Communication-capable Circuit Breakers
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.
Checking the inputs and outputs on the digital input/output modules
Normal operation
After a pause of more than 2 s,
press the "Test" key.
After a pause of more than 2 s,

Table 2-14
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.
2/23
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 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 chapter on the
appropriate module.
Normal operating condition of the input/output module. The
DEVICE
inputs/outputs are either ON or OFF depending on the wiring
or communications.
DEVICE
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
DEVICE
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
DEVICE
switched by pressing the key quickly. With relay modules, you
will be able to hear a click.
DEVICE
Input or output 3 selected. With input modules, the presence of
24V DC at the corresponding input is simulated and transmitted
via the CubicleBUS.
DEVICE
Input or output 4 selected. The selected input or output can be
tested by quickly pressing the "Test" key.
DEVICE
Input or output 5 selected. The selected input or output can be
tested by quickly pressing the "Test" key.
DEVICE
Input or output 6 selected. The selected input or output can be
tested by quickly pressing the "Test" key.
DEVICE
Overall LED test. If the "Test" key is not pressed within 30
seconds, the system exits test mode.
DEVICE
The test procedure can now start from the beginning.
WL PROFIBUS Communication and Electronic Accessories • July 2004
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 the respective sections.
