2. Specify the unit as master with tough area . A warning requester will
appear which has to be acknowledged with OK, otherwise the change will be reverted.
3. Accept the settings with the touch area and return to the main page.
Step 3: Initializing the master:
The master unit and the whole master-slave system must
now be initialized. This is done automatically after the
master unit has been activated for M/S operation. In the
main page, after quitting the setting menus, a pop-up will
appear (see image on the right).
Tapping INITIALIZE can be used to repeat the search again,
in case the detected number of slaves is less than
expected. This can be necessary if not all units are set as SLAVE or the cabling/termination is still
not OK. The result window shows the number of slaves and the total current and power of the
MS system.
In case there are no slaves found or not present,
i.e. not powered, the master will still initialize the
M/S system with only itself.
Note: The initialization process of the master and the master-slave system will, as long as M/S
mode is activate, be repeated each time the units are powered. The initialization can be
repeated at any time via the MENU in GENERAL SETTINGS.
8.2.5 Operating a Master/Slave System
After successful configuration and initialization of the
master and slave units, each unit will show its status in
the displays. While the master merely shows “Master” in
the status area, the slave(s) unit display will continuously
display as shown to the right, as long they are in remote
control by the master:
This means that as long as a slave unit is controlled by
the master, it will not display any set values, but actual values (measured), and it will show the
DC Input status and possible alarms.
The display on the master unit changes after initialization and all set values are reset. The
master now displays the set and actual values of the total system. Depending on the number of
units, the total current and power will multiply. The following applies:

The master can be treated like a standalone unit

The master shares the set values across the slaves and controls them

The master is remotely controllable via the analog or digital interfaces

All settings for the set values U,I and P (supervision, limits etc.) should be adapted to the
new total values

All initialized slave units will reset any limits (U
Min
, I
Max
etc.), supervision thresholds (OVP,
OPP etc.) and event settings (UCD, OVD etc.) to default values, so these do not interfere
with the master settings. As soon as these values are modified on the master, they are
