PROBLEMS & SOLUTIONS
PROBLEM
CAUSE SOLUTION
The machine does not function and the
warning light of the main switch does
not flash
-The power cable is not correctly
insert into the wall socket or in the
machine socket.
- The fuses are interrupted
- The internal electrical circuit of the
machine is interrupted
- Insert correctly the plug into the
socket
- Check and, if necessary, replace the
fuses with others of the same kind
and the same value
- Put in contact with the manufacturer
The fuses intervene every cycle The electronic circuit of the sealing
wire is in short circuit Check if the power cables of the
resistance are correctly linked
The machine functions in a
discountinuous way The power cable is interrupted Replace the power cable
The machine functions but, after a
serie of rapid seals, does not more seal - The control electronic circuit of the
sealing temperature stopped
temporarily the machine
- The thermo protection of the
transformer intervenes
- Let the machine cool
- Let the machine cool
Pressing the pivoted plain , the cycle
starts but the machine does not seal - Sealing time on “0”
- Sealing electronic circuit interrupted
- Sealing wire interrupted
- The closing bar control micro switch
is interrupted
- Set the hand wheel as shown on
page 5
- Put in contact with the manufacturer
- Replace the resistance after checking
electrical circuit as shown on page
- Put in contact with the manufacturer
The machine does not correctly seal:
- the temperature is too low
- the temperature is too high
- The sealing time is set on a too low
value
- The sealing time is set on a too high
value
- Set the hand wheel as shown on
page 5
- Set the hand wheel as shown on
page 5
The cooling time is too short or too
long - The cooling electronic circuit is not
right set or faulty - Put in contact with the manufacturer
The seal is not perfect - The protective clothes in glass/PTF
are consumed
- The rubber of the upper mobile bar
is damaged
- The sealing wire is damaged
- Remove the sealing bar from its
place and replace what necessary
(see page 7,8 )
The sealing bar does not stay in
pressing - The electromagnet is interrupted or
disconnected
- The micro switch cycle is interrupted - Check the electrical/mechanical links
- Put in contact with the manufacturer
alarm led is lighted on - The safe electronic circuit intervenes
because of a lack in the electronic
sealing circuit working
- The 9 pins flat cable could be not
correctly insert
- Put in contact with the manufacturer
(we suggest not to use the machine)
- Check the links to the control panel
and the board n°51 pict. 11
