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 -> Prole ->
General settings -> Control panel.See„7.4Conguring
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conguration“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 invertedly. If the set value
is changed it is also displayed invertedly.
The SELECT keys switch from current adjustment to power ad-
justment 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.
Usingpredenedsetvalues
A table of up to 4 sets of set values is accessible in the menu
Preset List(see„7.2Predening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 MEMORY button can be used to jump straight to
themenupagewherethepresetlistsaredened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 manual
acess, so that no set value can be changed or no menu is acces-
sible. 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
Conguring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 this button
is pressed within 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.
6.10 Switching to the function manager
The SEQ button switches the display to the function
manager mode.
Switching to the function manager is only possible while the unit
is in standby (output = off). The current set values of voltage
and current are set to 0V and 0A. For details about the function
manager see section „6.15 The function manager“.
