Adjustment Procedures

To insert a sensor support into the right-hand journal of the bottom roller, the belt tensioner assembly has to be removed first (already removed in figure 32). Use the small screwdriver to remove the retaining clip from the tensioner arm pivot axis.

See figure 32.

After disassembly of the belt and tensioner, the supports can be inserted (1) as previously described.

Now, push and rotate the nip adjustment knob until the pin, mounted in the knob, falls into the first notch (relative to top) from the indent bracket.

See figure 33.

Pressure will be applied to the pressure sensors, and the pressure can be read on the

PDU.

To change the pressure, place the 10mm open-ended spanner on the M6 nut, that’s

directly under the compression spring (so, the upper jamnut).

On the left-hand side of the machine, it’s best to remove the blue connector from the overtemperature switch, to ease access with the spanner. See figure 34.

Rotate clockwise to decrease the pressure, counter-clockwise to increase the pressure

(seen from above).

The pressure settings for each PDU display

(so, for either side of the machine) should be as follows:

ProSeal 25 – 35 kilograms.

ProSeal 44 – 46 kilograms.

fig. 33

If necessary, change these values as described above.

After the adjustment, remove the pressure sensors and the supports.

Assemble all parts in reverse order.

Now, it is mandatory to continue with the Nip Adjustment Procedure described in Section 5-2.
