Operating the device

All set values are internally stored every 10 seconds
and restored after powering the device next time. Thus it
may happen, that the device does not restore the most
recent values. In order to be sure the last value you adju-
sted is restored the next time you power the device, wait
at least 10 seconds after the last adjustment and before
switching the device off.
In order to determine what firmware version is installed on
your device(s) you can either install and use the free Ea-
syPS2000 software from www.elektroautomatik.de, which
reads the device information, or you can use your custom
application. Both ways require to connect the device via
a mini USB cable and install the USB driver, which is also
available as download (for Windows only).

4.4.1 Fine adjustment

Adjusting values manually can be done in fine or coarse
steps. Switching between coarse and fine adjustment
mode is done by pushing the corresponding knob. Coarse
adjustment mode is default.
Activated fine adjustment mode is indicated in the display
with FINE. It remains until it is deactivated again or the
device is switched off.

4.4.2 Adjustment step width

Following step widths apply in dependency of the nominal
values (also refer to technical specs):
Voltage
Nom. value coarse fine
42V 1V 0.05V 3A / 5A / 6A 0.1A
84V 1V 0.1V

4.5 Control panel lock (LOCK)

The control panel LOCK is intended to prevent unintentional
use of the pushbuttons and knobs. LOCK ist activated or
deactivated using the preset button.
Activation is done by pushing the preset button three
times until the display shows following:
Figure 4
Instruction manual
PS 2000 B Single Series
Current
Nom. value coarse fine
0.01A
10A / 20A 0.1A 0.01A
A countdown will be running. During this countdown you
have two options:
a) Wait until the countdown has finished. After this, the
control panel LOCK is active.
b) Push the button once again and abort the countdown.
LOCK is then not activated.
Deactivation is done by pushing button Preset again. The
countdown will start again. If it runs out, LOCK remains
active. If the countdown is aborted by pushing the button
again, LOCK will be deactivated.

While LOCK is activated, the output can not be swit-
ched off manually, not even in an emergancy!

Device characteristics

5.1 Switching on by power switch

The power switch is located at the front. After the device
is started, following situation will be set:
• The output is off
• The set values are restored, adjustment mode is reset
to coarse
• Any condition like REMOTE or LOCK is reset.

5.2 Overvoltage

An overvoltage error can occur due to an internal defect
(output voltage rises uncontrolled) or by a too high voltage
from external.The overvoltage protection (OVP) will switch
off the output and indicate the error in the display by the
text „Error". This error has to be acknowledged first by the
On/Off pushbutton. Then the display will change to normal
display again. Also see section 4.2.2.
External voltages higher than 120% nominal voltage at
the output must be avoided, or else internal compon-
ents of the device might be destroyed!
If the cause of the overvoltage is removed, the output can
be switched on again.

5.3 Overtemperature

If the unlikely event of an overtemperature (OT) error oc-
curs by internal overheating, the output voltage is cut off
and the status token „OT" is shown in the display, together
with the text „Error". The output will automatically switch
on again after the unit has cooled down. In case this is not
wanted, the output can be manually switched off during the
overtemperature period.
