OPERATION
7.1
Powering and switching on the machine
When the machine is turned on, a start-up process takes place where all internal values are
initialized and safety and control checks are carried out to ensure optimum control of the
packaging. This will be displayed on the screen with all segments flashing simultaneously for a
few seconds.
During this blinking, technical control parameters can be called up by pressing the encoder
button. These parameters may be relevant for maintenance purposes. Specifically, it will show
two parameters:
-
Vacuum pump operating hours.
-
Number of vacuum cycles performed.
The first value displayed is the operating hours of the vacuum pump. This will be identified by
the "Vacuum" icon, which will light up in the right-hand block of the screen. The digits of the
number will be shown on the central display cyclically by marking the end of the digits with an
"H". For example, if the pump motor has been running for 20991 hours, the display will
show:"2

looped.
Figure 2. Display of vacuum pump operating hours
By pressing the push-button while the number of pump operating hours is displayed, the filler
will go on to show the number of complete vacuum cycles it has completed. The value will be
displayed using the same method, changing the "H" that identifies the end of the number of
operating hours to a "C" for packaging cycles. In this case the value will be identified by the
"Repeat" icon.
Figure 3. Displaying the number of vacuum cycles performed
Press the central button again to finish displaying this value and continue the machine start
process.
Once the packaging machine is connected and the initialization process is completed (whether
or not the status values of the pump are consulted), it will be switched off, waiting for the user
to switch it on to start working.
The machine can be switched on in three different ways:
-
Using the encoder push button.
-
Rotating the encoder in any direction.
