas. In normal operation the left upper half is used to show actual
values and the lower half is used to display status information and set values:
Set value of voltage
• Actual values area (upper half)
In normal operation the DC output values (large numbers) of voltage and current resp. of power are displayed,
depending on the selected view mode. The display format of values is according to what's listed in 1.9.4.4.
Furthermore, the actual regulation mode CV, CC or CP (see „3.2. Operating modes") is displayed here, as well as
alarms with abbreviations (OT, OVP, OCP, PF, OPP). For details refer to „3.3. Alarm conditions".
• Set values area (lower half, left and right side)
The set values of voltage and current (mode: U/I) resp. of voltage and power (mode: U/P) are displayed here and
are adjustable with the left hand and right hand rotary knobs when operating the device manually. While doing
so, the digit to adjust can be selected by pushing the corresponding rotary knob, in order to move the cursor. The
left hand rotary knob is always assigned to the DC output voltage and related parameters like OVP or U-max,
whereas the right hand rotary knobs is either assigned to the DC output current and related parameters or to the
DC output power. In remote control condition, no matter if analog or digital, the set values given from remote are
displayed here.
Logically, the values are increased by clockwise turning and decreased by anti-clockwise turning, unless they are
somehow limited by a maximum value or an adjustment limit (see „3.4.4. Adjustment limits").
