12. The System Link Mode (PSI9000 only)
Attention! Following requirements and restrictions:
• Parallel and/or series connection only with units of the
same type
• Models with option ZH can not be used for System Link
• The softwares EasyPower and EasyPower Lite don‘t sup-
port remote control of units in System Link mode
The System Link Mode is only available for series PSI9000
and supports parallel or/and serial connection. Without this
extra connection any device will display its own actual/set
values and errors, when using the devices in master-slave
configuration in parallel or series or in parallel with the Share
bus. The set value and actual value of voltage has to be
multiplied by the user by the number of serially connected
units. The parallel connection acts analogously to the serial
connection. Here the current set value and actual value have
to be multiplied.
The System Link Mode transfers the actual values from the
slaves to a definable master and the set values vice versa.
The master displays and sums up all actual and set values,
so that the connected devices act like a single unit. There
are also signals, warnings and alarms of all slaves indicated.
The System Link Mode supports up to 30 connected units. It
is though not recommended to link more than 10 units when
using parallel connection.
Example:
Four devices PSI 9080-100 shall be linked. Each of them
can deliver 3kW power. If you serially connect two sets of
units which are connected in parallel, it results in a maximum
voltage of 160V and a maximum current of 200A while the
whole set can deliver up to 12kW power.
12.1 Handling the System Link Mode
12.1.1 Display and handling of the master
The master unit is used to adjust the set values for the whole
system and to display the summed up set values and actual
values.
The configuration of the master
defines the „behaviour“ of the
whole system. All values can be
set like with a single unit.
The master also displays the
number of units connect in serial
(
 s2) and parallel ( p2).
12.1.2 Display at the slaves
See below the display of a slave as long it is „online“ with
the master. Any device in the linked system has to be set up
for the System Link mode. You need to speficy which unit
will be master and how the slave units are connected, so
the master will „know“ which are connected in series and
which in parallel.
Example: the slave is online and
the power output of the system
is in standy (switched off). The
(1,2) shows that this slave is
directly connected to the master
in parallel (the second value
indicates the number of units
in parallel).
If the output is switched off, a
slave can be set offline with the
key and is then not
linked to the master anymore.
Now it can be configured.
M
The MENU key activates the menu.
LINK
The LINK key is used to set the slave online with
the master again.
