PSI 9000 DT Series
3.4.4 Adjustment limits (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, especially for pro-
tection 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.
On the main screen, tap to access the SETTINGS menu.
2.
Tap the arrows to select “ 3. Limits”.
3.
In each case a pair of upper and lower limits for U/I or the upper limit for P/R are assigned to the rotary
knobs and can be adjusted. Tap the selection area for another choice
.
4.
Accept the settings with .
The set values can be entered directly using the ten-key pad. See “Direct input” touch area
(bottom centre)
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 1000 W while the currently adjusted power set value is 1100 W, then the
set value first would have to be reduced to 1000 W or less.
3.4.5 Changing the operating mode
In general, the manual operation of a PSI 9000 DT distinguishes between two operating modes which are tied to
set value input using the rotary knobs or ten-key pad. This assignment has to be switched manually if you want to
adjust any of the three set values which is currently not selected.
► How to change the operating mode (two options)
1.
Unless the device is in remote control or the panel is locked, you switch the operation
anytime. There are two options: either tap the depiction of the right-hand knob (see
figure to the right) to change its assignment between I, P and R, which is displayed
on the knob depiction, or
2.
you directly tap on the coloured areas with the set values, like shown in the figure
to the right. The unit next to the set values, when inverted, indicates the assign-
ment of the knob. In the example in the figure it has U and P assigned, which
means U/P 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 avoid constant changing of the assignments it’s possible, e. g. with selection U/I be-
ing active, to change the other value P by direct input, which can be accessed by tapping the
small ten-key pad symbol. See section 3.4.6.
The actual operating mode, while the DC output is switched on, solely depends on the set values and the situation
at the DC output (actual values). For more information refer to section „3.2. Operating modes“.
