5 – MAINTENANCE
5.1 – CHANGING THE SEALING BANDS WITH MACHINE COLD ( i.e. gripper jaws at ambient temperature )
•
HAVE YOU TO CHANGE THE SEALING BANDS WITH THE MACHINE AT AMBIENT TEMPERATURE,
BECAUSE OF A PROGRAMMED MAINTENANCE?
Pre-heat and seal comands are off; the machine is at ambient temperature; The sealing bands have little differences in
measure; for optimum accuracy it is possible to do an automatic cold balance to compensate the differences; it is possible
doing a burn-in cycle after, to become stable electric characteristics.
1 – Switch off power, release pre-heat and seal commands, let the gripper jaws getting cold down.
2 – Install the new sealing bands, switch on power.
3 – Keep the keys 1 + 2 (DOWN + UP) pressed for 6 seconds to make the AUTOMATIC COLD BALANCING
4 - Display = “ T 0 2 0 ” = 20 DEGREES – Set gripper jaws temperature or wait
(“ T 0 3 0 ” = 30 DEGREES from software release V4.9)
On the display appears the ambient (gripper jaws) temperature set on the thermoregulator.
In applications where a great precision of temperature is necessary, it is possible change this parameter and set it with the
actual gripper jaws temperature, simply pressing keys DOWN / UP.
5 – Keep the key RESET pressed for 3 seconds to start the AUTOMATIC BURN-IN CYCLE
THE MACHINE IS READY TO WORK.
NOTE: After the BURN IN cycle, sealing bands modify a little its electric characteristic, but are stable. If pay
attention can observe that temperature of sealing bands is some degree lower then before burn_in cycle. Do not
modify temperature by rotating balancing trimmer (used only in the course of first start up, after a master reset) or
pressing the up/down keys to do an automating balancing (used only after a change of the sealing band)
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.
- On the display appears “ B A L “
- Release the key 1 + 2 (DOWN + UP)
