6.6 Adjusting set values
As long as „ extern “ or „ remote “ are not shown in the display,
the set values for voltage, current or power can be set manually.
The mode is selected in the device setup at

Accept set va-
lue. The setting can be accessed with ->

Profile ->

General settings ->

Control panel . See „7.4 Configuring
the control panel“ for details.
Direct setting of the set values
Using the rotary knobs directly sets the set values.
The left rotary knob adjusts the voltage. The set value of the
voltage is displayed invertedly while it is selected and adjusted.
The right rotary knob either sets the set value for the current, for
the power (at models from 1kW) or internal resistance (optional,
unlockable, with U/I/R mode chosen). The selected set value
is displayed invertedly.
With the select keys
the set value for the power, with
the set value for the internal resistance or with
the set value for the current is selected.
The maximum adjustable power can also be limited.
Set values are submitted
Alternatively to the direct adjustment of set values you can
choose to set the set values only after submitting them with
the
RETURN
button. See section „7. Device configuration“ for
details. The set values can still be changed with the rotary knobs,
but are not set to the output as long as they’re not submitted.
While the set value is unchanged, only its unit is displayed inver-
tedly. If the set value is changed it is also displayed invertedly.
The
SELECT keys switch from current adjustment to power
adjustment for the right rotary knob. The chosen set values are
not submitted to and set by the power supply until then.
Pressing the RETURN button submits the set values.
Pressing the
ESC
button discards the new set values
and the old set values are displayed again.
Note: the adjustment of the resistance set value is only
accessible after the optional „internal resistance control“
is unlocked (see section 7.8).
The resistance set value is adjustable from 0Ω up to
20* Unom/Inom. Means, for example, at a device with Unom
= 65V and Inom = 10A it can be adjusted to a maximum of
130Ω.
Using predefined set values
A table of up to 4 sets of set values is accessible in the menu

Preset List
(„7.2 Predefining preset lists“). The left knob
selects the preset list and with the RETURN button the set is
submitted or discarded with the ESC button.

The chosen set is still 1. After the
RETURN
button
is pressed, the set values of set 3 are submitted to the power
supply. The display then shows the new set values of set 3 .
The ORY button can be used to jump straight to the
menu page where the preset lists are defined and there they‘re
edited and submitted with
RETURN
as usual.

6.7 Switching the button panel
The button
PAGE
is used to switch to another button
panel. The new button assignments of the other panel allow the
user to lock the control panel, switch to the function manager
or set the location mode.
6.8 Locking the control panel
The button „Lock button panel“ locks all buttons, except
itself, and the rotary knobs. The unit is now locked from manu-
al acess, so that no set value can be changed or no menu is
accessible. The locking mode can be set up in the menu. The
control panel can be either completely inactive or it can exclude
the OFF button (the unit is then locked but can be switched off
and on by the
OFF
button). See also „Control panel lock“ in
section „7.4 Configuring the control panel“.
After the control panel was locked it changes to this
icon. The button can be used to unlock the control panel again,
if button
is pressed within the next 2s.
6.9 Changing the location mode
The unit can be set up to a location mode which doesn’t allows
it to be remotely controlled or switched to remote control by an
interface card.
With the button EXT the user enables the remote control
of the unit via an digital or analogue interface card and disables
the

local mode.
With this button the user sets the unit into strict local
mode, so that it is only controllable locally (

local ), means by
hand and access by any interface, analogue or digital, is denied.
