Adjustment limits
Adjustment limits are only effective on the related set values, no matter if using manual adjust
-
ment or remote control setting!
Defaults are that all set values (U, I, P, R) are adjustable
from 0 to 102%.
The full range may be obstructive in some cases, espe
-
cially for protection of applications against overvoltage.
Therefore upper and lower limits for current (I) and voltage
(U) can be set separately, which then limit the range of
the adjustable set values.
For power (P) and resistance (R) only upper value limits
can be set.
► How to configure the adjustment limits
1.
While the DC terminal is switched off, tap
on the main screen.
2.
Tap on group “
Limits
”
on the left side to open the list of limits. They are grouped and colored for distinction.
Values are adjusted by tapping on them, in a window popping up with a numeric pad. Values further down
in the list are accessed by swiping the list up.
3.
Adjust the desired value and submit with
.
The adjustment limits are coupled to the set values. It means, that the upper limit may not be set
lower than the corresponding set value. Example: If you wish to set the limit for the power set
value (P-max) to 6000 W while the currently adjusted power set value is 8000 W, then the set
value first would have to be reduced to 6000 W or less, in order to set P-max down to 6000 W.

Changing the operating mode
In general, the manual operation of the device distinguishes between three operating modes: U/I, U/P and U/R.
They are tied to set value input using the rotary knobs or the on-screen numeric pad. The current assignment can
be switched anytime if you want to adjust a set value which is currently not assigned to any of the knobs.
► How to change the operating mode (two options)
1.
Unless the device is in remote control or the panel is locked, tap on the
depiction of the right-hand knob on the screen (see figure to the right) to
change its assignment between I, P and R (if resistance mode is activated)
for source mode (PS) and after that to I, P and R for sink mode (EL). The
knob will display accordingly, with letters.
2.
Directly tap on the colored areas with the set values, like shown in the figure
to the right. The set value field, when inverted, indicates the assignment
to the knob. In the example in the figure it has U and I (sink) assigned,
which means U/I mode.
Depending on the selection the right rotary knob will be assigned different setting
values, the left knob is always assigned to the voltage.
In order to change the other values, like P or R while U/I is
active, and without switching the assignment all the time, direct
input can be used. See section 3.5.6.
The actual operating mode, which is only indicated while the DC terminal is switched on, solely depends only on
the set values. For more information see section
“3.3. Operating modes”.
