sponds to the real value.
– The figure shows the points of intervention and the description shows the proce-
dures to be adopted.
1. Rotate main disconnector G to position “I” (ON) to activate
the power supply.
– The pilot light of button F turns on.
2. Press the push-button F .
– The pilot light of button F turns off.
3. Introduce a sample product to be wrapped in the middle of
the rotating platform.
4. Tie the trailing end of the film to the base of the product to be
wrapped.
5. Display the MANUAL FUNCTIONS screen (3) .
See “Operator interface navigation diagram (standard)”

8. Press the key C after the rotating platform has completed a
known number of wrappings (e.g. 20).
– Rotating platform stops in phase.

Number of wrappings x Perimeter of sample product (m) = Length of the
used film (m)
10. Manually cut the film.
11. Unwrap the film that was used for the wrapping.
12. Weigh the film using a precision scale.
13.
