9.3 Device reset
The "Reset device" function allows to interrupt all the functions in progress and to set to the initial condition. This function cancels the alarms and
anomalies present, if any.
1. Press and hold "OK" until the configuration menu is displayed.
2. Press "OK" under "Forcing".
3. Using the arrow up, move to "1.8 Reset device" and press "OK" (see the instruction sheet H0005275).
4. Using the arrows, change "OFF" to "ON" and press "OK".
5. Wait for the device to reset.
9.4 Electrical installation
The electrical connections must comply with the technical specifications in this manual, strictly adhering to the attached wiring diagrams.
CAUTION: Risk of electric shock. Cut off the electric supply before carrying out any work. Failure in following these instructions may
result in injury of persons or damage to property. The installer must provide an electrical line equipped with an automatic differential
release system upstream of the machine main switch and a suitable earthing system that meets all the requirements of the accidents
prevention standards.
The electrical panel is inserted inside a box of PA6G30 (polyamide reinforced with 30% glass fibre) IP 42. Connect the 230V electric supply to the
appropriate connectors L - N and make the connection to earth, using the cable gland provided. Probes and actuators are factory wired and therefore
do not require connection.
Comply with the instructions on the label inside the device and the enclosed diagrams: the wiring must be carried out by qualified technical personnel,
respecting the regulations in force.
The wiring must be carried out properly by qualified technical personnel and in compliance with the directives and standards in force
in the country of installation.
For the electrical supply connections of the device and the low voltage elements for power supply, it is necessary to comply with the
applicable regulations in force using cables with cross section and insulation suitable for the place of installation and suitable pipes or
protection pipes.
9.5 Cables wiring and positioning
To access inside the controller, use a flat screwdriver, insert it into the side slots and gently
pry it to open it. Connect the 230 V electric supply to the appropriate connectors L - N
and make the connection to earth, using the cable gland fitted. Cable H05VV-F 3G1.5 or
with superior features according to current legislation. Cable gland PG11 external diameter:
5-9 mm. Probes and actuators are factory wired and therefore do not require connection.
The electric supply cable insulation must comply with the standards applicable to the
environment (or room) in which the device is installed
Before commissioning, check the correctness of the earthing and of the
interruption and protection devices.
When installing the electric supply cable and other cables, do not touch the
electronic board and its components. Avoid the formation of chips and strands
and minimize the cables length to prevent them from damaging the board.
