Chapter 3. Machine adjustment and setting up
3.2. Adjustment
In case of "ANOMALY" the display will show as follows:
A 1 "Emergency Pushbutton" alarm.
Emergency pushbutton (9) is held down.
Release the button by turning it to the right. Afterwards press START button (5).
A 2 "Inverter" alarm.
Check the failure coding on the inverter display arranged on the electrical installation.
Check for the reset procedure on the inverter user manual (supplied with the machine).
A 3 "Motor Thermal Switch" alarm
Check the correct operation of the fan wheel motor.
A 4 "Temperature" alarm.
The temperature has exceeded 230°C or the probe is interrupted.
Check the probe and the relating connections.

3.3. Air flow adjustment

It is possible to adjust the air flow on the product to pack by acting on the knobs (11) (figure 3.3.A page 52). The rotation
of knobs (11) determines the position of the flaps (12) (figure 3.3.B page 52) which drive the hot air flow into the desired
direction so to obtain the best shrinking.

3.4. Conveyor belt adjustment

Tunnel 50: Adjust the height of the conveyor belt with the special screws (13) (figure 3.4.A page 53).
Through adjustment of handwheels (14) fitted on conveyor belt it is possible to get the belt rollers (15) turn
or make them idle ones (figure 3.4.B page 53).
Turning handwheels clockwise (+), rollers (15) will not turn.
Turning handwheels counterclockwise (-), rollers (15) will turn.
N.B.: Such an adjustment shall be done when conveyor belt is moving.
Adjust curtains acting placed on tunnel inlet on the proper knobs (18) to get them at the same level of
tunnel belt (figure 3.4.A page 53).
Tunnel 70: Proceed as follows to adjust belt height: Loosen knobs (16) and turn handwheel (17) (figure 3.4.C page 53).
Through adjustment of handwheels (14) fitted on conveyor belt it is possible to get the belt rollers (15) turn
or make them idle ones (figure 3.4.C page 53).
Turning handwheels clockwise (+), rollers (15) will not turn.
Turning handwheels counterclockwise (-), rollers (15) will turn.
N.B.: Such an adjustment shall be done when conveyor belt is moving.
Adjust curtains acting placed on tunnel inlet on the proper knobs (18) to get them at the same level of
tunnel belt (figure 3.4.C page 53).

Chapter 4. Limits and conditions in the use of machine

4.1. Max. weight and dimensions of the package
Tunnel 50 a = mm740
Tunnel 70 a = mm800
NOTE: The weight to be considered is the total weight distributed on the conveyor belt, and not the one of the single package.

4.2. Machine operating conditions

!
Do not carry out packages whose dimensions are equal to the tunnel passage. Leave at least 5 cm. on each side.
!
Do not carry out packages whose dimensions are lower than the rods pitch of the conveyor belt.
The product fall between the rods could cause remarkable damages to the belt itself.

4.3. Items which must not be packed

!
Pressurised gas cylinder of any kind
!
Bulk and volatile powders
!
Any materials and products not listed but which might harm operator and cause damages to the machine.
