6. Troubleshooting
a. Failure during packaging cycle
COVER DOWN ERROR’’ message is display on LCD. The input signal of the
down position switch has been lost during cycle execution. Check limit switch
adjustment.
b. Insufficient vacuum
Most frequently, insufficient vacuum in bags is due to leakage in bag and not due
to any fault of the machine. Pin-hole leak for which there is no obvious explanation
is due to faulty bag material. Use bone-guard or thicker film for pin-hole leak
caused by sharp edge of the product (bone, etc.). Tear in bag by careless
handling can also be the source of the problem (sharp edge on filling table,
damage made by retailer or customer).
If no leak in the bag can be found, make sure you use a bag of the appropriate
size. Vacuum setting may also be too low. Check vacuum sensor with a remote
vacuum sensor. Sealing bar can also be jammed or sealing valve is not working
properly, see with service center. Vacuum pump may also need a check-up.
c. Faulty seal
Insufficient seal problem can be related to damaged Teflon or silicone rubber. Can
also be from a low sealing pressure, a leaking bellow or the sealing bar are
jammed. If there is no seal at all, the sealing wire may be or one of the electrical
component is not working properly (wire, sealing transformer, contactor. If the
sealing bar have a permanent current, check the contactor. In a case of non-
sticking seal, check bag quality (insufficient layer of poly PE). Seal area have to be
clean of contamination like juice and fat. In that case, use filling accessory.
Warning: Do not increase sealing time more than really necessary; higher
temperature will reduce working life of teflon and silicone rubber.
WARNING: All electrical work described in this brochure
should be done by a QUALIFIED and AUTHORIZED technician.
