6.4.4 Adjustment or User Limits
Defaults Adjustment or User Limits are 102% of full scale for all settable values (U, I, P, R).
The full range may be hazardous in some cases, especially for protection of loads 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 .
Notes:
Adjustment limits are only effective on the related set values, no matter if using
manual adjustment or remote control setting!
The set values can be entered directly using the ten-key pad. This appears when the
touch area “Direct Input” is tapped (bottom center).
The adjustment limits are coupled to the set values. This means, that the upper limit
may not be set lower than the corresponding set value. For 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 before you can adjust P-max down to 6000 W.
6.4.5 Changing Operating Modes
Manual operation of the DC load distinguishes between three operating modes, U/I and U/P
and U/R. These are tied to set value inputs made using the rotary knobs or decimal keypad.
This assignment must be changed if one of these set values is to be
adjusted and is not currently accessible.
How to change the active operating mode:
1. Unless the unit 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 below the knob depiction, or;
2. You directly tap on the colored areas with the set values, like
shown in the figure to the right. The unit next to the set
