12.4.3 Check procedure: platform adjustment
This test program controls the platform positioning. The displayed cycle value is used by the service
technician (expert) for setting and controlling position pickup. The cycle value must be between 17
(upper position) and 193 (lowest position).
Procedure:
•
Start the test program, by pressing the UP button.
With the
UP and DOWN buttons, the platform can be moved up or down whereby the cycle count shows
the momentary platform height .
•
Press the STOP button to end the test program. The machine returns to the initial position.
12.4.4 Check procedure: sealing bar temperature
The sealing bar temperature measurement is for correction of the sealing time . With the aid of the
sealing time adjustment the selected sealing time during the heating period is equalized.
*The values displayed for the front and side sealing bars are times in seconds. These time values
depend on the actual sealing bar temperature and are added to the effective set sealing and cutting
times.
For a cold machine, the desired time values can be set in the switch box at the potentiometers (Fig.
12/1, Pos. 22). With elevated sealing bar temperatures, the correction value should fall and the
operating temperature should reach zero. The programmed time corresponds to the actual sealing and
cutting time.
IMPORTANT
If the CVP extension module must be replaced in the switchbox, then the sealing time
adjustment must first be subjected to an initial calibration as otherwise the values in the test
program cannot be correctly set. For this purpose read the description “Equalizing the sealing
time adjustment”.
