3.4 Power supply
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.
o avoid blocking, press the PROG button in the first second after the power-on. his
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
instructions.
he interventions on the devices must be made by staff who are competent to work on
electric installations.
Before all interventions, all power supplies must be switched off. he cutting devices on
the installation must be dimensioned and placed according to the standard U E C
15-100.
For all interventions on a device installed on an electric installation, the Personal Protective
Equipment (PPE) as defined by the safety regulations on the electric installations must be
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.
Observe the following pictograms:
Attention.
On the product label this symbol means that the notice must be consulted.
In this manual, this symbol indicates important information.

his device is CE approved and complies with the national and European
guidelines.
6. rotection device
Quick fuse protections must be positioned on the 24 volt continuous start feeding the
PLC. hese fuses will be sized according to the number of devices set in series behind the
start.
7. Elimination
Old electronic devices are recyclables goods that should not be thrown into the
trash can. If the device reaches the end of its life, it should be eliminated in
accordance with the legal regulations in force to the recovery centres in your
municipality. Elimination in the household trashes is prohibited.
8. Cleaning
For cleaning, use a clean, dry, antistatic, lint-free cloth without corrosive products.
9. Technical features
