6. The System Link Mode (only PSI9000)
The System Link Mode (only at series PSI9000) supports
the parallel and serial connection. Without an extra interface
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
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.
But it is recommended not 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 00A while the
whole set can deliver up to 1kW power.
6.1 Handling the System Link Mode
6.1.1 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 at a single unit.
The master also displays the
number of units connect in serial
(
6.1.2 Display of 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 distributed, so
that the master „knows“ which are connected in series and
which in parallel.

slave can be set offline with this
