6.2 Operating elements
Mains switch
Power (1)
Is used to switch the device on or off.
Selector
Mode (2)
Is used to preselect the regulation
mode in which the device shall
work. The different regulation
modes effect each other. As soon
as actual values reach set values,
the regulation mode changes. This
can, for example, lead to a dominance of the constant
power control (CP), even if the constant current control
(CC) is set as active mode. The currently active regu-
lation mode is indicated in the display. More about the
different regulation modes in section „6.6. Preselecting
the regulation mode“.
Following regulation modes are selectable:
CC
Following regulation modes are selectable:
CC
Constant current regulation
CV
Constant voltage regulation
CP
Constant power regulation
CR
10R
Constant resistance regulation in range 1*
CR
400R
Constant resistance regulation in range 2*
*the shown range values are only examples
The switchover of the regulation mode switches the load
input off and the set value that is related to the currently
chosen regulation mode is addressed for adjustment
(arrow in front of the value). Other set values can also be
accessed and adjusted in the described manner.
Note: Preselection of CV enable adjustment of the voltage
Note: Preselection of CV enable adjustment of the voltage
set value. Same applies for the resistance value and CR.
Selector
Level Control (3)
Is used to select the operation mode
between normal operation mode
(
A and B), pulsed mode (A/B) and
battery test mode. All 4 modes have
an own set of set values. That means,
that you can adjust different set va-
lues for U, I, P etc. for
A than for B. When selecting a
different regulation mode with
Mode(2) the set values
will be reset to certain default values, if the setting
Keep
set values
is set to
no
details). Using
Level Control(3) switches the load input
off, except if changed from
A->B or B->A, because these
positions are used to manually switch between the two
levels.
The most recent set values are stored inside the unit
The most recent set values are stored inside the unit
when the unit is switched off or at mains undervoltage
(power fail), and are restored after switching it on again,
if the setting
Keep set values = yes
has been chosen.
Explanation of the selector positions:
A Switches to the set values of Level A. These
A Switches to the set values of Level A. These
values become instantly active and can be
changed now.
B Switches to the set values of Level B. These
values become instantly active and can be
changed now.
A/B Switches the load offline and activates the
pulsed mode (frequency controlled, automatic
changeover between level A and B).
Battery Switches the load offline and activates the
battery test mode.
Setup Switches the load offline and activates the
setup menu. Here the device and the interface
card (if equipped) are configured.

Pushbutton
Input on/off (4)
Is used to activate or deactivate load operation
(i.e. input on/off). Input off is indicated in the dis-
play with
Standby
. Switching the input on can
be inhibited by several reasons. For example,
if an error is persistent or the input is blocked
by the REM-SB pin of the analogue.
In battery test mode, the time counting is halted or conti-
In battery test mode, the time counting is halted or conti-
nued if the button is pressed to switch the input on or off.
It is also used to acknowledge the alarm indication in
It is also used to acknowledge the alarm indication in
the display. By pushing the button, the indicated error is
cleared (as long as no alarm is still active) and the button
can be used as normal.
In remote operation, i.e. control via a digital interface
In remote operation, i.e. control via a digital interface
card, the button can be used to forcibly reset from remote
operation by pressing >3s.

New since Firmware 5.01: in mode „Battery“, the button
can be used to reset time and Ah counter, if pressed >3s
in offline state.
Rotary knob
Selection (5)
This rotary knob has no end stop. With every
position
Selection(5) selects another ele-
ment in the display resp. another parameter
in the setup menu. An arrow (->)is placed
in front of the selected element/parameter.
The selection sequence is, when rotating the knob clo-
ckwise, top left -> bottom left -> top right -> bottom right.
That means, if the arrow is pointing to the voltage set value
it will be moved to the set value for current and then to the
power set value etc.
Counter-clockwise rotation moves the arrow in reversed
Counter-clockwise rotation moves the arrow in reversed
order.
