3.4.5 Manual adjustment of set values
The set values for voltage, current and power are the fundamental operating possibilities of a power supply and
hence the two rotary knobs on the front of the device are usually assigned two of the three values in manual op-
eration. Default assignment is voltage and current.
The set values can only be adjusted with the rotary knobs.
Entering a value changes it at any time, no matter if the output is switched on or o.
When adjusting the set values, upper or lower limits may come into eect. See section „3.4.4.
Adjustment limits“. Once a limit is reached, the display will show a note like “Limit: U-max” etc.
or “[i]” for 1.5 seconds.
► How to adjust values U, I or P with the rotary knobs
1. First check whether the value to be changed is assigned to one of the rotary knobs. The assignment can be
changed by switching the assignment of the right-hand rotary knob with the arrow buttons.
2. With mode UI selected and as long as the main display is active, turn the left-hand knob to adjust output
voltage and the right-hand knob to adjust the output current. In mode UP, turn the right-hand knob to adjust
the output power. The arrow buttons can be used to toggle between adjustment of current and
power set value.
3. Any set values can be adjusted with the adjustment limits. For switching the digit to adjust, push the rotary
knob that you are currently using to adjust the value. Every push moves the cursor under the digit in clock-
wise order:
3.4.6 Switching the main screen view
The main screen, also called status page, with its set values, actual values and device status can be switched from
the standard view mode with three values to a simpler mode which only shows two physical values.
The advantage of the alternative view mode is that both actual values are displayed with bigger numbers, so
they read be read from a larger distance. Refer to „3.4.3.7. Menu “HMI Setup”“ to see where to switch the view
mode in the MENU. Comparison:
Layout 1 (standard) Layout 2 (alternative)
Di󰀨erences of layout 2:
• The hidden value is shown when switching the knob assignment, which also changes the upper right half of the
display
• The actual regulation mode is displayed no matter what pair of physical values is currently shown, as the example
in the upper gure on the right side depicts with CV
