Elektro-Automatik EL 9000 B Slave serie Betriebsanleitung Seite 61

There are several possible combinations of standard models and Slave models:
2.3.2.2 AC supply
Connection to mains of electronic loads of EL 9000 B Slave only requires a standard wall socket. The mains cord is
included in the scope of delivery. The devices only consume little power, so there are no further installation or safety
measures required. The loads can also be operated together with different devices on the same distribution box.

Combination 1:
Multiple EL 9000 B (with display)
All models of the standard series can be combined to
themselves in master-slave (up to 16 units on one bus)
Advantage of this combination: every unit could be master
or slave; the slave show their own actual values and the
entire system can also be controlled manually.
Disadvantage of this combination: higher costs compared
to a system with EL 9000 B Slave models
Combination 2:
One EL 9000 B with one or multiple EL 9000 B Slave
This is the intended combination for models of EL 9000 B
Slave series, as it can be found in the cabinets of series
EL 9000 B 15U and EL 9000 B 24U, for example.
Advantage of this combination: lower costs
Disadvantages of this combination: in case the master
fails, the entire system cannot work. After reconfigur-
ing any Slave unit to be master, which can be done via
software and remote control, the system can continue to
operate. Other: only specific models of both series can
be used.
Combination 3:
Multiple EL 9000 B with one or multiple EL 9000 B
Slave
An already existing MS system with only EL 9000 B is
going to be extended by one or multiple EL 9000 B Slave
units.
Advantage of this combination: in case of a failing master,
any other EL 9000 B unit can be quickly reconfigured to
be master.
Disadvantages of this combination: higher costs, because
even some of the slave units may have a display and
control panel which they actually don't need. Other: only
specific models of both series can be used.
