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.
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 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 chapter on 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 and WinPM.Net communication system. 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.
Checking the inputs and outputs on the digital input/output modules
