PROBLEM CAUSE CONSECUENCES SOLUTION
EXCESSIVE FLOW
The products to be
packed are too close
together.
A signal it is present that
does not cause a
stoppage of the
machine.
Increase the distance between
the products in the machine
infeed.
UNWINDER PROBLEM
The film unwinding
system is not working
correctly.
The machine goes into
alarm conditions when
the reel unwinder motor
stays on for too long.
Make sure the film is unwinding
correctly.
Check the closed position of the
lever located on the reel holder.
Verify that the tensioning bars
are working correctly.
OPEN UNWINDER
The movable hatch on
the reel holder is not
closed properly.
The automatic functions
of the machine are
disabled.
Close the movable hatch on the
reel holder.
Check the lever on the reel
holder is in the position at
which the contrast roll is
closed.
BAR MOVEMENT
PROBLEM
Anomalous movement
of the sealing bar has
been detected or the
sealing bar does not
move.
- Problems with the
sealing bar safety
sensors.
- An obstruction has
hindered the sealing
bar during operation.
- Malfunction on the
encoder signal.
- Problems of motor
operation.
- Make sure there are no
foreign objects blocking the
movement of the sealing
bar.
- Check that the mechanical
parts that allow the
movement of the sealing bar
do not impede its proper
functioning.
- Check the right functioning
of the inverter 16.U.1, the
motor and the encoder
signal 18.E.1.
BAR UNDERTEMP
[BAR
UNDERTEMPERATURE]
The sealing bar is not
able to reach the set
temperature.
The problem may be due
to low voltage.
Temperature problems
with the probe.
Check the working order of the
sealing bar and correct
temperature control. (check the
14.TC.1 thermocouple of the B1
element and the 14.TC.2
thermocouple of the B2
element).
Check the working order of the
resistor.
SEALING BAR
OBSTRUCTION
[OPTIONAL]
Detected an obstruction
in the sealing bar zone.
The sealing bar does not
move.
Remove the obstruction.
MOVABLE BELT PROB.
[MOVABLE BELT PROBLEM]
An operational problem
with the conveyor belt
approach system has
been detected.
The machine stops.
Check the mat's mechanisms
are not blocked.
Check the working order of the
movable mat's sensor, 24.SQ.1
