External CubicleBUS Modules
By connecting additional,
external modules to the
CubicleBUS, breaker status
information can be displayed
and data read from the
switchgear to the system.
This enables cost-effective
solutions to be implemented
for automating other devices
in the switchgear.
General
External CubicleBUS modules
enable the WL Circuit Breaker to
communicate with secondary
devices in the switchgear. They can
be used, for example, to activate
analog displays, transmit circuit
breaker status and cause of trip,
and read additional control signals.
One module is also available for
zone-selective interlocking.
Five different CubicleBUS modules
can output data from the CubicleBUS
system (four digital output modules
and one analog output module). A
digital input module can transmit
data from the switchgear to the
PROFIBUS master, and a ZSI module
enables zone selective interlocking
among the circuit breakers.
In this example, the rotary switch

has been set to function "0.2".

Rotary Switches
With the exception of the
configurable output module, all
external CubicleBUS modules are
configured using rotary switches.
The arrow on the rotary switch
points to the function that is
currently active. With certain
modules (e.g. digital output
modules), the group selection
(e.g. "1st Module" left; highlighted)
and then any other settings (e.g.
time delay) must be taken into
account. More information on this
is provided with the individual
module instruction sheets and the
WL Instruction Manual.
All external CubicleBUS modules have the same housing. The CubicleBUS can be connected
Figure
to X1 and X2 with an RJ45 plug or a terminal connection made to X3. This depends on
2-10
whether a COM15 module is available.
WL Circuit Breaker
Installation
The external CubicleBUS modules
can be installed onto a standard
35mm DIN rail on the panel.
The cable for connecting the first
module to the circuit breaker must
be no longer than 2m.
Prefabricated cables, which can
be ordered separately in different
lengths, must be used to connect
the CubicleBUS modules to each
other and to the circuit breaker.
These cables enable the various
components to communicate and
supply the CubicleBUS modules
with 24V DC.
