4.1 MACHINE START UP
Rotate the main switch to position 1. After the main video page, the tunnel's present
temperature is signalled on the first line while symbols indicate the state of operation
on the second line.
Fig. 4.1.1
The states of the machine that are displayed are:
• TUNNEL OFF: power is activated but the tunnel and belt are turned off.
• TUNNEL ON: tunnel and belt turned on.
• P.FREE: belt turned on and tunnel heating switched off.
• COOLING: tunnel off but belt and ventilation turned on to allow the tunnel to cool
down.
• FREE P/ COOLING: they flash alternatively to point out that the free passage mode
has been chosen but the tunnel cooling is in progress.
The first symbol on the left represents the operation mode:
• operation with tunnel heating ( “heat shrinking” mode); The symbol appears
between brackets when the oven is in “OFF.” A bar follows that indicates the
resistor's heating state. As soon as the 5 rectangles have disappeared it is possible
to carry out the heat shrinking. Each rectangle indicates a temperature lower than
20% compared to the set value.
• indicates that the tunnel fans are turned on. By deactivating the “heat
shrinking” mode the fans remain turned on until the temperature has dropped below
80 °C.
• The letter “M” indicates the selected memory.In the 6 available memory different
values can be saved according to the various products.
• To change video pages in the menu use the keys [
×] or [Ø].
