Programmable Logic Controller

4. Loading an application
Since there is no SD card, the loading must be done by MicroControl.
Before the first load, on power-up, the PLC attempts to launch the application that does
not exist (default settings) and crashes.
To avoid blocking, press the PROG button in the first second after the power-on. This
forces the PLC to stay on the monitor. It is then possible to act with MicroControl.
5. Safety and warnings
If the device is not used as per these instructions, the safety of people and
equipment can be compromised. We disclaim any liability for any material
damage or due to improper handling or failure to comply with the safety

For all interventions on a device installed on an electric installation, the Personal Protective

carried by the worker.
In the event of a failure or malfunction, the device must not be opened and must be
returned to the factory.
