8. PROBLEMS & SOLUTIONS
Here below you will find the possible troubles that can occur during the normal functioning of the sealer and for each one
the possible solution.
In case you cannot solve the troubles with these instructions, put in contact with our dealer or with us directly.
8.1 Power supply
-
The sealer does not function and the main green luminous switch (n.3-pict.1.1) does not light.
a) The fuses (n.2-pict.5.17) are burnt out: replace them with new one of the same type and class
If they burn out again after the replacement, put in contact with the seller or manufacturer because it could
be a short circuit of the electrical system in the machine
b) The power cord (n.2-pict.1.1) is not connected or interrupted: connect it again or replace it
c) The microswitches SW (n.1-fig.5.5) is faulty or the cover is not closed properly and that the microswitch does
not works
-
The sealer does not function and the main green luminous switch (n°1 pict. 1.1) lights.
a) Verify that the main board is correctly powered: the led has to be lighted If it not happens, Verify the presence
of tension from the transformer TRF (see electrical diagram)
b) The safety thermostat has intervened: turning the luminous green general switch (n.3-pict.1.1) and unplug it
form the main supply (n.2-pict.1.1)
8.2 Sealing
-
The seal has some defects alongside the edges:
a) verify if the set sealing temperature value is suitable for the pouches to be sealed (see table par 4.1)
b) wait for the stabilization of the sealing jaws temperature especially if you made a new temperature adjustment
-
The seal, even if done at the correct temperature, is not strong:
follow the instructions par. 4.3
-
The sealing jaws temperature remains at the ambiance temperature:
a) Verify the red LED on the electronic control unit (see para. 5.12):
- LD3 on: outage of one or both elements (see par.5.7)
- LD3 off: failure control electronics, please contact the service
-
The seal, at the beginning, shows a shrink of the plastic material:
a) check that the sealing path is free and clean. Verify that the pouch, if it is heavy or voluminous, does not find
any obstacle in its in-feed
b) verify that the internal or external pouch edges are clean and dry, before doing the seal
c) check the sealing jaws and the a counter pressure are clean (see par.5.2)
d) check if the sealing jaws are clean
8.3 Transport
-
The in-feed motor does not stop automatically after 10 sec. from the last sealed pouch:
a) check the vertical alignment between the in-feed photocell transmitters (n.6-pict.4.2) and if they are clean. The
alignment is correct if the led lights only when a pouch is inserted
b)
check that the linking phone cord is correctly inserted into the in-feed photocell plug and in the main board
c) the in-feed area of the machine is exposed to excessive brightness of the environment; calibrate the
