5.2 – CHANGING THE SEALING BANDS WITH MACHINE HOT
( i.e. gripper jaws cooling down , but hot too because of inertia )
•
HAVE YOU TO CHANGE THE SEALING BANDS WITH THE MACHINE HOT, WITH THE
PRODUCTION IN PROGRESS, WITHOUT WAITING THAT GRIPPER JAWS TEMPERATURE FALLS
DOWN AT AMBIENT TEMPERATURE?
A sealing bands change, with the machine hot, with the production in progress, is less accurate then a change with the
machine cold, in a programmed mainteinance, because the automatic cold balancing must not be done (an automatic cold
balance is done to compensate the differences in measure of the sealing bands).
If the application needs a very high precision, it is possible doing a quick change of the all gripper jaws with sealing bands,
and go on with the preceding procedure of CHANGING THE SEALING BANDS WITH MACHINE COLD(see par. 5.1).
Another less expensive way to work, but easier to make a mistake, is to set the parameter of ambient temperature at the
gripper jaws temperature and doing an automatic cold balancing (do not exitate to contact our technical office)
1 – Switch off power, release pre-heat and seal commands, let the gripper jaws cooling down.
2 - Install the new sealing bands, switch on power.
- If the machine is hot, must not do the automatic cold balancing.
3 – Keep the key RESET pressed for 3 seconds to start the AUTOMATIC BURN-IN CYCLE.
- Verify if burn-in is necessary in the specific application, looking at the quality of first sealing.
THE MACHINE IS READY TO WORK.
On the display appears “ H100” , to inform that the first heating at 100
degree is in progress; next the writing H160, H100, H160, H100,
H160, H100 will appear to inform that cycles of heating and colding at
160 and 100 degrees are in progress. At the end the termoregulator will
be ready to work.
Burn in cycle can be stopped before end pressing key reset.
