6. Trouble-shooting
6.1 Hardware problems
Problem: After switching the device on nothing happens
Reason(s): Input fuse broken, other defect
Solution: If the display remains dark, check the input fuse.
It is located inside the input socket on the rear, in a little
„drawer“. It can be checked visually or by means of a mul-
timeter. If the fuse is broken, replace with same type and
value and try again. If the error remains, contact your sup-
plier. In such a case the unit is usually returned for repair.
Problem: The display only shows „PS 2000“ after switching
the device on
Reason: An error occured during a rmware update
Solutions: Switch off device and on again, if this does not
help, try to repeat the rmware update procedure.
6.2 Software problems
Problem: EasyPS2000 can not detect the device
Reason: Various
Solution: Refer to the instruction manual of EasyPS2000
software, section „Trouble-shooting“.
7. Other applications
7.1 Series connection
Several units of preferrably same type, but at least with
identical nominal current, can be connected in series in
order to gain a higher total output voltage.
To do so, the positive DC output of one unit is connected
to the negative DC output of the next unit etc. The pos. DC
output of the last unit will then be the positive output of the
whole series connection and will have the high potential.
 Because of safety and insulation reasons it is not
allowed to connect an arbitrary number of units in series.
The DC-- output must not be raised higher than 300V DC
against ground. Thus the maximum allowed series con-
nection voltage is 342V for 42V models and 384V for 84V
models. For a series connection with such high voltage
extra measures for safety have to be taken.
 If units with different nominal current are connected in
series, the unit with the lowest nominal current will deter-
mine the maximum current of the system.
 If one or several units change into current limitation,
the desired output voltage can not be achieved anymore.
 In a series connection, only the positive or negative
DC output of the rst unit (the one with the lowest potential)
may be grounded.
Operating the device
7.2 Parallel connection
Several units of preferrably same type, but at least identical
nominal output voltage, can be connected in parallel in
order to gain a higher total output current.
Every unit has to be adjusted seperately (manually or
remotely by a PC). It is recommended to adjust the output
current to the maximum and the output voltage to identical
values on every unit.
 If units with different nominal output current are con-
nected in parallel and the unit with the lowest nominal
current changes into current limitation it will drop its output
voltage and will thus not be available anymore as current
source in the parallel system, unless the output current is
sinking again below the limit.
7.3 Remote control with EasyPS2000
The device can be remotely controlled via the USB port
by means of a PC and a Windows software called Ea-
syPS2000. The software and a USB cable are included in a
seperately available kit. The device requires a license code
to be unlocked in the software. The code can be purchased
as an option. Further information are available upon request
or in the instruction manual of the EasyPS2000 software,
as well as on our website. In order to purchase the kit and
the license code, contact your dealer or send an e-mail to
[e-mail] and state article number
and serial number of the device.
7.4 Programming
The device can be programmed and remotely controlled
by custom software and via the USB port. This port is enu-
merated as virtual COM port on certain operation systems
(currently: Windows only). This enables the user to easily
implement the device into the target application.
The programming documentation is available on the web-
site of the device manufacturer in the download section
or upon request. When programming custom software no
device license is required.
The connection to the PC is done a standard mini USB
cable.
7.5 Firmware updates
The device rmware can be updated if necessary. Details
about rmware updates and the procedure are in the in-
struction manual of the software EasyPS2000, which can
be found in the seperately available software kit or on our
website. Only this software can be used to update a PS
2000 B unit.
The update feature of the software does not require the
license code.
