Ironing Speed Control
The ironing cylinder motor is controlled by an inverter.
7 different factory preset speeds can be selected. Speed 0 is used for the optional SMART SYSTEM.
The speed can be adjusted when the machine is ON by pressing the UP and DOWN keys. The
speed appears on the display.
In the event of a power failure the last selected value will be recalled.
When starting the ironer, if the set speed is not 0, the ironing cylinder will rotate at speed 1 while
the detected temperature remains below TF, the operating temperature, (130
◦
C or 266
◦
F by de-
fault). Once this temperature is reached, the preset speed will be activated.
If the temperature drops below TF during operation, the speed will be adjusted.
When the selected speed is 0, the roller will rotate at speed 0 (speed set by the optional SMART
SYSTEM), regardless of the temperature.

Heating
6.5.1
Electrical Heating Models
Depending on the model of machine, the electric resistor heating operates by modifying the cur-
rent of one or two groups of resistors, controlled by the heating relay switches. The choice of 1 or
2 resistors is made by setting a parameter. Refer to Section 6.7 on page 26 for further details.
If the machine is configured to work with a single group of resistors, a special control method is
activated (closing and opening of the heating relay) to reach and correctly maintain the selected
temperature and to avoid thermal inertia due to this type of heating. It is therefore normal to hear
the heating relay engaging frequently when this method is selected.
Call for heat is indicated by the decimal point on the temperature display. Refer to figure 6.5.1.
