WL Circuit Breakers - Siemens

External CubicleBUS Modules
WL Circuit Breaker
Testing the Digital Input and
Output Modules
The test should be performed prior to any
commissioning work to determine whether
the circuit breaker and its components
function properly.
The test mode can be used to check that
the CubicleBUS modules function properly.
A distinction must be made between the
individual modules.
Pressing the “Test” key on the CubicleBUS
module starts the test mode, and all the
inputs, outputs, and associated LEDs are
deactivated. The DEVICE LED changes from
green to yellow.
Pressing the “Test” key several times
in quick succession then switches the
corresponding input or output ON and
OFF alternately.
With the input module, the input signals
are also transmitted via the CubicleBUS and
via the COM15/COM16 if connected.
With the digital output modules, the
associated outputs are also switched,
thereby enabling the system to be checked.
The test mode of the analog output module
and the ZSI module is described in the
section for the appropriate module.

The inputs on the input module, outputs on
the output module, the ZSI input, and the
ZSI output can be ”forced‘’ via the BDA.
The test mode can be activated via the
communication system and the inputs and
outputs overwritten for test purposes.
The system exits the test mode
automatically after 30 seconds if the test
key is not actuated or no changes have
been made via the communication system.
The test scenarios for the analog output
module and ZSI are explained in their
respective sections.
Normal operating condition of the input/output module. The
inputs/outputs are either ON or OFF depending on the wiring
or communications.
The module switches to the test mode, as indicated by the
yellow DEVICE LED.
Pressing once selects input or output 1, as indicated by the green LED
1. The output can then be switched on or off, and the ON or OFF signal
of the input can be transmitted by pressing the "Test" key quickly (1 s).
Input or output 2 selected. As with 1, the output can be
switched by pressing the key quickly. With relay modules, you
will be able to hear a click.
Input or output 3 selected. With input modules, the presence of
24V DC at the corresponding input is simulated and transmitted
via the CubicleBUS.
Input or output 4 selected. The selected input or output can be
tested by quickly pressing the "Test" key.
Input or output 5 selected. The selected input or output can be
tested by quickly pressing the "Test" key.
Input or output 6 selected. The selected input or output can be
tested by quickly pressing the "Test" key.
Overall LED test. If the "Test" key is not pressed within 30
seconds, the system exits test mode.
The test procedure can now start from the beginning.
The table shows the test procedure for checking the digital inputs and outputs on the CubicleBUS. If the “Test” key is not pressed within 30 seconds, the
system exits test mode automatically.
