4.4 Cylinder rotation control
The cylinder motor is provided with a speed variator.
7 different factory-set speeds may be selected, and speed 0 will be used for the SMART
SYSTEM (patent: regulation in accordance with humidity).
 The speed may be regulated by the user with the machine ON by pressing on the
'up' and 'down' arrows. This appears on the speed display.
The latest selected value is stored even if the electricity is cut off.
Upon starting up the machine, if the established speed is other than 0, the cylinder will turn
at speed 1 provided the detected temperature is below the operating temperature TF (130°C
by default); once this value is reached, the programmed speed is activated.
If the temperature falls below the operating temperature while the machine is in use, the
speed will adjust accordingly.
If the chosen system is 0, the cylinder will turn at speed 0 (speed defined by the sensor of
the SMART SYSTEM), regardless of temperature.
4.5 Heating
heating by electrical resistors
According to the type of machine, heating by electrical resistor takes place by modulating
the lighting of one or two units of resistors, controlled by the heating contactors.
The choice of 1 or 2 resistors is made by programming a parameter (see "Programming of
parameters").
Heating by a single unit of resistors
If the machine is configured with a single unit of resistors, there will be a special command
procedure (engagement and release of the heating relay around the setting point) in order
to reach and correctly maintain the decided temperature and avoid thermal inertia due to this
type of heating.
It is therefore normal to extend the heating contactor and frequently engage with this type of
regulation.
In order to indicate that the heating is active, the decimal point of the temperature units is lit up.
