9.8.1.2 Burn-in sealing bars
NOTICE
Only use sealing wires and sealing bars specified by the manufacturer and stated in the spare
parts list!
NOTICE
If sealing bars with new sealing wires have been installed in the machine, the following proc-
esses have to be carried out one after the other:
Calibration sealing bars – Burn-in sealing bars – Allow sealing bars to cool down – Calibration
sealing bars.
If sealing bars with previously burnt-in sealing wires are installed in the machine, only Calibration seal-
ing bars has to be carried out.
Burn-in sealing bar
1. Determine the burn-in sealing bars in Mask 102: Parameter 2/2 under the parameter "Sealing".
2. Press the function button Burn-in sealing bars in Mask 152: Calibration sealing bars. The button
changes to Burn-in is active.
The sealing bars are heated up to 250 °C for 1 second. When a sealing bar is heated up for the first
time its material resistance changes; this is also referred to as the burn-in effect.
Burn-in has been completed when the button changes back to Burn-in sealing bars.
NOTICE
Sealing bars must be calibrated after the burn-in process! This procedure is described in Mask
152: Calibration sealing bars.
