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 output 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, you can
switch the operation anytime. Tap on the depiction of the right-hand knob
(see figure to the right) to change its assignment between I, P and R (if
resistance mode had been enabled), which is then displayed accordingly.
2.
Directly tap on the colored areas with the set values, like shown in the
figure to the right. The physical unit next to the set value, when inverted,
indicates the assignment to the knob.
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 3.4.6. for details.
The actual operating mode, which is only indicated while the DC output is switched on, solely depends on the set
