Adjustment Limits; Changing The Operating Mode - Elektro-Automatik EA-ELR 10000 3U Manual

3.4.4

Adjustment limits

Adjustment limits are only effective on the related set values, no matter if using manual adjustment or
remote control setting!
Defaults are that all set values (U, I, P, R) are adjustable from 0
to 102%, except for the voltage with the 60 V model which is
adjustable to 100%.
The full range may be obstructive in some cases, especially for
protection of applications against overvoltage. Therefore upper
and lower limits for current (I) and voltage (U) can be set sep-
arately, 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 input is switched off, tap
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 assign-
ment between I, P and R (if resistance mode is activated). 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 3.4.6.
The actual operating mode, which is only indicated while the DC input is switched on, solely depends only on the set values.
